What is the likelihood of this occurring in the next 50-100 years? Is technology really expanding now at an exponential rate? If so might this ever come to be true in our lifetime? pls answer.

>> No.6681478

The dream of space travel is dull and bland, and I doubt it's going to ever happen with our limited resources. You should think of advancement as something associated with nature more so than technology. The true dream of the future is evolution, through nature, and the prosperity of our species,

It really depends on whether FTL is possible. I really have no idea, Einstein says no, nothing in the quantum theory I know of permits it, so even if it is possible, it will probably take a full century to get it working

>> No.6681498

If we keep running at this rate, we're going to need a few planets and moons to support us in that amount of time (50-100 yrs). The most pleasant way for the governments of Earth is to expand into our neighboring planets and asteroids (since they lose power in every other scenario). So, with huge funding, I guess we could expect to mine in the asteroid belt and the Moon, or maybe even live in Mars using life support. But don't expect interstellar travel and colonies in our lifetime.

Pic related and his project is possibly the most serious minded experiments that could lead to FTL travel ever undertaken. Results have been so far inconclusive and the underlying physics is impractical at best, tenuous at worst.

The EmDrive breaks conservation of momentum. 90% sure the new results are as flawed as the FTL neutrino fiasco. Notice the intentionally broken version of the drive produced the same level of thrust?

That's why we're planning on going to asteroids (and Mars, but that's mainly just for achievement and colonization; like landing on the Moon); not just to understand them, more, but to mine them for resources.

>intentionally broken version of the drive

The only difference was that the "working" drive had slots on the bottom, which according to Cannae were vital for the drive's function, and the "broken" drive simply lacked these slots. Which just means that the drive's function is not dependent on the slots, and the guys who designed it had seemingly reason why they built it that specific way or why they included the "vital" slots.

>> No.6681531

Let's get real here. Even if it is possible to use the EmDrive or "warp drives", our resources are scarce and the world economy is in deep shit. We can't build ships that can make interstellar travel or even solar travel today. But maybe, if we can build self-contained robotic mining colonies that can mine ore from nearby asteroids and the Moon in the next few decades, we could become prosperous enough to build a Martian colony by the end of this century. And if we can continue mining and industry on Mars, we can go even deeper into the solar system (Europa, Io and other moons). If we're lucky enough, we could actually build sleeper ships with extremely powerful drives. Those ships would travel at approximately 0.4 c and would use time dilation and hibernation in tandem to prevent aging. And their engines could harvest the theoretical particles called gravitons (carrier particles of gravitational force) and use them for thrust.

The main problem of such an interstellar civilization would be communication. Our current technology seems to have reached the physical limit of communicational speed (speed of light) via fiberoptics. However, this isn't enough, as light takes four years even to reach the second-nearest star (losing only to the Sun) Proxima Centauri, not the mention the round-trip. And the nearest extrasolar planet that is thought to be able to support life is 16 light years away (Gliese 581 f). Earth cannot possibly rule her extrasolar colonies, so they have to be established by independent corporations and coalitions. This could as well pave the way to an interstellar war, which would destroy parts of colonies.

Tachyons, if they even exist, could be a solution to this problem. Tachyons are theoretical particles that travel faster than light. If we encoded data on them, this would reduce the time it takes to communicate.

An even better and actual solution would be to use quantum entanglement, which is a state where particles are codependent in their states (eg. if one of the entangled pair is up, the other pair must be down). Even today, there are a few successful attempts at this but a conventional light signal must also be sent, effectively reducing the speed to the speed of light. It is more of an engineerung problem to remove light from quantum communications, and if it is ever solved, it would mean instantanious interstellar communication.

What's even the point of an interstellar civilization/empire? Those are mostly just analogs to civilizations of the past used for dramatic effect in games and stories. Those old empires were dependent on colonies for ressources and trade. On interstellar scales this becomes nonsensical.

Every civilization advanced enough to engage in interstellar travel would have lots of natural ressources in its own system at its immediate disposal. There are no metals elsewhere that wouldn't be already here. Why mine ore or rare earth metals in a planetary system lightyears away if you could dig up the stuff from earth itself at smaller costs than fitting an interstellar mission + mining operation. Of course this might change if interstellar shipping gets dirt cheap. As cheap as overseas shipping. There would be no incentive for trade, since the colonies couldn't provide the export value to balance their initial imports in advanced goods they can't yet produce on their own. The only interesting export goods would be biological material exclusive to the colony. But anybody buying these goods needs to pay enough to pay for what colony imports.

Mass colonization and emigration may also be economically unfeasible unless interstellar spacetravel gets as cheap as operating a seaferry. It's more likely that population stops to grow on Earth and emigration to stop overpopulation becomes a non-issue.

The only sensible purpose for instellar colonization would be research and exploration as well as the intentional spreading of humanity in the galaxy to counter extinction of the species on a planetary scale. The authorities would have to provide the initial ressources for the colonies for virtually free, because it's economically unfeasible as a business. Assuming interstellar travel is expensive. Again, if it's dirtcheap everything becomes a non-issue and people could fly around the galaxy on their own like in Star Trek or Star Wars.

He's got some interesting experimental results. And if HIS work pans out, then FTL travel might actually be possible.

FYI: take this with a grain of salt, but I've heard that all of Sonny White's 'positive' results in the warp experiments at Eagleworks are the result of changes to the apparatus that conform it to Woodward's theories.

>> No.6681667

Even if overpopulation stops being an issue, our resources would be completely drained and Earth would be near-uninhabitable due to extreme pollution caused by overpopulation and the depopulation event. We would pretty much have no choice but to develop robots from synthetic materials using minimal iron and to go mining out in the asteroids. And as Earth would not be self-sufficient anymore, there would be significant research on extraterrestrial agriculture (hence the Martian colony). However, agriculture can also be done on Skylab-style sattelite farms. Maybe we can even live in orbital habitats and live on synthetic nutrition. I can imagine a habitat station orbiting over Martian farms that are under glass-like insulation, being supplied oxygen by its vegetation and hydrolysis.

Maybe we will decide to screw all this and transfer our minds to a Matrix style network, but that's an entirely different topic.

It was a control unit, to validate their measurement process. It's very easy to measure thrust that doesn't exist, or is generated by something like magnetic interaction with nearby equipment.

After the setup demonstrated that they were incompetent experimenters (the control and test unit showed the same amount of thrust), they demonstrated incompetence in interpretation of the results by trying to claim that this validates their system, rather than invalidates the experiment.

Why is everyone talking about FTL and interstellar travel?

There are many millions of times the resources available in Earth's crust, atmosphere, and ocean in our solar system.

Without going to any other stars, we can develop beyond the typical sci-fi depiction of a "galactic civilization", and have the equivalent of thousands of independent occupied planets.

I think it's very plausible that expansion into space will be in full swing fifty years from now.

Assuming Earth becomes a hostile environment, why would space be favorable? Space requires artificial gravity and includes the risk of decompression. Both of which wouldn't be an issue on earth, plus earth has some radiation protection. If you have the ressources to conduct off-world mining operations you could surely excavate some landfills, look for metal or other ressources and make them reusable. And if you can grow plants on a space station you can grow plants in an isolated greenhouse on earth.

Maybe...but it seems implausible. You're going to send a message to another colony and hope that
(1) The software bug you hope to exploit is still unfixed 10-50 years later.(The time to transmit your message)

(2) They don't screen any of the messages coming in through their few expensive receiving dishes.(They would have to be more or less actively complicit in their self-destruction, you can't direct transmit from another solar system to a mining drone.)

And to what benefit? Why attempt to destroy a colony that is physically separated from you for the foreseeable/distance future?

>> No.6681726

I guess you're right, but most of Earth would be uninhabitable and inarable, so some of the remaining population, regrettably the richest ones, will be able to transfer themselves into upper-orbit habitats built resource-efficiently. Also, we could use genetic engineering to adapt the crops to suit the needs of a post apocalyptic world. But again, the richest would claim most of them, leaving some of the world still depending on synthetic nutrition.

Thinking about it now, my dreams about interstellar travel are crushed. But thanks anyway for the point of view.

>more likely to attract meteroids than a space station
Not significantly. They go very fast. If they're not on a collision course without gravity pulling them in, few are going to be pulled into a collision by gravity.

Furthermore, many (especially the numerous micrometeors) will burn up in the atmosphere, even Mars's thin one, and even more will be blocked by Mars itself, which covers 50% of the sky.

>no advantage in radiation protection
Again, there is Mars itself, covering 50% of the sky. There's also ample material handily available for shielding.

>What's the point
Mars gives you aerobraking (so you don't have to match velocity with it, you just have to collide with it the right way -- Mars is just about the lowest delta-V target to hit), the atmosphere and regolith are omnipresent resources, you have a whole planet's worth of localized resources to explore and exploit, there's a decent amount of gravity without any complex and hazardous spinning sections, etc.

Asteroids and the Moon have their advantages, but Mars is clearly a top contender for the best place to colonize first.

The main reason spaceflight is so expensive is that we don't have efficiently reusable launch vehicles.

In terms of raw energy costs, getting to orbit is actually not all that much worse than intercontinental flight. Remember that jets fly on pure hydrocarbon fuel. Rockets might be mostly propellant tank, but most of that propellant is liquid oxygen, which can be extracted from the air with little expenditure of energy.

SpaceX and Blue Origin are both working on a clearly feasible approach to efficient reusability: propulsive flyback and landing. Others are working on spaceplane designs. SpaceX's design is already being flight-tested on orbital launches, and their all-reusable system could be in full operational mode within a couple of years.

So when this technology is ready, all we'll need is cheaper energy to make spaceflight as cheap as today's planes. Advancing solar power technology has the potential to provide us with huge surpluses of energy, perfect for producing rocket fuel.

It stands to reason that there is probably rocky debris around proxima centauri to at least the same distance. We just haven't seen it because we don't have sufficiently good telescopes.

He means from the point of view of the travellers, not from the people staying around the stars.

As you get up to light speed, it's as if the universe shortens in the direction you travel, so you can travel any distance in arbitrarily small subjective time, even though you can't exceed light speed.

So, in theory, you can travel to another galaxy before you get hungry for lunch, then get back before you're ready for supper, but your wife is mad at you for being so late that the nice meal she cooked had time to evolve intelligent life on it.

And if the proxima oort cloud covers half the distance from the proxima side and the sol cloud covers half the distance from the sol side, Then there is a continuous cloud of debris covering the full distance between us and our nearest neighbor....new observations do not bode well for the prospects of relativistic speed exploration.

That said, there have been many an occasion that we nearly lost earth due to chance, and the cause of said destruction would not have come from us.

The only way in evolve and advance is to secure a safer home in the void and the resources that are waiting for us. Also, if you haven't been paying attention, it was technology which brought our prosperity. You want to be a Luddite, that's fine, don't drag me with you. You can even stay on this planet and be with your nature when nature finally flings a gigantic fucking rock your way that won't just barely miss.

In the end though, I doubt we will see definitive space travel in the next 500 years. But we will see ti eventually. We already know the other worlds are full of exploitable goodness, and we are started to find ways to get at them. When we start exploiting our asteroid belts, things will become significantly less strained.

If it the capture is anywhere near complete, it's equivalent to accelerating the mass of what you collide with. You'd have to lose much of the material in a forward direction for it to cause a reverse acceleration proportional to the energy of the impact rather than the inertia of the impactor.

An impact with a stationary microgram dust grain might knock apart a gram of material from the shield. If you capture that material and reassemble it into a shield layer, that's a gram of replacement material you didn't need to accelerate.

"An impact with a stationary microgram dust grain might knock apart a gram of material from the shield."

It is roughly an elastic collision. The "knocked apart" material is now moving towards you with the energy of the dust grain, if you stop that material, you decelerate. There isn't a free lunch here. Maybe you prevent the damage to your ship, but ultimately, the energy lost dealing with that dust grain will be the energy required to accelerate it to your speed.

Practically, there will be some matter to energy conversion in a collision that energetic, so some of the energy will radiate laterally, but I don't think you can count on it being that much.

It's moving toward you with the momentum of the dust grain. It's expanding in all directions with the energy of the dust grain.

In an epic scale closed-sided whipple shield constructed of atom-thick aluminum foil, for instance, most of the vaporized material from a typical impact would coat the next layer and the side walls. Periodically, you would cut a couple of layers off (with side walls), move them to the back and reconstruct them at the proper dimensions.

> the energy lost dealing with that dust grain will be the energy required to accelerate it to your speed.

At that speed angle is irrelevant, probably better to model the dust as a particle cloud, because the energy in the bonds is much less than the energy of the collision. Even if there were deflection, your ship would just be accelerated to the side and you'd need to expend energy to right your course.

With respect to fields, the particle exerts a force on the field, and the field exerts a force on the ship. So you still lose the same energy.

You clearly claimed that capturing any ablated mass of the shield was equivalent to accelerating enough mass to replace the ablated portion, in defending your earlier idiocy of saying we'd need a "limitless quantity of mass to continuously rebuild our ablative shield".

Anyway:
>Practically, the cost to survive the impacts along our journey is the cost to accelerate a mass equal to all the mass in the cross sectional area of our path.
This sets no minimum cost on moving mass between stars. It may be a reason to build a longer, thinner vehicle to fit behind a smaller shield.

I'm not changing the subject. You said it would be just an "engineering consideration" I agree. There is no physical law preventing building a craft with an arbitrarily large ablative shield. If you expected me to argue it was in violation of physical law, you'll have to go find another rube.

Where we disagree is that I don't think this will be practical. I think that engineering problems are often hard and often harder than we think they are even when we recognize that they're hard.

Not changing the subject, changing your position from a stupid one to an even more stupid one.

You started out trying to claim that it was impossible to shield against the impacts, and demonstrated your total incompetence at physics trying to defend this claim.

Then you shifted to claiming that it was infeasible because we'd have to accelerate the amount of dust that's in the way up to the speed of the craft, as if drag in interstellar space was a major consideration.

There you are again with your "arbitrarily large" mass requirement for shielding, sneaking in an irrational, ignorant implication that the shielding mass requirement would be some infeasibly huge number. I've explained how you might make the shield. There's no reason for it to be a major component of the total system mass. You put an almost arbitrarily small mass of shielding an arbitrary distance out ahead of the main craft (which you can do, because interstellar space).

Sure, but what resources do you need to build and maintain it? After the R&D.

Not to mention energy doesn't eliminate the need for other resources - hell it wouldn't even eliminate the need to drill for oil since we still need petroleum based products (plastics, oils, etc).

Resource and population pressures would be the most direct means of instigating off planet colonization. The Australia or "Moon is a Harsh Mistress" idea of a penal colony that acts as the pioneers - that eventually leads way to an independent colony of its own.

The likely-hood is much higher than zero, much, much higher. Your example using Africa is ludicrous. You forget that there is the rest of the world making steady technological advances. Liquid data storage where a spoonful of the stuff could hold 8TB of data, cybernetics, new medical advances, including potential cures and treatments for both Ebola and HIV. Across all fronts we are advancing. Africa has not advanced, and it cannot set itself to build the required infrastructure, but others have. It is not unified, eventually we will have to come together.

Private concerns are picking up the slack where organizations like NASA are dropping it. We know there is materials in space, we are working to get those materials as a race. We are also looking at efficient energy production, beyond hazardous fossil fuels.

There is also the work that goes into creating new synthetic materials that outmatch most of our naturally found materials. New alloys, etc. To get to where we are at now, it took many years and advances. The rest of humanity used to live like the poor souls trapped in Africa. Yet here you are posting on the internet, in which not very long ago in our lifetimes, geocities was a thing.

As far as economies are concerned, those evolved to. You now order things at the click of a mouse. We might even see the expansion of drone use for mail delivery. Infrastructures require time and innovation to improve. But they do.

By the time we start leaving our system, we may as a race live on a world that is almost alien to what we would know of it today. Technologically and culturally.

I'm not. It just seems that people seem to see space as a necessity and the ultimate solution to the ensuing problems if earth becomes "uninhabitable" when space is always more uninhabitable.

e.g. soil poluted/infertile on Earth -> solution: agriculture in space

Many people just forget that you could do everything to create earthlike environments in space just as well on earth by building isolated domes or greenhouses, while its still cheaper minus all the problems you have from zero gravity, radition protection and risk of decompression.

Space colonization is still cool though. I'd like to have Banks orbitals or huge cylinder colonies. Wouldn't that be awesome? Orbitals at the sun-earth lagrange points?

There's a silly claim if I've ever heard one.

What do we do if there's enough dust or ash in the air that there's no sunlight? How about if the seas boil off, and we get a second Venus? What about a snowball Earth? Supervolcanoes, asteroid strikes, or war could do that.

For that matter, what if Earth becomes occupied by horrible assholes with powerful weapons? There's no environment less habitable than one full of well-armed and hostile humans.

Earth is already more hostile than many locations in space to some of our technology. You can get much more consistent, predictable environments, without Earth's extreme weather or other natural disasters.

I think the africa example isn't quite as ludicrous as you might believe to be but if you feel that way it's fine.

Anyway, you can talk all you want about us advancing our technology at a steady rate but that means little in the end. Op asked what is the likelihood of the pic posted at the start of the thread in 50-100 years. I stated zero because we have no economy suited to support that level of space travel yet in 50-100 years.

Now you may believe we are capable of pulling such a feat in a short amount of time, but all you going to do is find yourself disappointed when the best we can muster is a fleet of space drones to explore the solar system instead of us.

A much better estimate for us is roughly 350 years. In that time at least a dozen countries should have economies able to support space related services on a competent level.

Ah, I made the fatal assumption that you were stating that humanity will never make it to space. I know it isn't really likely to happen in the next 50 to 100 years. Unless of course someone were to make a series of ground breaking advancements.

Depending on what we discover there is at times, a sort of "burst" of rapid progress that can push things forward quite fast. But given the issues on our world, you are right, spaceflight will not happen int he immediate future.

But I still stand by my disdain for using Africa as an example. While divided and seemingly a parody of the greater world, it is still too far behind the times to be relevant.

Furthermore, if Africa could shed it's problems and unite, it could become a powerhouse. It is unlikely that that will happen. Maybe we need one last great war to finally reunite the earth and rise beyond our scattered ruins.

In such a short amount of time, I do believe we will at least start to dabble in Asteroid mining. And maybe even further exploration of the moon.

We have been heading that way for a long time. We will be there in "that" world, way before we go to space. Drone technology can be used for good but will be used for evil. The smallest drones will be able to record high definition footage, while only looking like a mosquito. Some will even be able to assassinate people. Not only that but surveillance technology is getting much better at what it does. Scientists and tinkerers are actually experimenting with cell-phone echo-location systems like that which was seen in the dark knight.

You thought guns were scary? Picture this scenario. You could be sitting at a computer in the night and feel a small sting on your neck. Then a few minutes later, you are paralyzed and dying. You must have pissed someone off somewhere but it's really pointless thinking about that.

It was and it wasn't. The paper refers to both the unslotted device and a resistor as the "null". It's badly written.

>There was a control drive and it did not produce any thrust.
Both the resistor and the unslotted device measured thrust. They believe they understand the former but have not tested it.

>The null drive was for testing if a specific feature of the drive was relevant to the overall operation; turns out it wasn't.
No. Under the understanding of the person who designed this drive it shouldn't have worked at all. EmDrive is dead.

>reputable testing sites in both China and the US
No. This group is not reputable. They in the past also validated an anti-gravity effect, before realising it was an error. The Chinese group didn't spot that the original calculations were bunk, still got the results they expected and now won't answer questions. This is not reputable. They haven't produced any statistics and some of the results have zero repeated trials. This is not a conclusive experiment.

It requires further testing but we should not forget that the NASA result "measured" orders of magnitude less thrust than the Chinese version and the original claim.

I assume your picture depicts a space settlement on another planet? If so, I say, yes, hell yes.

SpaceX is already developing reusable rockets and NASA is prioritising transportation vehicle engineering. In 10-20 years, they could perfect it, and make it possible to transport regular life supplies and materials to sustain settlements on other planets like Mars (easily within an affordable reach.)

10-20 years is also the time it will take us to figure out how to live on other planets permentantly or long-term. I'm saying this because of MarsOne which aims to do this, but also because investigating permentant settlement on other planets will advance virtually every field in science, so it is definitly not going to be overlooked.

After we have transportation and permentant (albeit small and modest) settlement we can figure out how to build a metal refinery on Mars, which could take local resources and make building materials out of them, enabling a proper town to be built there, and to have a real, expanding, human settlement within 50 years.

I participated, and then helped run a competition for under 18 year olds which is run by NASA and involves them designing hypothetical space settlements for large populations (10,000+) on planets such as Mars or the Moon and planning out virtually everything that will be required for them, and the kids come up with great feasable ideas.

Which is why I am confident that there will be a permenant settlement on Mars within our lifetime and to which I will be fucking off to as soon as it opens up.
