It's all pretty incredible, isn't it?

>FTL travel is time travel impossible tier
>What is Alcubierre drive?
Also, time travel into the future is EZ-tier.

Just make the universe smaller instead

we need to make contact

Soon you will wake from suspended animation and begin the Gliese 581c colonization mission . The life you've lived is only a simulation to keep your brain from atrophying during the voyage.

What if I'm perfectly happy being "stuck" on Earth?

It's not like there's much to be seen out there anyway. Nothing that can't be simulated in the near future anyway. Just wait for a VR app. The universe is dead and we're alone.

Also, the time it takes to travel to distant parts of the universe is mostly meaningless if you can be made immortal. And that's not made impossible by laws of physics.

Most likely we will end up sending probes or things on thousand year voyagers to other systems which will build Einstein-Rosen bridges there. A species could colonize a galaxy in under a million years that way without any magical technology, if indeed there is no way to fundamental ly get around the speed of light. A million years is a relatively short period of time on the galactic scale, but think about what an intelligent species could achieve in that time.

Do you even relativity? Just imagine you have enough fuel for 100 years of acceleration (let's just assume) and you accelerate with ~10m/s2 for said 100 years.
Maybe you will not come far in the lifetime of an observer on earth, but I bet you'll come a lot further in your lifetime.

>vast distances in space make interstellar impossible for organic lifeforms
Time slows down for anyone traveling near the speed of light. A thousand light-year journey to a distant star would only take a few years for the traveler.So you see, the problem is not how far things are, but how do we, as a civilization, travel all at once, so nobody get left behind.
Imagine this as a massive fleet of ships traveling all at once, or maybe even a few moon-sized motherships. It's not even that impossible if you think about it.

Preventing smallpox used to be impossible tier. Don't write it off just yet.

>>tfw you figure out we are stuck on earth
We can still travel around the solar system and maybe colonize some shitty planets with automated long range ships. Though that last one would be kinda pointless because we couldn't trade goods with the colonies or send alive population there.

>>8499855
mechanization is the only way

>tfw star trek will be just as unrealistic in the 2260s as it was in the 1960s

If you could accelerate at 1g continuously you can visit the edge of the universe in a surprisingly short amount of subjective time.

Heavier than air flight was once thought to be impossible, along with faster than sound travel.

Relax, and know we will find many new ways to do almost everything as "time" goes on.

>>8499855
Speaking in terms of the laws of relativity, as long as we can reach speeds infinitely close to that of light time won't matter. Of course if you do travel everyone you know will die and everything you know change by the the you come back.
So the question arises will it be worth it? Especially since unless travelling no organisation will get any data from the research.

>>8499945
I double this. I don't give a fuck about teenagers dreaming of alien pussy or vast wealths of distant stars. Forming a nation consisting exclusivly of people with PhD on some planet in solar system is good enough.

>Heavier than air flight was once thought to be impossible, along with faster than sound travel.
That's not a valid fucking comparison you retarded shiteater.
We've always known that heavier than air flight was possible because birds are heavier than air, we just didn't know whether humans would be able to do it.
Supersonic travel was less certain but there was no law of physics telling us that it was impossible.

no cuck
do you even into UFOs
aliens are real, you're just too stupid to understand them

>Alcubierre drive

You do know that the only way for that thing to work is if we use "exotic matter" (read: fucking magic) to cause the effects required.

There weren't any physical laws keeping smallpox from being eradicated

Even if it does work, it kills everyone inside the bubble through shitloads of radiation.

If we ever discover intelligent life, it won't be from our universe. It'll come from another Earth in an alternate reality.

Our universe is simply too huge. Even if FTL technology exists, there's no way to scan it all for intelligent life. And even if you find signs, by the time you get there, even with FTL they may be long gone. Parallel realities has the highest chance of finding intelligent life. We know where to look, so there's no searching. There's no need to travel far because it's right here on the same planet.

If we ever find an earthlike planet we could huck a massive colony ship with a couple thousand people at it at 0.2c using nuclear pulse propulsion.

It doesn't take any breaking of the laws of physics and as a bonus by the time such a monster could be constructed you wouldn't even need to aim for "a second Earth", anything you could describe as "a slightly bigger and warmer Mars" within a >50ly radius could be a worthwhile target.

Make the ship as big and pleasant as possible so a multi generational journey doesn't seem like a punishment, just a tightly knit community.

why would a parallel universe be geolocationally identical to ours? everything that has been said about parallel universes suggests they would exist outside of our own universe, not 'overlapping' it somehow

The entirety of homo sapiens alive today are descended from as few as 2,000 individuals that survived some sort of catastrophe 50,000 years ago.

Perhaps even more remarkably, the 50 million inhabitants of the Precolombian Americas were descended from as few as 70 individuals that crossed the Bering land bridge 16,000 years ago
