We will never travel more than a few light years away from the earth.

No matter how advanced the human society gets, we will always be limited by the speed of light and relatively short (>1000 year) lifespans.

How does it feel knowing we are trapped in a small bubble?

If you virtualize your brain and pack enough energy to keep it running in hibernation mode you can go most distances.

We could still colonize the entire galaxy in a few million years even at sub-light speeds you colossal faggot. The Milky Way is only 100,000 light years in diameter. Also wormholes and Alcubierre drives are a possibility.

Alright yeah now you only have to acclerate the mass of 2 planetes, we can do that [/sarcasm]
Look dimwit, i hate to break it to you, but its very unlikly we will ever leave our solar system. Do you know why we didnt set foot on the moon again? Or why we havent visited mars yet? Because costs a lot of money, anon. So why would just sent someone even further away?

But okay, lets pretend that money isnt a problem here. So we sent out of an spaceship and all it needs to do is to survive, for what 200 years? 300?
With the only ressources to maintain themselves on the ship. Everything needs to be stored on the ship, with enough supply for a 200year journey and to start up a colony. Yeah right, but we totally colonise the milky way.

Good luck trying to sustain a spaceship for 100 years. Robots and repairs will need a whole lotta ressources and energy. Also 100 years is quite optimistic.

YOU will never get a significant distance away.
WE (humanity) might.
A few percent of lightspeed (not enough for appreciable Relativistic effects) is possible. A few decades for each Jump, then colonizing a world or building O'Neil habitats in the target system. Finally, constructing starships and advancing another increment.

Take a few million years to fill the galaxy, but there's plenty of time.
We could do it, if sufficiently motivated. That's why Fermi wondered why no one else seems to have attempted it.

[Anonymous No.9686049]

>>9686044
We could build generation ships that never slow down or stop.
And just colonize anywhere we can.
Any surviving colonies would have to figure out how to communicate with each other.

You dont even need to approach light speed. Just slowly hopping from one interstellar rock to another is enough to colonize the entire galaxy in a ten million years.

The nearest star, Alpha Centauri, is about 4.5 light years away.

If we travel at 1% the speed of light (which is highly optimistic) thats still a 400 year journey. How would humans with such short lifespans even hope to cross the milky way?

[Anonymous No.9686305]

Stop being pathetic cucks letting "scientists" indoctrinate you about what the "universe" is.

Truth is the earth is an infinite plane, which is why they've got you pondering pointless shit about a metaphysical reality that doesn't actually exist.

[Anonymous No.9686307]

>>9686270
With deuterium-tritium fusion rockets we could reach 10% of lightspeed (and stop again) with a mass ratio of just over 10.
That's not impossible, though no one is denying formidable engineering problems.

45 years isn't forever. People work that long.
It would take a major commitment, both on the part of society (to fund the project) and on the part of the people willing to go.

First of all, you’re proposing 2 different mutually exclusive claims: that humans will NEVER get more than a few light years beyond Earth, and then go on to suggest that humans as a species might, but individuals will not.
Which are you advocating?

I’ll assume you’re talking about the latter. It’s possible that humans, within one lifespan, could see the farthest reaches of the galaxy (not likely beyond that) if cryogenic sleep becomes viable in the future. Additionally, if we are able to store our consciousness in advanced computers one day, this will also extend our lifespans long enough to see many places.
I’m ignoring FTL, as it’s too speculative to consider at the moment.

If none of these are viable options in the future, then you’re correct - human individuals will likely never live long enough to travel more than a short distance from Earth.
But humans AS A SPECIES will likely populate many areas throughout the galaxy. True, individuals will die before they get to the intended destination, but that doesn’t mean the mission dies with the individuals who set out in the first place.
The continued survival and evolution of a species cares very little for individuals. If we decide that it’s in our benefit to colonize worlds far from Earth, we may likely sacrifice the lives of individuals if it means that their ancestors will succeed.

Nah man in about 500 years we should have the science to break the speed of light and get to other stars, you underestimate scientific advancement.

We may explore the entire galaxy and even the entire local group but we'll never explore more than 0.00000000001% of the observable universe because everything else is moving away from us constantly at speeds we'll never attain.

It feels bad but at this point all I want is for us to find proof of extraterrestrial life, I'd be happy with that. I don't doubt there life everywhere in the universe I just want everyone to be aware of it.

Also I'd say that it's the same for everyone, every civilisation, even very advanced ones, are stuck in their small bubble. For some of them maybe they're alone in theirs. For us, we don't know yet.

this is blatantly false, the Laiankea alone is 500 million light years across (0.2% of observable universe diameter) and it's not going anywhere and there are a lot more superclusters hanging around which are not going anywhere

Should be possible in ~100 years, definitely 1000.
