Which is scary because it suggests that life is of no significance to the uni(multi)verse at all. People think that life only on Earth means it is special - it actually means the opposite. It is like hearing about a sad kid with a deadly disease which no other person is known to have.

You mean that water is essential but beyond that we don't really know much about what other conditions must be present.

I would only support it if trips lasted less than 30 minutes in average. I don’t like commuting that much.
The nearest star to Earth, after the Sun, is around 4 light years, so provided you could travel at the speed of light, it’ll be like 8 years for a round trip, so it will be really boring, I guess.

It is great that there a billion planets just like the Earth that we could inhabit.
Just have to figure out how to travel those vast distances.
One cannot travel faster than the speed of light, so humans are limited to distances of just 100 light years. Which is really nothing in terms of the overall size of the universe...

Many things have to be similar, temperature ranges and atmosphere/ pressure and maybe a lot more.
But i suppose if we can travel that far, then we can fix the atmosphere too.
Solar radiation will be another thing.

We won't be around long enough to figure any of that out. By the time we figure out how to inhabit another world (100+ years), our world will have brought its own demise.

Something just doesn't have to come to life, but it should be able to divide and create another half or child that can carry on. So there is a lot of information that has to be present in the very first living thing otherwise it will just die without any children.
So these basic systems cannot evolve over millions of years. They have to be there to begin with, and can later improve with evolution.
That;s a very tall order if you ask me. Even the tiniest forms of life (and virus too iirc) have DNA information in them and that's a complex structure with amino acids, proteins and stuff.

Nope. in another few hundred years we could be making large ships that can sustain generations. The demist of the earth is a few billion years away. We would have sent many generational ships from earth by then.
They don't have to reach a planet. they can just keep living on the ship forever. In fact, after a couple of generations, the people may be frightened of the idea of being on a planet whereas their ship is safe and provides everything.
This ship would be several miles across, like a city so it will not be claustrophobic. It will be self sustaining unless people screw with the environment or go to war. Or suresh.

We understand how life got created. They teach that at nursery nowadays. But the tough part is how did suresh get created. Even Hawking and Eyenstine cuold not under or overstand.

You honestly think people will not destroy everyone before this happens?
Sentinel

They will.
But i was discussing this from a scientific perspective, not the human angle. Of course we will destroy the planet in a couple hundred years.
But then there is no discussion of the future !

That, and traveling faster than the speed of light are physics constraints that can’t be violated.suresh would be weightless

Not entirely true. The reason you can not travel faster than the speed of light is due to an object becoming infinitely too much mass which means the energy needed to move the object does not exists.
However, if the object that you intend to move (spaceship) has a negative mass, then by the laws of physics it is possible. Since theories suggest there are such particles, it is possible to harness these particles and latch them to an object to reduce mass to zero.
Therefore, traveling at the speed of light could be possible in the future, or somewhere in the universe.

You can always take a nap. Just have the driver wake you up when you get there. If you take a self-driving vehicle there, I would imagine some sort of alarm clock could be built into it.

So folding or warping space-time is no longer an option?

That is not speed, but rather time.

It's been quite a while since I've done any Interstellar traveling. I am assuming that autonomous Interstellar vehicles of the future don't require any such pods. The whole vehicle could be a sleep pod

Regardless. Folding space time is a way to circumvent that speed/time constraint. This is the point I'm making.

But this would defeat the purpose of traveling. You would travel the time, and forever lose time in the process. However, if traveling at the speed of light, you are within the restraints of time.

Well, @Sudacafan better be prepared to never come back. However, I am a nostalgic guy so I prefer the sleep pods to the sleep ship. The technology of those I still don't trust.
There is RNA below DNA in complexity and then there are precursors to RNA.
Most importantly, life may not have been binary. There may have been many little collections of chemicals where autocatalytic reactions were going on, which eventually led to life. It was probably not a dramatic moment and what you think of as children may simply have been molecules produced by autocatalysis.

Are you still getting over the jet lag ? If you ask me that's the worst part of interstellar travel. Once you get used to slimy green aliens checking your passport, that is.

What if someone were travelling the old fashioned way.
And with your 22nd C tech, you folded the space-time between the same source and destination. What would happen to that poor fellow.
Lets say suresh left in a spaceship to SUranus, and while he was midway you folded the spacetime to Suranus or Neptune. Would he get folded/crushed ? Or would there be a huge bump/tear in your spacetime fold ?
What does your supacomputa say?

I've done a fair amount of interstellar traveling. If you've been reading the research, it messes with your circadian rhythms and everyone becomes insomniacs after a while. (You've seen my thread on that recently.) So sleep pods never really worked in the long run. They just resulted in an insomnia epidemic of galactic proportions.

It depends, the particles might not be able to attach to suresh due to various reasons...
Yeah, I heard the new in thing is to just not sleep. Sleep is for pansies.
