Potentially habitable worlds may be much more common than we thought

Well that is exciting.  Now all we need to do is get the various militaries of the world to admit they are hiding crashed UFOs, and we can retroengineer them and go and see these worlds.

Only way for life of earth to survive is going elsewhere with it. The sun will vaporize life on earth anyway.

But where is the evidence?  As a rational, atheistic skeptic, if something isn't tag teaming my wife on the couch when I get home early, it simply doesn't exist.

For a rational skeptic that's a very irrational and anti-sientific post (and speaking as a fellow athiest, athiesm or otherwise, has no relevence here). The phrase used is "potentially habitable", not "inhabited". The hypotheis is based on evidence gathered by spacecraft exploring the moons of our solar system.

Scientists now believe that there are 100 times as many habitable worlds in our galaxy than previously thought.


Yes, they do tell us that but they neglect (here) to tell us that they previously thought, doh! lol - here's a link
there could be as many as 300 million potentially habitable planets in our galaxy

So it appears that that figure will now jump to 30 billion. that's impressive.

If you worry about when the sun will die, never fear: that moment is billions of years away.

The sun gives energy to life on Earth, and without this star, we wouldn't be here. But even stars have limited lifetimes, and someday our sun will die.
You don't need to worry about this solar death anytime soon, though. Like all stars, a churning fusion engine fuels the sun, and it still has a lot of fuel left — about 5 billion years' worth.

Err... Our sun won't do that for billions of years. Billions.  Not centuries.  Not millennia.

And? How mutch time we have left to get out of here before civilization and our species collapse on earth ?

The window of getting out of earth is quite small, we miss it, it's over and I don't think that we will leave something after us that will be able to climb out the ladder and getting the hell out of here before it's too late.

Yeah, it's mostly what people say and they wait until it's too late... mostly 1 billion before anything is sanitize. Yeah it's quite long for our puny existence but the window of a technological advanced species is narrow and life on earth will not have a second chance.

Subsurface oceans, yes, we have such worlds even in our solar system, like Europa. I guess life could develop there but I hardly think intelligent life could develop under water.

We could fix global warming tomorrow. Ask me how in a private message if you are seriously interested.  We have the technology but not the political will, for reasons that elude me.  As to species and civilization collapse, I find that highly unlikely.  I think we will find a way.  There was a time when much of our industry ran on whale blubber, and cars were seen as reducing urban pollution due to all the horse dung clogging every street and gutter.  Before that people literally chucked their sewerage out the upper window for centuries.  Every day in every way we are getting better and better.

Many ways, surely.  Every way, ehhhh.

Cephalopods are an example it can.

Nope it is utterly do-able with one easy fix that nobody is doing.

Yes, but how advanced can life under water become, can it develop an advanced space-faring civilization, even though the surface is hostile, like on Europa? I've read somewhere that fire is crucial in creating an advanced civilization, and you can't have that under water.

I would think the more sophisticated propulsion devices under water became the more advanced an underworld society would be.  Fire under water?  Why would a civilization not 'experiencing' the atmosphere of 'fire necessity' need fire?
