It’s already outside. Voyager

I doubt our chances for getting out of the 21st century. Or for some of us to get into it.

We'll never make it. We've already started sliding backwards in science. We have a majority in political office who don't believe in basic scientific discoveries like evolution and man made climate change. Some of them actually believe the earth was "created" in 6 days. I don't know if we can come back from this.

I don't know about anyone else, but I'm not going anywhere.

I honestly don't know what our chances are. There are some serious technological, and biological, challenges to overcome for that to become a reality.

The distance to the edge of the observable universe is about 46 billion light years because the universe is expanding all of the time. So how big is our universe? Well we don't really know, but it's big. So big that even light hasn't had time to cross it in nearly 14 billion years! And it's still getting bigger all of the time.

Damned small chance.

If we survive as a species, we'll do it eventually.

it's hard enough getting people out of there own little bubble

It's funny but we actually need warp speed (like on Star Trek ) to accomplish that. Who knows it may be possible.

Zero... unless one of those aliens show us how.

Humans are like a virus. We multiply, spread, kill, rape/steal, and repeat. I have no doubt we will leave our star and do what we ‘do best’ on other planets.

They way things are now politilly and socially, probaby not within our lifetime. I don't think we'll even try. I'd LOVE to be proven wrong.

Unlikely if ever. Given that we have a 95% chance of being wiped out within the next millennial

I think exploration outside our solar system by live humans to be low-likelihood. Unless incredible propulsion & BRAKING achievements are developed, any such mission would be an effective Kamikaze Mission (never coming back) for the crew, which would limit mission approval.

That kamikaze aspect could be embraced in a more "sending out a colonization force" level mission, but the material and wealth required to send such a contingent to such distances purely on a speculative no-chance-of-return mission ... again, there're huge hurdles of feasibility, finding capable & willing people, and getting society & governmental approval.

If we get a millennium of pre-supernova warning for the solar demise, that might be enough time to dedicate enough resources into a proper "colonization" (read: "lifeboat" ) effort.

I lean optimistic. I think the odds are good I just don't know about the time frame. I also am torn between whether we will first depart in a generational ship or a seed ship. I think seed ships may have more potential for rapid expansion.

If we survive the impending crisis of global warming, disappearing agricultural soils, chemical contamination, lack of potable water, risk of pandemics, and interspecies strife we might get our machines beyond the confines of this little star system, but, the odds are against us.

Not in our lifetime.

If we manage to survive ourselves for another century, I'd say our chances of venturing beyond the heliopause with a manned mission are pretty good, providing we find promising signs from the Centauri system. That is within our reach with perfected VASIMR technology, and we're close to that now. Maybe another 10 to 20 years. When that happens, Mars is about 40 days away.

If we find a way to produce antimatter more efficiently than we can now, then near relativistic speeds are within reach and it is conceivable that the Centauri system would be a 15 to 20 year ride.

Too early to tell, we’re still in our infancy in that regard … though moving a lot faster than the days of Magellan.. But if we can’t break the barrier of lightspeed ..what’s the point?

No, I'm going to make the argument that we don't know how big the universe is. We can see 13.8 billion light years, but until we develop the technology to travel beyond our corner of the universe, we will never really know how big and how many layers of what we exist in?
And age?
