It's challenging enough just living in some of Earths inhospitable locations, Liverpool for example.

oxygen and food would be the greatest hurdles, everything else has or could be achieved barring scaling it up in size.

if you could grab an ice asteroid you could get water, hydrogen and oxygen from it for quite a while.
more realistic is growing plants or dissolving minerals to give off oxygen and create food. nuclear and solar power for energy.

There might be potential problems with muscle atrophy in zero-g conditions.

The sheer size of an orbiting space station capable of sustaining that many people for so long would in itself be a massive problem, due to the risk of collisions from all the space junk whizzing around up there. Currently the ISS is constantly being pinged with tiny bits of junk too small to detect/track and regularly has to adjust it's orbit to avoid potentially catastrophic collisions with larger pieces, and obviously the risk of such collisions becomes even greater with a larger station.

This one phall?

''A 982 megahertz signal dubbed BLC1 (Breakthrough Listen 1) came from the star, as spotted by the Parkes telescope in Australia in April and May 2019. Most tantalizingly, the relatively nearby star system contains a planet dubbed Proxima b, which is about 20 percent larger than Earth and located in the systems habitable zone, the area where its theoretically possible for life to sustain itself.''

They got the signal last year!

SETI is saying we should be cautious.. wtf do they know?? Probably jealous they couldn't find it first.

It does make sense.. the closest solar system to us. Maybe they seeded Earth?

These SETI c*nts it doesn't need to be habitable for there to be an alien signal. It could be a beacon! It could be a stray alien probe! It could be any number of things..

It's probably Tazerface.

It could also be a faulty microwave oven in the observatories staff kitchen, like it was the last time the Parkes telescope folk thought they'd found a signal.

Don't believe the hype from Popular Mechanics or the other online magazines. There are so many cube sats wandering around the Solar System to cause spurious signals quite frequently.

Study raises the possibility that our own universe may look like a black hole to outside observers.

So the universe began.. but think of it as a mass of bubbles. One bubble spawns many others that branch off from it.. and so on and so forth ad infinitum.

''What's also fascinating, some of the bigger baby universes might not have gone so quietly. Above a certain critical size, the theory of gravity developed by Albert Einstein permits that such a universe may be perceived differently by observers. If you were inside it, you'd see an expanding universe, while if you were outside, this baby universe would look like a black hole. A conjecture that leads to wondering - are we potentially on the inside or outside of such a universe ourselves?''

From what i have read the big bangs source is not any one point it is everywhere as space is expanding in all directions i dont really pretend to understand it though

Is that astronaut vaping years before its time? Time traveller?

I'm currently reading a book about anti-gravity.

It's impossible to put down.
