Any theories about that? If humans would actually be able to build up colonies in the Moon etc in the next two decades??

Well we know is would take 1yr and 3-4months to reach Mars.
And that out first Venture there would not result in a return trip.
But on top of all of that I totally believe we can survives the first trip and can provide for further trips.

But do i think it will happen in the next 20yrs, No. More like in the period of the 2060s to 2080s.

Might want to actually get to the moon first, not fake it like last time.

I’d go to Mars, even if it meant giving up everything here. What’s to lose, really?

I would go to Mars if it possible. It may cost a lot of money tho

We will have the technical capacity, but it won't be worth the risk and expense

Lmao, no, humans won't be able to set up colonies on neither the moon or Mars for at least 50 years, we won't be ready on a technical, physical, or mature level for a good while. And honestly, it doesn't seem like very many people are excited about the prospect.

Most billionares are throwing their hat in the ring to get that going so i dont see why we wouldnt start building space colonies in the next 20 years

If you had told someone in 1969 that in the next 50 years humans won't even go back to the moon or anywhere, they'd think you were incredibly wrong. We can't really say anymore unless there's a drive to go to the moon or anywhere like the 60's

I don't see this happening at all. Maybe in the 2100s.
