So let me get this straight: we produce an extraordinary amount of spacecraft with nuclear thermal propulsion, launch them into LEO using chemical rockets, capture orbital debris and then send both the engines and debris to venus, costing a conservative estimate of tens of millions per launch?

"We ran the numbers"

Yeah sure ya did. Conflating fantasy, wild assumptions with numerical claims is quite honestly laughable.

Your question is stupid. The replies have tried to explain reality to you but you are too stupid to understand it. The problem is you bud. Not the community.

TMK no one ever writes about crater sized habitats, or roofing that giant canyon.

Significantly smaller space based devices would do the job.

The OP's post and additional comments show immunity to reason, but one of countless reasons is the $18,500/kg ($10,000/lb) cost to get a payload to orbit, and the estimated 2 trillion kg of trash, so you are already looking at $185,000,000,000,000,000 ($185 Quadrillion), and that is assuming everything goes perfectly according to plan, not even including collecting all the trash and many other variables. Considering that is already thousands of times more money than currently exists in the world, this first reason already makes it by far the worst idea in human history. To be fair though, even if it was completely free it would still be the worst idea in human history.

But what if I don't want to reach my own?

That's the one. Dumb founded at its scale

This article would probably put a lot of minds at ease. Headlines today made it seem like we're totally screwed.

I think gravity is a key to keep atmospheric gases trapped but Mars' gravity is much wealer and you can't just pump more gasses into thin atmosphere.

Building domes might be the future colony but they would need to build more reusable rockets, maybe they need to find some water for refueling the rockets.

I have wonderd if we start pelting it with oxygen producing fungi or bacteria we could get a head start in touning it into a habitable environment.

Terraform it to what extent? Enough so that humans could sustain themselves there or 100% Earth-like? The former probably wouldn't take a whole lot, but the latter would be near impossible just because of the size of Mars relative to Earth. Though both would equally take a long time.

Idk what tech we're talking about.

theres frozen co2 at the poles, throwing a bomb at them would release some but its pointless

Yeah i might be wrong but it was something about releasing greenhouse gasses it would make mars better ? Idk I’m just rambling.

They are analyzing all of them.

A significantly shorter commute time as well.

You need humans in large groups capable of planning and implementing projects with century and beyond timescales. Right now, we're struggling to plan past this next quarter.

Solar powered electromagnets the size of Rhode island at both poles. The ozone comes after.

Elon is just not as smart as he wants to think he is.

I am guessing here, but for a quisi star to be possible would it not require a primordial black hole at it's center? As opposed to a stellar black hole.

I know that primordial black holes are currently only theoretical we don't truly know if they exist or not.
