This article is poorly written.

The main reason it's taken so long to get back to the moon is there's no point going to the moon for a photo op.

NASA realized when we go back it should be to stay.

Why the Artemis missions are focused on figuring out how to set up permanent presence both on the moon and the Lunar Gateway.

We need water on the moon, for water mainly. And for Hydrogen.

What the moon truly offers though is long term and that's manufacturing, refining, and mining. Off of Earth.

We aren't launching any mega structure from Earth ever. No matter how good rockets get.

From the moon... Yes we can build mega structures.

SLS program is already done they are only building the current rockets. Starship will be the rocket used for future programs.

Checking the wiki page on it.

There is a probe scheduled to launch this year that should reach it in 2029.

So we'll eventually have much more details on it.

Hypothetically say China and U.S. do even a tit for tat exchange and take out one of each other's satellites with an ASAT.

Given how much more we have in space these days I don't think it would take much at all to kick off Kessler Syndrome.

In the event of WWIII I think it's safe to assume that the space aspect of the war will be short lived. As it's all going to be shredded.

Hey OP question have you watched Isaac Arthur's video on power satellites?

I don't remember how much detail the video goes into, but there's links in the description for more reading and sources usually

Personally I think we will do some power satellites for Earth, but I doubt it becoming a major power component. My view is based on a lot of assumptions about the future though.

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.

Oh simple solution to not frying Earth with the energy.

Don't send it to Earth.

Most our industry and population will be living off world anyways.

A Dyson swarm, what the Dyson sphere original concept was.

Has none of these downsides. You get usable living space and energy production with each habitat, power satellite you build and you build it as much as you want/ have resources for.

I'm not knowledgeable enough on this subject to have an informed opinion. But couldn't quantum entanglement allow one to technically transmit information instantly?

I say technically since you'd need to physically transport one part of the pair. So you couldn't break causality with it.

My mind agrees, but my back says it's a big deal.

In order to see it we'd need to know exactly where to look. In order to know where to look we need to see it.

If the orbit is eccentric enough then when it's closest to the sun it will be much easier to spot. But that could be centuries from now.

With deep space radio telescopes I think we'd have a good chance of finding any missing planets, could use active radar to scan large sections of the sky.

That also could take centuries though.

This is why there are no diving signs.
