How much of an impact on gravity would be caused once we start mining large amounts of material from the solar system back to earth?

I always wonder how much they could add or subtract from the moon's mass before it starts fucking up the tides

>> No.11623601

I have wondered about this every time I hear people talk about how much material is out there for us to use. It seem like people don't think about the long term impact.

you don't think about the long term impact of spending your time wondering about what happens if outlandish sci-fi scenarios come true.

I'm pretty sure that space mining isn't sci-fi.

String theory solves space mining.

The moons massive enough we could mine a shit ton of it before any issues started popping up, and really we could replace any mass we take by setting up a landfill on the dark side or something.
But asteroid mining wouldn't have any long term impact and theyre far richer in mental.

do you think it would make more sense to tug smaller asteroids to a central processing location large enough to conduct most repairs in house?

So naive

I think you've failed to consider just how massive the Earth is. Even adding the entire mass of the Moon is only an increase of ~1%. Every year the Earth loses 55,000,000kg naturally (net effect from losing atmosphere and gaining meteorites).

Any effect on gravity just isn't going to be noticeable

>> No.11626057

>>11625955
Maybe small ones, but I think we are a long way away from that capability. Rock crushing requires a huge amount of energy. Start with how to get MegaWatts of power on a planet first.

None. The Earth is fucking massive.

Most people don't know about the secret Nazi moon base. No reason to ridicule them about something they were never taught.

Venus is a naturally easier mining destination after all.

I just hope the US and China can share it

If we mined 0.00001 grams periodically, it will decrease the gravity.
