Current Events > we have so much junk in our atmosphere that might make space travel impossible.

tl;dw: there are junks the size from satellites to tiny shards, that one day, will form a "cage" around earth. These debris travel very very quickly that each of them are basically a bullet. Our rockets also travel in a very high speed, therefore they can collide, and even a single metal shard can damage rockets and and satellites, basically prohibiting anything launched from the earth.

Lmao humans are so fucked up.

Those guys need to hurry up and finish their series on size.

Its been almost a year. Dang. about black holes too

We can clean that shit up if necessary.
---

cant we vaporize them with lasers, or build tough shielding (or even energy shielding)?

Plastic straws be on some shit.

NASA: Stop polluting the Earth, guys.

Also NASA: Technically we're not polluting the Earth, so...

I, for one, am shocked that mankind has polluted and trashed a natural wonder!

wouldn't there already be all sorts of random tiny things zipping through space at insane speeds? Things that could randomly just rip anything they hit apart?

Weren't you listening? Nintendos pass through everything!

Only an orbital elevator for Gundams can cure this problem.

Yeah we can. Question if we want to.

Toss em into space not working out it seems

just make a big space net

i saw this the other night and the alarmism irritated me

while the cascading destruction theory is a legitimate concern, the idea that we're already on it is not

typical spaceflights do not deposit the majority of their debris in LEO anymore, nor have they for a long time. most lower stages are dropped within the atmosphere, typically only penultimate stages drop in LEO and with spaceX, not even those.

LEO isn't the only orbit we use, just the most common, and a lot of what he's presenting about momentum transfer is ignoring reference frames. a 30,000kph object striking another object that is also moving close to 30,000 kph in a similar direction is not going to obliterate it.

yes

but keep in mind that space is big and it doesn't take too much stuff to be near earth for the concentration to be significantly higher there than most other places

Interesting thanks.

Our planet must look like such a shithole to Aliens that fly by with all the junk swirling around it. It's embarrassing tbh.
