Space is a terrible vacuum. It's full of literally everything.

So is my vacuum.

[-] ladicius@lemmy.world 8 points 1 year ago

In that regard Space can no longer be considered to be a vacuum. Not even remotely.

The distance between stuff is so inconceivably huge that it's still a vacuum. Kind of incredible to think about.

[-] SpaceNoodle@lemmy.world 4 points 1 year ago

What are you even talking about? I can see loads of stuff right here.

True vacuum doesn't exist, it's always relative to something else, generally to common human environment.

This is absurdly untrue. Space is VERY empty. The above comment is just plain wrong. CERN has the best vacuum in the world at around 1000 atoms/cc. Deep space is less than 1. Even nebulae have a density far below 1000 atoms/cc, and those are the most dense regions of space.

It may be true that we use vacuum pumps for chip manufacturing that get vacuums less dense than the exosphere, which we like to call space sometimes, but it's definitely influenced by Earth and not a good definition of a space vacuum.

It's a joke, buddy.

If space was a vacuum then Roger Wilco would be out of work.
