I mean, on average space is empty

Space isn’t really a vacuum. There’s plenty of stuff drifting around, just that most of it isn’t all that helpful to our wellbeing.

That’s not how average works
Windex007@lemmy.world 1 month ago
The average cubic meter of space has about 6 protons worth of mass in it.

Which is… 6 more than zero, right?

On average, humans have less than 2 arms & legs
Tommelot@lemmy.world 1 month ago
2 arms and 2 legs is the median, so 4. I doubt the average will be less than 2.
Dont think less than 2 on average is theoretically possible if the median is 4!

Wait what?
Space is a vacuum.
Could argue it’s not a perfect vacuum. We haven’t created a perfect vacuum on Earth but we have come close.
If I have a container and remove all the air inside. I have created a vacuum. Not a perfect one, but a simple vacuum.
If I add rocks to the container. The rocks are now in a vacuum.
Just like space. Space is a vacuum and there is “rocks” in it.

Yeah, but it’s not just “rocks” in space, it’s everything. Or what we consider as such.
If you see light from distant stars, doesn’t it mean there’s radiation from there to here? There’s lots of stuff in space, you just don’t see it as noteworthy.

Space is a vacuum, the other stuff just makes it not a perfect vacuum as a whole.
When you say “space” it is talking about the nothingness.
If you put something in the space it is no longer space but the object you put there
So like the whole outer space isn’t a perfect vacuum. But the parts where it is empty are, the space.

But space isn’t really space because there’s always something in, but we consider it as nothing so we can see space as space.
