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.
Space isn’t really a vacuum
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 it, but we consider it as nothing so we can see space as space.
Vacuum does not only infer an area devoid of matter… it’s also considered a vacuum if it has substantially lower pressure than earth’s atmosphere at sea level.
Hold up. Isn’t space under a lot of pressure to expand, only it’s directed outwards, so we ain’t just feeling it?
No, we don’t yet know why space is expanding. But space has way way waaaaay lower pressure than the earth atmosphere since it’s almost empty. It even keeps sucking away bits of our atmosphere.
I mean, on average space is empty
Did somebody say… laser moon?
