Does Space End
Rising up through the atmosphere the air gradually gets thinner.
Does space end. Our space could be a 3d space embedded in a four dimensional space the universe has four dimensions that humans interact with three of space and one of time but this would imply there is an. Prehistoric footprints reveal how ancient men and women divided labor. Where does outer space start. There is plenty of stuff going on in space.
Well our universe does have an edge that is if by our universe you mean the observable universe. The line between space and not space is really determined by our atmosphere. This is the space that is expanding some refer to it as space time for this reason. Thats what makes this a great question because science is all about finding answers to things we dont.
Everything we know about the universe tells us that space is pretty flat but that just means that if space is like a circle it must be a really huge circle so huge that the part of it we can see is just a tiny piece. It seems most likely that either space goes on forever or that it wraps back around on itself like a circle. So when a comet or something goes past the edge of space it creates a new edge. Space probably does go on forever but the truth is we dont know.
Down here on the surface of the planet its thick enough to support life. Radiation is the reason why even deep space is slightly above absolute zero. Time is progressing radiation is passing through. Where does the solar system end.
The speed of light is just that a speed and the universe has only been around for. It all depends on who you ask. But whats beyond the kuiper belt. Outside neptunes orbit is the kuiper belt.
Beyond that is matterless space a true vacum. Space is infinite however we say that space has edges these edges are the furthest bit of matter in a certain direction. We dont know for sure that space never ends.
