Is Time Affected by Space in the Universe?

[lay-man]

Sorry for the stupid question
I have no phisics education (ie keep it a bit dumbed down), however i just find certain parts of phisics interesting and have a few questions which i have been wondering about.

My understanding at the moment is that mass bends space (why we experience gravity), much like the example of a bowling ball on a trampoline.
However my question is, does time also bend with space or is time a completely separate thing?
Surely if time bends with space then although werever you are a second will always be a second it would be experienced different in another area of the universe (a second here is a minuite there)?
However if time and space are not connected then space bends and time does not meaning more space would fit into the same amount of time meaning it would be experienced differently (a second here is not a second there)?


These are just the thoughts in my head and i assume are am way of the mark so if someone could point me in the right direction it would be appreciated
thanks in advance

Without trying to answer your question directly, relativity theories (both special and general) include a coupling between space and time.

Note the spelling of the word "Physics", as shown many times on this page!

Space and time work together and cannot be separated. The bending analogy of the ball on a rubber surface is actually bending in the time direction. Bending in time reproduces Newton's gravity. Bending space by the Earth is very difficult to measure since it is so small, but see Gravity Probe B.

i do apologise for the spelling error i accept on a physics forum, of all words to be mispelled physics should not be one of them lol (although please forgive further spelling mistakes as they may occur)

however assuming space and time work together and are inseperable as posted above how does this affect time in different areas of space? and why does speed affect time if they are one?

"mispelled" is pretty bad, too. Firefox has a spell checker that automatically shows red wavy lines. I thought all browsers did that now?

My favorite explanation: See http://arxiv.org/abs/physics/0302045"

Equally physics uneducated as you are, but here is my understanding:

There is no "space" without "time", there is "spacetime" - it's really one thing. Wherever you happen to be, you perceive distance and time as consistent, a yard is a yard, a second is a second. Gravity and any other accelerations relative to you can distort how the other object looks and how time flows RELATIVE TO YOU. If a spaceship were to fly by you close to the speed of light, and you looked in it's window, everything would appear sped up as it approached and slowed down as it passed. This is what causes Doppler shift. Interestingly, to the person on the spaceship, they would see the same thing. There is no place in space or flow of time, if you are in it, more relevant or valid than anywhere else. There is spacetime wherever you happen to be, and however fast you are going, and it is your reality, just as valid as anyone else's.

The Doppler shift is one thing (changing latency of getting the signal), and time dilation due to velocity is something else. They both exist, but are not the same thing.
