the difference between the concept of time and the concept of spaceTIME.

In: 19

Basically Einstein theorized that time isn’t just a flat line, but it’s actually interwoven with our universe, space. When space gets affected by something like mass, creating gravity, time also is affected. Think of space-time as a trampoline, and when you place a heavy mass like a bowling ball on the trampoline, space-time gets deformed. This make things fall toward the ball (gravity) and makes time move slower.

Spacetime is a four dimensional place where the Universe exists. Three of those dimensions are spatial (up/down, left/right, forward/backward) and one of those dimensions is time. It seems that everything is moving at a speed of 1 second per second in this time dimension, but at very high speeds in the other dimensions a limiting condition surfaces. Since it’s easy to transform between the spatial dimensions we’ve discovered that for very large speeds, the transformation also changes speed in the time dimension, slowing down clocks in what is called special relativity.

Because the originally idea was time AND space were 2 different things.

You change space (tracking an object by a few feet) then time (by sec) moves independently with no influence with each other.

Now, turns out for a cosmic speed limit to exist, space and time needs to influence each other to compensate.

Time + space = spacetime. As other people here have explained better than I can, spacetime is a term that connects space and time. Einstein’s theory of general relativity, which has been proven correct (though not complete), connects space and time, showing that time is interconnected with space as if it were a sort of fourth dimension. Warping space warps time and vice versa.

The ‘time’ in spacetime is the same as ‘time’ itself. Spacetime puts space and time together because you can warp space which directly effects the time traveled in that space (relatively).
