Space, Time,?

Question

It is said that our combined speed through space and time is always precisely equal to the speed of light. Which means that the faster you move through space the slower you move through time; and visa versa. Also, the only thing that isn't affected by time is a moment; because if a moment changes it then becomes another moment. So what I am asking is; what is the best explanation of time and space? And the part it plays in our lives? After all everyone’s "now" is completely different then everyone else’s.

Answer 1

the short answer is:

everything follows a path in spacetime called a geodesic. no matter how spacetime is shaped at any location, everything seems confined to spacetime. locations in spacetime are called events. everything also has its own frame of reference in spacetime. how you would see another's frame of reference depends on your relative motion.

Answer 2

Space is limitless and limited at the same time...Think of it like u think of a circle. Or, if u where walking around on a circular path. There is no real start point or end point on a circular path. If u keep walking long enough, u won't come to an end or border, u will just end up back where u "started." Space is the same way except the "path" is 3-dimensional. I've heard that time acts the same way and that everything that has and ever will happen has already happened a zillion times before. That is, everything is repeating itself. If u think about it, since time and space are interetwined, and space is curved and takes u in a complete circle when u travel far enough across it, and the passage of time seems to create cycles (which is nothing more than the circular/repeated occurrence of a series of two or more events) it seems possible that time might repeat itself in this way....

Even if our moments are different they are still more alike than they are different. Space and time are intertwined and indistinguishable. One can not be seperated from the other. They are two sides to the same coin, which is existence itself, every thing that is, ever was, and will be

Answer 3

Because we are composed of physical time, and the basis of this is electromagnetic energy, space and time are constant. As a spaceship moves through space, it physically changes location in a particular amount of time (the force of gravity changes physical time instead of physical mass). The idea behind this kind of movement is that of kinetic energy contained within a mass, hf = mk. As the speed of a spaceship increases, so, also, does the overall frequency of that craft. At the speed of light it would convert into electromagnetic energy, thus existing within time as having perfect unity.

Your idea about time being "now" is correct. When "present" time is separated from the past and future, all that exists is now, but the "now" you speak of is still directly relatable to the speed of light. So, in that instance we are all relatable by a common value.

Answer 4

Think of time and space as axes on a graph. (y=space, x=time)

If your slope is steeper (i.e. you are moving faster), then you have a longer line segment between intervals of time (i.e. you move slower through time). If it's shallower (i.e. you are moving slower), then you will have a shorter segment between intervals of time (i.e. you are moving faster through time).

So while the temporal distance between moments doesn't change from person to person, the spatial distance between them is shorter for someone moving slower, and vice-versa.

Answer 5

If you can move to the speed of light, you see a difference, if you not, you do not see or feel different.

Answer 6

Spacetime is an integrated reality which make up the perceivable four dimensions

Answer 7

why are there so many questions about the speed of light today?

Answer 8

we can say time as the fourth dimension in space..besides it's three dimension
