It has been postulated that space curves,but how can you curve Time in the Universe?

Answer 1

It has also been postulated that when you are lost in the woods you will walk around in circles for ever and never
find or reach the way out.

Time is not an entity that you can hold in your hand and twist or bend like a thin shaft of steel, or wood. Time is an incremental measurement from one event to another in a straight line, not a wrinkled or curvy one. Bending would elongate time unnecessarily and violate the definition of time itself.

There are so many theories out there that I wouldn't really spend a lot of time worrying about which one is correct.

The size of space is humoungous beyond your wildest belief. The latest dimension recorded by several astute astronomers was 40 Billion Light Years in every direction from us here on Earth...the "seeable" distance. That means that with the present generation of optical and radio telescopes we can "see" out to a distance of 40 Billion Light Years. Beyond that, our equipment fails to yield any useable information to us. Outer space does not end there, we just cannot see any farther into it than that.

So, now, you are going to suggest that it is shaped like a Pretzel, a Unicorn's Horn, or a Banana?

Once we learn how vast space is, it is not essential to know the particular shape of it. At least I don't think that it is.

Furthermore, nobody is going to travel out there and confirm or deny a particular shape or intricate design or convolution theory. If, perchance they do do that, none of us will be alive to hear about it, anyway. Any radio signal sent out there and its reply would take more than 80 Billion Years to reach our listening equipment, so that thought is sort of worthless also. The normal life expectancy of humans is somewhere on the order of 100 years, not billions of years. So we will all be dead and gone were anything like that to ever occur.

So help us out here... Please try and understand that it is not really possible to know the shape of a whale's stomach and intestines when looking from inside of the the whale's stomach. Same deal with outer space...

Good luck and good hunting,
Zah

Answer 2

Einstein incorporated 'time' with 'space.' That's not saying that time is a *natural* feature of the universe but it must be considered when dealing with space because it takes time to go from some point in space to another. Einstein also showed that the 'fabric' of space is distorted by the presence of mass, therefore it follows that time must also curve. For example, imagine two points in space between which there is no mass (..gravity..) and the distance is 100 miles. At 100 mph it would take 100 hours to traverse the distance between the points. Now stick in some mass. Gravity curves the space between the points, effectively increasing the distance to maybe 200 miles. Now it's going to take 200 hours to move between the points. Space and time (..space-time..) were distorted by the presence of mass.

Answer 3

In a real sense, time "curves" by having it's flow interrupted. Just as gravity curves space, it also "curves" time - the closer you are to a gravitational source, the slower it flows. For a person 'standing' on a black hole, if he were to look up, he'd see the whole universe age & die in what would seem to him to be only a few moments.

Answer 4

No way to "curve" time.
