Ask Dr. Science
March 27, 2005:
A Spoon asks: In conjunction with space time, is it possible to have an area of space that has faster/slower time than another area travelling at the same speed???
Dr. Science responds:
First off, Happy Easter to everyone who celebrates it. Dr. S here, replying to this weeks email with chocolate bunny in hand. And now, without further adieu, on to the question...
First of all I would like to make a point about the question. Even if "areas" of space do travel, there is no reference point that we could use to measure that movement as shown by Einstein. Therefore I will assume that the question is "In conjunction with space time, is it possible to have a point of space that has faster/slower time than another point of space???".
The answer to that question is yes. Gravity creates a warp or curvature of spacetime; whether it is a star, a planet, or a black hole. This tells us that a point in space that is nowhere near a large mass will have a different "time speed" than a point inside of a black hole persay.
Get it? Got it? Good. Till next week, this is Dr. S signing off.
