The basic idea behind “warping” space or time comes from Einstein’s General theory of Relativity… What he proposed was a totally new, geometrical description of space and time that led to a different description of gravity—one that linked space to time and mass to energy in a fundamentally geometrical fashion. In other words, mass(-energy) shapes space(-time) instead of acting like a “force” in the traditional Newtonian sense. This alteration in the fundamental geometry of space-time is often described as the “curvature” or “bending” of space. \n\n(Thus, in Newton’s description of gravity, one would say that all bodies exert an attractive gravitational force on one another; “space” is just the place where it happens. In Einstein’s conception, one would say that all bodies change the underlying geometry of space—and time, too—in a way that causes them to be attracted to one another.)\n\nSo we often talk of space-time being “warped” or “curved” by the presence of mass(-energy). The only we see space-time deformed in the Universe around us is by the presence of a lot of matter—light being bent around the Sun, clocks being affected by Earth’s gravity, that sort of thing. \n\nThe caveat is that curvature or bending really only provides an analogy to what the equations tell us. If you want to imagine the effects of an object on its surrounding space(-time), then you can think of it as changing the shape of space(-time) in its vicinity. The distortion is real—we can measure its effects—but the images that are often presented (of flexible sheets of space-time with bowling balls or marbles rolling around on them) simply present analogous situations.\n\n\nRyan Wyatt\nRose Center for Earth & Space\nNew York, New York

a speeding object slows down in time due to gravity not speed. that's why steins general theory was also trying to tell us. that gravity slows time.

there is friction in space as said before but it is also because there is matter in space, just not very much, and eventually it would cause the object to stpo spinning

The basic idea behind “folding” space or time comes from Einstein’s General theory of Relativity, so if you’ll bear with me for a moment…  What he proposed was a totally new, geometrical description of space and time that led to a different description of gravity—one that linked space to time and mass to energy in a fundamentally geometrical fashion. In other words, mass(-energy) shapes space(-time) instead of acting like a “force” in the traditional Newtownian sense. This alteration in the fundamental geometry of space-time is often described as the “curvature” or “bending” of space. \n\n(Thus, in Newton’s description of gravity, one would say that all bodies exert an attractive gravitational force on one another; “space” is just the place where it happens. In Einstein’s conception, one would say that all bodies change the underlying geometry of space—and time, too—in a way that causes them to be attracted to one another.)\n\nSo we often talk of space-time being “warped” or “curved” (honestly, “folded” sounds a little extreme) by the presence of mass(-energy). The only we see space-time deformed in the Universe around us is by the presence of a lot of matter—light being bent around the Sun, clocks being affected by Earth’s gravity, that sort of thing.  To do something similar (like the “Smallville” example) would require very large quantities of mass or energy.\n\nThe caveat is that curvature or bending really only provides an analogy to what the equations tell us. If you want to imagine the effects of an object on its surrouning space(-time), then you can think of it as changing the shape of space(-time) in its vicinity. The distortion is real—we can measure its effects—but the images that are often presented (of flexible sheets of space-time with bowling balls or marbles rolling around on them) simply present analogous situations.\n\nThe issue with “folding” is that it suggests something like a crease in space-time, and that’s problematic in the sense that gentle “curves” or “warps” are mathematically simple to describe, but adding anything like a hard edge becomes tricky.  Plus, to make the transition from one part of space-time to another requires bringing those two points in contact—a challenge that makes “folding” look simple!\n\nJ.

Imagine that the earth suddenly disappeared.  Would the moon fly off into space immediately or would it "wait" until the gravity from earth "disappeared" at some short time later?  We know that nothing goes faster than the speed of light, 3*10^8 meters per second.  So, what is the speed of gravity?\n\nThe answer, according to Einstein's General Theory of Relativity, is that gravity does not really exist.  Heavy objects warp the space-time around them.  A common analogy is to imagine that four of your friends are pulling on the corners of a sheet.  Place some tennis balls on the sheet.  Now place a bowling ball on the sheet.  The tennis balls go to the bowling ball, not because of "gravity" of the bowling ball, but because the sheet has been warped by the bowling ball.\n\nThus, according to Einstein, if the earth were to disappear, nearby space-time would cease to be warped and the moon would fly off immediately.  This is how Einstein solved the paradox that the speed of gravity appears to be faster than that of light.

yes, space-time gets warped/bent with mass.  This has been used to try and explain gravity somewhat, but with objects like planets, it doesn't happen that much.  The 'strings' from string theory and black holes bend space-time considerably.  black holes are basically singularities the size of a baseball that are as heavy as a planet or star... that's how dense they are.  It's basically so dense that it's just protons and neutrons smashed together, and considering that most of atoms are usually empty space, this is very very tightly packed, which is why there's so much gravity and the escape velocity to get out of a black hole is so great that even light isn't fast enough to get out.  Cosmic strings (the ones froms string theory) are also this dense and they are also said to bend space-time around themselves.  If you're interested in this, I would read "The Elegent Universe" by Brian Greene.  It will explain it a lot better than I can here.

The previous answer described gravity in the Newtonian sense, but Einstein had a very different explanation. He said that massive objects cause space to warp (like placing a bowling ball on a trampoline). Massive objects are "attracted" to other massive objects because they fall into these gravity wells. Thus, there is no energy conversion, only a tendancy for objects to follow the path of least resistance through space (as when you place a marble on the edge of the trampoline and it "falls" inward toward the bowling ball).

the theories of time travel are extremely complex. it is often mistaken that one can use radiation or electro-magnetics to warp space into  an alternate reality. one of the popular theories of time travel is only from a certain point. what I'm saying is that we will not be able to visit this time from the future. \n\na few theories are;\n\n1: warping the very fabric of space, then accelerating to near the speed of light through the folds. the speed would then turn you body into pure energy, eventually reformulating somewhere in the future. Problems: 1; to warp space fabric would require more energy than it takes to make a black hole. 2; this is my personal theory.\n\n2: do you know how a worm-hole works? if not, ignore this section. but take an opening of a worm-hole and some how place by a point of high gravity (a neutron star). while at the same time directing negative energy at both openings in order to keep them from collapsing into a black hole. time slows down in super-high gravity, therefore if you throw yourself into the opening with no gravity, you'll wind up in the past. and vise-versa. Problems; 1; worm-hole technology is beyond our reach at this time. 2; worm-holes are flickering in and out of existence every infinitely small spec of time, therefore it is difficult to isolate one.\n\nas for what time travel exactly is, i could go one for about three pages.\n\nI'm a nerd. \n\nStargazer.

Fun stuff, this gravity question. One of the leading hypotheses of the past was that the expansion of the universe would eventually slow, and gravity would then pull all mass back together, resulting in another singularity, and a recurrence of the big bang. \n\nRecent evidence says that this isn't happening. Instead, as the universe expands, the gravitational pull will approach zero. The consequence of this new hypothesis is that the universe will eventually spread itself into nothingness, and as the stars fade and run out of fuel, the universe itself will fade away into cold and darkness. Not that it's something we have to worry about anytime soon.

They are moving tangentially to their orbital path at a speed that doesn't change.  At the same time, the Sun warps space like a bowling ball on a stretched rubber sheet.  They keep trying to fall into the Sun but they move sideways just fast enough to keep missing it by the radius of their orbit.\n\nIn addition to warping space, the mass of the sun also slows down time, but that's another matter.

General Theory of Relativity:\n\nA mass in space creates an indention much like a bowling ball on a trampoline.  Its this indention that is the cause of gravity.  If a marble were to roll across the trampoline into that indention, it would take a curve path and eventually fall into the bowling ball.  This is what happens when you fall to the Earth: your body is in a sense sliding on the curvature of space-time.

I read a book about this.  I don't remember the title, but this guy claimed he had it.  He claimed that all atoms are expanding at the same rate.  This is what causes gravity.  More massive objects expand in more space in less time than less massive objects.  \n\nI don't remember the details of the rest of the fields, but they all related to this expansion of atoms.

You're right, it is due to the speed they are traveling.  Velocity distorts time by the factor: t'=t/sqrt(1-v^2/c^2) where t' is the time that passes for a stationary observer, t is the time that passes for the object moving at the high velocities, c is the speed of light, and v is the velocity the object is moving.  \n\nThis effect is basically negligable unless the object is moving close to the speed of light, but the orbiting satellite is moving pretty fast for a very long time, and so even though it's traveling at a very small velocity relative to the speed of light, it still builds up a little and creates a small distortion of time that is barely noticeable.  For example, let's say the satellite is traveling at 8,000 m/s for 5 years.  if you do the math, there are 157680000 seconds in 5 years.  The speed of light is 299792458m/s.  Now lets see how much this effects time.   That number will be t', since it's how much time passes on earth for 5 years.  Now let's see about on the satellite:\n157680000=t/sqrt(1-(8000^2/299792458^2)  solving for t, (must have fancy calculator with a LOT of places) we get t= 157679999.88772s  subtracting this from the original time, the clock is behind by .11228 of a second.  \n\nTime moved slower for the satellite, but since the velocity is so small compared to the speed of light, the amount that is different is so insignificant, that you wouldn't be able to see the difference through a telescope.  However, they want the clocks to be perfectly calibrated and exact, so they do that to make up for this small effect because it would build up more and more as time went on, and the faster the satellite is moving, the more time is distorted.

How is time effected by very strong gravitational forces? For an observer not caught up in the massive gravitational forces of a black hole, but able to see an object moving in a space that is effected by a super massive gravitational field of a black hole, and for instance an object is moving at 100 Mph trough 100 cubic miles of space in the strong gravitational force field where the 100 cubic mile of space is compressed into 10 cubic feet the object would move through that space with 10 feet per hour or less speed, because time along with space is also effected by the massive gravitational field near a black hole. The passage of time is "stretched out" or "slowed" near very large fields of gravitational forces... And near weak gravitational forces the passage of time "hastens" or "quickens". So where the universe is still expanding, ever so slightly, from the big bang, the passage of time is still slightly "quickening" until the universe stops expanding and then may reach a constant size where time will neither "quicken" nor "slow" but will remain at a constant.

Okay. Everything that has mass has gravity. You and I have our own innate gravity. So does your pencil, your computer, the air you breathe. \n\nIf you think of space-time (see Einstein) as the surface of a huge trampoline on which everything sits, then mass sits on top of that trampoline. But if you put a bowling ball on a trampoline, it puckers the surface and smaller things are drawn towards it, and it is drawn towards the smaller thing, if only a little bit. Similarly, if you roll a marble around the bowling ball, it will circle many times before it finally crashes into the bowling ball. (That how orbiting works.)\n\nThis is simplified, of course, but it helps to understand the concepts. If you are interested in the subject, I would recommend reading Billions and Billions by Carl Sagan.\n\nGood Luck!
