i have read about this insane concept called time dilation.i read that time actually slows down in the space near a massive object like planets and suns, for instance, if you orbit a black whole at just the right distance from it so that you get dont sucked in, the gravity would be so strong that time itself slows down a considerable amount.pretty much saying that we can time travel to the future by using black holes.
how does time slow down?
is time literally woven into the fabric of space?
does the gravity of the black hole warp space so much that the space itself stretches causing us to experience time differently?
i have read that einstein has proved that all matter is energy, he also states that the faster an object moves, the more energy/mass it gains.
so if we combine these two facts, this means that we can time travel into the future by simply moving at extremely high speeds, right?
it kinda makes sense to me because if the mass of a black whole can distort time, then an object moving fast enough to equal the energy of the black whole would induce the same effect right? from my perspective, if every thing is energy, and mass gains energy the faster it moves, then i think its safe to assume that a object can move fast enough to make its energy equal to a larger mass/energy, right?
its like everything is the same thing, kinda.
so simply put, for example ONLY, if we shoot a marble into space at speeds great enough, then its possible for that marble to achieve speeds that gives its mass/energy thats equal or greater then our planets mass right? so in all, the marble would effect the space around it just like our planet does, right?
dang, these are some dope concepts to imagine and understand o.0

Space and time are interwoven into spacetime. Mass distorts spacetime and this is causes what we feel as gravity. Moving through space also changes the 'distance' we move through time and space when compared to someone moving relative to us. Sorry, this is a very simplistic one liner and you will need to read up on relativity to get a full picture.

As above, spacetime is distorted.
i have read that einstein has proved that all matter is energy,
No, he showed there is an equivalence between inertial mass and energy. Sorry, again the explanation is somewhat technical and not easy to explain unless you have read some of the basics of relativity.
Do keep up your quest to learn and when you have read more do come back with specific questions on points you don't quite grasp - we've all been there so you'll find folks here very helpful.

thanks! and yeah, your answers are pretty much what i was thinking.
about the energy equivalent, i stated a example of the point i was trying to make, about if a marble reached a great enough speed that its energy equivalent could match earths mass, then that marble would effect space just as earth does, pretty much saying that an objects mass is increased the faster it moves, thus, there would be no difference between a planet and a marble if that marble were to travel at great enough speeds to match the energy/mass of the planet.
will take your advice though, i will continue to read about this type of stuff, its very interesting.
by the way, is it just me or does everything seem to be connected in someway, i mean, its almost as if everything in the universe can be explained and understood by a single simple concept. what that concept is, i have no clue, i just have a feeling that this is the case.

I am very much a "bottom feeder" in this area ,but I think you are right about your marble.
It would be equivalent to a very ,very ,very......................................elongated planet though ;)
Both mass and energy can be considered to "curve spacetime" ("curve the mathematical model" is how I have heard it described.)
-
i agree, next question is, if that marble with the equivalent of earth were pass by earth extremely, extremely close, what the hell would happen? would it be the same as if another earth passed by us, would the marbles gravity be increased so much that it literally throws our planet into chaos?
also, how much mass do you think it would take to build a giant ball in space with enough mass to distort space to a point where time slows to a crawl, thus giving us a giant time machine near our planet lol.
also, isnt there a way we can artificially induce the effects of gravity on the space around it?
i mean, gravity is something that is natural, so humans should be able to recreate it, if we can achieve this, we could in theory distort space to a point where time is extremely slowed so we can time travel to the future,,,in a way.

The problem is that you are treating speed as an absolute. In Relativity, this is not the case. In order to say that something has a given speed, you have to give the reference that it is being measured Relative to. So with your marble, you would have to say that the marble is traveling at some near light speed relative to the reference frame that the Earth is at rest with respect to. But that is not the only valid reference frame. There is also the reference frame that the marble is at rest with respect to. Form this frame, it is the Earth that is flying by at near light speeds and and has had its apparent mass multiplied by many many times.
The same type of thing happens with time dilation. If you have two clocks traveling at a high speed relative to each other, according to clock A, clock B runs slow, and according to clock B it is clock A that runs slow.
Relativity is not one of those subjects that can be explained properly in a few choice paragraphs. At least not without simplifying things to the point where a lot of important concepts are left not properly explained.

i understand what your saying, i believe i did have this same understanding you have of relativity, how ever, the whole marble example i thought of is only used for a example, when i gave this example, i meant for the perspective to be relative to the marble from earth.so yes, i agree that a object in motion needs to have something relative to compare to in order for it to be considered being in motion, from what i understand, if we pretend there is a ball inside a infinite void of nothingness, it would be impossible to know if the ball was moving or not because there would be nothing to compare its motion to... yup, 100% correct, relativity is not something that can be easily and properly explained with only a few sentences lol.
im just saying i get this concept and that it makes complete sense to me....i think.

Naah, you really think you can 'stretch' your life span?
You can't, just check your wristwatch.
