the space-time continuum is very difficult to view. The problem with this, though, is that in the event time travel is achieved, they won't be able to focus on a single date; it will be random. Plus you have to realize that time is not a constant. The speed varies for everything. It travels in waves and loops, and every so often these loops will be trespassed by random people or other time waves and they will end up in, say, 1500's France as a nun for their previous lifetime momentarily.
These are called "time slips" and happen not as often as lightning strikes the same exact spot 90 times. very rare.
Anyhow, with all these time loops and waves, if time travel was possible, you could end up passing through several... perhaps thousands of loops that could land you 9 thousand years from now, or you could see dinosaurs mating. There is no direction time travels. If we could discover the direction of time flow and its interactions with other loops, then and ONLY then could they focus on a particular date.

The theory of special relativity says that as your speed approaches that of light, time in your frame of reference slows down compared to someone standing still. So if you took a long trip at a very high (sub-light) speed when you returned it would seem that you had traveled into the future because more time would have passed at home then you experienced. The equations state that as you approach the speed of light you clocks get slower until at lightspeed they stop. Then if you could go faster than light your clocks would start going backwards so in effect you would be going back in time.
The problem with this is that another part of the theory of relativity states that it would take an infinite amount of energy to accelerate anything to light speed so it is essentially impossible to do.

Time travel is possible.
Today, we know that time travel need not be confined to myths, science fiction, Hollywood movies, or even speculation by theoretical physicists. Time travel is possible. For example, an object traveling at high speeds ages more slowly than a stationary object. This means that if you were to travel into outer space and return, moving close to light speed, you could travel thousands of years into the Earth's future.
travelling at the speed of light or faster than it definitely impossible, but travelling with a velocity near that of light can be achieved in some decades in the future.
Einstein's first major contribution to the study of time occurred when he revolutionized physics with his "special theory of relativity" by showing how time changes with motion. Today, scientists do not see problems of time or motion as "absolute" with a single correct answer. Because time is relative to the speed one is traveling at, there can never be a clock at the center of the universe to which everyone can set their watches. Your entire life is the blink of an eye to an alien traveling close to the speed of light. Today, Newtonian mechanics have become a special case within Einstein's theory of relativity. Einstein's relativity will eventually become a subset of a new science more comprehensive in its description of the fabric of our universe.

Sound is the vibration of molecules and for this reason desires a media to shuttle by - with sound this media is the vibration of debris or molecules (that have mass) and for this reason can't shuttle on the linked fee of light as a results of Einstein's concept of relativity. mild has no mass and is an Electromagnetic wave - it does exhibit some properties that debris have, yet it does no longer could have a medium to shuttle in - it quite is shown by the fact we see the sunlight however the sunshine has to shuttle by area (that's a vacuum). NB... Steve C is faulty, mild has no mass yet has power and momentum in accordance to the the equation-: power = Plank consistent x Frequency. i.e. the better the frequency the extra power and momentum it incorporates. mild (or photons of the EM spectrum) are the businesses of the electromagnetic stress that could work together with remember shifting power between them. learn the Photoelectric effect and Compton scattering for extra info. No-one is familiar with for useful how gravity fits into the image, it quite is been postulated that gravity is carried by an entity called the 'gravitron' yet as yet it has no longer been discovered - it is likewise pronounced that besides the fact that incorporates the gravitational stress could shuttle on the linked fee of light. If somebody discovers the 'gravitational service', there is not any doubt there'll be a nobel prize for them, as this might finished what's familiar as a results of fact the 'time-honored form' in physics.

first of all get it clear nothing travels faster than light absolutely nothing!!!
second to reach at speedsnear light is far thing the fastest rockets travel about 50,000kmph that is far from the speed of light
300000kmph
the effect of mass plays a critical role as u go faster ur mass tends to increase when u reach speed of light ur mass is infinity
an impossible situation u will have to be massless to travel at the speed of light only a photon is massless that is why it travels at the speed of light

since increase in speed will increase mass in direct poportion and since increase in mass would afec he pseed in indirect poportion , there is no questiomn of any particle heavier then the particles of photons assuming the speed even equal to tha of light . leave alone anyhng heavier han phon exceeding he speed of light .How can any body travel a a speed higher than that of light a any time . Even God can no do that . It is a scientific impossibility even for eternity.
howeer hare is one way to do it . We must become a particle musn less in mass han the sub-atomic photon . We can travel faster than light !

NO WE CANNOT! IT IS COMPLETELY IMPOSSIBLE! Would you like to know why? Because Einstein stated weaved into the theory of reletivity that mass is increased with velocity. If anything aside from light reached the speed of light then its mass would be infinite and nothing would beable to propel the object! Who ever answered the question first was completely mislead.

according to relativity we can travel in time if and pnly the speed is greater than light.most probably the warm holes provides such situation.
some tackion particles can travel faster than ligt. if we can transform such electrons,protons, nutrons in such particle than it could be happen.
