If you could travel faster than the speed of light?

Question

is time moving backwards or forwards?

Answer 1

This is kind of a moot point because your mass becomes infinite as you approach the speed of light, therefore the energy required to accelerate you to the speed of light would be infinite and thus not possible.

Time slows down the faster you go and at the speed of light would be zero...One could deduce that if you were to go faster than the speed of light time would then move backwards...That is of course if you could get beyond the infinite energy issue...

Answer 2

If Lorentz and Einstein are correct, then, for us who are observing you, we would see your length as L/gamma
where gamma is 1/ SQRT(1 - v^2/c^2).

Apparent length = real length * SQRT(1 - v^2/c^2)

Because your speed v is greater than c, then the value inside the bracket is negative; we need to find the square root of a negative number. Can't be done with real numbers.

This can only be done if we use complex numbers (where i represents the square root of minus one). A complex number is of the form a + bi, where a is the real part and b is the imaginary factor.

When wording in 1-Dimension in the complex field, we imagine the 'imaginary' part (the factor of i) to be at 90 degrees from the real numbers. On a piece of paper, we'd show it as a 2-D value, like a x,y graph, but that is not really what it is. The complex part would be 90 degrees away, in a direction that we do not know.

When v is greater than c, SQRT(1-v^2/c^2) is a purely imaginary number (meaning that there is only a product of i, the 'real' number portion 'a' is zero), therefore your length would have to be 'imaginary' (whatever that means in a 3-D world). Your vessel would appear to be turned in a direction that is 90 degrees to all the three directions we know in our space. The real portion (the only one we can perceive in our space) is zero.

From our viewpoint, your time flow would appear to be t*gamma: an interval of one second on your vessel would look to us like 'imaginary' time. In other words, for us observer, your time flow would appear to be in a different direction than ours (but not necessarily backwards!).

Einstein's theory says that there is no preferred frame of reference. To you, your length and time flow would appear normal. To you, it would be the rest of the universe going faster than light: the rest of the universe would appear, to you, to have turned 90 degrees away from your perception of 3 coordinates (90 degrees from all three!).

Who knows where (and when) you end up.

What the theory shows is that any object that has mass cannot attain (or surpass) the speed of light. The speed of light itself is forbidden for a massive body that tries to accelerate. The theory does not forbid objects that are (already) going faster than light (called tachyons). It's just that nobody knows how we could ever observe such a thing or if they even exist.

Since you were going slower than light at the type you typed your question, it would appear that you are stuck on our side of the speed of light...

Answer 3

Sound is the vibration of molecules and subsequently desires a media to holiday with the aid of - with sound this media is the vibration of debris or molecules (that have mass) and subsequently can't holiday on the fee of light as a results of Einstein's theory of relativity. easy has no mass and is an Electromagnetic wave - it does demonstrate some homes that debris have, yet it does not would desire to have a medium to holiday in - this is shown with the aid of the reality we see the sunlight however the sunshine has to holiday with the aid of area (that's a vacuum). NB... Steve C is faulty, easy has no mass yet has potential and momentum in accordance to the the equation-: potential = Plank consistent x Frequency. i.e. the better the frequency the greater potential and momentum it incorporates. easy (or photons of the EM spectrum) are the businesses of the electromagnetic tension that can work together with remember moving potential between them. study the Photoelectric consequence and Compton scattering for extra information. No-one knows for confident how gravity suits into the photograph, this is been postulated that gravity is carried with the aid of an entity called the 'gravitron' yet as yet it has not been got here across - it is likewise mentioned that regardless of incorporates the gravitational tension would desire to holiday on the fee of light. If somebody discovers the 'gravitational provider', there isn't any doubt there'll be a nobel prize for them, as this might finished what's time-venerated as a results of fact the 'prevalent style' in physics.

Answer 4

its moving observationally backwards (This is just my thoughts, and im not some fancy pants scientist). Say you moved faster than light from the earth to the moon, then turned around and looked at the earth, you would be looking at events that happened in the past (how far in the past depends on how far and how fast you moved)

Answer 5

If you believe Einstein's theory, time slows the closer you get to the speed of light and stops at the speed of light. But he also said you cant go FASTER than the speed of light. Sort of a universal speed limit.

Answer 6

first off time is the creation of the human mind---time is the interval between ANY two events--be it the big bang untill now --or the interval of the tick tock of your clock--the speed of light is just a number--the biggest that is observable--light can bend or stop or disappear (aka black hole)--let me ask you a question--does light have mass? does a light bulb that's on weigh more than one that's off? whether you believe in the bang or god, everything started out as ONE, and eventually we will return to the one. enjoy your interval in this life!!

Answer 7

forwards ofcourse. time has nothing to do with the distance you are travelling. but you can live longer. time is constant when you are in a spaceship traveling faster in the speed of light. only distance is affected, not time.

Answer 8

First of all I'm not sure Einstein got all of it right.

Einstein did say man allicamates.

It is possible the aging process continues as before.

It is CLOCKWORK time that slows.

If you were a Tachyon, theortiecally you'd have to be outside of Time and Space as we know it.

Answer 9

if i was traveling faster than the speed of light my concern
would be that cop who has been following me since Jupiter !!

Answer 10

time moves at the same measurement at any speed. they say we can`t surpass the speed of light, but they told Wilber that you can`t fly too! Well, I guess time will tell
