Theoretically if you could travel faster than light and looked back, time would be going backwards, but what would you see if you looked forward ?

As you approach the speed of light, time becomes relative. Your watch will tick slower than another watch on your home planet. Looking to the rear or front or to the side of you will not matter. You cannot see time other than looking at a distant star and seeing the light it gave off according to the time that it took for the light to reach your eyes. Faster-than-light travel is prohibited under Einstein's theory of relativity. Unless you are speaking of a fictional theory. If so, then your only limit is your imagination.

The fact that you're exceeding the speed of light wouldn't really have much effect on what you could see looking forwards - when you look forwards you see time compressed - images reaching you arrive faster than they were originally transmitted because you're meeting them on the way. When you go at light speed or beyond this effect simply increases, so it will seem very speeded up. By contrast, when you look backwards you won't see anything, as light will be unable to keep up with you.

The the doppler effect would cause everything coming towards you to appear violet, hypothetically. That's how astronomers can tell of an object is moving away from or towards Earth. If it appears red then it is moving away because the light is being stretched. If the object is moving towards Earth it appears blue because the light waves are being compressed. One of the things I remember from astronomy. This is all hypothetical because technically nothing can travel faster that light and if you were traveling the speed of light you would in fact become a beam of light.

If U were approaching the speed of light and looked forward U would see nothing as light would be Doppler completely out of the visible light spectrum . This is another problem u would not be able to look forward even with radar. could run int a sun or something.

WHEN YOU TRAVEL FASTER THAN LIGHT
AND LOOK BACK YOU WILL NOT SEE ANYTHING!!!
anyway I just love your question...got me tinkering for quite sometime.
as you can see when my dad studied Chemistry in the 8th grade he was told that Atom was the smallest Particle known to man.
Now...there are many divisions of units inside the atom like nucleus, electrons, protons and quarts...
When you travel faster than the speed of light and look back, you will NOT see time going backwards.Rather the only thing that will be there is darkness
WHY?
well its all in the relative speed
The concept that helps us to see objects is the fact that the light that is reflected or bounced from the objects hits the retina and helps us to see.
When you travel faster than the speed of light you wont be able to see anything because the light that is bounced on the object is also traveling at the speed of light.which means that reflected light will be traveling close to you but will never reach the retina as you are traveling faster than light.
Unless you slow your speed... speed slower than that of light just a bit you wont be able to see whats happening.
Also If you were Traveling at the same speed of light the same thing would occur.nothing. just darkness.
Consider a car rally
If the first car took off and attained a speed of 60mph and holds speed.
then the second car which started off 5mins behind you and also reached 60mph and remains at 60. The truth is unless the second driver hits it higher there is no chance that he will come to the side of the first fella. They both will be having a constant distance between them till the finish line.
Now consider whats happening in front of you through your journey faster than the speed of light.
Now this gets complicated and a bit of logic i guess.
The object in front(dead north of you) will appear quite bigger than they actually are!as you are headed in its path and you would intercept the light midway...as you traveling towards it.
but nothing at the sides as the light reflected or produced from these objects will never reach the eye.
Imagine going in a car and keep your head steady...you will see that the left and the right will appear in strands while at the front it is a clear view. as your moving towards it.
Now hope my ideas got through to you.

According to Einstein, the speed of light is the maximum speed that anything in the universe can attain. But if you were going faster than the speed of light, you wouldn't see anything because light wouldn' t catch up with you, you would have to slow down below the speed of light to see anything. It' s like the speed of sound, if you go faster like in a plane, you don' t hear any sound from the plane, it is silence ,

If there was anything in front of you then you would be seeing it speeded up (and approaching VERY quickly!!).
Not very exciting really I'm afraid. No visions into the future or anything!!
Imagine 2 sets of ripples on water. You are travelling away from one set and towards another. The ones you are heading towards will pass by quickly (it certainly wouldn't be black!), and the ones you are travelling away from will be being slowly overtaken.
Should point out I've ignored points such as whether your eyes would actually work etc. I'm presuming that this wasn't what your question was getting at, and unlike some of the pedants on this answer I'm not going to even point out that it is "impossible to travel that fast"....

good adequate. Time does now no longer pass slower for speedy products. apparently to you, assuming you need to be table certain, that factor is passing slower for speedy products. If there are no accelerations advantages - each little thing is consistently shifting on the equivalent speeds relative to a minimum of one yet another - then there isn't any thank you to tell who's moving and who's at rest. Now the twin paradox, which you style of paraphrased right here, has 3 accelerations in it. you start up from entertainment and accomplish an extremely intense velocity. After a time, you turn around this ability which you slow down, you momentarily quit, and you velocity as much as a intense velocity back. hence you attain earth and slow to a stop. At each and each acceleration, you adventure a force which the earthbound man or woman does no longer so it particularly is sparkling who's in stream and who's at rest. hence, you are going to return after 10 years it slow maximum efficient to look for out that a lots longer time has handed on the earth. Now megastar trek assumes there is the thank you to journey exterior of the 4 dimensional area that defines the universe - the so-widespread as subspace. in this subspace, relativity does no longer carry on with - it particularly is exterior the universe noticeably lots - so so you might pass from factor to factor in a finite volume of time and, the time it takes to traverse the hollow as measured via the starship's clock may be the time that elapses interior the universe - style of no longer likely in spite of the shown fact that essential in case you're writting one hour long television episodes. there isn't any information for this style of commute use in well-known man or woman trek.

If you were going faster than the speed of light, you would not be able to see anything since the human eye needs light to perceive objects at ANY range....

If u could ever travel at the speed of light at 186,000 miles per second,you would know the answer before you asked the question.?
