if i was driving a car with a speed greater than the speed of light and i switch on my headlights.....?

Question

what will be observed???

Answer 1

you nor any one els would see any thing becous it wil never hapen in a milion years you wil nevr drive at sped faster than 299 792458 m / s it defies the laws of phisics

Answer 2

You cannot travel twice the speed of light and I don't believe that a physics teacher told someone so.

Everything is relative to the speed of light, and as a body approaches a speed -relative to other objects that are not moving as fast- near that of light it's mass goes up. Approaching the speed of light, mass reached infinity.

If you were in a car going the speed of light, (you would not be necessarily be dead btw, things would just get weird) and turned on your headlights, the light would travel away from you... at the speed of light.

Relativity seems to tun common sense on it's head, what we think we know about speed and distance and even time changes.

It is a lot to grasp, and though I suspect this is a homework question, it is a good one, because understaning relativity is essential to understanding much about modern physics.

Look it up on the web--I find one of the best places for that sort of info is Wikipedia.

Answer 3

Well, the bottom line is that a car can't go the speed of light according to relativity. This is because objects become more massive as they move faster and thus require more energy to propel them. As an object approaches the speed of light it becomes infinitely massive and requires infinite energy to move at the speed of light, which is impossible.

But let's just say that a car is going speed of light. To an observer on the ground, time in the car has stopped (because time slows down as things go faster), so the observer would never see the lights come on (because everything's frozen).

To someone in the car, yes, the lights would turn on. But please understand how ridiculous this scenario is: to the person in the car, the entire world is passing by at the speed of light, frozen in time! Just like the world sees him frozen in time! So I repeat: a car couldn't get to the speed of light in the first place

Answer 4

Firstly, since that is completely impossible that's not a question anyone can possibly answer. It's a bit like asking "What would happen if I woke up tomorrow and found I'd changed into a tomato the size of the universe?" Impossible, so unanswerable.

However, light will always travel away from any object at exactly the same speed, regardless of it's velocity. So even if you were travelling at 99.99% the speed of light - it will still race away from you at 186,000mps.

What am I doing? Your question is daft, and can't be answered.

Answer 5

A tv programme I was watching said that the light from the headlights would move away from you at the speed of light, and that to a stationary observer they would also move away at the speed of light.

The idea behind it was that time changes relative to the speed at which you are travelling.

Of course, if you can't travel at the speed of light, this theory can never be tested.

Answer 6

Let's just say that the speed of light is 35 mph. You are driving at 36 mph. You switch on your headlights and the speed of light is 35 mph. You can take it from using the famous E =MC^2 equation.
Good luck

Answer 7

I asked a similar question to my physics teacher: If i was on a plane travelling at the speed of light, and i walked from the back to the front, would i be travelling at twice the speed of light? Firstly she said i would be dead... but yes, i would be travelling at twice the speed. Not sure what would happen in this situation though

Answer 8

you wouldn't see anything as the light coming from the headlights wouldn't be able to go in front of the car. I suggest you slow down buddy, speed kills. Especially if you're driving in the dark. Slow down for christmas.

Answer 9

see first thing, when you travel or move with a speed equal to that of a light,than by Einstien's famous equation E=mc^2
u would get converted to energy,and therefore u would be able to see nothing

but also,before u will go through that conversion phase,u will see only light of the headlights

and its true,that above,because universe was also made like this,when very highly fast moving electrons slowed down until after 500million years they slowed down to that extent they started to fuse with the atomic nuclei,and than He,AND H were formed

and than supernovas formed the other elements the others heavier than iron

but buddy,u dont worry,u would never be able to travel in ur car with speed of light!

Answer 10

From an coverage attitude, you would be to blame, as regardless of what the different motive force is doing, it is your duty to tug up appropriate in the shape of an emergency, which you probably did no longer do. the subject with the motive force leaving the scene isn't possibly a topic. he's not committing an offence except he would not rfile the twist of destiny to a police station interior 24 hours. by employing returning to the scene, and related to the police, he has complied with the regulation. there are a number of the explanation why he could pass away the scene, yet regardless of his reason substitute into, no be counted if that's criminal or unlawful, it would not impression the end results of the twist of destiny which will nonetheless be your fault regardless of what he substitute into as much as. If he makes incorrect allegations approximately you leaving the scene etc, that's as much as him and the police to coach it. in case you probably did no longer try this, they have not have been given any evidence and you haven't any longer have been given something to rigidity approximately. in simple terms rfile it on your insurer precisely because it occurred, sit down lower back and enable them to handle it.

Answer 11

Einstein predicts that to reach the speed of light you would have infinite mass (E=mc2).

So on reaching the speed of light you would not be able to accelerate anymore.

BUT if you could it would be dark outside the car. All the light from inside the car would reach your eyes because its travelling at c+1 and so are you.

However the light out the car would never reach you because you are accelerating away from it.
