A pause in shining light??

Question

If a planet, or something putting of light was suddenly flung from its pont of origin and was moving faster than the speed of light, and for instance your were at the point of origin, and you were looking at the planet hurlling away from you, would the light still reach your eyes because it was at 1 time where you are? I know thats kinda confusing but thats the reason Im asking it.

I know thats kinda confusing but thats the reason Im asking it. I realize this is impossible to happen, but again its is purely and IF situation.

Answer 1

yes you still see it, its time, speed,light speed, you see it theen not,lights out like aburst,

Answer 2

The scenario you describe is impossible for several reasons, of which the main reason is that stellar objects are not "flung" and do not approach the speed of light.

In general theory, a luminous object moving away from you at the speed of light would be invisible to you. In reality that is not possible.

Answer 3

First of all :
NOTHING moves faster than light.
NOTHING : Material moves as fast as light.
Please get that straight, it's part of what is confusing you.

With that out of the way:
If a distant object suddenly changes in some way, you don't see that until the light from that object reaches you.
When you look out in space, you look back in time.

Answer 4

this is impossible. once an object approachs the speed of light energy is no longer input as velocity but as mass. so it gets more massive and the energy required to move it increases, more energy is used and it grows more. its a paradox, an object can never reach the speed of light.

Answer 5

Your question is easy to answer.

For your "planet or something putting off light"

I chose the "something" as a flash light.

Light is often worked on as a wave or a particle
Now to get you moving I chose for you, a light particle surf board riding half way down the face of the wave.

Your surfboard and your wave leave the big flash light.
You, your surfboard light particle, and thw wave you are riding on are all moving at exactly the same speed so to you they look like they are standing still.

You said you look back toward the light source. Out of the flashlight you see another wave and another surfer emerge.
They are not gaining on you and not falling back so they must be going at the same light speed as you..

Now you said the light source picked up speed and started going away from you so that it was moving faster than the speed of light.

Let us take the speed up gradualy. the third surfer's wave seems to take longer come out. Her wave is longer the face of the wave where she is is not so steep. The top is still as high and the bottom is atill as deep but the distance from you is much further than the first surfer. as the light moves faster and faster. more surfers emerge but the come out further and further apart.

None of the surfers ever catch up with you because you are all moving at the same speed.

By now you are saying But! But! Yes now you recognise the problem. your "eyes" must be able to see faster than the speed of light if you are going to "See" any of these things.

Hearing them is out, because hearing happens at the speed of sound sight is out because you are moving at the same speed and in the same direction as the light that is trying to reach you so we close our eyes and imagine all these tthings.

We conclude that things get weired when the sence organ is moving in the same direction and at the same speed as the thing we are trying to sence. For that particular sence organ there is nothing changing so you say to yourself nothing is happening. but your brain says but we are moving at the speed of light but your mind says the surfer behind me is still there but will not catch me. the surfer in front of me is still ther but I will not catch him. Very boring. Time is stopped for all of us traveling the same way.
What about the flash light itsself? can I see it. No because seeing requires light and each light particle that leaves the light and heads in my direction never catcdes up to me so they never get to my eye.

But I am using my mental imaginative powers! That can see faster than light!.

OK if you insist.then this new sence organ of yours is just like the difference between you ears and sound.you get dopler effects.
Insted of hearing changes in pitch you notice shifts in color..

Remember hearing about red shifts? When things are moving away from each other at even small percentages of the speed of light we see those things as slightly reder.

Final answer please!
First restriction. Your eyes do not see faster than light.
Second restriction. The fastest local change that happens is the motion of light particles.

The light that reaches you for the time that the planet is where you are but as soon as tthe planet reaches light speed away from you any liight coming from the planet would not reach you so you would not see it. Same with any light leaving the planet moving away at faster than the speed of light. The light would dot reavh you.

Kinda confusing? yes but slowly understanding the concepts is enjoyable. That is why I am writing the book.
