Faster than light speed question?

> "Scenario, I create a ship that can travel at light speed."

Well, you've violated the theory of relativity right there. There are no physical laws that describe your scenario. Why don't we reduce that to 99% of the speed of light? That's allowed by relativity.

> "...would the photons that are hitting the hull of the ship, be doing so at twice light speed?..."

No. They'd be hitting the hull at exactly lightspeed. That's one of the fundamental postulates of relativity.

> "...would it appear that earth is motionless, as i would be traveling at the same speed of earths reflected light?..."

No; and this starts to get at the heart of why you can't travel at exactly "c" (lightspeed). No matter how fast you "run away", the light from earth "chases" you at exactly speed "c". If you are monitoring events on earth, they would appear in slow motion, for two reasons:

1. You're getting ever farther from the earth, so it takes an increasingly long time for signals to reach you. This is essentially the "Doppler effect," and at 99% lightspeed, it makes events seem to run slower by a factor of about 2.

2. Because of relativistic time dilation, the clocks on the receding earth are ticking at a slower rate than the clock on your ship. At 99% lightspeed, the earth's clocks slow by a factor of about 7.

The combination of these two effects causes earth events to appear slowed down by a factor of about 14. In addition, the light from a receding object is redder and dimmer, even though it continues to hit you at exactly "c". If you could get very, very close to "c", the light from the earth would be so dim that no instrument could detect it.

> "...My idea is that it may get very very hot..."

It could. Even though the photons always approach you at exactly speed "c", their energy depends on their wavelength, which DOES change depending on your speed of approach.

> "...I also think it may appear twice as bright..."

It's worse than that. If you approach the star at 99% lightspeed, the star's photons would be about 14 times more energetic (brighter/hotter) than if you were stationary. As you go even faster, that factor increases dramatically: at 99.9% lightspeed, the photons are 45 times brighter. At 99.999% lightspeed, they're 141 times brighter.

This factor increases without limit as you approach "c": In other words, the approaching photons would have infinite energy if you could actually reach speed "c" -- another hint why "you can't do that."

According to the Theory of Relativity, nothing can travel faster than light. The photons that would be coming towards you would appear to travel at the speed of light, not more. This can be mathematically proven using relativity.

If you turn around, you will see the earth as staionary, not only in space, but also in time. Since you are travelling at the speed of light, no "new" light reaches you, and you only see the light that has already reached you and continues to reach you, travelling at the same speed as you. Somewhat similar to the way you see the light from stars thousands of light years away, and you are actually seeing what is happening thousands of years ago. The star may even have ceased to exist since.

As for photons hitting your surface, as I already said, the photons would hit you only at the speed of light, no more, thus the drag they cause is the same as they would if your ship was stationary, which would be negligible.

Making your ship reflecting would actually cause the impulse imaprted by the photons to double, not reduce, if your ship absorbed the photons.

However, you would not notice any of this, since time would effectively "stop" for you, travelling at the speed of light. Also you would have infinite mass, and zero length. All the preceding answers are based on the assumption that you have somehow overcome these difficulties.

You can't!

A ship that travels at speed of light is impossible.

Ok let's say you are in a vacuum and traveling close to the speed of light and turn on the light. The light is traveling at c away from you. That's the point of special relativity. The time is different between you and someone whose at rest according to you.

as far as i know the speed of light is constant. in other words, it cannot go faster than 186,000 mps. as far as your questions about the earth appearing to be motionless, i believe the opposite might be true. the ship would appear to be stationary and the earth would be spinning like a top. it has to do with time dilation, i think. would your ship heat up? i don't know, but if you were to suddenly hit a speck of dust or something, your ship would be destroyed. i hope this answer helps you.

The warp force works by utilising the actuality that even although remember or something with mass can not shuttle swifter than gentle, area itself can. meaning it is not the deliver that strikes, it is area that strikes by utilising the employer collapsing the gap in front of the deliver and increasing the gap in the back of it. actual it shortens the gap from gentle years to 3 hundred million kilometres. As to the G forces, there are no longer any G-forces to to be concerned approximately. The warp force isn't a great effectual antimatter rocket, yet an engine that strikes area. and because it is area that strikes and not the deliver, then there are no longer any G-forces because of the fact the deliver does not enhance up.
