Speed of Light

Nothing.

Your perception of the laser light might change.

Are you inside the spacecraft?

Outside the spacecraft?

Etc?

Depends...

Take a physics class including red/green-shift calculations. Do not assume 100%c.

Such a brilliant rhyme, my darling. Impressive.

He'd go with everyone!

"If a man in a forest says something and there is no woman there to hear him... is he still wrong?

Go ask Mrs. Cat, I'm sure she will have an answer!

Or was Einstein 112 years early? Can you tell this in your inertial frame of reference?

Humans.

Lovely inspiring thought, lacking the power to see beyond the kitchen window, yet making biscuits of wonder perfectly suitable for the tea ceremony. How will we ever reach out and touch the stars? We already have. We are the stars (dust).

Speed is relative, you have to specify speed in relative to some reference, for example, the earth. Nothing except light can travel at the speed of light relative to anything else, and light always travels at the "speed of light" relative to everything.

There is something in the eyes that would probably help explain light.

Questions like

1. how do you perceive light?
2. does optical sensory conforms hi-tech light technology?
3. What type of conversion there exist converting photons to neural transmission?

so on and so forth...

What torch?

It's all relative.

Depends if the lasers are able to operate in that ambient temperature range. It's pretty cold up in space.

Huge Doppler Effect, one will be reduced to a low frequency virtually nil, since you specify v=c. The other will be very high frequency. I think your laser will blow up in the "head wind" of interstellar gases.

This is in the supposition that something scatters the beams in order for stationary observer in other frame of reference to actually observe the beams.

Otherwise if directly behind the craft, does the beam ever make it out of the event horizon? If directly ahead of the craft, how can the beam propagate fast enough to reach observer before the craft. I suspect a collision of immense energy takes place.

"Assume/Imagine a spaceship travelling at the speed of light. Two lasers are mounted on top of the craft. The 2 lasers are mounted in such a way that, 1. Pointed forward 2. Pointed Backward What will happen to the laser coming out of the torch"

Thank you all for your valuable comments. The above question I asked is just to understand "what is light".

What if an observer is stationary?

1. For pointed forward: Will the light velocity be doubled
2. For pointed backward: Will the light velocity be zero

In addition to this, is it possible / sensible to compare the above scenario with a bullet coming out of a pistol, mounted on a spaceship whose speed is equal to speed of a bullet.

What would be the fate of the light and the bullet for a stationary viewer?

Doppler effect - Wikipedia

Study the Doppler Effect.

<...is it possible / sensible to compare the above scenario with a bullet coming out of a pistol, mounted on a spaceship whose speed is equal to speed of a bullet..> No, it isn't, because bullets don't usually travel anywhere close to the speed of light; speed of sound in air at [temperature/pressure], maybe. Plus, there is by definition no air in space. So the conjecture is absurd.

Read post 6. Del has it right. The speed of light is constant, no matter your frame of reference. So both lasers will fire at the speed of light.

The problem is who is going to fire the lasers. The person on the spaceship, who according to you is already travelling at c, will have a time reference frame that is stopped, so it will take him to infinity to press the button.

As stated in another previous post, you should talk about approaching the speed of light, not travelling at c.

What is light ? The absence of, which is impossible, because in the absence of light there still is light, although not in our visible spectrum. Like asking what is cold ? Even in extreme cold there is still heat or warmth.

em 'em

their they're

They spoke a different language, grammatically tomorrow.

Thus, this thread was over before it began.

Sounds like yur busted before you go anywhere.

Although the spacecraft is moving at the speed of light ( define light spectrum ? ) . What is the speed of the lasers ( define light spectrum ? ) Are the lasers mounted side by side ? What is the length of the craft ?

The speed of light is the same no matter the spectrum. You are talking frequency.

It's like the speed of sound. The tone does not change the speed of sound.

Same goes for rumors, the tone does not change the speed of the rumor.

Ahhh Rumors excellent album.

There will be absolutely no change in the spacecraft or the lasers from pre- to post-firing.

Time dilation increases as speed increases, as speed approaches C, time dilation approaches 0. Traveling at the speed of light, time will stop in the inertial frame of the ship. If t is a fixed, unchanging value then there can be no change of state within that single fixed instant of t.

-----

Now if you change the chips speed from C to 0.99C, then the question can be answered.

From an observer within the ship:

The lasers will spear out from the ship, both traveling at the same speed (C) away from the ship.

From an observer on a planet the ship is passing near, as no maneuvers have been stated the ship will be considered to be traveling at a tangent to the planet, neither flying directly towards nor directly away:

The lasers will spear out from the ship, both traveling at the same speed (C) away from the ship.

This has been a quick lesson in relativity and inertial frames.
