The faster an object moves, the more mass it has. The more mass it has, the more energy it requires in order to continue accelerating. At the speed of light, mass becomes infinite, meaning you would require an infinite amount of energy in order to accelerate further.

There is not enough energy in the universe to accelerate anything beyond the light barrier.

We haven't done it, so it can't be done????

hmmmmmm..

Every generation believes it's at the pinnacle of knowledge, and there's nothing more for us to learn.

I wouldn't be too sure about that.

My suspicion is that we're operating under some facts, and a whole lot of fallacies.....

Just like everybody before us.

I could be wrong.

Could you??

No, its not just because we haven't done it. The laws of physics prevent it...

In order to break the light barrier, you would need infinite energy. The universe's energy is not infinite.

You could take the combined energy of every star in the universe, and you still wouldn't break light speed.

The speed of light is the speed of light. It cannot exceed itself. Nor can we exceed it.


But as if to knock me down, reality came around
And without so much as a mere touch, cut me into little pieces

RE: Can the speed of light (299,792,458 m/s) accelerate?
So what would happen in this situation:
Let's say the red dot is a ray of light that starts at the speed of light, why wouldn't it follow this model (assuming the earth is a black hole) https://www.youtube.com/watch?v=I3F88w3LkiI

why can't the ray of light be accelerated if it ran into this type of situation?

But wouldn't there have to be something faster than light?... Its been proven that light cannot escape a black hole, so could it be fair to assume that the force that a Black Hole exerts on light is accelerating light into itself at a velocity far higher than the speed of light?....

Gravitational fields propagate at the speed of light... As light approaches a black hole, its direction will be pulled and changed. If it approaches the black hole just outside the event horizon, it will loop around the black hole. The black hole will affect the frequency of the light along its journey, but never its speed. If the light crosses the event horizon, it is simply close enough that instead of looping the hole and escaping, it will loop it again and again until it reaches the center.

The event horizon is just a point of distance from the black hole itself. Beyond that point, it doesn't mean that something has exceeded light speed, it is simply bending the light more than would allow escape.

I believe gravity fields can only affect the wavelength of light.

To use a large body for accelerating another object, both would need to have mass. As a ship loops around a black hole, it uses the powerful gravitational field to leech off some of the black hole's momentum, which is only possible because the ship also has mass and a gravity field; light doesn't have mass, so it won't pull on and leech from the black hole.

Because the laws of physics don't allow it. I've already explained this to you, as have others. The velocity of light is invariant, having the exact same value in all reference frames. The theory of General Relativity stands on that fact, and it has produced results that are in line with said fact.

The truth is absolute. Life forms are specks of specks (...) of specks of dust in the universe.
Why settle for normal, when you can be so much more? Why settle for something, when you can have everything?

It doesn't.... That's why I put it there....

It's called a counter, to your sidetracking with a minor point.

We KNOW they were wrong - so what's the point of arguing about who was wrong, when???

Fun, huh??

Big Grin

You haven't demonstrated any scientist believed what you claimed. Asserting it doesn't make it true, and "they were wrong about this, so they must be/probably are/may be wrong about that" is a fallacy.

hmmm I thought light does have some mass. You sure it doesn't?
*EDIT* Upon research, i guess it doesn't. THAT explains it. other people are just rambling about off topic stuff that doesn't relate to my question or they don't validate/explain their claims. Grrr frustrating Tongue Thank you!

why is the velocity of light invariant? Can you explain why? or is it because we have yet to observe it, like many other things?

Photons have no rest mass. That's why they never stop moving and why they travel at the fastest possible velocity.
