Gravitational Waves. oh really?

Again, "I don't see anything in that post about how action-reaction has anything to do with velocity addition at relativistic speeds."

you don't see?....and it is sooooooo simple....

anyone else confused about #147?

I think I got it. You've been in an accident once at 60 mph.

Therefore you can somehow add up velocities instead of using Newton's third law. Something like that?

It's forces and energy that adds up. Velocities are the results.

Are you going to stop beating around the bush or are you going to draw this out for no reason? Action-reaction has nothing to do with the fact that you can't add up relativistic velocities.

I cannot open your eyes for you.
you have not declared WHY the post is irrelevant.

so you had some objection?....147

velocity was in play BEFORE the impact.

let's see....how does it go?
an object moving slowly has less energy as the same object moving quickly...................right?
and a collision of two items.....slowly is no big deal
the same two items at 60mph.....bumping side to side......oooops!
the same two items at 60mph head on.......dead meat

two items head on at the speed of light......annihilation....

It's transference of energy, not speed. There's something called kinetic energy. That's at play more than just velocity. Also, mass comes into the equation, not just speed. And drag, friction, direction, and properties of the objects like density and hardness and such. For instance, does the energy distribute?

With light, the energy is translated into higher frequency instead of velocity, that's why it keeps the speed. E=hf. Energy = Planck's constant (about 6.6 x10-34) * frequency.

With speed then gravity, suddenly !
Speed stops, and so the other speed !
And then only gravity,
gravity wins !
Pick up that trash will ya !

I just did: action-reaction has nothing to do with the fact that you can't simply add up relativistic velocities. Kinetic energy isn't linear at relativistic speeds either. Technically, it's not linear at any speed. Travelling twice as fast at non-relativistic speeds gives you four times the kinetic energy. Yet travelling at 0.9c does not give you four times the kinetic energy as you would have at 0.45c, it gives you more than that.

and passing an idle train looks the same as passing a train moving the opposite direction?
anyone else not understand 147

Actually, when the train passes, visually it looks like the other train is slowing down for a moment.

And you know, the sound waves, travel in constant speed both directions. Only the frequency and wavelength changes, but the seed (frequency times wavelength) is 340 m/s (depending on weather, altitude and air conditions).

Just like the air sound speed depends on the quality of the medium rather than the speed at which the sound generator is going at, speed of light changes depending on the medium and gravity, but not on the speed of the flashlight.

It didn't do anything to refute relativity, that's for sure.

motion is relative.

as a train approaches, sounding it's horn.....the pitch will 'sound higher'
as the train has passed and continues to sound off....the pitch will 'drop'
Doppler effect

the engineer hears the same note (pitch) at all times.
he would be moving with the source

sound waves that collide head on.....do so in addition to each other.

sound waves as they approach.... higher pitch
as they recede.....lower pitch
the effect is heightened if you are moving

 

[Thief]

Do you think the Doppler effect is in play for gravity?

maybe so.....check the Vomit Comet

And the reason to this is...? Frequency, not speed.

The velocity of the moving train, going towards you or leaving you doesn't change the velocity of the sound. It does however change that frequency of the sound. If the velocity was changed, they would have the same frequency, but they don't. So, speed is unchanged. That same goes for light.

If you would go in a high speed spaceship and turn on a flashlight aimed forward, someone seeing that light would see a blue-shifted light because it has higher frequency, but it would also have a longer wavelength, according to the v=f*lamba equation. If you would light it back, someone seeing it would see a redshifted light, lower frequency, lower energy, and longer wavelength, but not faster. In both situations, the speed of the light would be exactly the same, 300,000 km/s.

Do you know the equation for the velocity of a wave? You seem to read what you want and conclude that frequency has something to do with the speed of sound. It doesn't. The speed of sound is constant, the frequency and wavelength is what changes. Do you think that frequency and speed are the same thing?

Doppler effect is the effect of change in frequency because of the velocity, not that the velocity of sound changes, but that the frequency changes.

"The Doppler effect (or Doppler shift) is the change in frequency of a wave (or other periodic event) for an observer moving relative to its source. "

Perhaps you need to pick up a physics book instead of making jokes about puking?

"speed of sound at sea level = 340.29 m / s"

speed has everything to do with the reception of sound

I don't think gravity moves in waves....as does sound.....
but moving WITH a falling object makes it appear.....gravity is not in play
illusion

The speed of sound is constant. Look it up.

??? Not sure what you're getting at.

??? Still not sure what you're getting at.

Speed of sound is constant in a given medium and conditions. And putting a speaker in front of a train or in the back of it, the speed of the hearing sound is still constant. Only frequency and wavelength changes.

And the same goes for light.

That's how it works. That's how all experiments show.

 

[Ouroboros]

Huh?

And?

Therefore speed of light can change because your puke floats? Disgusting and completely irrelevant.
