Einstein was a true truth seeker.

His Nobel Prize is for photon/quanta theory not relativity.

Why scientific community don't take his word seriously? He was the godfather of quanta. Quantum anything is imaginary.

It's not like you take his word seriously either, given that you just got finished saying, "quantum anything is imaginary".

Did he said he knows not what are light quanta?

Why is that? Was he invented quanta? Was he won Prize for photon theory?

Did he said everyone thinks they know what are light quanta are mistaken?

I take his word, that why quantum anything is imaginary.

Saying that you don't know what something is is not the same as saying that it doesn't exist.

What is photon made of? How photon is emitted? What is the difference of red and blue photon?

How can photons pass through water without losing momentum and stop?

How can photons accelerate from glass into air?

Where are all the photons from all the stars shooting at us?

I answered that in another thread already.

Quote from: seeker3 on 26/03/2019 06:37:09
How photon is emitted?

I answered that too.

Quote from: seeker3 on 26/03/2019 06:37:09
What is the difference of red and blue photon?

Wavelength, energy and frequency (all three of these things are related for light).

Quote from: seeker3 on 26/03/2019 06:37:09
How can photons pass through water without losing momentum and stop?

They don't work the same way as physical objects like bullets. It's at least in part due to their wave-like nature.

Quote from: seeker3 on 26/03/2019 06:37:09
How can photons accelerate from glass into air?

Because air doesn't slow light down as much as glass does.

Quote from: seeker3 on 26/03/2019 06:37:09

They are either absorbed or reflected by the matter here on Earth.

What is energy? How photons carry energy? What frequency? What wave length? What mechanism? How photons vibrate? How photons wave? Why all photon have same speed? Why photons slow down in water?

Does photon carry electric field and magnetic field? Does photon carry EM wave? How exactly photon move or wave through space? what is exact mechanism?

Those are a lot of questions and I don't have time to answer them all tonight. This video, however, could be of help:


Part of the answer to your questions is that electromagnetic waves are composed of changing electric and magnetic fields at right angles to each other that create new changing electric and magnetic fields and so on and so on. That's what causes the wave to propagate through space. A photon is simply the smallest possible piece of that wave.

This may help as well:

If photon particle is real particle, to accelerate it to light speed takes energy, and a precise mechanism, and time. How come light accelerate from 0 to light speed instantly?

WHAT IS THE MECHANISM?

So the Sun shooting out photons at every direction at light speed?

Does Sun's gravity slow down photons that shooting away?

Why photons are not slowing down by time since gravity is constantly decelerating it?

Not on topic.

You need to know physics at a fairly deep level to have any hope that your questions are answered. Especially you need to know QED. Even so, you are going to have questions that cannot be answered. The universe does not reveal its secrets easily. Check out https://www.researchgate.net/post/Is_Einsteins_photon_really_the_same_as_the_QED_photon for an example of the controversies raging in physics over the photon.

If gravity can attract light, slow down light, so very big mass can become black hole because light slow down to a stop?

If that's true, half black hole mass star light speed should be 1/2 light speed?

Small Sun's light speed faster?

Gravitational lensing might be caused by hot gas plasma on the surface of the Sun or gas clouds in deep space deflected light.

WHAT IS THE MECHANISM?

Photons don't accelerate from zero speed to light speed. That implies that they start off at zero speed when they first come into existence. They don't. They are moving at the speed of light as soon as they are created. So there is no acceleration.

Yes.

Quote from: seeker3 on 26/03/2019 07:46:18
Does Sun's gravity slow down photons that shooting away?

No, but it does weaken them so that they have less energy.

Quote from: seeker3 on 26/03/2019 07:46:18

Gravity doesn't decelerate light.

No, black holes redshift light out of existence.

Quote from: seeker3 on 26/03/2019 08:04:36

Small Sun's light speed faster?

No, the speed of light doesn't depend on a star's mass.

It isn't. The amount of lensing matches the mathematical predictions of a gravitational cause.

@seeker3
Posting multiple questions without waiting for an answer is also trolling, as is advertising new theories in this section of the forum.

What is the mechanism of light? How electrons emit photon? How photons travel in space at light speed? How photons slow down in air and water? How photons accelerate from water into air? How photons carry energy? What is energy?
