In summary, a photon has no rest mass, so it doesn't need to accelerate. If it does have to accelerate, it does so over a finite time and violates the laws of classical physics.

I have been wondering wether a photon has acceleration or not, how does it reach the 300,000 km/s? does a photon even need to accelerate?

I would also appreciate your telling me about rest mass, how does it work, what does it cause, etc.

An acceleration is a change in velocity. Photons always move at the speed of light, as do all massless particles.

There's one thing though. A photon does have momentum, so when an atom emits a photon it has to recoil slightly.

Well, what Woz is trying to ask is, how does it start moving in the first place... maybe.

It takes an infintesimal amount of energy to accelerate a luxon, a particle with no rest mass, such as a photon, but not zero. Once it gets accelerated to the exclusively luxonic speed of the speed of light in a vacuum, from that infintesimal amount of energy, it needs no more, it doesn't slow down or speed up, unless of course it goes through a medium.

It may be absorbed or scattered but always propagates at C.

The photon is propagating at c as soon as it is created. It is not that there is initially a photon 'at rest' that needs to be accelerated to c.

When was this "luxon" experimentally discovered or verified? Oh wait... it hasn't?

Then why are you using a hypothetical particle to contradict something that HAS been experimentally verified, and has an unbelievably accurate theory (QED)? That's like using a pseudoscience to disprove a science!

Take note of the statement already mentioned, that if a photon has to accelerate, it means that over some finite time, it IS NOT traveling at c in vacuum! This violates SR! We need to shake a few people up so that they somehow can get free from the classical Newtonian mechanics here...

What is photon acceleration?

Photon acceleration is the process of increasing the energy and speed of a photon, or particle of light, through various methods such as using electric fields, magnetic fields, or intense laser beams. It is an important concept in the field of physics and has potential applications in areas such as particle physics, imaging, and energy production.

How does photon acceleration work?

Photon acceleration works by using external fields to accelerate photons. For example, in the laser-based method, a high-intensity laser beam is focused on a target, causing the electrons in the target to oscillate and create a strong electric field. This electric field then accelerates the photons in the laser beam, increasing their energy and speed.

What are the potential applications of photon acceleration?

Photon acceleration has many potential applications, including medical imaging, cancer treatment, and particle physics research. It could also be used to develop more efficient and powerful light sources for technologies such as solar panels and lasers.

What are the challenges in achieving photon acceleration?

One of the main challenges in achieving photon acceleration is creating strong enough external fields to accelerate the photons to the desired energy levels. Additionally, controlling the direction and stability of the accelerated photons can also be challenging. Researchers are constantly working to improve and refine the methods used for photon acceleration.

How does photon acceleration relate to Einstein's theory of relativity?

Photon acceleration is related to Einstein's theory of relativity because it involves the acceleration of particles, which is a key concept in the theory. Additionally, the energy and speed of the accelerated photons can approach the speed of light, which is a fundamental principle in relativity. Understanding photon acceleration can also provide insights into the behavior of particles at high energies, as described by Einstein's theory.
