Can a Photon Exist Without Speed?

[Hippasos]

Can there ever exist such a thing?

And if yes how could it be observed?

Thanks!

No, photons and all other massless particles are required to travel at c.

I can say that it is not possible for a photon to exist without speed. Speed is a fundamental property of all particles, including photons, and it is defined as the rate at which an object moves through space. Photons are particles of light that travel at the speed of light, which is approximately 299,792,458 meters per second in a vacuum. This speed is a fundamental constant and cannot be changed.

The concept of a photon existing without speed is contradictory and goes against the laws of physics. Without speed, a photon would not be able to travel through space, and therefore it would not be able to carry energy or interact with other particles. In other words, a photon without speed would essentially not exist.

In terms of observation, it is not possible to observe a photon without speed as it would not be able to interact with any detectors or instruments. The very act of observation requires the photon to have speed, as it needs to travel from the source to the observer's eye or instrument. Therefore, it is not possible for such a scenario to exist in our physical world.

In conclusion, it is not possible for a photon to exist without speed. Speed is a fundamental property of all particles, and without it, a photon would essentially not exist. Furthermore, it is not possible to observe such a scenario as it goes against the very nature of observation.
