Can a photon experience time?
Yet despite this incredible journey, the photon itself experiences none of what we know as time: it simply is emitted and then instantaneously is absorbed, experiencing the entirety of its travels through space in literally no time. Given everything that we know, a photon never ages in any way at all.
Is a photon a particle?
Secondly, the photon is now thought of as a particle, a wave, and an excitation—kind of like a wave—in a quantum field. A quantum field, such as the electromagnetic field, is a kind of energy and potential spread throughout space. Physicists think of every particle as an excitation of a quantum field.
Is a photon the fastest particle?
The idea of neutrinos that move faster than photons would seem to violate the notion, based on Einstein’s theory of relativity, that nothing can travel faster than light. Einstein’s theory of relativity “just states that no particle can travel faster than a massless particle,” Heeck said.
Is a photon everywhere at once?
Presumably when a photon interacts with another particle (or is observed) it slows down and no longer travels at the speed of light i.e. no longer existing ‘everywhere’ at once.
Is a photon timeless?
Photons do not experience time. From the perspective of a photon, there is no such thing as time. It’s emitted, and might exist for hundreds of trillions of years, but for the photon, there’s zero time elapsed between when it’s emitted and when it’s absorbed again.
Can photon be destroyed?
Photons are easily created and destroyed. Unlike matter, all sorts of things can make or destroy photons. Similarly, when a photon of the right wavelength strikes an atom, it disappears and imparts all its energy to kicking the electron into a new energy level.
Can phonons travel faster than light?
Science: Can photons travel ‘faster than light’? LIGHT cannot travel faster than it does in a vacuum. The proposed effect, however, is very small indeed: the photons can exceed Einstein’s limit by only one part in 1036. K.
What happens to a photon when it stops?
When photons of that energy meet an atom, they can scatter and excite it to a higher level, thus the photon is absorbed and “dies”.
What does a photon actually look like?
A photon just looks like a blink of light from a small point. So, when you see a photon (if your eyes are sensitive enough), you see a blip of light. The “size” of a photon is much weirder since photons aren’t “particles” in the traditional macroscopic sense of the word.
