Time for the object or person in question stops. This does not affect the objects around which aren't travelling at that speed or the region of spacetime which is around them. A simple and possible explanation is that time is stopped for the photon, but this stays unnoticed because we are not moving at that speed and so we cannot say what is happening to the photon.

∙ 13y agoThere is really no "Why" . . . it just does. As observed from outside, the object that is approaching the speed of light gets shorter and shorter until, at the speed of light (which we think is impossible) time stops and the object attains zero length.
From inside a container approaching the speed of light, the occupants notice no difference because time is literally slowing at the same rate they and the container are.
This effect is actually noticeable in comparing the atomic clock of a person on the ground with an atomic clock in a fast jet that circles the world. When the plane lands, its clock shows that less time has passed (because the clock was running slower, even at a fraction of the speed of light) than does the clock on the ground!

Which has a larger wavelength a slow moving photon or a fast moving golf ball?
there are no slow moving photons, they move at speed of light.
What will happen if you increase the mass in light?
Photons ('particles' of light) have zero rest mass. When they move at the speed of light (the normal situation) they do have momentum due to the relativistic nature of the Universe. If we were to hypothesize light particles with mass the development of the Universe would be entirely different.
Can electrons move slower than the speed of light?
They can ONLY move slower than the speed of light.
How fast are cosmic rays?
Cosmic rays are electromagnetic energy - like light. They quite naturally travel at the speed of light, which is 299,792,458 meters per second. Note that the cited speed applies to a vaccuum. Their speed appears to be less when they are passing through air or another medium. Sorry, I believe that this is incorrect. Cosmic rays are not light consisting of photons. At least 90% of them are high energy particles that consist of protons. They may be able to move close to the speed of light, but do not travel at the speed of light.
Absorption of light by atoms of an element occurs when photons are?
absorbed by electrons that move to higher energy levels
Can an object move with speed of light?
Yes, photons do.
What is the difference between speed and light?
Speed is how fast something moves. Light is a form of energy carried by massless photons, these photons move at the speed of light, which is the fastest speed that anything in the universe can travel.
Does a photon move at the speed of light?
Yes, a photon moves at the speed of light, because photons have no mass.
Can any object move with the velocity of light?
No object that has mass when it's just sitting there on the table can move at the speed of light. Photons have zero "rest mass".
Can a neutrino be motionless?
Yes. A neutrino usually moves CLOSE to the speed of light; this means that (unlike photons, which only move at the speed of light) it is possible to have SOME observer for which it is motionless.
Are gamma rays positrons?
No, they are not.Gamma rays are photons - just like light. They are electrically neutral. They move at the speed of light. Positrons, also known as anti-electrons, have a positive charge. They move at speeds less than the speed of light.
An object moves in light speed will shred its mass?
An object that normally doesn't move at light speed (so, this doesn't include photons for example) CANNOT move at the speed of light. As it approaches the speed of light, its mass will get higher and higher (and tend towards infinity); as will the energy required to continue speeding it up.
Is that true that the more energy of a photon the bigger the mass it possesses?
No, all photons have the same mass. Photons are massless (i.e. zero). All the energy in a photon is in its momentum, but increasing its momentum does not change it speed which is always "the speed of light". All massless particles always move at the speed of light.
Do photons effect time If speed effects the time dimension and light photons move at approx 680 million mph is the time dimension effected by this speed This stupid thing won't let me use punctuation?
No, photons neither effect time nor affect time.
What is the different between light energy and energy?
Lots of differences. For example: light is a flow of electrically neutral particles (called photons), that move at the speed of light (at least, in a vacuum). Electricity is a flow of charged particles - often electrons - that move at speeds below the speed of light.
What similarities do the waves of all colours of light share?
They are all waves, they have wavelength, they all have the same speed which is the speed of light, they all consist from photons.
What is the difference between light energy and electrical energy?
Lots of differences. For example: light is a flow of electrically neutral particles (called photons), that move at the speed of light (at least, in a vacuum). Electricity is a flow of charged particles - often electrons - that move at speeds below the speed of light.
