Can a massless object experience time?
Massless objects do have affine parameters, but they are not proper time. It is true that photons do not experience proper time. On the other hand a photon can experience a series of events during its lifetime.
Why do photons not experience time?
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.
Why do you need mass to experience time?
The nature of the relation is inverse in that higher mass energy corresponds to shorter cycles of less time more frequently. Instead of mass energy clocking time forward, it delays signals dragging time so that everything does not happen at once. The more mass there is, the more hysteresis there is in spacetime.
How does gravity affect massless particles?
Massless particles are known to experience the same gravitational acceleration as other particles (which provides empirical evidence for the equivalence principle) because they do have relativistic mass, which is what acts as the gravity charge.
Why are massless photons affected by gravity?
Matter and energy curve spacetime, and curved spacetime tell both matter and energy how to move. That’s why masses can exert a gravitational influence on photons: they curve space. The photon has no choice of what it needs to do.
Do electrons experience time?
Yes. So they gain mass and experience time dilation at near light speed.
Why do massless objects travel at c?
But an object with zero energy and zero mass is nothing at all. Therefore, if an object with no mass is to physically exist, it can never be at rest. But light is not the only massless object. Gluons and the hypothetical gravitons are also massless, and therefore travel at speed c in all frames.
How does mass relate to time?
Time never depends on mass. Time is an independent quantity, and so is mass. But it is true that time curves around bodies of mass. So the greater the rest mass, greater the curvature of time, which implies that time flows slowly around heavier objects.
Does mass have an effect on time?
The bigger the mass,the slower time gets around it. Because when gravity affects an object, his space-time is being curved by the mass of the one who provocates gravity. So, if time and space are being curved, the distance the object has to travel is longer, so it’s his time.
Do massless objects experience gravity?
How does light experience time in massless particles?
Massless particles are four-dimensional packets of waves that travel in the same spacetime continuum ( they are distorting just a single spacetime continuum) at the maximum speed allowed by the Observable Universe. So, how does light experience time? We know that there is time dilation and there is time contraction, also.
Why do massless particles have more momentum than massive particles?
This is because the momentum of a massless particle depends only on frequency and direction, while the momentum of low speed massive objects depends on mass, speed, and direction (see energy–momentum relation). Massless particles move in straight lines in spacetime, called geodesics, and gravitational lensing relies on spacetime curvature.
What are massless particles?
Massless particle. In particle physics, a massless particle is an elementary particle whose invariant mass is zero. The two known massless particles are both gauge bosons: the photon (carrier of electromagnetism) and the gluon (carrier of the strong force). However, gluons are never observed as free particles, since they are confined within hadrons.
Why do massless particles move in straight lines in space?
This is because the momentum of a massless particle depends only on frequency and direction, while the momentum of low speed massive objects depends on mass, speed, and direction. Massless particles move in straight lines in spacetime, called geodesics, and gravitational lensing relies on spacetime curvature.
