Why doesn't light get absorbed?

Click For Summary
Light emitted by the Sun does not get absorbed back into it due to insufficient gravitational pull; the curvature of spacetime around the Sun is not strong enough to capture photons. Unlike massive objects like black holes, the Sun can only slightly bend the path of light. The Earth is attracted to the Sun because it moves slowly enough to be captured in orbit, unlike light, which travels at a much higher speed. The gravitational influence of the Sun is effective for objects moving at lower velocities or those in close proximity. Thus, while light can be influenced by gravity, it cannot be absorbed by the Sun.

If light can give off gravity, why doesn't the gravity exerted by the sun kind of. Absorb it before it can go off to Earth and other planets?

If you're asking why doesn't the light emitted by the Sun simply fall back into the Sun, it's for the same reason I can build a rocket ship so powerful that it can fly out of the solar system and away from the pull of the Earth. The gravitational pull (or really, the curvature of spacetime) isn't enough to bring a photon back into it. You need something far more massive and compact like a black hole. What the Sun can do is only really bend light passing by slightly.

Through the same process. Something needs to be going rather slowly or be very close to an object like the Sun to be caught in an orbit. The Earth is moving very slow compared to something like light.

Light, even if emitted directly off the surface of the Sun, is just going way too fast to be pulled in by the Sun.
 

Thread 'EPR revisited'

In an inertial frame of reference (IFR), there are two fixed points, A and B, which share an entangled state $$ \frac{1}{\sqrt{2}}(|0>_A|1>_B+|1>_A|0>_B) $$ At point A, a measurement is made. The state then collapses to $$ |a>_A|b>_B, \{a,b\}=\{0,1\} $$ We assume that A has the state ##|a>_A## and B has ##|b>_B## simultaneously, i.e., when their synchronized clocks both read time T However, in other inertial frames, due to the relativity of simultaneity, the moment when B has ##|b>_B##...
