Light is bent as it travels because it is impacted by the large masses (planets and stars) that it bypasses. Most noticeable over long distances (like billions of miles).

Actually, gravity does not affect light *directly*. It bends space which is where light travels. Light does not escape a black hole because the gravity pulls the light in, but because gravity makes the distance infinitely long for the light to travel.
On earth, the gravity gradient is low enough that it barely affects the curvature of space (but it does, everything with a mass curves space). And that bending of space affects everything, not just only light.

The gravity is so great that most parameters are changed. Light has no mass and space is mostly empty so there is no loss in light travel. The gravity or black hole can be as big as 100 light years across. Very near the black hole it is conceived that even time is warped.

Per Einstein's theory of general relativity, objects with mass tend to curve space around them. The greater the mass, the more severe the curvature. We know this curving as gravity.
Light has no mass. It is not attracted to other objects. It does however travel in a straight line, or tries to. In the presence of gravity, a straight line becomes curved, so a ray of light tends to bend.
In the case of a black hole, the curvature of space is so severe that a beam of light passing too close will find itself wrapped around in a circle. Thus it will never escape. So it isn't actually "sucking" on the light; it's distorting the fabric of space-time such that photons that go in don't come out again.

yes, light is made of particles, and thus it is affected by gravity. Because it travels at an enourmous speed, the effects of planets are fairly negligable, but existant. The light passes the event horizon before the gravity can have much effect on it.
The more massive an object is, the more gravity it has. Because of the enourmous mass of the black hole, the light particles can not travel fast enough to escape.

Gravity would not advance up easy (photons constantly strikes on the fee of sunshine and haven't any mass), even though it does bend area-time so as that the "quickly-line" process sunshine (called a geodesic, and representing the shortest course between 2 factors) is bent to examine. A black hollow curves area-time sufficient that each physique geodesics interior the form horizon are bent to stay interior the horizon, so no easy can get away. easy interior the form horizon continues to be shifting on the fee of sunshine, purely no longer attaining an outdoors observer. there is not any "% at which era slows down." An observer finding at any merchandise that's shifting or accelerating relative to the observer will see relativistic time differences. We see this in watching GPS satellites from Earth (regardless of if we are seeing the two the effects of orbital and gravitational acceleration alterations). we are able to additionally degree the time substitute making use of a severe-% plane or rocket with an atomic clock.

We don't "feel" it, because our gravity is so weak that it affects light negligibly (almost not at all).
When we observe "lensing" (where light is bent by stars), the effect is fairly small, the light is often bent only a few degrees. That is a STAR doing the bending. The earth has about 3330,000 times less mass than our sun which is not that big as far as stars go.
It's like seeing a tornado destroy a town and saying "we have wind here, why don't we see that happening?" when you are talking about summer breezes.

This page below should explain all.
Light is a form of energy, in particular, a form of electromagnetic energy. Light is intimately related to the electromagnetic force. The presence of light makes charged particles accelerate, and the acceleration of charged particles makes light.
How do we characterize light? Light comes in little packets called photons. Each of these can be thought of as a little wave which moves through space. Like any waves, you can characterize light waves with a wavelength, a frequency, a speed, and an energy. Light waves come in all different wavelengths. However, all wavelengths travel at the same speed, the so-called speed of light. In addition, the energy of each photon is also related to the wavelength. Photons with shorter wavelengths have more energy than those with longer wavelengths.

Gravity pressure is greater on small masses than on large mass structures.
Light being the smallest mass structure would be subject to the greatest gravity pressure.
Micromasses moving toward large and dense masses would be subject to accelerate towards them.Light is the smallest micromass of the Universe.
