It is not the weight that is relevant, but the mass. And when it is stated that a photon has no mass, that refers to its "rest mass" or "invariant mass". But since it has energy, it certainly has an equivalent mass as well - all energy has mass. In any case, what actually happens here is that the black hole distorts space and time around it in such a way that light will no longer go in a straight line (in the traditional sense); once it gets within the event horizon, a photon can only get deeper into the black hole, no matter in what direction it moves.

What can happen to photons approaching a black hole?

Light that passes near a black hole but does not cross the event horizon is bent toward it in what is called gravitational lensing. The closer the light passes to the black hole, the more it is bent. For someone with an up-close view, this lensing would result in a highly distorted image of whatever is behind the black hole. Photons that cross the event horizon are lost inside of it forever, and their energy is added to the mass of the black hole.


Why don't the weight of a black hole tear space time?

First, it isn't the "weight", but the mass of the black hole that is relevant. Second, the black hole does, indeed, greatly distort space and time in its neighborhood.


Why is light attracted to a black hole?

Light is not only attracted to a black hole, in fact, its attracted to you, to me and to everything made of matter in the universe. The problem is that light is affected by gravity, and the black holes have so much that light significantly change trajectory or the black holes absorb the photons


What would be your weight in deep space and near a black hole?

Your "weight" is the magnitude of the gravitational force between you and another mass. -- In deep space, far from any other mass, the gravitational force between you and any other mass would be very small, but never zero. -- Near a back hole, the gravitational force between you and the black hole would be (gravitational constant) x (your mass) x (black hole's mass)/(your distance from the black hole)2


Do black holes give off radio waves?

Black Holes don't give off radio waves. They emit X-rays. This happens rarely since the black hole's gravity is so strong that it doesn't allow photons to escape.

Could the theory of dormant black holes truly exist if a black hole isn't sucking in matter that it musnt be rotating if it isn't rotating how could it even exist?

The rotation is not related to the black hole's ability to attract matter. The attraction depends only on the black hole's mass.The rotation is not related to the black hole's ability to attract matter.

Why doesn't the black hole have light?

You 'see' things when light (photons) are reflected off a surface, and absorbed by your retina. A black hole's gravitational field is so strong, that the escape velocity exceeds the speed of light. Any photons within a certain radius will be unable to escape. Since no photons are being emitted, the black hole appears black and gives off no light.


Is black hole attract every object in universe?

If one of a pair of entangled photons is drawn into a black hole than what is the result to the other?

Photons do not become "entangled" with each other any more than waves on water do. They move along independently. If a photon crosses the event horizon of a black hole as that photon follows the curve of spacetime "down" into the black hole, it is probable that a photon moving "with" it will suffer the same fate.

How light attracted by black hole even light has no weight?

According to the general theory of relativity, gravity does not attract; instead gravity bends spacetime. Objects always follow locally straight lines of motion, but in bent spacetime a locally straight line of motion is not globally straight, instead it is globally bent. Thus it does not matter if an object passing near a black hole has mass or not, its path will bend toward the black hole. Note: do not confuse mass and weight. In free fall all objects, whether they have mass or not, have no weight.


How can black holes suck you up?

A black hole will attract you through its gravity - just like any other object will.


If light can be pulled into a black hole that suggests mass What is the weight per square meter?

light has no mass and therefore no weight. Light cannot be "pulled" into a black hole. The escape velocity from a black hole is greater than the speed of light, so no light can escape from a black hole. Spacetime in the vicinity of a black hole is greatly distorted by the hole's gravity, and light may travel along curved geodesics that intersect the black hole. But it is not pulled in.
