Thank you for your reply. According to my calculations, the acceleration would have to be infinite which would require an infinite mass. See my paper here. <personal theory link deleted>

Acceleration due to gravity at the Event Horizon of a Black Hole.

Rest mass Correct me if I am wrong but I don't think that there is such a thing as a photon which is at rest. The instant a photon is created it reaches the speed of light. Incidentally, from the photons perspective, the instant it is created, it is destroyed (according to special relativity)...

Reply to DrewD I do have a physics background. I do not however claim to know everything. I made the post to stimulate conversation on existing theories which may or may not be correct. One person behaving as if he has all the answers and disrespecting everyone else does not help.

momentum Momentum is mass times velocity. No mass, no momentum.

If the mass of a photon is zero, the proton drive idea for rocket propulsion would not work. (Newton's third law).

potential energy To say that a mass m1 of a distance d from another mass m2 has potential energy was always the way it was taught in my physics class. However this seems a bit of a cop out. If a mass is created somewhere in the universe, what is its potential energy? You would have to...

I have heard that photons do not have any mass which is why they travel at the speed of light. However consider the following thought experiment. You are box in space accelerating at 1 G. From your perspective, you are in a gravitational field of 1G. If you shine a light from one wall of the...

Gravity can be considered a form of radiation which travels through space at the seed of light. If the sun suddenly disappeared, we would continue in orbit around it for approximately 8 minutes before we continued through space in a straight line. However, to call it radiation seems to me to be...

General relativity shows that gravity is a culture of space time. Suppose that we are in a gravitational field. This can be caused by the presence of matter or being in an accelerating frame of reference. In either case, it is possible to select another accelerating frame of reference for which...

Supposing we have two objects of masses m1 and m2 repeated by a large distance and sufficiently distant from any other masses or gravitational fields. The masses are not moving relative to each other initially. The masses will eventually move together by their mutual gravitational...

You are absolutely right. A black hole can would take an infinite amount of time as measured by the clock of an outside observer to fall through its own emerging event horizon and thus can never form. It is hardly surprising that the physics does not make sense inside a black hole. These things...
