Yeah, I would agree that the Planck length is not the most relevant thing for this subject, but it did helped me find other values later on. When I started to think about that problem, I started to think about the Planck length and wanted to see if it was related to special relativity, then I though it might have a link to gravity and so on... I tried to solve this on my own, but I think I still have a little bit more to learn

If the cosmic rays are high energy subatomic particle, my calculations should be the same because those particles have mass. But if it's a high energy electromagnetic wave, then it would just follow the geodesic of space time. My problem only occur when the object in the gravitational field has mass

If Newton's equation are not wrong, is there a way to find the velocity of the ball at any given distance from the black hole (from the point of view of an observer infinitely far away from the black hole)? What would I do differently in my calculation to find the velocity of the ball?

I have a question about Newton's equation for gravity. What would happen if you threw a ball with an initial velocity very close to the speed of light towards a black hole. We would assume that you would be very far from the black hole. Would the ball accelerate pass the speed of light before it reaches the event horizon? I did some calculation and found that the ball will indeed surpass the speed of light far before reaching the event horizon. Does this mean that F=GMm/r^2 is wrong because it breaks special relativity? I did found a solution on my own but I'm not even sure if it's right. I put the calculations and my solution to the problem on a word document, so if anyone is curious to see what I did, you can look at the word document. Is Newton's equation for gravity wrong.docx
