1. In Leonard Susskind’s “The Black Hole War,” he says that if radiation has a wavelength larger than the event horizon of a black hole, it will bounce off instead of falling in. I've never read this anywhere else. Can anyone here discuss this topic further? 2. Based on how dense the energy and matter was immediately after the big bang, for how long after the big bang was the escape velocity greater than the speed of light, and thus, the entire Universe was inside the event horizon of a black hole? 3. If gravity was a repulsive force at the singularity of the big bang, why is it not repulsive at the singularity of a black hole? 4. How can a singularity be said to rotate when it has no spatial dimensions? 5. Black holes are described as having a mass, but isn’t 100% of the mass in the singularity itself, which has zero volume? If this is the case, then I think 100% of the volume of the black hole inside the event horizon would have no mass. 6. How does matter ever get to the singularity from the event horizon if time slows to a stop at the singularity? 7. What happens as a string gets close enough to a singularity to experience a time gradient severe enough to distort its vibrational wave pattern? 8. Does the speed of light have any relationship to any process that generates electromagnetic radiation? For instance, does the quantum of energy needed to create the longest wavelength radio wave equal the smallest quantum of energy released to place an electron in the lowest energy orbit? 9. Could the speed of light be a property of spacetime rather than of matter and energy? 10. If all forms of life are entropy engines, taking in low entropy energy and giving off high entropy energy and the arrow of time is the direction pointing toward greater entropy, could a living creature’s perception of time be due to their being entropy engines?
