  1. Graviton would not need to escape from inside the event horizon. Gravitational field is present outside of it, and graviton is a quantum of that field.
  2. I'd like to know the Janus' explanation, but my guess is that to decelerate at the end, you need to accelerate that deceleration fuel in the beginning. So, you'd need about 8 kg of fuel per kg of payload for the deceleration at the end, but much more than that at the beginning.
  3. This part is not (and was not, since I've heard about this hypothesis first time) clear to me. Populations in biology are finite in size and limited by available resources, which is the cause of competition and natural selection. I don't see this kind of selection in this hypothesis.
  4. This is the only number of dimensions that makes equal the numbers of independent rotations and independent boosts, for example.
  5. I, OTOH, am unclear how values of parameters can be without a dynamic cause.
  6. We start with eliminating some of them. Speed of light, Planck's constant, gravitational constant, and Boltzmann constant are just unit conversion factors. They are all equal 1 in appropriate units. (Re @TheVat's post above)
  7. I think it can be refuted in principle, for example, if ways to derive the values of constants from first principles were found.
  8. I think it's an exaggeration. They are different in many respects. Perhaps, there were other forms, different, mixed, and intermediate, that did not survive for us to know them.
  9. Free will or Predestined Both.
  10. If the OP in this thread, https://www.scienceforums.net/topic/127224-artificial-consciousness-is-impossible/, were correct then consciousness would be such a characteristic. (Just a note, no need to discuss.)
  11. Here is another way. The distance to the Sun and its angular size let you find its diameter. Now you have two unknowns, the distance to the Moon and its diameter. You need two equations. The picture gives you one equation based on the equal angular sizes of the Sun and the Moon. If you can measure the time between the Moon touching the Sun and the moment in the picture, it gives you time that takes the Moon to move the distance equal to its diameter. We know how long it takes the Moon to move the entire length of its orbit around the Earth. Comparing these two times gives you the second equation. Then you solve two equations with two unknowns.
  12. Can you provide something in writing? I can't discuss a video, and also the forum rules require so.
  13. Sun diameter = 1.392x10^6 km Moon diameter = 3475 km Earth to Moon distance = 152036000 / 1.392x10^6 * 3475 = 380000 km
  14. The current state of affairs: Decades-long bet on consciousness ends — and it’s philosopher 1, neuroscientist 0 (nature.com)
  15. I was not responding to you.
  16. To me, the presence of vestigial structures and genes is strong evidence of no design.
  17. Another project to fight macroalgae in order to help corals: Florida’s coral reef is in crisis. These crabs can help. - Vox
  18. Thus, in a roundabout way this story fits very well this thread. Thank you.
  19. Lord Kelvin - Wikipedia disagrees: The "Two clouds" speech:
  20. The physicist–philosopher Ernst Mach (1838–1916), who spoke of “the artificial hypothetical atoms of chemistry and physics,” never accepted their existence. As late as 1916, shortly before his death, he declared that “I can accept the theory of relativity as little as I can accept the existence of atoms and other such dogmas.” This goes to show that a scientist can maintain his own principles, bravely holding out against a wide consensus of the scientific establishment, and still be wrong. Weinberg, Steven. Foundations of Modern Physics (p. 58).
