 00:43: Like the speed of light, the gravitational constant, or Planck’s constant.
 11:33: ... gravitational constant is the relationship between mass, distance, and gravitational ...


20220504: Space DOES NOT Expand Everywhere
 10:52: ... Planck length stays the same  it’s just defined as a combination of the Gravitational constant, the Planck constant, and the speed of light  so if those aren’t ...


20210616: Can Space Be Infinitely Divided?
 06:39: ... by a factor equal to the effective mass times the gravitational constant divided by c^2. Let’s replace the mass with the ...


20200728: What is a Theory of Everything: Livestream
