2022-09-28: Why Is 1/137 One of the Greatest Unsolved Problems In Physics?

  • 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 ...

2022-05-04: 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 ...

2021-06-16: 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 ...

2020-07-28: What is a Theory of Everything: Livestream

  • 00:00: ... take the basic uh constants of nature uh you know planck's constant gravitational constant speed of light things like this these numbers that just sort of ...

2020-05-27: Does Gravity Require Extra Dimensions?

  • 00:00: It’s been 120 years since Henry Cavendish measured the gravitational constant with a pair of lead balls suspended by a wire.
  • 08:55: ... off the amount of rotation Cavendish made the first measurement of the gravitational constant. ...
  • 09:34: The meticulous care paid off—Cavendish measured a gravitational constant that agrees with our modern value, with 1% uncertainty.

2020-02-18: Does Consciousness Influence Quantum Mechanics?

  • 15:49: ... like the speed of light and the gravitational constant are just scaling factors and so varying them shouldn't lead to quantum ...

2017-09-28: Are the Fundamental Constants Changing?

  • 03:11: The dimensions behind, say, Newton's gravitational constant-- or the mass of the electron-- all have arbitrary human definitions.

2017-01-19: The Phantom Singularity

  • 06:30: In fact, it's 2 times the gravitational constant times the mass.

2017-01-11: The EM Drive: Fact or Fantasy?

  • 04:14: It's the same tool that Henry Cavendish used to first measure the teensy tiny gravitational constant over 200 years ago.
