Physics knows many constants. But how… constant are they?

Sheldrake did a research in physics books. He looked for the “constants” of nature. And was surprised to find that these “constants” changed during the years! Between 1928 and 1945 the constant of the speed of light dropped by 20 km/s. In 1948 it went up again.

Look at this interesting related research here.

Speed of light changing... (from "CERTAIN INVESTIGATIONS REGARDING VARIABLE PHYSICAL CONSTANTS" by Amritbir Singh, R. K. Mishra & Sukhjit Singh)

Sheldrake talked with the head of Metrology at the National Physical Laboratory in Teddington and the latter attributed this change to “intellectual phase-locking” of the physicists at the time! He said that “The speed couldn’t have actually dropped! It’s a constant!”. (see here how the speed of light is now said to change)

WOW!

And then when Sheldrake asked “How do you know this is not happening now as well?” and the metrologist said “Well, we know that’s not the case. We fixed the problem” – “How?” – “We fixed the speed of light by definition in 1972”. Actually they defined the meter along with the speed of light, so then the latter changes the first changes as well.

WOW again!

Surely changes in the measurements could result from changes in the technologies used to measure. However I doubt if such changes can account for the fall in c between 928 and 1945. And there are many known physicists who have thought of a changing speed of light (check out the Wikipedia article on VSL – Variable Speed of Light – or at this article here).

G also is varied by more than 1.3% in recent years. We already know it is changing throughout thet day and during the year. Sheldrake asked from metrologists to publish the raw data of G calculations from various laboratories around the world so that we can see if there is any change, since almost all laboratories measuring G get a different value… Nothing is published yet because… well.. G is a constant!

Why bother looking for changes in a “constant”?!?

See his lecture “The Science Delusion” (banned from TED) below…

UPDATE: Check here for a new “new measurement” of G.
