The Cosmological and Fine-Structure Constants

Physicist David Goodstein, and astrophysicists Neil deGrasse Tyson and Roger Blandford briefly discuss the renewed interest in Einstein's cosmological constant, as well as recent evidence that the fine-structure constant might actually be changing.

Umm... if the 'fine-structure constant' is changing, doesn't that mean it's NOT a constant?

[LennyBound]

Yeah...

Lenny Bound, ur a gift

[Elungtrings]

Thumbs up for the idea Neil deGrasse Tyson has at the end there.

@mdma4life Stop! Dont be foolish! Your mom didnt create the Universe! We have to be real about this. We all know Chuck Norris did it......

@Bardoftoday

My mom created the universe, deal with it

Thinking about the changing of the fine structure constant I wonder about the effect on the number of elements in the periodic table, and how they came about, variations and mutations in evolution, and many other things that depend on the electron as well as how this reflects upon the big bang theory and the expanding universe, can't wait to hear more about this

Not only is the constant changing, it also has an axis, the alpha reading is much larger when viewing objects (distant quasars) in the southern hemisphere than in the northern. J.K Webb discovered this a few months ago

the only thing that is eternal is God, who created the universe

Whitehead would have loved to hear this. No laws, only habits.
