For John, BLUF: It is like COVID-19. One suspects we are a ways yet from knowing ground truth. Nothing to see here; just move along.
Here is the sub-headline:
From the Blog Site Watts Up With That, by Mr Charles Rotter, 28 April 2020.
Here is the lede plus three:
University of New South WalesFrom the Party of Science I gEt the impression that they think science is all settled. From the Party of Engineering I am not so sure they believe the science is settled.
Those looking forward to a day when science’s Grand Unifying Theory of Everything could be worn on a t-shirt may have to wait a little longer as astrophysicists continue to find hints that one of the cosmological constants is not so constant after all.
In a paper published in prestigious journal Science Advances, scientists from UNSW Sydney reported that four new measurements of light emitted from a quasar 13 billion light years away reaffirm past studies that have measured tiny variations in the fine structure constant.
UNSW Science’s Professor John Webb says the fine structure constant is a measure of electromagnetism – one of the four fundamental forces in nature (the others are gravity, weak nuclear force and strong nuclear force).
