coincidence Definition and 57 Threads

Have you ever thought why the ratio between the vacuum energy and dark energy, the total entropy of the observable universe and the squared ratio between the universe age and Planck time are all of them ca. 10^121, perhaps the biggest natural number with a physical significance? Any comments...

Coincidence of Universe age in $\Lambda$CDM and Milne cosmologies I wonder why... Just another example of the degeneracy* perhaps? Garth (*Now accepted for publication in Astrophysics and Space Science)

EK = mv^2 energy kinetic = mass times velocity squared So... Isn't one way to interpret time dilation that everything moves through time and space with a sum velocity of c (somehow), and that as velocity in space increases velocity in time therefore decreases? I've read this in several...

Some my puzzles of “coincidence counting” When I read literatures concerning with two-photon interference experiment, the “two-photon interference patterns” are always got by means of so called” coincidence counting”. My questions are: What is the coincidence counting? What the essential is the...

Our sun eminates electromagnetic radiation over an enormous range of frequencies. Radiation curves (energy@wavelength) resemble bell curves, and highly accurate measurements have shown that the peak of the sun's radiation curve is in the visible light range. This is not a coincidence, it is...

I have met people who believe magic of mathematical coincidences magnified by their own predisposition for patterning. A TV commercial will say the word "soap" simultaneously to the viewer (me) thinking it. Perhaps you, at a party, were about to say the word "hippopotamus," but suppressed the...
