We hear a lot on the "Dark Matter" subject. But I must confess that I have yet to see any good arguments explaining just WHY "Dark Matter" avoids the visible...

I have claimed in several recent newsgroup posts, and elsewhere, that there is credible evidence that the dubious marriage of theoretical particle physics and...

I assume for now that there are so many they can't publish fast enough, but enough time has passed to be able to detect Mercury-like planets with 90 day...

As a layman, I get the gist of the Big Bang theory, and it makes sense. Here's my confusion: I've heard some scientists say that the bang was a singularity...

Can anyone point me at any experiments to determine wave evolution of quantum particles in a gravitational field. E.g. something like a Pound Rebka experiment...

There are now new observations independent from the Ia-supernovae luminosities supporting the concept of an accelerated expamsion of our universe. Wouldn't...

Can the "standard model of cosmology" or the "standard model of particle physics" make a definitive prediction regarding the dark matter, which constitutes...

If dark matter exists, it should be accreting into the black holes at the center of each galaxy. Now, X. Hernandez ad William H Lee, explore the question and...
