Dispatches From Turtle Island

One of the first particles predicted by quantum chromodynamics (QCD), which consists of the laws of physics related to the strong force, who...

Another author has proposed a mirror universe model with an anti-universe that comes before the Big Bang where time flows in the opposite d...

Four years ago, we got the first ancient DNA from Central Africa, from the pre-Bantu population (ca. 3,000 to 8,000 years ago) of a site nea...

I think I missed this paper when it came out a couple of years ago (see also an article on it in the Smithsonian, which also links to an En...

The language map below is from just prior to the emergence of Islam ca. 600 CE, which was well after the fall of the Western Roman Empire.  ...

A new preprint rigorously derives a fairly robust lower bound on the possible mass of dark matter particles, if they exist. The new bound is...

As yet another paper lays out the path to putting final nails in the coffin of primordial black holes (PBHs) as a significant source of dark...

An upper bound on the energies of massive particles would be very important because it was set an upper bound a many kinds of high energy ph...

A recent recap paper provides the state of the art properties of the tau lepton. The tau lepton mass, previously noted in this blog post , i...

The Past Modern physics started a little more than a century ago in the early 1900s.  The state of physics immediately before that point is ...

Image from Wikipedia . The biggest meteor impact on Earth in the last 10,000 years struck Western India around 6905 BP (i.e. 4955 BCE).  The...

Figuring out how long it takes an atom to engage in quantum tunneling is very experimentally challenging, because the distances are short, t...

The "four wave" idea is that there were four waves of people in the founding population from two eras. These were in  turn followe...

Another interesting gravitational explanation of dark matter and dark energy phenomena. We argue that the effect of cold dark matter in the ...
