Why is there something rather than nothing? Well the answer may be found in the weakest particle in the universe: the neutrino. For over half a century Fermilab has been the premier particle accelerator facility of the United States and we got to visit with Don Lincoln to explore it’s science and its engineering. These days many of the super-powered geniuses of Fermilab are tackling the mysteries of the neutrino. Why? Because this elusive particle may hold powerful secrets: from the unification of the forces of nature to the biggest question of all: why is there something rather than nothing?

Black holes are awesome - but how about black holes being captured by the screaming vortex of a quasar, where they merge and grow like some monstrous version of a solar system. This insane hypothesis is getting closer to reality, according to the papers in today’s space time journal club.

The three body problem is famous for being impossible to solve. But actually it's been solved many times, and in ingenious ways. Some of those solutions are incredibly useful, and some are incredibly bizarre.

In particle physics we try to understand reality by looking for smaller and smaller building blocks. But what if that has been the wrong philosophy all along?

If the universe goes on forever, does that mean there are infinite versions of you out there?
