Beer of the Week

The beer: Pounder Pils

Brewed by: Heavy Seas Beer, Baltimore, Maryland

Description (from the website): "Made with German malts and an plethora of European hops, Pounder Pils is an American interpretation of a classic European Style. Exhibiting a crisp malt backbone and an herbaceous hop profile, this Pilsner is quaffable and refreshing. This year-round offering is smooth and elegant showcasing a bright yet zesty botanical aroma. Named for the weight of their shot, the most common naval cannons were called 'six pounders.' At Heavy Seas, that means a six-pack of crisp, clean Pounder Pils."

Would I buy it again?: Yes. As a beer, it wasn't particularly remarkable, but the value was excellent. It cost a dollar less than most six-packs, and you get a pint instead of 12 ounces. So it gets a pass for that.

Alternate Theories to Relativity Have Not Had a Good Time Lately

It's a conundrum at the very heart of theoretical physics. We know quantum mechanics to be correct. It's how nature works at very small scales. We know that the theory of general relativity is completely incompatible with quantum mechanics. The two just don't go together. Therefore general relativity must be wrong, or at minimum, incomplete. Yet general relativity has been proven to work time and time again. But general relativity also means that dark matter and dark energy must be a thing. And despite our best efforts, we're no closer to discovering either than when we first started looking for them. Not really. And I think you get the idea at this point. It's a mess.

So, what are physicists to do? If you guessed make wild theories that somehow work in what we know about gravity AND what we know about quantum mechanics, and hope the two go together, then congratulations! You've got what it takes to be a theoretical physicist. Turns out there are lots of alternate theories of gravity out. Well, there were. The discovery of gravitational waves by LIGO killed most of them. Okay, it wasn't just that, it was that and the simultaneous observation of a gamma-ray burst from the same neutron star collision.

I think the biggest takeaway from this story is that science is always in motion. General relativity's been around for a century now, and it's been observationally validated many, many times. But it isn't perfect. And so, rather than shrug our shoulders and say "close enough", we keep going, and we try to find something that does work. There is always more science to do, always more questions to answer.
