Walkabout the Galaxy
extrasolar planetary zoo, Neptune, NASA's return to the Moon
Astrophysics and Astronomy | Physics
The astroquarks take a stroll through the extrasolar planetary zoo where there are new members of the close-to-Earth-sized club and a peculiar Neptune-y thingy orbiting super close to its star. Meanwhile there are rapid developments in NASA's renewed focus on sending astronauts to the Moon, and we revisit the strange case of quarks, anti-quarks, and the existence of matter in the universe. Plus a very deep dive into Forbidden Planet-inspired trivia.
The Riemann Hypothesis
Ever find yourself wondering what the real part of a non-trivial zero of the Riemann zeta function is? Who hasn't?! If you had a nickel for every term in the zeta function, well then you'd be infinitely rich. The Riemann Hypothesis can't make you money – unless you prove it, in which case you're going to get a $1 million! But in the meantime, take it from the Riemann Hypothesis: the answer is one-half. Zero point 5. 50 per cent. One over two. Let's see the Birch and Swinnerton-Dyer Conjecture come up with an answer that easy! The Riemann Hypothesis: It is… Are you?
