Pneumonic plague is a severe lung infection caused by the bacterium Yersinia pestis. Symptoms include fever, headache, shortness of breath, chest pain, coughing, and coughing up blood. It is airborne and if not treated quickly, nearly 100 percent fatal.

The timescape hypothesis, proposed by David Wiltshire, argues that the expansion of the universe is NOT accelerating, as many physicists believe. This "acceleration" is based on an illusion: that matter is distributed evenly through all of space and that time passes at the same rate everywhere.

Theoretical physicists have explored many speculative ideas to explain how our universe works. The current rage is holography, which suggests that the physical world we live in is not real—it's just a projection of information imprinted on the surface that bounds our universe. #cosmology

On this day in 1962, Alouette 1 was launched. It was the first Canadian satellite, and the first satellite not constructed by the USA or Soviet Union. Launched to investigate the ionosphere, the mission lasted for 10 years but the satellite will remain in orbit for 1000 years.

Do gravitational waves show evidence of wave-particle duality? If they did, we would have evidence for a quantum theory of gravity. Our current instruments can detect gravitational waves, but finding those hypothetical particles, dubbed gravitons, is a much more difficult challenge.

All matter particles can act as waves, and massless light waves show particle-like behavior. Can gravitational waves also be particle-like?
