Neil deGrasse Tyson at 85% the Speed of Light
This video made me laugh harder than anything I’ve seen in a long time. Okay, except for some Louis CK videos. But for a non-comedian (allegedly)… this is hard to beat.

“The Perfect Theory”: The story of general relativity, and what makes something a science
Pedro Ferreira’s book “The Perfect Theory: A Century of Geniuses and the Battle over General Relativity” essentially tells us what other people did with Einstein’s general theory of relativity after he developed it.
Fun with Gravitational Waves
Even the Earth–sun system radiates gravitational waves, but just how powerful are they?
Spacetime Ripples and the Human Condition
Our species just stepped into a cosmic future, yet we still starve and fight each other
Just How Resilient Is Spacetime?
A hundred years on, and the implications of Einstein's general relativity still surprise and delight

100 Years of Great Physics: Watch Live Monday and Tuesday [Video]
General relativity and Noether’s theorem take center stage in two live Web broadcasts this week
Stephen Hawking's New Black-Hole Paper, Translated: An Interview with Co-Author Andrew Strominger
The Harvard physicist explains the collaboration's long-awaited research on the black-hole information paradox
Using Causality to Solve the Puzzle of Quantum Spacetime
A new approach to the decades-old problem of quantum gravity goes back to basics and shows how the building blocks of space and time pull themselves together
A Quantum Threat to Special Relativity
Entanglement, like many quantum effects, violates some of our deepest intuitions about the world. It may also undermine Einstein's special theory of relativity
Was Einstein Wrong?: A Quantum Threat to Special Relativity
Entanglement, like many quantum effects, violates some of our deepest intuitions about the world. It may also undermine Einstein's special theory of relativity
Do Naked Singularities Break the Rules of Physics?
The black hole has a troublesome sibling, the naked singularity. Physicists have long thought--hoped--it could never exist. But could it?
The Utter Failure of Fictional Time Travel
An answer to why we’ve not been visited from the future?
To Catch a Black Hole, Use a Black Hole
Astronomers exploit a remarkable supermassive black hole binary system to measure the primary black hole's spin
Merging Black Holes: A Matter of Some Gravity
Two black holes merging can cast off a few percent of their total mass as gravitational waves in just minutes, sending the final object off on a high-speed journey through the universe
Krugman’s Theory of Interstellar Trade
Everyone needs a little light relief sometimes, including the Nobel winning economist and writer/blogger extraordinaire Paul Krugman. A few months back he reminded the world of a short paper he’d written some years ago on the rather unexpected topic of interstellar finance.
Hope for a New Particle Fizzles at the LHC
A curious signal of a potentially revolutionary new particle detected last year turned out to be a fluke
Darwin's Living Legacy--Evolutionary Theory 150 Years Later
A Victorian amateur undertook a lifetime pursuit of slow, meticulous observation and thought about the natural world, producing a theory 150 years ago that still drives the contemporary scientific agenda
