“These neutrino observations are so exciting and significant that I think we’re about to see the birth of an entirely new branch of astronomy: neutrino astronomy.” -John Bahcall You’ve been around here long enough to know about the Big Bang. The vast majority of galaxies are speeding away from us, but more than that, the…

“It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing — a somewhat unfamiliar conception for the average mind.” -Albert Einstein You’ve heard and seen it plenty of times: Einstein’s most famous equation, E = mc2. I’ve taken you inside this equation before, which…

“God put me on this earth to accomplish a certain number of things. Right now I am so far behind that I will never die.” -Bill Watterson Welcome back to another Messier Monday, only here on Starts With A Bang! With each new Monday, we take an in-depth look at a prominently visible random object from Messier’s catalogue…

“Other than the laws of physics, rules have never really worked out for me.” -Craig Ferguson Earlier this week, evidence was presented measuring a very rare decay rate — albeit not incredibly precisely — which point towards the Standard Model being it as far as new particles accessible to colliders (such as the LHC) go.…

“We knew that we had indeed done something that was very different and very exciting, but we still didn’t expect it to have something to do with physical reality.” -Gerald Guralnik, co-developer of the Higgs mechanism Might as well make this entire week “Higgs week” here on Starts With A Bang, given how important yesterday’s…

“This is evidently a discovery of a new particle. If anybody claims otherwise you can tell them they have lost connection with reality.” -Tommaso Dorigo You’ve probably heard the news by now: the Higgs boson — the last undiscovered fundamental particle of nature — has been found. Indeed the news reports just keep rolling in;…

“Everyone must leave something behind when he dies, my grandfather said. A child or a book or a painting or a house or a wall built or a pair of shoes made. Or a garden planted. Something your hand touched some way so your soul has somewhere to go when you die, and when people…

Big News about Black Holes!

This has been all over my inbox since the press release came out yesterday; it’s been on slashdot (thanks Brian), it’s been at space.com, and there’s a mediocre writeup on Universe Today. What’s the big news? Black Holes don’t destroy information after all! What is this whole information thing, anyway? Take a look at all…

Avoiding Armageddon!

Let’s say we’re having a nice day here on Earth; the Sun is shining, the clouds are sparse, and everything is just looking like a peach: And then Lucas goes and tells me, Oh my God, Ethan! It’s Armageddon! An asteroid is coming straight for us! You’ve got to stop it! Really? Me? Well, how…

The Story of Neptune

(This is adapted from my public lecture, Afraid of the Dark: How We Know What We Can’t See.) Let’s go back over 200 years ago, to 1781. William Herschel (left) discovered the planet Uranus, noticing that an object, as bright as a star, was actually moving relative to the other stars. The other five inner…
