The whole point of an explanation is to reduce something you don't know to something you do. By that standard, you don't gain much by explaining anything in terms of black holes.
In chatting with colleagues after a talk this week, Joe Polchinski said he'd love to fall into a black hole. Most theoretical physicists would. It's not because they have some peculiar death wish or because science funding prospects are so dark these days...
For years I've been thinking and hoping that quantum physics would become the next hacker revolution. DIYers in their basements, garages, and hackerspaces have already pioneered radio communications, PCs, household robots, and cheap 3-D printers--why not quantum entanglement, cryptography, computers, and teleportation?...
In about 10 minutes, using stuff you probably already have lying around your house, you can watch atomic nuclei and elementary particles for yourself using a diffusion cloud chamber--a rudimentary particle detector...
Cosmologists have been thinking for years that our universe might be just one bubble amid countless bubbles floating in a formless void. And when they say “countless,” they really mean it...
Someone once asked me to describe string theory in 26 seconds, so, a couple of months ago, I went down to Goleta Beach with my iPhone and recorded this little video.
Last Thursday, my colleague John Matson described a truly amazing galaxy known, somewhat unromantically, as BX442. It has a majestic spiral pattern while hundreds of its galactic contemporaries were gawky and misshapen a peculiar and special anomaly which suggests to many astronomers that cosmic pinwheels are ephemeral art forms, like Tibetan sand mandalas...
It may well have been the liveliest hour and a half I’ve ever spent in the company of theoretical physicists. In April, during a workshop I was attending on black holes, Bill Unruh gave a talk that challenged his colleagues on a point almost all of them thought had been settled in the mid-1980s...
I’d heard of quantum dice, quantum poker, quantum roulette, and even quantum Russian roulette, but a quantum horse race? I learned about this surreal game of chance last December during a symposium at the Centre for Quantum Technologies in Singapore...
