Physicists in Germany and the US developed an entirely new kind of particle that doesn’t exist in nature, called a dropleton.
Writing in the journal Nature, they said it behaves a bit like a liquid droplet and described it as a quasiparticle — an amalgamation of smaller types of particles.
The discovery, they added, could be useful in the development of nanotechnology, including the design of optoelectronic devices. These include things like the semiconductor lasers used in Blu-ray disc players.
The microscopic quantum droplet does not dawdle. In the physicists’ experiments using an ultra-fast laser emitting about 100 million pulses per second, the quantum droplet appeared for only about 2.5 billionths of a second.
Ever been sitting around wondering if you could survive the impact of meteorite the size of your house if it landed in the next town over? I know I have. Time to bring the science. Purdue University’s interactive tool has its drawbacks, and it’s more data driven than visual, but it’s still fun.
Conventional thinking has it that the universe and all the matter within it exploded out from a single point, the so-called Big Bang Singularity. But a German theoretical physicists says this never happened. Instead, the universe started empty and cold, slowly emerging from a deep freeze.
Even though ball lightning has been reported for forever, scientists have never really been able to get any good hold on exactly what it is. It doesn’t show up anywhere or under any particular conditions predictably, making finding and studying the phenomenon incredibly difficult. Recently, a group of Chinese scientists just happened to be in the exact right place at the exact right time with exactly the right equipment, and it turns out ball lightning isn’t something alien— it’s dirt. Hot dirt.
At least not “black holes” as they’re currently defined, where there’s an even horizon, a point at which light or nothing else can escape once it gets sucked in. While his paper has not been peer reviewed, what he’s essentially saying is that because of quantum fluctuation, stuff can and does escape from black holes, which basically just takes the “black” out of black holes. Everyone could just say “Stephen Hawking says things can escape from a black hole”, but instead, it sounds a lot better to say “there are no black holes”.
You might have already imagined that electrons are perfectly round, and the ancient Greeks would have, too. Scientists at Yale and Harvard thought otherwise, assuming electrons had a bit of lumpiness to them, with the inconsistency owing to undiscovered particles of dark matter. So when it turned out that electrons are absolutely, perfectly round, that became a problem, because it’s further evidence towards a major flaw in the Standard Model, but we don’t know what.
39 minutes. It may not seem like a lot, and obviously compared to the computer you’re reading this on, working for 39 minutes sounds kinda lousy. But in terms of quantum computing, it’s a big, big, big deal. That’s how long scientists were able to hold a qubit’s memory state for, which is way longer than anyone had previously been able to accomplish.
