Only So Many Noises

Ricky can laugh it up about the UFO magazine and the horse in the pub, but Karl is correct that there are only so many noises that can occur. The piano keyboard analogy is actually kind of brilliant. Where Karl gets it wrong is his estimate that all noises have been used five times. More […]

Perpetual Motion?

Starts out sounding pretty exciting… Time crystals could behave almost like perpetual motion machines As every young science student knows, moving objects have kinetic energy. But just how much energy does something need to move? In a new study, a pair of physicists has shown that it’s theoretically possible for a system in its lowest […]

If It's True…

…if it’s really been established that some particles are traveling faster than light — and I very much doubt that that’s the case — then how much of the rest what Einstein had to tell us about the workings of the universe still holds? Specifically, are these particles actually traveling backward in time? I mean, isn’t that […]

Testing the Many-Worlds Interpretation

Tipler says its doable: The many worlds interpretation of quantum mechanics holds that before a measurement is made, identical copies of the observer exist in parallel universes and that all possible results of a measurement actually take place in these universes. Until now there has been no way to distinguish between this and the Born […]

Kathy on the LHC

Speculist contributor Kathy Hanson (who also blogs at Beyond Words) has been involved in the long, slow process of selling out to the mainstream media over the past few years. Stephen and I totally approve of this, of course, as we are constantly trying to pimp out FastForward Radio to some big media outlet — […]

Think of it as the Undo Button

Via GeekPress, quantum weirdness just keeps on getting weirder: In the latest issue of Nature News, Postdoctoral Fellow Nadav Katz explains how his team [took] a “weak” measurement of a quantum particle, which triggered a partial collapse. Katz then “undid the damage we’d done,” altering certain properties of the particle and performing the same weak […]

Prove the Universe is Weird

Hey, quantum weirdness is great fun to read about, but how many of us have ever gotten to experience it first hand at home? Well, now thanks to Scientific American, we can: Do-It-Yourself Quantum Eraser Using readily available equipment, you can carry out a home experiment that illustrates one of the weirdest effects in quantum […]
