Universe expansion: dark energy's out, anti-gravity's in, matter and antimatter still can't get along
Dark energy, we barely knew you, but before we ever found out if you were, in fact, the invisible hand pushing the cosmos apart, an Italian scientist ginned up a new theory that has anti-gravity doing the Yoko Ono to the universe's merry band of galaxies. Massimo Villata's theory assumes that both matter and antimatter have positive mass and energy density, which gets particles attracting particles and antiparticles attracting antiparticles through the force of gravity. To give dark matter the heave-ho from the galactic expansion equation, Villata supposes that the theory of general relativity applies in reverse to antimatter particles to create anti-gravity. And just as gravity pulls particles together, anti-gravity shoves them apart -- giving the universe its burgeoning waistline, no clown, king, or colonel required.
AlterG's M300 treadmill: same 'anti-gravity' vibe, now 'only' $24,500
We've always heard that holiday calories "don't count," but disregarding urban legend for a minute, we'd say AlterG's timing here is nothing short of impeccable. Nearly 1.5 years after the outfit's P200 series was a-okay'd by the FCC, an all new walking machine has entered the fray. The M300 treadmill brings along the same "anti-gravity" feel (useful for rehabilitation and athletic training), but in a machine that's a third of the price and way, way sleeker. The idea here is to reduce the strain on joints and muscles as one exercises, and while that's certainly commendable, we're still thinking it'll take one or two more iterations to get one priced for the everyman. You know, unless you consider $24,500+ (or $499+ per month for the rest of your Earthly life) "affordable." [Via MedGadget]
