Perhaps you saw the news this week about new evidence that we do, indeed, live in a multiverse. A scientist claims he’s found signs in the cosmic microwave background radiation — the afterglow, so to speak, from the Big Bang — that our universe collided with another universe early in our cosmic history.
Until the early 1970s, if problems with penile blood flow or nerve function meant a guy couldn’t get it up, his choices for treatment were pretty limited, and certainly did not mimic nature.
Last week, physicists announced that they'd discovered evidence of gravitational waves in the early universe, which makes it more likely that our universe began with a bang and inflated from there. But that also means a whole host of other things, including possible multiverses.
Watching Andrei Linde and Renata Kallosh hear that BICEP-2 found gravitational waves is heartwarming. But with a bit of translating of everything left unsaid, it becomes even more gut-wrenchingly awesome. Allow me to translate for you to see this through a physicist's eyes.
Today, Harvard's servers were brought to their knees dealing with international demand to watch a press conference about ... gravitational waves. It's no surprise: as physicist Marc Kamionkowski reflected, "It's not everyday you wake up and learn something completely new about the early universe."
We still haven't found the Higgs boson, the hypothetical particle that explains why other particles possess mass. But that might not be the only cosmic mystery the Higgs can solve. It could also explain how the universe got its shape.
When it comes to the Big Bang, you shouldn't believe everything you hear. In this week's "Ask a Physicist," we ask whether hyperinflation of the entire universe is sensible or just plain nuts.
The laws of physics only work in a finite universe, but we likely live in an infinite multiverse. Resolving this discrepancy could mean a 50-50 chance time will end in 3.7 billion years. Yeah, this one's going to get weird.
A hypothetical "inflaton" particle fueled the universe's initial expansion out of a single atom - all in the fraction of a nanosecond. And we might soon find the particle responsible. Get the scoop via New Scientist.
