A competing theory to 'dark energy' suggests universe has different time zones

Quirks and Quarks 19:35 Is dark energy dying? A new theory suggests that the universe has different time zones There's a cosmic controversy brewing in the universe. It centres around the mysterious force known as "dark energy." This concept emerged from observations of distant supernovae that, in the late 1990s, seemed to indicate the universe had been expanding at a faster and faster pace ever since the big bang. Astronomers made these observations from a certain type of supernovae that explode in such a way that allows astronomers to calculate their distance from us. The picture emerging from that data didn't fit with previous explanations of the universe that theorized its expansion, driven by the big bang, would eventually slow down as gravity took over. This led scientists to come up with the idea that a force they called "dark energy" pushed against gravity to make the universe expand faster and faster, in keeping with the supernovae data. But since then, astronomers have mea ... Read full article.
