Alan Guth believes he made that match more than 20 years ago. In 1979, the young physicist invented inflation theory, which described why the big bang happened and then what happened in the next ...

Alan Guth is a man with a tendency to laugh at himself. That's clear from the first question I ask him: How old are you? "I'm 67 years old," he says.

Guth's story begins in Highland Park, New Jersey, where he grew up and attended public school. "Neither of my parents went to college," he says. His father was a grocer and, after a fire destroyed ...

Physicist Alan Guth, the father of cosmic inflation theory, describes emerging ideas about where our universe comes from, what else is out there, and what caused it to exist in the first place.

And at the end of the exhibit—with a note pointing out that this is still work in progress—is Alan Guth's notebook, with his original calculations and the “SPECTACULAR REALIZATION.” Like the ...

Before Alan Guth came along, cosmologists seldom dared to guess. The Big Bang theory, based on speculations dating back to 1922 and confirmed by astronomers in the 1960s, posited that the universe ...

In the 1970s, physicist Alan Guth concocted a radical picture of the extremely early universe. Originally intending to solve some troublesome properties exhibited by the high-energy physics in the ...

In 1981, physicist Alan Guth proposed the theory of cosmic inflation. It suggests that during the earliest moments of the universe, it expanded 10 26 times within 10-36 seconds.

Before Alan Guth came along, cosmologists seldom dared to guess. The Big Bang theory, based on speculations dating back to 1922 and confirmed by astronomers in the 1960s, posited that the universe ...

For decades, scientists assumed that the expansion of the universe was powered by a new entity, known as the inflaton, but new research suggests that it may have been possible without it.
