Stephen Hawking: Nothing existed before the Big Bang

Stephen Hawking Says He Knows What Happened Before The Big Bang.

Any time you hear a scientists talk about the origins of the universe it always begins the same way. “It all started with the big bang,” they say, and from there humanity has built a rough timeline of the events that led us to today. But what about before the big bang? You rarely hear physicists attempt to explain it, but renowned thinker Stephen Hawking believes he has the answer. As you might imagine, it’s not the easiest thing to grasp.

Talking with Neil deGrasse Tyson on his popular Star Talk radio program, Hawking dives into the nitty gritty of what existed before the big bang. As Hawking puts it, the answer is “nothing.” Of course, it’s a bit deeper than that, so put on your thinking caps because we’re about to get weird.

“According to Einstein’s General Theory of Relativity, space and time together form a space-time continuum which is not flat, but curved by the matter and energy in it,” Hawking explains. “In the Euclidean approach, the history of the universe in imaginary time is a four-dimensional curved surface like the surface of the Earth, but with two more dimensions.”

Um, okay, so now we’re thinking in six dimensions. To better explain exactly what he means in a way that us mere mortals can actually understand, Hawking likens the space-time continuum to a sphere. The surface of a sphere has no beginning and end, it just exists.

“One can regard imaginary and real time as beginning at the South Pole, which is a smooth point of space-time where the normal laws of physics hold,” Hawking says. “There is nothing south of the South Pole, so there was nothing around before the big bang.”

The idea here, if I’m understanding correctly, is that the universe didn’t exist, and then it did, and now it does. Attempting to actually grasp this idea is no easy feat, and it’s possible (even likely) that humans simply can’t fully understand the concepts needed to explain how the universe originated. But hey, we’re here, and so is the universe, so that’s a plus. That’s pretty neat!

    He has explained nothing, he is speculating what happened too long ago to know. So I call BS. There’s more chance that God created the universe than any human ever knowing. I’m not religious but the more rubbish scientist make up the more I think there is a God.

    It’s impossible that a reaction didn’t have a cause for that reaction to take place. So to say there was nothing before the big bang is a scientist that has given up trying to find the truth.

    Do you wanna know something ? I believe scientists can understand a lot , they know they things eminate from a central point thanks to the observable evidence in the sky , but as for what actually caused it, can’t see it ever being answered . But I’m a firm believer that something can come from nothing or better put just exist and expect st for the sake of existing. And it’s our stupid primate brains that always think things need to be created . We are debris in space , could be wiped out at any time .

    There is no such thing as nothing. Nothing is a myth, a falsehood and creation of mankind. Anyone including the most brilliant mind of our time who’s says nothing existed is providing the most simplistic explanation possible. Think of a child who panics when their balloon burst and says I didn’t do anything, I done nothing. It is actually the concept of nothing which is easier to comprehend. So I get that there can be no light, no time no space but then everything was suddenly created out of nothing, sounds very familiar that explanation, “and God said let there be light and there was light”. A bloody big explosion professor Hawking. I think John as a very valid point you can’t make it up as you go along. If we learnt anything from the Monty Python film the life of Brian, making things up as you go along is how messiahs are born.
