What’s Wrong With the Big Bang Theory? | Space Time | PBS Digital Studios

Now that we have a primer on the aspects of the Big Bang Theory that we know definitely happened, let’s look further into what we don’t yet know, and how the theory could progress in the future. Since there is a discrepancy between general relativity and quantum mechanics, we continue to search for a grand unifying theory... one which may finally lead to a description of the actual moment of the Big Bang! On this week's Space Time, Matt describes what specifically needs fixing within the current theory, and the reasons why.
