Thanks to observations of galaxy redshifts, we can tell that the universe is EXPANDING! Knowing that the universe is expanding and how quickly its expanding also allows us to run the clock backwards 14 billion years to the way the...

Discusses the Big Bang Theory about the formation and expansion of the universe, what problems this theory presents, and how to conceptualize seemingly impossible ideas, e.g., that the universe has no edge. [11:02]

Knowing that the universe is expanding, and how quickly it's expanding allows scientists to run the clock back 14 billion years to the way the universe began- with a bang. [13:23]

Learn how dark energy accelerates the expansion of space. Find out about the theory that the universe will expand indefinitely and faster all the time. [11:22]

To understand that our universe is constantly expanding, learn about those first few minutes of the universe's life. [12:35]

Crash Course walks students through the start of everything: The Big Bang. We'll look at how the universe unfolded at its very beginning, and how everything in the universe that we know today came into being. [14:26]

Has the universe a beginning or was it here since forever? Well, evidence suggests that there was indeed a starting point to this universe we are part of right now. But how can this be? How can something come from nothing? And what about...
