This is a short post, because I can’t embed the video – so I’m just going to post the link to the Lightsource web site which has the video.
Here’s a web page from Caltech that goes over 3 of the 6 evidences for the Big Bang.
Excerpt:
Three main observational results over the past century led astronomers to become certain that the universe began with the big bang. First, they found out that the universe is expanding—meaning that the separations between galaxies are becoming larger and larger. This led them to deduce that everything used to be extremely close together before some kind of explosion. Second, the big bang perfectly explains the abundance of helium and other nuclei like deuterium (an isotope of hydrogen) in the universe. A hot, dense, and expanding environment at the beginning could produce these nuclei in the abundance we observe today. Third, astronomers could actually observe the cosmic background radiation—the afterglow of the explosion—from every direction in the universe. This last evidence so conclusively confirmed the theory of the universe’s beginning that Stephen Hawking said, “It is the discovery of the century, if not of all time.”
The article explains all three evidences in detail. It is important to show atheists how the progress of science has dashed their hopes for an eternal, uncaused universe. One discovery – that could be reversed. Two discoveries – that’s conclusive. Three – discoveries – that’s an open and shut case. (And there are three more discoveries not mentioned in the article – the second law of thermodynamics, radioactive element abundances and the stellar lifecycle itself).
And, of course, William Lane Craig uses this scientific evidence in his kalam cosmological argument, which is described in a peer-reviewed paper from this Astrophysics journal.
