I've been a bit late in posting this due to racing to finish my last post/video on the Kalam before going through a major two week project at work.
What I want to share is another great science education video by Phil and Monica who post on YouTube under the handle SkyDivePhil.
In this video they go through some more of the theories being worked on in modern physics to help us describe what could possibly be "before the big bang", with a focus on String Theory.
They both have a good knowledge on the subject and do a great job of helping to communicate it to a lay audience. What's more is that they have access to the scientists working in the field and got them to agree to an interview. This is truly a gem of a series and the video is extremely dense with information that attempts to give a look at what would be entailed by the theories if we were ever able to prove them. Spoiler Alert: There's no god required.
I highly recommend giving it a look.
