The Big Bang is the term that scientists use to describe the beginning of the universe. In this video, Fermilab’s Dr. Don Lincoln clears up many common misconceptions about this fascinating topic.

What I really appreciate (besides the content) is, that no music is played during your talk to make it seem more impactful. You just don't need music and I can listen 100% to your words. Thank you.

Dude. SO AWESOME seeing you on PBS SpaceTime yesterday. SpaceTime and Fermilab (only because of Dr. Don) have long been my two favorite channels on YouTube.

I sometimes wish I could skip ahead 500 or 1000 years, to find out the answers to many of these questions!

@1:41 "Scientists admit when they don't know something" I love this.

1AM in Lithuania... Me: A great time for some astrophysics!

“Scientists admit when they don’t know something...” Best burn today. 🙌🏻🙌🏻🙌🏻

I like the fact that he’s wearing a shirt that reference the show called the big bang theory and then has his own show about the Big Bang

[vknidhi]

Fantastic explanation. Your accent is clear and straight forward, your pauses and speed of delivery is precise, there are no musical disturbances, your body language instills confidence in the audience and the l lecture is so splendid. I can listen to you endlessly. Fabulous. I'm bent on learning a lot from you, sir.

I can’t possibly express how much I appreciate this channel. Thank you (times) infinity.

Me: "Yeah, I think I have a pretty good grasp on the Big Bang."

Dr. Lincoln: "Hold my beer..."

I am 82; I am not a scientist. But I have developed a strong interest in it.

Dr. Lincoln presents his key ideas in a clear, understandable manner. When I think of all the university professors that I had in under graduate and graduate school that mumbled, Dr. Lincoln is refreshing.

[aldiboronti]

That's the clearest explanation of the theory that I've seen. So much misinformation out there.

[MichaelDonlinAwesome]

HAHA, yes!. "(clears throat) giant sphere..."

[jamesepperson]

I have waited my whole life to find this video. I now feel happy with an understanding of the universe that I didn’t have before. Thank you so much for simplifying this complex topic for me

"Well nobody was there at the time, so we can't possibly know anything"

If someone told me that I would ask them, if your house got robbed and nobody was there at the time, but there *was* any kind of DNA to trace back to the culprit, would you dismiss it because simply nobody was there at the time? 0:37

Great stuff as always, one thing I would add is the misconception of the "before" the big bang people often have as well. Time-space is not a separate phenomenon so when space is condensed to a tiny speck, time also behaves differently and so time very likely began with the expansion itself. There most likely was no "before" the big bang as time simply didn't exist.

[oaktadopbok]

This is brilliant. Dr. Don is an excellent story-teller.

[mystikinfinitie]

Clearing throat when obviously a giant sphere thank you I love you for that.

[JP-vsys]

This is so well done. Covering misconceptions in a way that is approachable.

They need to emphasize more earth science in high school.
