This is the clearest explanation of virtual particles I've seen.
-
I love how the more advanced physics gets, the more it sounds like you're just making stuff up. :)
-
9:29 It’s great that Dr. Don reminds us that there’s plenty of room to understand all this better. That scientific theories are our current best understanding, not absolute facts.
-
There are channels that provide pretty satisfactory explanations, but yours always shines in that regard, I'm so glad I stumbled upon it, thanks for the video!
-
More of the deep dives please, great to get to field theory which does explain this tricky subject and clears the mind.
-
That cover of Beach Boys “Good Vibrations” at the end is brilliant. Props to whoever made that!
-
I thought that was one of your best videos, especially the bit right at the end.
-
Im just a layman but this dude makes THE best explanations I have ever heard. Are these seriously free videos? These feel like they should be behind a paywall.
-
The real question, I think, is "are particles real?". The more I learn about QFT, the more convinced I become that particles are just an emergent phenomenon at macroscopic scales. Virtual particles aren't any less real than particles on the mass shell, but that doesn't actually make them real.
-
Finally an explanation that is understandable and not intentionally "mysterious".
-
0:42 - "I mean, just look right there. Do you see particles appearing and disappearing?" Me: "Oh, those particles? I thought we were calling them floaters. Maybe it's time I got my eyes checked."

I can't wait for the next string of videos. Sounds like they are going to be epic. Thanks!! 🎉
-
I still miss the mustache😋
-
This was a really great video, thank you. Appreciate all the work you do to make advanced topics accessible to curious laymen like myself.
-
Love this channel. Great explanation.
-
always a fun day when fermilab uploads!
-
Thank you, Don, you are always worth watching!
-
I find it such a wonderful relief to learn about Quantum Field theory in this way. I very much appreciated the assertiveness, driving home the validity of this model. I know the standard joke is that the more one learns about QM the less one understands it, but here I find it actually *quite intuitive*. I am waiting with bated breath for more videos discussing these concepts further! I'm actually enchanted. Great video.

With all of space being full of virtual particles, how do things move through space without any drag/friction?
-
Great and straight forward explanation
