    Virtual particles are a way of talking about fields and their interactions as though particles are doing all the work. This is why there is some controversy around using the term 'virtual particles'. Some people think the term is useful, especially since in calculating with Feynman diagrams you draw all the particle interactions that are possible (and then do the calculations to get the right answer). While others feel this terminology is misleading because virtual particles don't behave like real particles and can't be observed.

I love it how Physics has so many "We are 99% sure that the value is x, and 98% sure the value is y, the only problem is they are very different values, both calculated with high accuracy"

To everyone saying this sounds weird, remember this 8-minute-long video is a summary of several thousand-page-long books.

Man, its really hard to think of the universe as just overlays of fields. It feels and looks so physical and 3 dimensional.

When I first saw this video I was still in highschool and I thought this is a fascinating effect I never really learn more about. Now I'm studying physics and in three days I'll have my first exam on quantum mechanics.

I aint no scientist but I have some time off work next week and I've decided to solve all these problems, so fingers crossed.

Great video! One minor critique I would have: I really feel like you should have brought up the Casimir effect in regards to virtual particles. I realize its a bit of a lengthy explanation to break down the experimental apparatus and whatnot, but I've always felt that it does the best job of helping get a real-world "feel" of virtual particles existing.

As much as I love physics, sometimes I think we are too deep to see the meaning of things. Like a picture make out of pixels if you look at one pixel to try to understand the meaning of the picture it will be impossible. Sometimes is better to step back to see the whole picture. I love Veritasium keep the great work.

It's amazing that year by year, you post things about more deeper fundamental concepts. This just keeps me excited. Thank you very much. Keep up the great work!

omg, that vibration in a field graphic is by far one of the clearest and most mind blowing things I've seen in a long time...

I need more Sean Carroll. He's one of my favorite science orators by FAR.

This was super interesting! When I was taking General chemistry, I wondered if there was anything else in an atom besides subatomic particles, since I feel like completely empty space doesn't exist in the natural world. I would love to learn more about virtual particles because they seem like their own little world.

I'm surprised to see no mention of the casimir effect in this video - isn't that rather good evidence for the existence rod virtual particles? Also, please correct me if I'm wrong, but isn't Hawking radiation and the evaporation of black holes caused by virtual particles manifesting on the edge of their event horizons?

I think it's high time we dedicate an SI unit for energy instead of using ergs. That joule guy was pretty awesome, we could name it after him
