ScienceCasts: Quantum Foam

As 2015 comes to a close, tell us which ScienceCast you've learned the most from! What do you want to see in 2016?

Researchers have used NASA space telescopes to prove that space-time is much less "foamy" than some models predict.  Understanding their result requires a trip into the world of quantum physics.

I made it through all four minutes and my brain only partially imploded! [Rocky theme]

This is the best explanation for the educated non scientist of q. foam. I am surprised at its simplicity in the telling when the math is sooo involved. So this is my nomination for the one I learned the most from.

This is Bayes at quantum-scale; if the substrate is actual, then all events in spacetime are co-eval, co-extant &
co-terminous, & equally accessible via the 6, 10 or 11 putative dimensions.

1:19 this is what I see when I press my eyelids hard against my eyes with my hands.

Hey ... Michelle Thaller! You are one of my favorite astronomers! :)

Happy new year :D, best place to post!

Wikipedia has a section on quantum foam here:


It helps to have a printed section on this and other subjects for readers to view and get a better understanding of the subject.

It blows my mind that people can dislike science...

[kevinolesik]

well that was interesting ... it made me go open a can of beer for further research ...

Effusive: What, is inside, the foam: less dense space, or unsaturated, space? In the model I occasionally refer-to, the model, noodles broadside noodles—and create momentary diversions in every BVL-noodle path...

An integral part of that ever famous Quantum cloud

could upload from now on only in 1440p please ?

Who is narrator?
Is it Barbara Oakley from OU?

[tthompson]

Now you got me contemplating a planck size quantum beer.

Quantum foam, brought to you by Duff beer.

So basically, the mind bending theories of bathing

[TonyP]

That sounds like Lisa Randall narrating.

[breadbassed]

Quantum foam, or monadic singularity??

[Dyslexic-Artist-Theory-on-Time]

Would it not be better to try and explain the Universe relative to what we can observer rather than coming up with ideas like ‘quantum foam’ LOL

[NickNathanson]

I hope string theory is the right thing to explain "everything", I want 10 dimensions =)
