In this episode of the Space Time Journal Club Matt discusses how two independent research teams created their own Time Crystals, a form of matter that breaks time translational symmetry and could be used in quantum computers.

It is astonishing, that no matter what bizarre physics question I ask to youtube, Matt is always there to answer.

[tesseraph]

"The first practical use of time crystals may be in quantum computing."
What a time to be alive <3

[DrTryloByte]

"A quantum computer with a time crystal drive" Holy Shit. Just the sound of that...

[giancarloantonucci]

It is remarkable how Matt is capable of simplifying all these difficult concepts. This should be usual for the whole academia, where instead bad writing is the common practice. Well done, Space Time!

4:02 I wonder what would happen if someone arrange the ions in this configuration: ↑ ↑ ↓ ↓ ← → ← → B A

[ZoneNet]

This is probably the first space time episode I have watched where I simply had no fucking idea what he was talking about.

[Rubbergnome]

A colleague and friend of mine is now working on her master's thesis on time crystals! They are a niche topic, I'm very happy that you guys covered it. Great job!

[AlphaFoxDelta]

Beautifully done, the concept of this series to break down new papers, analyze and simplify them, and then discuss the results here is one the best methods to popularize science! Everyone can do it and everyone can become knowledgeable!

[UltimateBargains]

I watched the entire video. I only have one question.

What?

[Flyingdeath]

It’s 2024 now my friend. PBS always comes thru with the fire 🔥 🔥

[bostonmetalclips]

Who else is here in 2021 having Matt explain the news?

[sejalyadav]

The thing I love about these videos is that you just don't simply watch it but have to put in hard work by researching on the topic to fully grasp the concept and then watch it again a couple times.A great way to brush up your knowledge.

[sigton]

So basically time crystals are like the quartz in a wrist watch but at a quantum scale? Cool. I like the idea of quantum pocket watches!

[georgep]

one of the few unlazy channels that actually tries to visualize these complex concepts the best way they can y'all deserve an award for that. thank u

[GuyNamedSean]

The best thing about Wednesdays. I love Space Time.

[mvmlego]

This was _immensely_ better coverage of time crystals than DNews. (I won't say infinitely because singularities give quantum physicists nightmares.) They couldn't even get a Newtonian explanation of potential energy right, so I had no idea what to make of the rest of their video. Thank you for all of the hard work you guys put into your science videos. You've done more to make theoretical physics accessible than the entire rest of the Internet!

[StickyTank]

i'm fairly well educated, fairly well informed about a variety of sciences and i can barely wrap my head around this.

now imagine trying to explain this to someone from a century ago.

we are now basically wizards... xD

[TurboSol]

This guy has this same T-shirt in every color lol, I would love to see his closet all filled with the exact same shirts

[fpvwing]

"then we fight about it in the comments" LOL

[rethinkscience]

All the crystals we have on earth are a representation of the time density zone at which we live. By compress the shape of a crystal lattice, energy is released. If we could get a crystal from another time density zone it would warp the time density zone into a positive or negative state. If these crystal are arranged into a complete encompassing structure a positive or negative time void would be created. Time within this void would move forward or backward.
