Impossible Time Crystal Breakthrough - Explained

Imagine a crystal that repeated in time instead of space. If that sounds absurd, then you're in the company of many scientists.
Recently, researchers have built one, smashed previous records and shown how this science fiction sounding concept can be brought into reality.

There's an online game called Runescape. You can click to follow another player, and you'll try to stay behind them automatically. They can click to follow you and the two of you end up 'dancing' in a kind of push-pull circle. This experiment reminded me of that.

That quote from the paper at 21:10 made me think of them actually not going "We've done a thing, but can't explain how it does it" and instead a "We've made a thing. And we don't understand why it's doing what it's doing, but it keeps doing it."

As any research scientist knows, the true sound of discovery isn't "EUREKA!" But instead "Huh, that's weird..."

I agree with what you said near the end:
The engineering to construct and conduct the experiment is wonderful to behold.
However, the significance of what the results really mean is lost on me.
Keep it up Ben. Love these videos. 👍
A sign of a sequel video to explain more would definitely grab my attention. 🙂

[alexlefevre]

You had me at full frontal, and I stayed for the physics. This is incredibly well presented.

[martifingers]

I was quite out of my depth but this explanation was a perfect balance of simplifying ... but not too much.

[InternetResearch]

Your explanation was really well done, I was able to understand what you were communicating. Much appreciated, seriously!

[robbierobinson]

An excellent video. The graphics were amazing and helped me understand much more than I expected to on seeing the title. Your videos are a highlight of any evening of watching information on advances in science.

[RedWordsFirst]

That zoom in on the crystal in a watch was a piece of information that made my brain happy to learn. Something I’ve thought about my whole life but never enough to investigate it.

[PaulDriverPlus]

Why do time crystals always make my head ache and my nose bleed?

Just the idea of crystalized time alone gives me a headache.

I'm going to the hospital now, I think Dr Ben broke something in my head.

7:20 - I fell asleep listening to this video. I woke up at this part and it didn't register for a few seconds that i still had an earbud in. I was incredibly confused and alarmed.

[nannesoar]

2:15 He carries 5 pens in his pen pocket. Now THAT'S impressive.

[lioncaptive]

I find your presentation is extremely interesting and I love it more than just fascinating, witty and occasionally crystals can just bring us together.

[scrapeape]

dear youtube algorithm, this is my favorite kind of content. interesting premise, well-explained deep dive into methodology, and enticing outcomes. (note: this is a video about a recent science experiment)

[Goldbay]

Okay well you just blew my mind. I am a Gold Miner but I specialize in a very specific type of gold and that is crystallized gold. I just learned more from this video than ever on how to now explain to people the difference between crystallized gold and crystalline gold. I just subscribed to your channel I'm looking forward to seeing more of your content

[xalaxie]

best description I've seen of this time crystal experiment so far. really really well done and so fascinating. makes me want to try to design experiments!

[gerryjamesedwards]

Hang on, though, if your pump laser is circularly polarised doesn't that mean that it's not constant? It's energy may be constant, and its wavelength, but the polarisation could be said to be oscillating, no?

[craigvonberg]

Given a choice, I prefer a complicated-but-thorough explanation to an overly-simplified one. Thank you

[JessWLStuart]

I worked at a place that measured Birefringence using polarized light. I was able to keep up with all of your description! I guess I'm chuffed over that!

[andrewpincombe]

I understood next to none of that but enjoyed it immensely.I look forward to being equally baffled by your future work.Bravo Dr.Ben

[kevinboles]

There are SOOOO many "energies", pretty much all on a quantum-effect scale, that it just SEEMS like there could be something going on that we do not fully understand yet. It could be an unknown energy transfer or effect, minute energy loss in one of the umteen inputs, an uncharacterized quantum effect, etc.

It is still INCREDIBLYinteresting. And as you stated, the technical aspects of the experiment are astounding.
