Does science in general scare you or makes you feel small? Specially physics and mathematics? Do you ever, however briefly, think about how little the average individual knows about the universe we live in and how irrelevant we deem it to continue our everyday lives?

Did they create a four-dimensional object?

"Normal crystals have an atomic structure that repeats in space - just like the carbon lattice of a diamond. But, just like a ruby or a diamond, they're motionless because they're in equilibrium in their ground state. But time crystals have a structure that repeats in time, not just in space. And it keep oscillating in its ground state. Imagine it like jelly - when you tap it, it repeatedly jiggles. The same thing happens in time crystals, but the big difference here is that the motion occurs without any energy.

Saw this video a couple of hours ago. It shows the amount of suns (like the one in our solar system) that can fit inside of different sizes of black holes, when crushed into a particular size. I kinda like this measurement videos that show the scope of our insignificance.

Science used to terrify me when I was young. When I was about 6 or 7 years old, I got a copy of A Brief History of Time and I learned about space stuff. The timescale of cosmological events being so long compared to human life really freaked me out, as did the concept of infinity for similar reasons. It was like true Lovecraftian horror to me, and it messed me up for many years.

I don't think most people would really benefit, practically or intellectually, from knowing a ton about physics. It might be interesting to some people, but most people will neither benefit nor care to know whether gravity is the result of some hypothetical graviton particle or something entirely different. A naive and uninformed view of the world enables people to live unencumbered by unnecessary worrying and spares those with little interest from a subject they would find dull. Leaving particular topics in science in math to only those whose passions drive them to study it is enough, in my opinion.

I think time crystals were a bit overhyped by science journalists and made to sound more complicated than they really are. As I understand it, time crystals have a regular structure like normal crystals, but they also wiggle around in a manner that repeats over time, like a spring oscillating back and forth. I am sure a lot of the finer details are pretty complicated, but it is really regrettable that science topics are communicated in a manner which is deliberately confusing or excessively aggrandizing as understood by regular people.

What is more wondrous to me is the fact that mathematics "works" at all. We started with some simple numeral systems that had a direct, clear correspondence with entities in the physical world but very soon built up to complex abstractions. And now working at these highest levels – that are far divorced from the physical world yet have been implicitly shaped by the axioms we chose to match notions of the physical world – we play the game of logically deriving new ideas from prior ones. And not only do these ideas we stumble upon – more of an art than a science – seem to all be interconnected, but they crucially also end up being able to be used to explain things back in the physical world (although the frontier of pure math is usually decades ahead of its applications in physics).

So even though we're clearly just inventing notions, the fact that we keep stumbling upon these interconnected things strongly seems to hint that we're "discovering" some sort of underlying hidden structure – perhaps either of our own mental processing of reasoning and logic, or if you want to be grandiose and optimistic then some sort of underlying structure of the universe.

Quanta magazine is the gold standard of understandable reporting in physics/math. Here's their explanation of time crystals

I think about this a lot. The half-baked rationalization I am most satisfied with for the moment is that mathematics is so successful at describing the world since it is an enormous repository of arguments; while it may not be the case that every mathematical argument is relevant to real-world phenomena, we are forced to turn to mathematics to find means of concretely describing and articulating what we observe about physical reality. Now that I write it out, though, this revelation seems pretty vacuous.

In any case, yes, it is very interesting that a handful of axioms consistent with how we understand the world could bear so much fruit.

"The Unreasonable Effectiveness of Mathematics in the Natural Sciences" seems relevant

No. The theories of mathematicians don't bother me at all.
