The first experimental realization of a dissipative time crystal

A time crystal is a unique and exotic phase of matter first predicted by the American physicist Frank Wilczek in 2012. Time crystals are temporal analogs of more conventional space crystals, as both are based on structures characterized by repeating patterns.

Why physics suggests other dimensions exist - BBC Reel

Theoretical physicists point to the idea that there are other dimensions out there, beyond what we can see. And there could be loads of them, as Melissa Hogenboom explains. A film by Melissa Hogenboom and Pierangelo Pirak

Diffraction

You can easily demonstrate diffraction using a candle or a small bright flashlight bulb and a slit made with two pencils. This bending is called diffraction.

Now read that magazine, but slowly and in a breathy voice. Psytrance samples gold.

Do numbers exist independently of humans?

 

[NabLa]

Do events happen without observers?

 

[Torsion Jim]

Depends on the event

 

[NabLa]

There's your answer then.

 

[Torsion Jim]

No it isn't. That's barely an answer

A number would only exist if its applied to a solid object. Otherwise they are abstractions. If no one is there to apply the number in question then it doesn't exist independently of the mind

> A number would only exist if its applied to a solid object.

Why though? An object exists, but the act of numbering them is a conscious effort. If there's no mind to think of it then there's no number. The object or objects just are.

Do quantum events actually happen without an observer? If they don't, how could time even exist? What is an observer?

Do mathematics exist without the mind? Or are mathematics an abstraction over nature's behaviour, by minds?

Your question is basically straddling the line between science and philosophy.
