Has the Poincaré Recurrence Theorem been observed for in a real system? Can we build a sufficiently small system where this can be achieved?

If 1 eV equals roughly 12000 K, why are there semiconductors with a band-gap of, say, 2 eV that can achieve conductivity through thermal excitation?

Why do we sometimes get lightheaded and start hearing a sinewave sound out of nowhere? I just got lightheaded and started hearing a C4 note for about ten seconds

As the universe expands and more space is created between subatomic particles, do they adjust their interactions accordingly, or eventually atomic nuclei will be torn apart?

How do different substances interact with your tongue to give different taste sensations? Why, for example, water is virtually tasteless while heavy water (D2O, where the hydrogens have one neutron more) tastes slightly sweet?

If a 4D object temporarily intersected our 3-dimensional world, theoretically we would see only the 3D intersection, and it would change its shape as it passes by. What would happen if you grab this 3D intersection as it passes through our world, and not let go of it as it vanishes away?

According to the mass-energy equivalence, whenever energy is added to a system, the system gains mass. But hum.. "where" is this new mass located? And what kind of mass is it, it's like some subatomic particles that just came to existence?
