There are many mysteries in science. I've been surprised a few times to read about some very interesting ones that aren't so well known. I'd be interested to see if anyone has had similar experiences and what mysteries interested them.

Some of my favorites are:

Why space is expanding

Why general relativity breaks down on the galactic scale

How Galaxies are formed

Question:The wave-particle duality of light and the double-slit experiment
Answer: DuaLITY is actually a triality leading to infinity. Focus on the outcome.

hint. TRANCE-FORMATIONS



How abiogenesis works (if it does)

I'm sure there are many others in every field of science. Anyone find any more particularly interesting?
