Inspired by Queer’s post <<< if I could have a dime every time I said that, I would have a dime.
This thread is about the concepts of Science that are confusing for you.
One of the biggest mind bogglers for me is the multi-dimensional space. Super String Theory, which is considered to be the best candidate of the Theory of Everything (the theory that attempts to combines General relativity and Quantum physics), states that our universe has 11 dimensions. Four of them are visible to us, and rest curled up to such small radii that they are no longer visible to us. That curling of course happened right after big bang.
Ok now share the concepts of Science that you find mind boggling.
