Quantum and Relativity complexities - does anyone gets it?

[Skhandelwal]

1. How can 1 electron pass through 2 holes?
2. How is speed of light unrelatively absolute in vacuum?
3. How come objects contract and mass gets bigger w/ increase in velocity?
4. the train-lightning experiment: how velocity affects time for observer?

Please list more questions that I missed.

Now w/ the real problem....everyone through mathematical proofs know that this happens...but does anyone really know the reason why? I mean did he even discovered it? Did Einstein just steal someone else's discarded research on unaccelerating light or did he actually added his understanding on why exactly light behaves the way it does.

To point 1 Feymann said is was the problem of QM
