A lot of quantum mechanics can seem strange and counter-intuitive.
That's because these effects normally only become important for tiny
objects, and are therefore absent from our everyday experiences. Ditto
for Relativity, which becomes significant for very high speeds.

But then, it doesn't really matter if we think a theory sounds bizarre.
It only matters that it can make predictions which can be empirically
verified.
