Reality, Einstein said it made no sense and it doesn't

In modern physics strange theories are routine,

 e.g. in many-worlds theory each quantum event divides all reality, so everything that can happen does happen, in an inconceivable multiverse of parallel worlds (Everett, 1957). 

In the inflationary model, the physical universe is just one of many bubble universes (Guth, 1998) others suggest we are one of two universes that collide and retreat in an eternal cycle (J. Khoury, 2001).

 The days when physics just described the physical world we see are long gone. Yet the findings of physics are equally strange: the sun bends light by curving the space around it; the earth’s gravity slows down time; 

and atomic clocks tick faster on tall buildings than they do on the ground. 

Movement also slows down time, so an atomic clock on an aircraft ticks slower than a synchronized one on the ground (Hafele & Keating, 1972), 

and moving objects become heavier with speed as well.

 In our world, space, time and mass vary but the speed of light is strangely constant. If relativity is strange then quantum theory is even stranger: in Young's experiment one electron goes through two slits at once to interfere with itself; entangled photons ignore speed of light limits; the vacuum of space exerts pressure; and gamma radiation is entirely random, i.e. physically uncaused.

 Einstein, who was as open to new ideas as anyone, thought quantum theory made no sense, and it doesn’t.

{quantum mechanics} does not give a clear answer to the question of what, if anything, objective reality is.” (Nikoli´, 2008) p43 The way forward proposed here is to examine the   “hard” question: “What is reality?”

But Physics continues apace and those white coats in the vanguard are leaning towards the hypothesis that we live in a virtual reality,

For instance:

Quantum theory rules the microcosmic world from which our reality emerges, so when we look at the table in our macro world we are satisfied it is a table, viewed in a micro way it is constituted by the virtual and relativity rules the cosmic world around it.
