Any theory that begins with
We have no possible way to measure this but....
Is bullshyt.
Until they find a way to measure it.
So alternate Universes, time travel, dark energy, simulated Universe, worm holes, and alot of 'Science' is more like Sci fi.
No. No. The rocks are actual rocks until PROVEN otherwise.
If the Universe is a simutation
Then there has to be a computer sitting
Somewhere
In a real world
That's generating the simulation
Or is it simulations 'all the way down' (a play on people that think the Earth is being carried by a big ass turtle saying that the turtle is on the back of another turtle and it's turtles all the way down).
That simple factoid destroys the idea that this isn't the real world. Cause there has to be a real world at some level to be able to have a Matrix for us.
So if there is a real world, why assume that this isn't it. Since we can see this one and it seems extremely real.
