I always love talking about this guy
he's a biologist who thinks he knows philosophy
he's one of the ever growing people who believe that in a universe without matter (even though the building block or elements were probably always stored in this world) anything is possible at any specific time
but no it gets serious, progress didn't even exist before the big bang according to their logic, like if the galaxy stopped breathing for a second, that second would go unnoticed.

I'd like to know why certain rules of nature are implemented when there's suddenly something in space, and why the same occurance doesn't commence after the arrival of something
because let's face it, space is unending nothing, there is no difference between space before the big bang and after it
yet this is what they believe
some illogical comparisons and assumption and a whole lot of speculation

instead of a world without a controller, one particle or entity that set motion to the cogwheels of action reaction, they believe in magic, that anything is theoretically possible inside nothingness
so starting tommorrow you might see an enormous cancer arrive in the galaxy that will expand and devour us all in a variable instance of time

it's even more logical to think that there never was a big bang than to believe in that notion, that everything has been spinning all along, without a start, middle or end.
but if it actually started for US then you can only conclude that some kind of motion traveling interdimensional started it up.
what attributes this force has or had is only to be speculated about, and science will never be able to get a definate answer.
