Until the "big bang" was discovered there was an apparent contradiction in Genesis.. Science by definition is defined by observing the "natural" universe. Since the big bang resulted outside of this , the big bang by definition had unnatural causes or Supernatural causes .. Ie: God.. "a singularity" moment.. A God moment. Science celebrated this discovery until they realized it had a "God moment implied" Science scrambled to create new theory's .. Steady State theory ( which was debunked). Then the multiverse theory .. Which by the way is not theorized by empirical evidence or experience which science is suppose to use .. But by a philosophy of the "no God" of science by definition.. Even Peter singer ( leading atheist) concedes this point and says.. "Well we don't know but in 50 to 100 years probably we will" hence.. Science ,like evolution, has become a God of the gaps for the Atheist. What I find most humorous about this theory "besides" the absence of ANY empirical evidence or observation is our inability to ever see beyond the ( CMBE ) - Cosmic Microwave Background Emissions.. What does this show?? it shows that science has a a philosophy behind it. a "no God" philosophy, even if it it means positing a theory that has no empirical evidence or observation to support its claims.
There can be another universe put into our universe, as it is possible. This will expand everything. Our universe is already expanding and there is life from other communities in another universe besides ours really. It's quite confusing to me, but it all has interesting facts :)
