I was wondering if it were in actuality possible to assume the universe was created from a big bang, as it seems we used current understanding of the laws of physics as they apply to us now, and extrapolated back. Could it be possible that the boundary conditions we form our laws of physics upon could have changed somewhere along the way? So that the current universe looks a lot different to what it was, or what it was evolving to be?
EDIT: To highlight, I remember an example in a book I once read. Imagine one happens upon a room temperature glass of water. According to the laws of thermodynamics, it is impossible to determine an earlier state of the glass of water for certain. For instance was the glass initially hot, then cooled? Or was it always room temperature?
