Very interesting hypothesis.
It always struck me that some people try and limit God by saying he couldn't do this or that due to some law of physics.
My answer to that is that if God created the laws of physics, He could just as easily change them to suit his purpose whenever He wants.
One other thing (not to get off point) is that in the literal six day creation, you'll notice that God first created the plants and life BEFORE he created the sun and moon (In Genesis it is called the greater and lesser light, and were made on the ?? third or fourth day I think).
According to our known laws of physics, the sunlight would be required to sustain plant life, would it not?
Does it actually say that He created plants and put them on earth, or does it say just that He created plants. Isn't it possible that plants existed on other planets before the earth existed?
You mat want to do some research on Super Nova 1987A (SN1987A). You seem truly curious and I think you would find this fascinating. Here are a couple of links (There are many more):
