If you erase the past, the future become non-existent.
Look under electric universe models and aether models.
Along that path, you will find that our current model has so many holes, that it may as well be thrown out just because it is so bad.
Such as, the speed of light is supposed to be the speed limit, but there have been many tests that show speeds in excess of c.
The speed of light, as measured, was changing... until scientists got together and set it.
The theory of relativity breaks down when you accept the presence of entangled particles.
Etc.
And sorry, I really can't do anything but hint at there is more out there.
