It has been mostly substantiated by virtue of experiments such as wheelers delayed choice quantum eraser experiment that we are able to retroactively impact past events of particles. However could this apply to the universe. When physicists are carrying out experiments today, which are creating the conditions of the big bang, prior to the experiment it is uncertain what they will find, because it is uncertain how things behaved back then. That means by experiment that physicists are retroactively determining the laws of physics and even what happens today. This could have devastating consequences potentially since effecting the conditions of the big bang could dramatically effect the conditions today.
Please tell me what you think of my thought experiment?
