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?

  • And now that they know they can affect those conditions, could they in theory engineer a nicer universe for us? And if they could, what would happen if some future scientists believe they can do a better job? And then some others still... What would happen if a whole dynasty of scientists try to tamper with the same moment in the earl history of the universe?? You just solved quantum uncertainty! - By the way your question reads like something for Physics SE, unless you make it more Philosophic'ky it will probably be closed. Maybe an Ethics angle, or metaphysical... – christo183 Nov 27 '18 at 5:29
  • Apparently, you are assuming that the past is changed due to Wheeler's experiment. That's wrong. Quantum mechanics hold with or without experiments; apparently such fact is not accessible to our macroscopic perception. – RodolfoAP Nov 28 '18 at 20:32
