Is it theoretically or just practically impossible to determine what happened before Planck's Time (10 to the minus 43 seconds)?

Actually, it is practically impossible to determine what happened at much later times than Planck's time, since we only receive radiation and similar evidence of events from much later times. So, since theories must be subject to evidence, the theories are probably not going to be testable (unless we build really huge particle accelerators to test the appropriate energy ranges), and therefore we will never know if the theories are right, so it is really also theoretically impossible (at least according to the usual scientific method) to know what happened before a time much later than Planck's time.
