Time Crystal

An experimental accident made my left hand age and my right hand young. Time in the laboratory completely collapsed, at varying speeds. And we received an ultimatum from higher civilization: "Error sequence. Initiating zeroing protocol." If you want to survive, you must pass their test. But the first question on the test paper is: without direct contact, use the aftermath of time to send a particle to the future one second later. We think we are searching for the truth, Little did he know that the entire earth's civilization had just received a probationary student notice for "Universe Elementary School". The first rule of the school rules is: It is forbidden to seek death, and those who violate it will be annihilated.
