An armada of alien spaceships of various colors and designs instantaneously appeared to hover over Earth; one of the ships broadcasted a message: "We've come for the criminal. Hand them over now!"

"Who are you?" asked One Earth's space command.

"We're enforcers representing billions of intergalactic species. They must be brought to justice!"

During the trial, 'The Defendant,' a trillionaire time traveler inventor, sat quietly next to their team of defense attorneys as the intergalactic prosecution's 'time travel expert' demonstrated evidence and gave testimony:

"Due to the nature of time travel and why it's been rightfully banned, the traveler remains protected and frozen in a spacetime bubble but propels relatively through the fabric of infinite spacetime as the universe itself moves, creating an unstoppable weapon of mass destruction, displacing whatever is around them, reaching incalculable speeds and trajectories the further forward or back. Thus, this Earth time traveler has recklessly destroyed countless worlds and civilizations because of their careless misunderstanding of the concept."

The time traveler sighed, lowered their head, and muttered, "If I could only go back and change things …"

The alien expert replied, "Exactly my point! Earthlings simply don't get it!"
