There is currently no scientific evidence or widely accepted proof that time travel has been invented. The concept of time travel remains theoretical and is still a subject of scientific research and speculation.
it hasnt even been confirmed so not for a long time

This difference isn't really measurable but we know that it's there.
it hasnt
i think because time travel may be possible scienctist can
