Q&A

How could we time travel backwards without killing everyone with germs from the future?

+0
−0

Consider a world in which time travel has been made viable possibility. Initially, many are ecstatic at the new technology and the knowledge it will unlock. However, biologists and other scientists soon come forward to warn about time travel.

The danger is bacteria. Due to our rapidly developing antibiotics, bacteria have evolved over time to combat our medicine. Were we to travel forward, we would likely contract a deadly mutation of a bacteria from the future and spread it to the present upon our return (thus killing everyone). Were we to travel backwards, we would bring our present evolved super-bacterias to the past, which would infect the then not-vaccinated population (thus killing everyone).

How would we be able to enjoy the gift of time travel without wiping out humanity?
