Scientists have discovered the neutrinos travel faster than light. Travel faster than light is a prerequisite of time travel. Ergo it is possible at some time in the future that time travel will be commonplace.
Forget all that, if you want to time travel visit a restaurant, deli or some other place where sights, sounds and smells remind you of a time long ago. This aspect connection is lost on most people who operate these venues. To them it is another day in the salt mine. To the customer it is the creation or the reliving of a treasured memory.
Go back in time today and enjoy.
