Re: Physicist believes we will travel through time this century
The question you posed, was also asked by Stephen Hawking: “If time travel is possible, why haven’t we been overrun by tourists from the future?”
Carl Sagan probably answered this best. “We might not have seen time travel because it requires a level of technological sophistication that we may never achieve as a civilization. Effects of global warming, war or famine might just end our civilization before we ever reach the level of technological sophistication needed to create a time machine.
However, “On the other hand,” Sagan mused, if we are advanced enough to create a time machine, we should be able to have technology that would hide us from today’s world.
Forward-thinking scientists at the Cern Large Hadron Collider and in universities throughout the world believe that time travel will one day become possible. Today, it’s beyond the reach of our technological capabilities, but if and when our “magical future” arrives, and if I’m still around, I would like to be first in line to hitch a ride back to the future.
