As I have said previously if you remove time creating a timeless universe then time travel could become a reality.

Well now I’m going to look at the speed of light and its role in time travel theory.

During the final part of the 20th century and into the 21st century scientists have been doing experiments concerning Bose-Einstein Condensates.

These condensates are created by cooling atoms and taking their temperature to absolute zero. Their existence was first theorised by Albert Einstein and Satyendra Bose in 1925, but their theories could not be tested at the time because there was no technology advanced enough to do so. It was not until 1995 seventy years later that their theory was actually proved in an experiment at the University of Colorado at Boulder NIST-JILA lab by Eric Cornell and Carl Wieman. They cooled rubidium atoms down to 170 nanokelvin creating a huge cloud of gas with an undefined size and shape and properties and behaviors that are currently not completely understood.

What Does this have to do with Time travel?

When you cool things down to absolute zero all motion stops so the particles making up an atom will have no velocity, meaning momentum will be zero.

In later experiments scientists shone light in to the cloud to see what would happen. In the first known experiment of this type the light’s speed was slowed from its normal 186,000 miles per second down to a crawl of 38 miles per hour as it moved through the cloud of the condensate.

The slowing of light is the first step in defeating the time barrier and the Bose-Einstein condensate could be the first step to creating a working time machine.
