Tipler Cylinder

Recommended Posts

I have recently heard of something called a Tipler cylinder, which allows time travel to the past.

How is it possible for something to create time travel to the past, according to our current understanding of general relativity?

Time is dilated by a factor of

[latex]\frac{d\tau}{dt}=\sqrt{g_{00}}[/latex]

in general relativity, so how is it possible to make the factor negative?

A Tipler cylinder, also called a Tipler time machine, was a hypothetical object theorized to be a potential mode of time travel—although later results have shown that a Tipler cylinder could only allow time travel if its length were infinite or with the existence of negative energy (see the discussion of Hawking's proof below).
