Define Tipler machine

Tipler machine: The solution to Einstein's equations of general relativity which permits time travel. A tremendously dense (that is, on the order of the density of neutron star matter), infinitely-long cylinder that rotates very quickly can form closed time like curves in its vicinity, that will permit time travel and possible succeeding violations of the causality.
