Very well compiled and really intresting.
In fact, in India mythology, there are very interesting stories on time travel.
By reading the article, especially the Einsteen's theory, I recollected one of the stories related to King "Kakudmi"

Revati was his Daughter and was so beautiful that when she was at marriageable age, Kakudmi, the king, thinking no one upon earth was worthy enought to marry her and went to the Creator himself, Lord Brahma, to seek his advice about a suitable husband for his daughter.

When they arrived, Brahma was listening to a musical performance, so they waited patiently. After the performance was finished, Kakudmi made his request and presented the list of his shortlisted candidates.
Brahma laughed loudly, and explained that time runs differently on different planes of the existence. During that short time of musical performance, 27 chatur-yugas (a cycle of four yugas, totalling 108 yugas, or Ages of Man) had passed on earth.

Brahma said to Kakudmi, "O King, all those whom you may have decided within the core of your heart to accept as your son-in-law have died in the course of time. Twenty-seven chatur-yugas have already passed. Those upon whom you may have already decided are now gone, and so are their sons, grandsons and other descendants. You cannot even hear about their names.
