Einstein and Time Travel

For Einstein's 70th birthday, mathematician Kurt Gödel reportedly gifted him a sweater along with a paper that proposed a proof of time travel. While the existence of the sweater is debated, Gödel's reasoning used Einstein's theories, suggesting that by traveling in a high-speed rocket along a curved path, one could theoretically return to an earlier point in time. However, the flaw in Gödel's logic was based on the assumption that the universe rotates, which scientists later disproved. This connection between two great minds highlights the intricate relationship between mathematics and physics, as well as the emotional implications of Gödel's theories, which he often shared with Einstein over the years.
