Loading ...I am very disappointed in my then, now future! Who could have foretold how crappy our space would perform … for years and years.
How long can the riggers hold it together?
I guess Einstein thought that time travel was possible. Though not likely! 🙂

The theoretical underpinnings of time travel date back to 1905, when Albert Einstein wrote down his special theory of relativity that showed space and time are intimately linked, and to 1916, when Einstein’s general theory of relativity showed that space and time are malleable — that is, they respond to the presence of matter or energy by warping, bending, expanding, and contracting. By extension, this means if one can imagine space being filled with some exotic form of energy, then space and time could warp in a way so that time, as well as space, could bend back upon themselves like circles, allowing one to move forward in a straight line and still return to one’s starting point in both space and time.
But even after thinking about the time travel problem for more than a century, physicists haven’t advanced the ball very far. We recognize that while Einstein’s equations do allow for round-trip time travel (at least in principle), other physics considerations probably rule out creating the exotic forms of energy that would make it possible.”
