According to Einstein’s theory of general relativity, big objects with lots of gravity — planets or stars — bend the fabric of time and space, like bowling balls on a trampoline. The closer you get to these objects, the stronger the pull of gravity and the slower time moves. An astronaut watching a clock fall into a black hole, for example, would see its hands gradually slow down as the pull of gravity increases. The second hand would move tick once every hour, then once every decade, and finally appear to stop altogether.
That being said the further away from the center of the Earth I place myself the slower time moves for me, and in theory the more time I would have to spend with my family and/or doing things that I want to do. The “Einstein Tower” was a vain attempt at capturing this trick of time/space to lengthen my time on Earth.
