Game Changers

Each one of these rings holds spirits. Along with that they hold Tesla energy to help them manifest as well as take direction. There is no need to wear these but you can if you want to. The spirits were picked for various reasons. To get them working for you all you need to do is hold them for a short while or wear. Your body heat is energy and your energy gets synthesized to mesh with what you need. Along with that comes one of these. All of these spirits can move through time, forward and backwards. Usually they are either stuck in our time now or can view the past but not change it, these can. These are extremely different and beneficial to you. You may pick the spirit you want or go with one we have. 
We have so far the following list available. John Dee, Tesla, Edgar Cayce, Einstein, Croesus, Mayer Amschel Rothschild,Mansa Musa, Marilyn Monroe, Natalie Wood, Peter Higgs, Alain Delon.  These are a few we have now but you can pick who you want.
Below is a list of time travel types and ways. These spirits have cultivated these ways of travel and can use them to change things, see things and prepare for various situations. All of the spirits are highly intelligent, creative and wealthy. Many were trained in the arts or sciences.  These are definitely game changers because they can definitely help you. Also when you hold one of these rings the energy you get can charge your other items using your own hands. While these were not costly to make they are time consuming. You have to have willing spirits and these definitely are for various reasons of their own. 
1. Wormholes. General relativity suggests that space-time could be curved in such a way that distant points are connected by a shorter path, known as a wormhole. If traversable wormholes exist, they could theoretically be used for time travel by moving one end at relativistic speeds or placing it near a strong gravitational field, creating a time difference between the two ends.
2. Cosmic Strings. These are hypothetical, extremely thin, dense, and incredibly long structures that might exist in the universe. If two cosmic strings pass close to each other at near the speed of light, they could warp space-time around them enough to allow for time travel into the past.
3. Black Holes. A concept known as the "Kerr black hole" theory suggests that if a black hole is rotating, it might be possible to travel through it without being crushed by its singularity. This could, in theory, lead to another part of the universe or perhaps even to a different time due to the extreme gravitational time dilation effects.
4. Time Dilation via Speed.According to Einstein's theory of special relativity, time dilation occurs when traveling at speeds close to the speed of light. An astronaut traveling near light speed would age more slowly than someone on Earth. While this isn't time travel in the classical sense, upon returning, the astronaut would find themselves in the future relative to when they left.
5. Gravitational Time Dilation. Strong gravitational fields slow down time. Near an incredibly massive object, like a neutron star or a black hole, time would pass slower compared to a place with weaker gravity. This isn't practical for time travel but illustrates how gravity can affect time.
6. Tipler Cylinder. Proposed by physicist Frank Tipler, this would involve an infinitely long, extremely dense cylinder spinning at high speeds. If built, it might allow for time travel by following a spiral path around the cylinder that leads back in time.
7. Quantum Mechanics and Closed Timelike Curves (CTCs).Some interpretations of quantum mechanics and solutions to general relativity (like those proposed by Kurt Gödel) allow for the existence of paths in space-time that loop back on themselves. If one could travel along such a curve, they would theoretically end up in their own past.
8.Philosophical and Multiverse Approaches. Some theories suggest that every moment in time exists simultaneously in different branches of reality or universes. Time travel could then be about moving between these branches rather than traveling along a linear timeline.
