I never said jumping to another time, it's the fact of relativity, if one object is traveling at a much greater speeds than another object, the faster object skips ahead in appearance to the slower moving object, while the faster moving object will see the slower moving object speed up in age. Take for instance, satelites, they always gain a few fractions of a second in orbit around earth compared to clocks on the surface due to the speed at which they travel compared to the speed we travel. Now if you could hit the speed of light, or go beyond that, then it is possible you can jump around any future time period of your pick, but, you have to be going fast enough, to be able to get there, while still alive, but, at those speeds, there is no known way to protect a human, yet alone, any particles that we accelerate to that speed.
I hope they find more info on dark matter, apparently since that makes up the majority of the universe, it would be the most abundant thing out there, but, we can't see it, well, we can, but we cant.
