Time travel is possible. In fact, you’ve been doing it since the day you were born. But what if we told you there’s a way to hack the universe and manipulate time itself?
We just have to do two simple things to make it happen:
1. Make a lot of physicists grumpy.
2. Shoot one twin through space against their will, while the other chills on Earth.
Let’s go!

    Well, the speed of light is the fastest to our dimension only but the upper ones is normal or even slower.
    According the messenger journey with the angel in Quran, it seems the speed he travelled with according to the distance he acrossed was far beyond the human imagination; means way faster than light multiple times.

    We have never time traveled backbirds and the amount of energy that it would take to do so would be more than the energy from the big band the device that you'd have to put that energy in would have to be bigger than that amount of energy because in science the laws of thermal dynamics. Always apply. You can never have more energy coming out of the system. Then you put in and there's always going to be energy loss. So even if it works on paper it will never work physically. Hypotheticalized this and saved, we look faster and we've give them out. They made the machine. The Earth's traveling through space at hundreds of millions of miles an hour. Even if we went back in time, they would bloop into a piece of space where the Earth hasn't made it to yet, it would be an empty piece of space with no oxygen lots of solar radiation and it would be below 0 absolute zero. You cannot go backwards in time even if it's possible. You guys are so dumb. You don't take an account all of the constants that are going on around you. It's fucking impossible

    It makes sense.
    Quantum particles are uneffected by time and space because they exist just outside of our spacetime universe.
    Quantum particles are sentient and perceive the entire procession of space and time in our universe, from the beginning to the end, but they cannot change anything about it because everything within our spacetime universe has already happened.
    From the perspective of our subluminal consciousness, the procession of time and space is still happening because we are moving slower than our superluminal selves, (our souls)
    We are the quantum particles outside of the spacetime universe, looking in at our own past, present and future.
    You remember the past because you've already been through it. You can't remember the future because you haven't passed through it yet, and you don't recognize your quantum self, because you're still passing through spacetime.
