Submission + - Time Travel in our lifetimes? (decodedscience.com)

Einstein showed that mass and energy are the same thing. The time machine we’ve designed uses light in the form of circulating lasers to warp or loop time.
In Einstein’s theory it turns out that not only matter such as the Earth can create gravity but also light. It is the energy of light that creates gravity. Consequently, since time is affected by gravity and light can create gravity due to its energy then light can also affect time."
