You\u2019re time traveling right now into the future. Relativity theory shows higher gravity and higher speed can slow time down enough to allow you to potentially travel far into the future. But can you travel back in time to the past?<\/p>\n<p>In this video I first do a quick review of light cones, world lines, events, light like curves, time-like curves, and space-like curves in this video so that you can understand the rest of the video.<\/p>\n<p>A space like-world line means that the object has to travel faster than light. But moving anything to the speed of light requires an infinite amount of energy to accelerate. So this is not possible.<\/p>\n<p>Going faster than the speed of light can create scenarios that allow you to travel back in time. But since this is not physically possible, we need to figure out a clever manipulation of space time. This means we have to solve Einstein\u2019s equations of General relativity.<\/p>\n<div class=\"more-link-wrapper\"> <a class=\"more-link\" href=\"https:\/\/lifeboat.com\/blog\/2021\/11\/how-we-could-time-travel-through-a-special-black-hole-back-to-the-past\">Continue reading \u201cHow we could Time Travel through a (special) black hole \u2014 Back to the PAST!\u201d | &gt;<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Get your SPECIAL OFFER for MagellanTV here: https:\/\/try.magellantv.com\/arvinash \u2014 It\u2019s an exclusive offer for our viewers!
