Is it possible to bend time

Perhaps, one day, we will be able to manipulate spacetime in a similar manner. So while wormholes remain theoretically possible and important steps are being made, wormholes in spacetime, specifically, have yet to be observed or created. Another potential method of time travel is time dilation. This happens because time moves slower for objects that are near strong gravitational fields such as Earth than for objects further from these fields, like the ISS.

If you could get close to a black hole, because there are such strong gravitational forces in the vicinity, time would slow to a mesmerizing degree. Thousands of Earth-years might pass by while only a few seconds tick by near a supermassive black hole. Time dilation also comes into play where speed is concerned. So again, thousands of Earth-years could pass by in what the traveler experiences as just a few moments. And this is just the beginning, as there are a number of different ways in which we could make time travel into a reality.

Scientists from various disciplines are investigating different methods for us to make more dramatic jumps through time, l ike using circulating light beams, which can be created through the use of gamma and magnetic fields to twist space and cause time to be twisted. Other methods include quantum tunneling and hypothetical cosmic strings. At least, not yet. Einstein's theory of relativity says that space and time are linked together. What does this mean for time travel?

Well, according to this theory, the faster you travel, the slower you experience time. Scientists have done some experiments to show that this is true. For example, there was an experiment that used two clocks set to the exact same time. One clock stayed on Earth, while the other flew in an airplane going in the same direction Earth rotates. After the airplane flew around the world, scientists compared the two clocks.

The clock on the fast-moving airplane was slightly behind the clock on the ground. So, the clock on the airplane was traveling slightly slower in time than 1 second per second. We can't use a time machine to travel hundreds of years into the past or future. That kind of time travel only happens in books and movies. But the math of time travel does affect the things we use every day.

For example, we use GPS satellites to help us figure out how to get to new places. Check out our video about how GPS satellites work. But did you know that GPS relies on time-travel calculations to help you get around town? GPS satellites orbit around Earth very quickly at about 8, miles 14, kilometers per hour.

This slows down GPS satellite clocks by a small fraction of a second similar to the airplane example above. GPS satellites orbit around Earth at about 8, miles 14, kilometers per hour. Credit: GPS. Connect and share knowledge within a single location that is structured and easy to search. I heard that space can be bent by mass, that's not what I'm asking about. My question is, is it possible to bend space directly by applying force?

Example 1: I took 10 equal plastic rods, and connected them by strings in form of 4d simplex 5 vertices, each vertex is connected to each, by exactly one rod. When I pulled the strings strongly, joining all the joints together, rods bent. That's because 3 dimensional space is too small for equilateral 4 dimensional simplex, so in order to fit into 3D space, my simplex had to deform.

Example 2: Let's throw a strong rope into a wormhole, make a knot like a lasso, and pull the rope. Will the space shrink? Exerting a distinct force will not bend spacetime as an effect, it is more accurate to say that the bending of spacetime is a force - the force of gravity. For example the LIGO gravity-wave detector simply detects the effects of the tiny distortions in spacetime which are the gravity waves rippling past.

If you want a rod to bend spacetime, you just have to make the rod extremely heavy. If you loop a cable made of unobtainium through a wormhole it will come out at a very different time from when it went in.

If it actually means anything to grasp both ends at the same time, when you pull you will simply tension the cable and not affect the wormhole at all.
