“TIME TRAVEL IS IMPOSSIBLE!!!”
Lot’s of things are impossible until they aren’t.
“Time cannot pass backwards, or faster than it currently does.”
Einstein’s theory of relativity is a fundamental theory in physics that has been extensively confirmed through experimental evidence. One of the key insights of the theory is that time is not absolute and can be affected by factors such as velocity and gravity.
The theory of relativity contains two main components: special relativity and general relativity. Special relativity deals with the behavior of objects in the absence of gravity, while general relativity describes the effects of gravity on the shape of space and the flow of time.
Special relativity predicts that time will appear to pass more slowly for objects that are moving at high speeds relative to an observer who is at rest. This effect is known as time dilation, and it has been confirmed through a variety of experiments involving high-speed particles and atomic clocks.
General relativity, on the other hand, predicts that gravity can cause time to pass more slowly near massive objects such as planets, stars, and black holes. This effect, known as gravitational time dilation, has been observed through experiments involving atomic clocks on Earth and in space.
For example, in the famous Gravity Probe B experiment, scientists used four ultra-precise gyroscopes to measure the effects of Earth’s gravity on the flow of time. The experiment confirmed predictions from general relativity with incredible precision, showing that the flow of time is affected by gravity in the exact way that Einstein’s theory predicted.
Overall, the extensive experimental evidence confirms that Einstein’s theory of relativity accurately describes the behavior of time and space in a wide range of physical situations.
In addition, general relativity predicts the existence of “closed time-like curves,” which are paths through space-time that loop back on themselves, potentially allowing for time travel. However, it is important to note that these closed time-like curves are purely theoretical and have not been observed in the real world.
Einstein himself was skeptical about the possibility of time travel and believed that it would likely remain in the realm of science fiction. Nevertheless, the theoretical possibility of time travel under certain conditions is a consequence of his theory of relativity.
