Eps 1: time travel
In the podcast on time travel, the hosts discuss the idea of time travel, explaining that while it is popular in science fiction, it remains firmly in the realm of fantasy. They discuss the concept of the time-space continuum and the problems related to changing the past or visiting parallel universes. They explain how Einstein's theory of relativity allows for the possibility of time travel, but only in theory. They also examine common time-travel tropes in popular culture, including meeting oneself in the past and the butterfly effect. The hosts conclude by noting that while time travel may not be possible, the topic remains fascinating to many people.

The concept of time travel is based on the idea that time is a dimension, just like length, width, and height. If time is a dimension, then theoretically, it should be possible to travel through it just like we travel through space. However, the laws of physics as we understand them today seem to suggest otherwise.
The most famous theory of time travel is Einstein’s theory of relativity. This theory states that time and space are intertwined and that they are affected by gravity. According to the theory, if a person were to travel close to the speed of light, time would slow down for them relative to someone who was not traveling at such a high speed. This phenomenon is known as time dilation.
The idea is that if a person were to travel at a speed close to the speed of light for a number of years, when they returned to Earth, they would have aged much less than their counterparts on Earth. This means that time has effectively slowed down for the traveler. However, this would only allow for travel into the future and not into the past.
Traveling into the past is where things get even more complicated. The most famous paradox associated with time travel into the past is the grandfather paradox. This paradox suggests that if a person were to travel back in time and kill their grandfather before they had a chance to have children, then the person traveling back in time would never have been born. This would create a paradox because if the person was never born, then they could not have traveled back in time to kill their grandfather.
This paradox highlights the logical inconsistencies that arise when dealing with time travel into the past. It seems to suggest that time travel into the past is simply not possible. However, there are some theories that suggest that it might be possible under certain conditions.
One such theory is the concept of a wormhole. A wormhole is a hypothetical tunnel connecting two points in space-time, which could theoretically allow for travel through time as well as space. However, the existence of wormholes is still a matter of theoretical physics and has not been proven to exist.
Another theory of time travel into the past is the concept of closed time-like curves. Closed time-like curves are paths through space-time that allow for travel into the past. However, the existence of closed time-like curves is still a matter of debate among scientists.
Despite the theoretical hurdles, the idea of time travel continues to fascinate and captivate the minds of people around the world. The fact that it is not yet definitively proven to be impossible means that the human imagination is free to explore the possibilities.
In conclusion, time travel is a fascinating concept that has been explored extensively in popular culture over the years. While the laws of physics as we understand them today seem to suggest that time travel into the past is not possible, the concept continues to be explored by scientists and theorists. It may be some time before the true realities of time travel are uncovered, but in the meantime, the possibilities and potential of time travel continue to be explored in the realm of science fiction.
