PBS Space Time Season 2017 Episode 25 The Real Star Wars
- July 19, 2017
PBS Space Time is a popular science show that covers a wide range of topics related to astrophysics and cosmology. In season 2017 episode 25, titled "The Real Star Wars," the show explores the fascinating world of interstellar warfare.
The episode begins by discussing the popular science fiction franchise Star Wars and how it has captivated audiences since the release of the first film in 1977. However, the show quickly establishes that the kind of interstellar warfare depicted in Star Wars is unrealistic and highly unlikely.
To understand why, the hosts of the show delve into the physics of space warfare. They explain that in space, there is no atmosphere to create drag, which means that objects will keep moving at the same speed until acted upon by an external force. This means that a small object such as a spaceship would be incredibly difficult to hit if it was moving fast enough.
However, the show goes on to explain that there are other factors to consider when it comes to space warfare. For example, space is not empty, but is instead filled with interstellar gas and dust, as well as radiation. These factors can pose significant challenges for any spacecraft, even if it is designed for combat.
The hosts also discuss the role of gravity in space warfare. They explain that large celestial bodies such as planets and stars have considerable gravitational fields that can affect the trajectory of objects in their vicinity. This means that a spacecraft may be able to use the gravity of a planet to slingshot around it and gain speed, or it may be pulled off course by a nearby star.
Overall, the show argues that while space warfare is certainly possible, it would be vastly different from the kind of battles depicted in Star Wars. Instead of dogfights between small, maneuverable spacecraft, real space warfare would likely involve long-range exchanges between large, heavily armed vessels. This is because in space, it is much easier to detect and destroy an incoming projectile from a distance than it is to dodge it once it is close.
Despite this, the show acknowledges that the idea of interstellar warfare is still a fascinating topic to explore. They discuss the various strategies that could be employed in a space battle, such as using decoys or jamming enemy sensors. They also discuss the potential for cyberwarfare in space, which could involve hacking into an enemy spacecraft's computer systems.
Overall, "The Real Star Wars" is an enthralling episode that offers a fascinating look at the physics of space warfare. While it may not deliver the kind of action-packed battles seen in science fiction, it does provide a thought-provoking exploration of what real space warfare might look like.
