Interstellar's Display of a Wormhole and the Physics Behind It

Image
The movie Interstellar displayed many astrophysical phenomena of which had barely ever been displayed in major motion pictures before. In able to gain a good foundation for the physics behind wormholes, I read chapter 14 and 15 of the book The Science Behind Interstellar  by author Kip Thorne. The wormhole displayed in the move was what Thorne referred to as a "traversable wormhole". A traversable wormhole's properties that make it different than a normal one is that it contains exotic matter. A traversable wormhole can most likely only be created unnaturaly. This is because the only exotic mater that humans have ever encountered is when we created it in a labratory. Spacetime is converged when seen from outside of the wormhole, but diverged when seen from inside the wormhole. A simple mass will cause spacetime to be converged, such as the top of Figure 1, but the divergence of spacetime requires a negative mass, or negative energy, in accordance to Einstein's ...

Top Ten Examples of Bad Astronomy vs. The Martian

Image
     The film industry is notorious for defying the laws of physics, especially the laws of space physics. In  an effort to make scenes more action filled or possibly due to lack of physics knowledge, film makers will give space certain properties and characteristics that it does not possess. Philip Plait, also  known as "The Bad Astronomer", wrote a list named "Top Ten Examples of Bad Astronomy in Major Motion Pictures" which lists the ten most common mistakes that Hollywood movies make in displaying the physics of space.      I put the movie "The Martian" to the Bad Astronomy test and chronologically noted each time the movie tested an example that Philip Plait provided in his list. The first Bad Astronomy example that the movie tested was the fourth one, which speaks about the properties of light and lasers in space.      Philip Plait claims that movies wrongly show light propogating space as though space is filled with...

The Twin Paradox vs. Contact

Image
     The movie Contact makes an effort to display a realistic representation of the Twin Paradox, but the fundamental concept of time dilation was displayed incorrectly. The time dilation in the twin paradox is a result of the point of view of a stationary observer seeing a clock move slower as it moves with a constant velocity past them. This can be portrayed in the diagram below:      Keep in mind that light in a vacuum will always travel at the speed of light [c], which represents the second postulate of special relativity. The second section of the illustration above represents the actual motion of a photon in both a moving inertia frame and a stationary inertia frame. The third section of the illustration represents what a stationary observer would see as the clock moves by them at a constant velocity. Notice how the distance that the photon actually travels (2d) is shorter than the distance that the stationary observer sees. To the stationary obs...
