Remember that 1960’s sci-fi masterpiece—the original Planet of the Apes? In that now cult classic film a group of astronauts travel to Earth’s distant future where “apes rule!” While there, Charlton Heston chews up the scenery and, more importantly,
shows us a pretty good example of how Einstein’s theory of special relativity makes space travel a challenge. In the film the astronauts have been traveling for one and a half years in their frame of reference; meanwhile 2000 years have elapsed on Earth. According to the rules of special relativity this is a realistic scenario. But how can this be? It’s actually a natural consequence of the observation that the speed of light (c) is constant regardless of the frame of reference from which you measure it. Through a series of logical steps Einstein reasoned that this means that the amount of time that passes between events depends on the frame of reference from which you observe them.
According to special relativity anything with any mass will always travel less than the speed of light, but if you get close enough then time dilation starts to rear its (ugly?) head. The time dilation equation can be expressed as follows:
Tship = Tearth(1-v2/c2)1/2
(Using the above equation you can show that the ship must have been traveling at an average speed of v = 0.9999997c relative to Earth to achieve this amount of time dilation.)
So while it’s theoretically possible to get places somewhat quickly in your spaceship if you travel close enough to c, when you arrive at your destination you’re hardly going to agree on what time it is, what year it is, or who’s the president. Your children may well be older than you when you get back. This could be extremely inconvenient, to say the least.
Anything that interests people in wanting a better understanding of science is priceless, and for the nation eventually improves our competitive position, compared to the rest of the world. I don't care if it's movies, TV shows, or newspaper articles, bring it on.
Very interesting article here. I've read up on all these things and so it was nothing new for me, but It was cool to read. Afterall, I had never heard of that Event Horizon; they enter some dimension or other universe of pure chaos? In real life I doubt they would have survived that. ;)
I'm a bit surprised you did not seem to know the explanation for jump drive. As far as I know, BSG has never explained it and thus I don't blame you in that sense, but jump is seen in other scifi universes and is always fairly consistent. Though I believe it's in anime too, the scifi universe I know personally is the BattleTech universe, which is what games such as MechWarrior and MechAsssault are based on.
Although mind-boggling how we could ever make this possible with technology, especially due to the Uncertainty Principle, jump drive works by causing every particle of the ship to jump to another location in the SAME WAY that an electron jumps and disappears as it approaches an atom's nucleus, and reappears on the other side, and the continues to follow its orbital. It is sometimes thought of as "phasing" into the other location, thought if could also be considered as using another dimension for travel, and thus be a form of hyperspace.
Due to this, depending on the scifi universe, exact destinations can never be ascertained. Compared to battletech, BSG can do presicion jumps; in BattleTech, you would NEVER have a fleet jump; only one ship will do it, with the destination clear. In BSG at least, the farther the jump, the less precise it is. In BattleTech, misjumps are common. Usually it means nothing more than arriving a bit farther away from your destination, but in other cases, you may end up lightyears away, jump into a heavily trafficked route, or in one famous case, the computer failed to abort the jump in time, so that the ship was stopped mid-jump and stuck there for 250 years. It took 250 years for natural quantum and gravity fluctuations to tip the scale and cause the ship to finally phase completely at its destination. The crew had a big shock when they discovered 250 years had passed, when it had felt to them like an instataneous jump.
An episode of BSG, in 2nd or 3rd season, showed just what can happen when the risk is taken to jump too close to existing matter. A fleet of Raptors jumped to explore a distant planet (what became New Caprica, was it?). All arrived dangerously close to the planet; one of them, sadly, jumped into a mountain. Of course that meant, if you were to examine the site, the ship and bodies of the two aboard were fused within the rock of the mountain.
