I agree with the sentiment about H2 and Ancient Aliens, and the Discovery family of channels rubbish on the same topic. But! I must point out that the speed of light does not actually prevent space aliens from reaching the Earth. It might take a generation ship to do it, or the aliens might live for thousands of years and do it in just one. But I see no evidence of alien visitation either now or in the past. I see only wishful thinking about stone-age technology.
Continuing OT:
Also, Warp Drive (yes, as in Star Trek: for the original series Gene Roddenberry had REAL scientists as technical advisers and got in touch with a lot of people at NASA and the military about coming tech, and this continued in Next Generation) is scientificly valid. With Warp Drive, the ship does not move, but rather the space around it is moved, and, therefore, speed of light restriction does not apply. Further, while in the warp bubble created by warping the space around the ship, time does NOT slow down, but remains unaffected, hence, one can effectively travel exponentially faster than the speed of light with none of Einstein Theories' limitations or effects.
In fact just about all the Star Trek tech was accepted as possible by scientists of the 1960's and today, EXCEPT for the tele-portation tech (beaming up and down). That one was dreamed up as the only cost-effective way Gene could get his characters on the surface of the planet each week. It HOWEVER, a few scientists TODAY have made some discoveries that they feel could make tele-transportation for both inorganic, and even ORGANIC matter possible some day eliminating the current laws that state that one can not re-assemble organic matter EXACTLY as it was upon dis-assembly. The computer memory required to transport a person was a deal breaker back then (they were lucky to get Kb of memory back then), but we are finding less so as we improve the great capacity of computer memory.
However, I do agree that while I do watch those "Alien" shows, I do think there are too many of them, although I like the ones that attempt a scientific explanation for what can be mistaken as UFO, etc, such as the series NASA's Unexplained Files. It's a lot like how The LEARNING Channel is all about Honey Boo Boo, or MTV is about stupid reality series' and now HISTORY, H2, American Destination, Science, etc, and we are even poaching shows from CANADA we are so desperate to make the $$$ on such shows due to their popularity, and just about all the channels now, is about Aliens. I just think we would be better served to have an "Alien Channel" channel or the "Unexplained Channel" that better reflects the content.
As for scientifically sound Warp Drive, we need a cheap way to induce matter and anti-matter to provide the massive power of the sun or a few suns and to contain that and warp space. Very challenging, but even REPUTABLE scientists say they have some optimism for it for future generations. They believe humans will solve these challenges as we have solved other technological challenges. Personally, it may take a hundred or so years to achieve it just as Roddenberry put his characters 200 years in our future.
Live Long and Prosper.
