Spaceships Faster Than Speed of Light
Spaceships Faster Than Speed of Light. The idea that characters can fly from planet to planet, or star to star, defying current science and technology, is central to science fiction. Although some of these ideas predated the space age, after the 1950s, fictional depictions of space travel needed to suggest conceivable ways to cross interstellar distances to seem plausible. Some authors suggested faster-than-light drives, jump drives, wormholes, and black holes. But would it be possible for spaceships to travel faster than the speed of light? In this video we are going to take a closer look into what the physicists are saying on this subject.
In Issac Asimov’s ‘Foundation series,’ humanity can travel from planet to planet, star to star or across the universe using jump drives. Some characters, like the astronauts in the movies “Interstellar” and “Thor” use wormholes to travel between solar systems in seconds. Another approach, familiar to “Star Trek” fans, is warp drive technology. Warp drives are theoretically possible if still far-fetched technology. According to physicist Albert Einstein’s general theory of relativity, on which much of modern physics is based, nothing in the universe can travel faster than light. The theory states that as a matter approaches the speed of light, that matter’s mass becomes infinite. That means the speed of light functions as a speed limit on the whole universe. The speed of light is so immutable that, according to the U.S. National Institute of Standards and Technology, it is used to define international standard measurements like the meter, and by extension, the mile, the foot and the inch.Einstein’s theory also describes how mass and energy warp spacetime, hefty objects like stars and black holes curve spacetime around them. This curvature is what you feel as gravity and why many spacefaring heroes worry about “getting stuck in” or “falling into” a gravity well.
