Have you ever seen science fiction movie about teleportation or time travel before? You wonder if those machines can be invented in real life based on the laws of physics. Well, it is true that it has scientific basis. It is just, it has not achieved yet. However, the scientists keep working on it. One invention that they are really working on these days is antimatter spacecraft. It is used to shorten the journey to the outer space. For example, if previously, it needs 11 months to reach Mars, it will only take one month with the antimatter spacecraft. It means that the engine can take us to go many times faster than the current propulsion methods allow. An antimatter spacecraft can take us far beyond our solar system and reach nearby stars in shorter time than a spacecraft with liquid-hydrogen engine. |
