Answer to Question 1
Present rockets operate through chemical reactions, i.e., ordinary burning, which is a relatively inefficient process. To achieve high speeds requires lots of additional fuel, but the added weight of the fuel makes it more difficult to increase the rocket's speed. Such chemical rockets therefore have a fundamental limit to their speed and can go no faster than about 0.1 percent of the speed of light, which is not enough to reach the nearest stars (more than a light year away) in less than 1000 years.
Answer to Question 2
