What are some proposed means of interstellar travel?

Because the stars are so far apart, the proposed means of interstellar travel either includes very long ways or a very fast way to get there. We will focus on fast resources because no one likes to wait long for it to get to the destination.

There are four possible means of interstellar travel that resists seriously. They are nuclear pulse drive-one of the first proposed fusion missiles, light sails powered lasers and antimatter-based tarpaulin. Of these, it seems that the drive of antimatter and light sails seem the most promising because they are the fastest. Antimatter or light sails could achieve at speeds similar to speed of light, use the relativistic effect of time dilatation, which could cause interstellar journey to Alpha Centauri, four light years away, it seems less than a year.

The remaining methods of interstellar travel, nuclear pulse drive and fusion missiles are limited to speeds of about 10% Thna lighton Max, which makes them less interest. However, the nuclear pulse drive is interesting because it has been in our grasp since 1945. If the aggressive nuclear space program was monitored in the 1950s and 1960s, humanity could probably send expeditions with the crew to the outer solar system. However, nuclear explosions are forbidden by current international law and the Universe Treaty prohibits the deployment of nuclear weapons in space.

One of the biggest requirements for interstellar travel is the ability to slow down as soon as you reach your target star system. At speeds close to light speed, the process must be braked in about half of your journey. One of the most discussed methods of interstellar travel - light sails accelerated by huge space lasers - would have to wrap some nuclear bombs, fusion reactor or antimatter, on Ensure that they have the means to slow downLoading of the goal. Drugs may be enough for probes, but for serious colonization efforts, the ability to hinder the necessity.

One of the dead but famous ideas for interstellar spacecraft is Ramjet Bussard, which would suck and then burn interstellar hydrogen with a gigantic shoulder blade, allowing him to bypass his own fuel. However, the following calculations found that the shoulder blade would not be practical - the thrust would exceed its move.
