Since ancient times, men have gazed upon the cosmic ocean above our heads wondering what could be out there. In the last 2 centuries human kind has made a huge leap in technology and science, from horse drawn carriages to spaceships capable to send us into space. What used to be considered science fiction now is considered science fact. In 1969, Apollo 11 was the first manned mission to land on the moon, opening the path towards the stars. One problem that we encounter is distance. The closest star to Earth, beside the Sun, is Alpha Centauri B, being situated at 4.24 light years away. This means if we were traveling at the speed of light, we would need 4 years to get to the star, but the fastest man-made object is the Voyager 1, a space probe launched by NASA in 1977, reaching the speed of 17 kilometers per second (compared to 300,000 kilometers per second, the speed of light). This means it will take over 74,000 years to reach Alpha Centauri B. In order to reach stars in a more effective way, we need to reach higher speeds.
According to Einstein’s theory of relativity nothing can travel faster than the speed of light. This is because the mass of an object that is moving with the speed of light is becoming infinite, requiring infinite energy to propel it, which is obviously impossible. Even at 80% of the speed of light, mass is becoming a big problem.
One day, in Earth’s distant future, there will be a “Last day of the Earth” scenario. Eventually, the sun will become a…
