Gliese 581D
The closest planet known as the big, rocky and Earth-like. The planet can be a similar one, the nest of human race in the future. A second shelter in the unforgiving darkness of Uzay was discovered in 2007. It is exactly 7 times bigger than the earth! it is smaller and redder than our sun, but it is at the right distance for water to be on the surface in liquid form. Gliese seems to be a perfect "new world", but it has a serious problem that we have to come from above.
Gliese is far from us, far away from the world, more than 20 light years away! This is about 190 Trillion Kilometers. Let's think we have the fastest car made by human ırkı to have an idea about distance; Voyager1.
He was 30 years old and was 18 billion miles long. The mission delivered it to Jupiter and Saturn. Using the gravity of these planets, this small spacecraft was able to record a record. It is about 64,000 kilometers. This speed can travel the world 1.5 times in 1 hour at this speed.
So how long will it take for a space vehicle like Voyager to reach Gliese, the nearest Earth-like planet? ... The answer reveals the magnitude of the universe. Even if we travel at 17 kilometers per hour, the trip to Gliese will take more than 350,000 years. But in order to do this, we need to develop new technologies in gigantic dimensions. Today engineers think how to make such a vehicle. What is necessary for this vehicle is that it can be provided with energies that can not be ignored with more exotic fuel such as Atom Energy or anti-matter. But I do not think that the real problems will be technical subjects. , first the problems will be financial. Producing a new spacecraft can reveal huge costs, and it is not a guarantee that those who make it will be able to pay for their labor. Let's say the vehicle is 1000 times faster than Voyager, and the journey will still take 73 years.
