The Interstellar Race: Who Will Reach Alpha Centauri First?
851Can you imagine what the spaceships of the future will be like? Imagine that spaceships will use nuclear energy as fuel in the future! Would those spacecraft be fast enough to reach the closest star to the Sun? And if so, who will go aboard those spaceships? Who would be the first to reach Alpha Centauri?
Currently, spaceships, even humanity's most advanced and powerful, have many problems getting out of the solar system.
This is mainly due to two factors; the first is that the universe is vast, it is immense, and the distances that separate all celestial bodies are so enormous that they cannot be measured in kilometers but rather in astronomical units and light years.
An astronomical unit is the average distance between the Sun and Earth, equivalent to approximately 92.96 million miles (149.6 million kilometers).
The problem of going out
To date, no human-created spacecraft has managed to leave the solar system.
Technologies that already exist
In past videos, we have talked about the different technologies that could exist in the future to travel to Alpha Centauri. However, most of them remain in speculation as they do not exist yet.
Temporary dilation
Time dilation is a phenomenon that arises from Einstein's theory of relativity; in simple terms, it means that time can pass slower or faster depending on the speed and gravity in which you find yourself.
What technology will be chosen?
That said, considering the trip to Alpha Centauri will take more than 80 years, what technology would be chosen to do it?
1. Nuclear Fusion Propulsion
Nuclear fusion propulsion is a space propulsion concept based on the use of energy generated by controlled nuclear fusion.
2. Nuclear Pulse Propulsion
Pulse nuclear propulsion, also known as pulsed nuclear explosion nuclear propulsion, is a space propulsion concept that involves using controlled nuclear explosions to generate impulses and propel a spacecraft.
3. Solar sail propulsion
Solar sail propulsion is a theoretical space propulsion method based on harnessing the pressure of solar radiation to propel a spacecraft. It uses a very light and large sail or reflector, known as a solar sail, which reflects solar radiation.
4. Laser propulsion
Laser propulsion is a space propulsion concept that relies on using a high-powered laser beam to propel a spacecraft.
