Scientific Explanations about Aliens Existence
Many stars in the Universe
According to Seth Shostak from SETI (Search for Extraterrestrial Intelligence) Institute, there is no direct proof for any life beyond Earth, but universe is home to a lot of stars. As stimated by Shostak, there are 1 trillion planets in the Milky Way alone. He said that some of them have undergone and develped life, and eventually what we call sentient life. And if we are the only intelligent beings in the galaxy, of for that matter in the universe, we are truly a miracle (Shostak, n.d.)
One scientist thinks Aliens will need to catch stars to survive.
The future intelligent aliens can survive in the form of collecting, storing and harmessing the power of stars. As the universe continues to expand, an intelligent extraterrestrial civilization will become outlying and in need power for the next 100 billion years or more. Aliens might need to use stars as an alternative source of energy. (Hooper, 2018)
In an article at IFLScience.com, It is said that our universe is expanding because of mysterious dark energy. The major problem is that everything will spread out that no new stars can form, and the universe ends. Aside from collecting the powers of stars, aliens could survive the universe. According to Dan Hooper, They move stars closer together to prolong their existence. “In order to maximize its access to useable energy, a sufficiently advanced civilization would chose to expand rapidly outward, build Dyson Spheres or similar structures around encountered stars, and use the energy that is harnessed to accelerate those stars away from the approaching horizon and toward the center of the civilization,” (Hooper 2018)
Hooper notes that the presence of dark energy in our universe is causing space to expand in accelerating rate. As a result, most stars in other galaxies will move to other. So, It means that we won’t be able to see them anymore and wouldnlt be able to reach them. He suggest that aliens could use spacecrraft to grab stars from anywhere and bring them closer. We have no evidences that an advanced civilizations exists. He added, if aliens were aleady doing this, we will be able to spot them doing it . A lack of stars in one region could be the sign that aliens have already scoop them up personaly.
