• Renowned American astrophysicist Ethan Siegel says that humans are running out of time to contact extraterrestrials. Seigal reasons that since our universe is rapidly expanding due to the anti-gravity properties of dark matter, and the rate of expansion is increasing. For this reason, Seigel believes that contacting aliens in nearby galaxies should be made as soon as possible, or else we will lose our chance.
• “As the universe continues on into the future, all the galaxies that aren’t part of our local group will accelerate away from us, owing to the presence of dark energy. By the time the universe is an age of 100 billion years or so, the nearest galaxy to us will be about a billion light-years away,” said Seigel. Galaxies close to us will therefore be twice as far away when the universe becomes double its current age.
• [Editor’s Note] Physicists such as Ethan Seigel make these claims under the premise that our current knowledge of astro-physics is all there is to know about space. This is simply not the case. It was recently revealed and reported that U.S. military intelligence is actively studying alternative advanced methods of propulsion such as wormholes and anti-gravity. The speed of light is not a barrier to future space travel. And since we can travel from one end of the galaxy to the other in relatively short time periods now, it won’t make much of a difference as star positions, galaxies and universes continue to expand.
Ethan Siegel, renowned American astrophysicist has revealed that humans are running out of time to contact extraterrestrials because our universe is rapidly expanding. As per Seigel, if humans do not make contact with aliens in the near future, then contacting aliens will become a practically impossible task.
Experts believe that it is the presence of dark matter which helps the universe to expand. Dark matter is believed to have anti-gravity properties, it reduces the gravity which holds together different galaxies. As gravity decreases between galaxies, the rate of expansion speeds up and that will make interstellar contact impossible in the future.
“If a far-future civilization were to look beyond our own future galaxy, they’d see… nothing. As the universe continues on into the future, all the galaxies that aren’t part of our local group will accelerate away from us, owing to the presence of dark energy. By the time the universe is an age of 100 billion years or so, the nearest galaxy to us will be about a billion light-years away,” said Seigel, Express UK reports.
