Scientist: Aliens May Harness Stars to Avoid Universal Expansion
The universe is expanding quickly. So, quickly that if we don’t do something, our galaxy will get left behind, as dark energy pushes us further into the infinite abyss. Luckily, this won’t happen for billions of years, but in the meantime, we may be able to find evidence of advanced alien civilizations that are planning for this catastrophe by harnessing the energy of neighboring stars.
At least that’s according to a new paper, published by senior scientist Dan Hooper at the Fermi National Accelerator Lab at the University of Chicago, proposing that we look for signs of an advanced extraterrestrial civilization pulling stars toward their home galaxy. Why? So, they can prevent themselves from being forever lost in the cosmic expansion.
Hooper’s theory is based on the hypothetical Kardashev scale, which laid out a series of technological advancements that delineate how advanced civilizations may progress. We currently sit below a Type I, unable to harness all of the energy on our planet, but hopefully we will someday move on to a Type II, in which we will be capable of harnessing the energy of our home star, the Sun.
But if there are other, older civilizations in the universe that have had a million more years of advancement, they may already be harvesting the energy of other stars in their galaxy and thinking about preventing their galactic isolation. This is the Type III civilization.
If that’s the case, these solar harvesters might leave evidence of their work in the night sky through light signatures or fluctuations, showing them dragging stars across the sky or through evidence suggesting a controlled depletion of a star’s energy.
Hooper imagines that these civilizations would, “use the energy that is harnessed to accelerate those stars away from the approaching horizon and toward the center of the civilization.”
Astrophysicists are still confounded by dark energy, having been unable to pinpoint and define precisely what it is. Dark energy is hypothesized to permeate all of space and is thought to be responsible for the expansion of the universe into the unknown.
Within 100 billion years, all stars beyond our Local Group will be pushed away, beyond the cosmic horizon, to the point they will no longer be visible from Earth. The same expansion will eventually happen to other galaxies and superclusters throughout the universe, unless a massively powerful force is able to prevent it.
So, if we’re able to get past the petty problems we currently face on Earth, in which we’re the biggest threat to our own survival, we’ll inevitably face larger issues, like getting lost in the depths of space.
In this episode of Deep Space we explore the potential evidence of advanced extraterrestrial civilizations forming a Dyson Sphere to harness the energy of stars:
NASA Announces How It Will Report ET Contact
NASA Chief Bill Nelson says looking for extraterrestrial life is part of NASA’s mission, as its top scientists call for a detailed system for classifying ET life.
In a huge departure from the US government’s historical treatment of UFOs and possible ET life, NASA administrator Bill Nelson said in an interview with University of Virginia professor Larry Sabato, “[W]ho am I to say that planet Earth is the only location of a life form that is civilized and organized like ours?”
Meanwhile, top NASA scientists are calling for a scaled system for reporting any evidence of extraterrestrial life modeled after NASA’s progressive scale of Technological Readiness Level already in use for new spaceflight equipment.
Instead of the binary “life or no life” way of looking at off-planet discoveries, these scientists are suggesting a more nuanced way of reporting what they find. Cheryl Costa, retired journalist, UFO statistician, and author of the UFO Sightings Desk Reference, thinks it’s about time.
“I think it’s long overdue, they’ve been talking about this stuff for years. They know that there have been unidentified things in our skies since biblical times,” Costa said. “The fact that they’re finally owning up to the idea of classifying alien life. Their scale is going to have to run the range of organic molecules all the way up to sentient beings, so it needs to be a pretty big scale, and it’s nice to start seeing bonified scientists looking at this issue and saying ‘OK, we need to do this.'”
And what about NASA Administrator Bill Nelson’s comments?
“I think it’s refreshing that the NASA chief came out and said ‘Yeah, maybe’ on the UFOs and off-world life. I think they still know more than they’re telling us. I’m happy NASA is coming out with this stuff, I think they’re trying to feed it to us a little spoonful at a time. They don’t want to scare the populace,” Costa said.
