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:

DNA Might be the Best Bargaining Chip We Have With Aliens
If we ever needed to barter with an advanced alien species, our DNA might be the best currency we could offer, according to Daniel Helman, a professor of Labor Relations and Trade Unions at Ton Duc Thang University in Vietnam.
That’s because our technology would likely be antiquated compared to theirs, making it essentially useless in trading and bargaining. But if we could give them something completely unique to our specific planet, there’s a good chance they may be interested.
Helman first proposed this idea at the International Space Development Conference, and later expanded on it in an interview with Motherboard.
Our DNA he said, is like a record of millions of years of evolution and interaction with Earth’s environment, and if we could give them mapped-out documentation of this, they may consider it useful. The Human Genome Project and other attempts to catalogue our DNA would be a good starting point to begin negotiations.
Barring the possibility these extraterrestrials might have some sort of highly advanced system to fast track DNA sequencing, we would already have a solid foundation of background knowledge in epigenetics – how the environment affects the expression of genes – and evolutionary processes that have led to most modern species on Earth.
Helman also points out that he believes our gradual destruction of biodiversity on the planet lowers the number of bargaining chips we hypothetically have to trade. The more animals go extinct, the less DNA we have – unless we start storing embryos and DNA samples in the Doomsday Vault.
Though, one concern with Helman’s idea is that giving up the building blocks to life on Earth might lead extraterrestrials to develop diseases that could wipe us out. But if they had technology vastly superior to anything we have, they would probably have the means to destroy us in a number of ways.
Essentially, the argument hinges on whether these extraterrestrial visitors are bent on conquering or making friends with us. A timeless hypothetical, but for the sake of Helman’s argument, we should consider the latter scenario.
And in the sense that our biggest obstacle to the next level of technological advancement is surviving ourselves, it’s more likely that developed alien species would lean towards the peaceful side. For us, perpetual global conflicts and the looming threat of nuclear war could be the deciding factor in whether we continue as a species that explores the galaxy or destroys itself.
So, if an alien race has advanced far enough to make it to Earth, it’s likely our global infighting and environmental destruction would look petty and archaic to them. So it might be time we develop a disruptive marketing strategy for our DNA, and prepare for an intergalactic game of poker.
