We May Have Discovered an Alien Civilisation!

Postby Summerlander » 17 Oct 2015 22:29

We may have found an alien civilisation light-years away! It looks like there are intelligently built structures orbiting another star in our galaxy. This is better than finding water on Mars! If these are Dyson spheres that we have found, then the aliens are far more advanced than us--Type 2 on the hypothetical Kardashev scale.

But seen as the star the structures orbit is close to 1,500 light-years away, what we are seeing today is the distant past; the aliens could, at present, be on their way to becoming Type 3 (beginning to harness energy from the galaxy)--if they haven't gone extinct. If they ever visit our planet, they will look like gods to us. 8-)

For those who reckon this is a sensationalist headline, I invite you to read Tabetha Boyajian's data--we are talking about NASA astrophysics here--detailing rotation period anomalies of the KIC846282 system. It is no wonder that scientists are taking the alien civilisation hypothesis very seriously: Tabby star's astronomic light curve suggests alien megastructures akin to Dyson spheres--possibly something like an epic system of solar panels placed around the yellow dwarf!

Tabby's star--which is a candidate for gravitationally holding Earth-like exoplanets--is about 454 parsecs away from us and cannot be seen by the naked eye; its unusual brightness changes were first thought to be caused by disintegrated comets in orbit, however, this hypothesis is loosing its ground as the light frequencies have become oddly irregular over time. Here's an excerpt from The Independent:

'The analysts tagged the star as "interesting" and "bizarre" because it was surrounded by a mass of matter in tight formation. This was consistent with the mass of debris that surrounds a young star just as it did with our sun before the planets formed. However, this star was not young and the "debris" must have been deposited around it fairly recently or it would have been clumped together by gravity--or swallowed by the star itself.'

SETI is going to see if they can detect intelligent signals from KIC846282; taking the Drake equation into account, by the way, just because a civilisation is highly advanced doesn't necessarily mean it will have the desire to reach out to galactic neighbours. (Even if they are humanoid like us--which is a possibility considering that they would have evolved in Earth-like environments with similar Darwinian selections.)

Apparently it's most likely a "swarm of comets".
You seem excited at the thought of discovering an advanced alien civilisation. If we actually did discover very advanced aliens, would that be very exciting or very terrifying? It's difficult to say

Apparently, new data is not consistent with a swarm of comets; a new report is also due to be released by January. So far, scientists are baffled ... But who knows--maybe it's not extraterrestrials, but rather, some rare cosmic phenomena we haven't encountered before. Astronomers are delving into this and time will tell.

By the way, if I seem excited, it's because I am! I'm as excited as a SETI researcher--and I can't wait for what this lot find--at the prospect of finding 'people' from other planets! How can you not be? Think about how much humankind could learn from advanced aliens (if they are there) if we successfully communicate with them one day and then meet in the future. If they are dangerous, we may still learn from a distance--like safely observing lions in a safari park! :mrgreen:

If an alien civilisation has the technology and sheer power to construct such huge structures around stars, we had better hope they are much more peaceful than we are!
But then again, if they did have that kind of technology they would surely know that life existed on Earth and have obviously left us alone.

They may not even wish to communicate with us. (If SETI get not signals then they are either no longer there; or never were; or they are there but deem radiowave communication to be ineffective.)

Your concerns are similar to Stephen Hawking's. The scientist reckons a visit by aliens would be something akin to Columbus landing on American shores and confronting the Natives. As he said before:

'Such advanced aliens would perhaps become nomads, looking to conquer and colonise whatever planets they can reach.'

As I said before, Tabby's star's aliens would be a Type 2 Kardashev civilisation. Given the immensity of our universe, do you think a Type 3 could exist somewhere out there? (We are talking about something beyond Star Wars here!)

"Michio Kaku suggested that humans may attain Type I status in 100–200* years, Type II status in a few thousand years, and Type III status in 100,000 to a million years." (Wikipedia)

A million years sounds like a lot, but even in terms of life on our on planet, which may be 3000-4000 million years it is minuscule. If we assume that intelligent life is fairly plentiful in the universe (even just one such species in every few galaxies), the question may not be if a Type III civilisation exists, but instead how many. It appears that a Type III civilisation does not exist in our own galaxy but quasars and other phenomena we haven't even imagined yet would surely make such power possible.

I concur. 8-)

I'm a time traveller from the future. The aliens have already made contact. They kinda inadvertently show us how to build a time pod ...

I'd like that to be true very much, Enra! :-D

By the way, graphite (pure carbon) may have been found inside zircon crystals (the oldest rock fragments on Earth). If the dark specks inside the ancient crystals turn out to be carbon, then it suggests that life might have emerged 4.1 billion years ago instead of 3.8 as previously thought. If life emerged on Earth 270 million years earlier than previously thought (and 'only' 440 million years after our planet formed), then it could be quite abundant elsewhere in the universe if it emerged that fast and under extreme conditions! 8-)

'The faster life arises on Earth, the more varied and possibly extreme are the conditions in which it can do so elsewhere and be sustained.'

We've already made contact.
