Are Aliens More Lilliputian Than Green, Mega-Brained or Reptilian?

It turns out that Hollywood’s vision of big bad aliens could be all wrong. The aliens on the big screen could really be off the mark as a professor says they may be tiny invaders even microscopic or simply unrecognizable as a life form. Maybe they’re not even scary.

“In all the mathematical models, a species that started early in the history of the galaxy and had the will and resources to diffuse could by now have filled many parts of the galaxy with its artifacts or biological spores,” said Andrew Fraknoi, the emeritus chairman of the astronomy department at Foothill College and Fraknoi is on the board of the Search for Extraterrestrial Intelligence, known as the SETI Institute. He is a highly respected scientist. See our article Astronomer: “Light Is A Cosmic Time Machine”

“The intriguing possibility is they are, in fact, here, but we just don’t know it,” Andy continued and “they could be microscopic or unrecognizable as a life-form.”

“In other words,” Fraknoi said, “there has been ample time for a civilization to become advanced enough to send alien microbes or micro-artifacts around the galaxy, including to our solar system.”

In fact, the scientists point out that even rocks are vessels and very capable of transporting microbes from one planet to another and maybe further!

In an article appearing in the San Francisco Chronicle, they reported that:

(Andrew Fraknoi) has long speculated that members of a civilization billions of years old might by now have evolved into a mechanical-biological mix, like a robot with a brain, capable of living for thousands of years as they travel through space.

But it is also possible, he said, that advanced civilizations would have sent into space thousands of tiny canisters holding the germs of life programmed to incubate and grow when they encounter suitable conditions around a star.

Scientists theorize that space aliens may already be here, but we don’t recognize them

“In all the mathematical models, a species that started early in the history of the galaxy and had the will and resources to diffuse could by now have filled many parts of the galaxy with its artifacts or biological spores,” Fraknoi said.

The Chronicle says otherworldly speculation and discussion were prompted by “Oumuamua” Is The First “Confirmed” Interstellar Visitor To Enter The Solar System [VIDEO] and by the sighting last year of a comet named 2I/Borisov creating a surge of interest among scientists in space travel and alien civilizations.

Oumuamua first entered the solar system was confirmed after astronomers spotted what they suspected was an interstellar object in our Solar System. Now, they have just released a paper on 1I/2017 U1 (Oumuamua), the Hawaiian name that means “reach out or” and “first.”

The results of the study show that the object is a bizarre, elongated shape. It measures 10 times as long (400 meters) as it is wide, and spins on its axis once every 7.3 hours. The object, which scientists now believe is an asteroid, is dark and reddish in color. It also appears to be dense, meaning it is either rocky or has high metallic content.

“What we found was a rapidly rotating object, at least the size of a football field, that changed in brightness quite dramatically,” Karen Meech from University of Hawaii’s Institute for Astronomy (IfA), the study’s lead author, said in a statement. “This change in brightness hints that `Oumuamua could be more than 10 times longer than it is wide – something which has never been seen in our own Solar System.”

According to NASA:

When astronomers see something in the universe that at first glance seems like one-of-a-kind, it’s bound to stir up a lot of excitement and attention. Enter comet 2I/Borisov. This mysterious visitor from the depths of space is the first identified comet to arrive here from another star. We don’t know from where or when the comet started heading toward our Sun, but it won’t hang around for long. The Sun’s gravity is slightly deflecting its trajectory, but can’t capture it because of the shape of its orbit and high velocity of about 100,000 miles per hour.

What makes this all so fascinating according to the Chronicle is that:

ETI has been searching the skies for radio signals or some other sign of life beyond Earth for nearly four decades without a single peep.

Despite the failure, belief in the existence of extraterrestrial civilizations has only increased since Fermi’s time. That’s largely because powerful telescopes have recently detected numerous planets orbiting their stars at a habitable distance, known as the Goldilocks zone. Calculations indicate there are habitable planets around at least a quarter of the tens of billions of stars in the Milky Way Galaxy, possibly including the closest star, Proxima Centauri, 4.2 light-years from Earth.

Most astrophysicists believe life must have sprung up somewhere, some time, in the 13.5 billion years since the galaxy was formed. Given that our sun is 4.6 billion years old, Fraknoi said civilizations in other parts of the galaxy could have been using robotics, artificial intelligence and tapping the energy from their stars as many as 8 billion years before our solar system was created.

“We know there are rocks on Earth that came from Mars, so you could imagine that microbes could have potentially survived the journey,” says Avi Loeb, the chair of Harvard University’s astronomy department, “So it’s possible we are all Martians. If you can do it from Mars, you can potentially bring life from other planets in other galaxies.”

“Potentially, we could be part of an experiment where life was planted on Earth and someone is watching,” Loeb said. Adding that if that is the case that “for sure they are disappointed. That would be my assessment by reading the morning newspaper.”
