“We have no idea what is out there!”

"We have no idea what is out there!" 88

From life to dark matter to the billion-year-old technological civilizations: In 2019, several leading astrophysicists at NASA and Harvard and Columbia universities publicly announced their view that aliens are not science fiction: that advanced and ancient technological civilizations may exist, but are beyond our comprehension or ability to detect.

Already in NASA Contact Conference In 2002, which focused on serious speculation about advanced extraterrestrial life, one participant interrupted the keynote speech with the remark:

We have absolutely no idea what is out there!

In 2019, the Harvard astronomer, Avi Loeb wrote in his blog that aliens are not science fiction:

I don’t see extraterrestrials as more speculative than dark matter or extra dimensions. I think it’s the other way around.

Law of Great Numbers

Silvano P. Colombano from NASA’s Ames Research Center says:

Our life form and intelligence may just be a small first step in a continuous evolution that may well produce forms of intelligence far superior to ours that are no longer based on carbon machines.

The exoplanet discoveries made by the Kepler Mission (image above) identified the 10.4 billion-year-old planetary system (Kepler-10) and 11.2 billion-year-old (Kepler-444), providing a solid basis for Colombano’s speculation.

On average, all Milky Way stars have two planets in orbit. According to NASA, one fifth of these stars have a planet that can be conducive to life as we imagine it. This translates into 50 billion potentially habitable planets in the Milky Way alone – one of the two trillion galaxies in the observable universe.

Seth Shostak of the SETI Institute in Mountain View, California, said:

If you are going to say that there is no chance of finding life elsewhere, you must think that there is something truly miraculous on Earth. And this is a suspicious point of view, that we are miraculously better than all the other planets.

Given that our solar system is about 4.5 billion years old, there could be Earth-like planets, six billion years older than ours. Whereas further the technological development in our civilization began only about 10,000 years ago and saw the rise of science in the last 500 years only, Colombano watches that we may have difficulty predicting technological developments even in the next thousand years, and even less than six million times that amount.

Colombano says:

Our life form and intelligence may just be a small first step in continuous evolution, which may well produce forms of intelligence far superior to ours that are no longer based on carbon “machines.” After a mere 50 years of computer evolution, the human species is already talking about “super intelligence” and we are fast becoming symbiotic with the power of the computer.

In other words, technological civilizations may exist, but they are beyond our comprehension or ability to detect, says Colombano, who proposes that we may have missed signals when it comes to looking for UFOs.

While it is still reasonable and conservative to suppose that life probably originated in conditions similar to ours, the large time differences in potential evolution make the likelihood of finding technology similar to ours very small.

According to him, this is a great obstacle to a “quick” discovery of signs of an advanced Milky Way civilization.

Dark Sector Visitors?

Pointing out that Arthur C. Clarke suggested that any sufficiently advanced technology would be indistinguishable from magic, the Columbia University astrophysicist, Caleb Scharf, says in his article “Is Physical Law an Alien Intelligence?”(Is the Law of Physics an Alien Intelligence?):

If you’re meeting a bunch of paleolithic farmers with your iPhone and a pair of sneakers, it would certainly seem quite magical. But the contrast is only average: farmers would still recognize it as basically them and would soon take selfies. But what if life has advanced so far that it doesn’t seem simply magical but physical?

Scharf takes an even more exquisite leap, suggesting:

Dark matter may be hiding life. Perhaps this is where all technologically advanced life ends or where most lives have always been. What better way to escape the unpleasant whims of supernova and gamma-ray bursts than to take a form immune to electromagnetic radiation?

But, not resting on his speculative laurels, Scharf’s beautifully non-politically correct mind delves deeper and suggests:

Perhaps the behavior of the normal cosmic matter that we attribute to dark matter is caused by something quite different: a living state that manipulates light matter for its own purposes. Consider that at the moment we do not identify dark matter particles or create a compelling alternative to our laws of physics that would explain the behavior of galaxies and galaxy clusters. Would an explanation in terms of life be less plausible than a flaw in established laws?

Milky Way visitors?

Jonathan Carroll-Nellenback, an astronomer at the University of Rochester and his collaborators, said in a 2019 study which suggests that it would not be so long before a space civilization jumped from planet to planet across the galaxy, because star orbits can help distribute life, offering a new solution to the planet. Fermi’s paradox:

It is possible that the Milky Way is partially seated or intermittently so; maybe the explorers visited us in the past, but we don’t remember, and they disappeared.

The solar system may well be among other established systems; It just hasn’t been visited for millions of years.

Infinite Space Life

Dan Hooper, head of the Theoretical Astrophysics Group of Fermi National Accelerator Laboratory, wrote in “At the Edge of Time”:

If space is truly infinite, the implications are astonishing. Within an infinite extent of space, it would be hard to see any reason why there were no infinite number of galaxies, stars and planets, and even an infinite number of intelligent or conscious beings scattered throughout this unlimited volume. This is the question of infinity: it takes things that are very unlikely and makes them inevitable.

Why the universe does not fit into science

Why the universe does not fit into science 96

Science can be compared to an artist painting what he has never seen, or to a writer describing other people’s travels: objects that he has never seen, places where he has never been. Sometimes such scientific “arts” turn out to be beautiful and interesting, but most of them will forever remain only theories, because they are beyond human capabilities.

In fact, science has the right only to speculate: how our universe appeared, how old it is, how many stars and other objects it contains.

Universe model

Why the universe does not fit into science 97

How many stars are there in the sky?

With an unarmed eye, a person can see about nine thousand stars in the sky in one cloudless and moonless night. And armed with binoculars or a telescope, much more – up to several million. However, this is much less than their true number in the universe. Indeed, only in our one galaxy (the Milky Way) there are about 400 billion stars. The exact amount, of course, is not known to science. And the visible universe contains about 170 billion galaxies.

It is worth clarifying that scientists can see the universe 46 billion light years deep in all directions. And the visible (observable) universe includes the space accessible to our eyes from the moment of the Big Explosion. In other words, only this (accessible to human perception) space science refers to our universe. Science does not consider everything that follows.

It is believed that there are supposedly a ceptillion (10 to 24 degrees) stars in our universe. These are theoretical calculations based on the approximate size and age of the universe. The origin of the universe is explained by the Big Bang theory. This is why the universe is constantly expanding and the more time passes, the more complex the universe and its components become.

Why the universe does not fit into science 98

It is not entirely correct to consider and perceive this scientific theory “head-on”. Scientists always claim that that explosion was not exactly an explosion, and the point that exploded was not the only one. After all, it was everywhere, because space did not exist then. And in general – everything happened quite differently from what is described in the Big Bang theory, but all other descriptions of the origin of the universe are even more incredible and inaccurate.

Separate but interconnected

That which is beyond the reach of human perception is usually discarded by science, or recognized as non-existent. Recognizing one thing, science does not want to recognize the existence of the other, although everything in our world is interconnected and is not able to exist separately – by itself.

Each object of the universe is a part of it much more than an independent, separate object.

Any person, like any material object of our world, consists of components: organs, cells, molecules, atoms. And each of its constituent parts can represent the whole world. Separate, and at the same time connected with all the others.

However, science, as a rule, perceives all the components of the universe – people, animals, plants, objects, the Earth, the Sun, other planets and stars – as separate subjects, thereby limiting itself.

Why the universe does not fit into science 99

Even what is considered the visible universe, one of the atoms of which could be called our solar system, is not subject to the boundaries of human perception. But perhaps the atom is an exaggeration, and our solar system is not even an atom, but one of its elements!

How, being so far from the truth, can one reason about something with the degree of probability with which science tries to reason about the origin of the universe?

An unexplained wobble shifts the poles of Mars

An unexplained wobble shifts the poles of Mars 100

The red planet sways from side to side like a whirligig when it loses speed. The new study allowed scientists to notice that the poles of Mars deviate slightly from the axis of rotation of the planet. On average, they move 10 cm from the center with a period of 200 days.

Such changes are called the Chandler Oscillations  – after the American astronomer Seth Chandler, who discovered them in 1891. Previously, they were only seen on Earth. It is known that the displacement of the poles of rotation of our planet occurs with a period of 433 days, while the amplitude reaches 15 meters. There is no exact answer why this is happening. It is believed that the fluctuations are influenced by processes in the ocean and the Earth’s atmosphere.

Chandler’s wobbles on Mars are equally perplexing. The authors of the study discovered them by comparing data from 18 years of studying the planet. The information was obtained thanks to three spacecraft that orbit the Red Planet: Mars Odyssey, Mars Reconnaissance Orbiter and Mars Global Surveyor. 

Since Mars has no oceans, it is likely that the Red Planet’s wobbly rotation is due to changes in atmospheric pressure. This is the first explanation that researchers have shared. In the future, there should be new details about the fluctuations that have so interested the scientific community.

Possible “portals” to distant regions of the Universe found in space

Possible "portals" to distant regions of the Universe found in space 101

Scientists have found in space possible “portals” to distant regions of the universe. They could be some supermassive black holes in the center of galaxies. This is reported by the Monthly Notices of the Royal Society magazine. In theory, a spaceship can pass through such portals.

Russian scientists have found that black holes in very bright galaxies may be the entrances to these “portals” or “wormholes”. In theory, a spaceship can pass through such portals. However, they are surrounded by intense radiation, which negates the crew’s chances of survival.

The similarity between a wormhole and a black hole is that they have extremely strong gravity. However, as scientists believe, the body cannot get out of the black hole, falling beyond the event horizon, while the “wormhole” must have an exit somewhere else in space.

So, experts say, the collision of two bodies inside a wormhole in images from space would look like an explosion. That is, the active galactic nucleus (AGN), which seemed to be such earlier, may in fact be the entrance to the “portal”.

Russian physicist Mikhail Piotrovich emphasizes that scientists still know little about the internal structure of the “wormhole.” Moreover, they are not even sure that such a phenomenon exists at all. In addition, the closest object similar to it is 13 million light-years away, so humans are unlikely to be able to reach it in the foreseeable future.
