Aliens are a lot bigger than us, says scientist

Published

Technically incorrect: Cosmologist Fergus Simpson believes that the most intelligent aliens out there will likely weigh 650 pounds. Yes, little green people could be very, very big.

Fergus Simpson, a scientist at the Institute of Cosmos Sciences at the University of Barcelona, believes that aliens are large. As CNET explains, he used a mathematical model that assumes organisms on other planets obey the same laws of conservation of energy that are seen on Earth.

“Throughout the animal kingdom, species which are physically larger invariably possess a lower population density, possibly due to their enhanced energy demands,” Simpson states.

He says that “most inhabited planets are likely to be closer in size to Mars than the Earth,” which leads him to surmise that, “since population density is widely observed to decline with increasing body mass, we conclude that most intelligent species are expected to exceed 300kg.”

So he’s speculating that most intelligent extraterrestrials are an impressive 650 pounds.

SETI Institute’s senior astronomer Seth Shostak has also suggested that intelligent extraterrestrials are likely larger than humans. But he acknowledges the speculative nature of these types of studies. “It’s interesting, but there’s really no concrete data to work with,” he says.

Duncan Forgan, an astrobiologist at the University of St Andrews School of Physics and Astronomy, thinks Simpson’s “average size calculation is reasonable.” But he criticizes the paper for failing to “address the correlation between body mass and the planet’s surface gravity.”

Newsweek points out that “We only have our planet and its inhabitants to serve as a model for what life looks like. This paper, like others, assumes that Earth is a ‘typical’ or average planet, and uses information from here to make assumptions about the unknown. But it’s impossible to know if that’s appropriate to do, from a scientific point of view.”

Simpson’s paper is published at arXiv.org.

Former US Air Force fighter pilot: UFOs use Star Trek-style warp drive

Published

By

A former US Air Force fighter pilot asserts that he has deciphered
the method behind the extraordinary maneuvers of UFOs, reports dailystar.co.uk.

Over
the past two decades, numerous military encounters with these enigmatic
crafts have been reported, prompting a significant investigation by the
Pentagon.

One of the most renowned sightings occurred during the
USS Nimitz encounter, where fighter pilots witnessed a UFO descending
from 28,000 feet to just above sea level in less than a second.

This
astonishing movement would imply that the craft reached a staggering
speed of 19,000 miles per hour, a velocity that would be fatal to any
human pilot.

According
to Chris Lehto, a former USAF pilot, the craft exhibits two key
characteristics: it moves without inertia, essentially lacking weight,
and it accelerates at an incredibly rapid pace without affecting its
surroundings.

Chris
believes that the explanation lies within a technology that seems
straight out of science fiction. He proposes that the answer to the UFO
enigma lies in the Alcubierre Drive, a theoretical interstellar engine
conceptualized by Mexican physicist Miguel Alcubierre in 1994.

The
Alcubierre Drive employs a form of “space warp” technology, reminiscent
of what has been depicted in episodes of Star Trek. By bending space, a
craft inside a “warp bubble” could potentially travel at or even
surpass the speed of light without violating the known laws of physics.

While
the Alcubierre Drive remains a hypothetical concept with challenges to
overcome, Chris notes that the required energy is no longer believed to
be unattainably large.

Patents
filed with the US patent office outline the potential workings of the
drive, as well as another groundbreaking technology theorized by
American aerospace engineer Salvatore Pais.

Pais suggests that
high-powered rotating magnets could theoretically eliminate an object’s
inertia, and he has filed a patent for a starship based on this
principle.

However, Chris maintains skepticism regarding Pais’
theory. He explains that while Pais’s patent applications for the US
Navy attracted attention for their potential energy-related
applications, doubts have been raised about their feasibility. There is
speculation that they may be scams, pseudoscience, or disinformation
intended to mislead adversaries of the United States.

Alternatively,
rival theories propose that the “Tic Tac” UFO is a classified Pentagon
project testing similar advanced technologies discussed by Chris.

A Mysterious Earth-Like Planet Has Just Appeared in Our Solar System, Scientists Say

Published

By


Scientists say they have found evidence of a new Earth-like
planet that has suddenly appeared in our Solar System and is orbiting
the Sun.

Physicists, including those from the National Astronomical Observatory
of Japan, said the planet is likely to be the mysterious ‘Planet Nine’
that was hypothesised to exist in the far outer edges of the Solar
System.

Several studies in the past have suggested there is likely an
undiscovered planet beyond the Kuiper Belt – a stellar disk of materials
such as asteroids, space rocks, comets around the Sun in the outer
Solar System past the orbit of Neptune.

Independent.co.uk reports: In the new research, published recently in The Astronomical Journal, scientists
found that some of the objects in the Kuiper Belt behave in a way
indicative of the presence of a small planet among them.

One such object, they said, is about 500 astronomical units (AU) from
the Sun, where 1 AU is the distance between the Sun and the Earth.

In comparison Neptune is at a distance of 30 AUs from the Sun.

Some of these were also found to have “odd” orbits suggesting they
are being pull by the gravity of a cosmic entity larger than those that
typically influence such objects.

Computer simulations run by the scientists indicate that the most
likely explanation for the observations was another hidden planet in the
Kuiper Belt.

“We predict the existence of an Earth-like planet,” researchers wrote in the study.

“It is plausible that a primordial planetary body could survive in
the distant Kuiper Belt as a Kuiper Belt planet (KBP), as many such
bodies existed in the early solar system,” they added.

If such a planet exists, researchers say it would have a mass about
1.5 to 3 times that of Earth with an inclination of about 30 degrees.

They say the theorised planet’s orbit would likely place it between 250 and 500 AU from the Sun.

Researchers say the discovery of such a planet close to the Kuiper
Belt can unravel new constraints on planet formation and evolution.

“In conclusion, the results of the KBP scenario support the existence
of a yet-undiscovered planet in the far outer solar system,” scientists
noted.
