Instead of finding alien life, should we be hiding from it?

A recent study suggests a method for hiding from aliens. This study, published in the Monthly Notices of the Royal Astronomical Society, comes at a time when most papers and study are related to how to find alien life.

A great deal of our quest for Earth-like planets depends on transiting planets. Transiting planets travel in front of their host star in a manner in which the transit can be seen from our viewpoint. The travel of the planet in front of the host star makes the light from that star diminish or glimmer, and we can utilize that to determine a wide range of information about far off planets — including how sustainable they might be for life.

A few scientists have proposed that we ought to hope that Earth is a transiting planet from the viewpoint of another planet that contains intelligent life. At the end of the day, our best endeavor for discovering alien life may be trusting that aliens are utilizing similar techniques of planetary detection that we are, and that the movement of Earth in front of the sun is visible with their telescopes.

Graduate student Alex Teachey and Professor David Kipping, both from Columbia University in the City of New York, attempted to figure out how much laser light would be required to cover the diminishing or glimmering light brought about by the transit of Earth.

As indicated by their calculations, it would take about 10 constant hours of shining a 30 MW laser once every year to shield the transit signal in discernible light. Reproducing each wavelength of light released by the sun would require around 250 MW of power.

Teachey said in a statement that “Alternatively, we could cloak only the atmospheric signatures associated with biological activity, such as oxygen, which is achievable with a peak laser power of just 160 kW per transit. To another civilization, this should make the Earth appear as if life never took hold on our world.”

There’s still a major, interdisciplinary deliberation about whether we should try to contact alien life from other planets. This study will become one of many that detail whether or not we should be hiding from alien life, instead of if we should find it and try to communicate with them.

All aliens are dead

Recent research proposes that any life on habitable planets would likely be wiped out very quickly.

Analysts from The Australian National University say, in the journal Astrobiology, existence on a developing planet would most-likely “die out due to runaway heating or cooling.”

Aditya Chopra from The Australian National University Research School of Earth Sciences and lead author on the paper said, ”The universe is probably filled with habitable planets, so many scientists think it should be teeming with aliens.”

The major explanation, says Chopra, is the absence of solidity.

“Most early planetary environments are unstable,” Chopra said. “To produce a habitable planet, life forms need to regulate greenhouse gases such as water and carbon dioxide to keep surface temperatures stable.”

Two cases  of this are Venus and Mars; these planets could have been habitable at one point, but while Venus became a “hothouse,” Mars became a relative “icebox.”

The paper’s co-author, Charley Lineweaver, from The Australian National University Planetary Science Institute, states that any basic existence on Mars or Venus could have failed to help stabilize the environment.

The study additionally clarifies Fermi’s Paradox, which expresses that in spite of the high chances of habitable planets, we have yet to locate any indication of extraterrestrial life.

Scientists say that a conceivable answer to Fermi’s paradox is near universal early extinction, which they have named the Gaian Bottleneck.

In exploration planning to see how life may develop, the researchers acknowledged that new life would regularly cease to exist because of runaway warming or cooling on their developing planets.

Around four billion years ago, Earth, Venus and Mars might have all been habitable. However, a billion years or so after formation, Venus turned into a hothouse and Mars froze into an icebox.

Early microbial life on Venus and Mars, if there was any, neglected to balance out the quickly evolving environment, said co-author Associate Professor Charley Lineweaver from the Australian National University Planetary Science Institute.

Rough, wet planets, with the ingredients and vitality sources required for life appear to be omnipresent, on the other hand, as physicist Enrico Fermi called attention to in 1950, no indications of surviving extraterrestrial life have been found.

Aliens are coming

Before you read the article, go watch the video here.

A mysterious blue light was seen streaking across the Southern California sky at night on November 7. The strange object that sparked fears of nuclear war, an incoming meteor and an alien invasion, was in fact an unarmed missile test-fired by a Navy submarine.

Initially, the strange object appeared as an orange light moving very rapidly. In a flash, the orange light altered into a giant blue light, while the object was never seen in full.

A Navy spokesman told the San Diego Union-Tribune that “The Navy Strategic Systems Programs conducted the scheduled Trident missile test flight at sea from the Kentucky, an Ohio-class ballistic missile submarine, in the Pacific Test Range off the coast of Southern California”. The projectile was part of an ongoing chain of tests to ensure the consistency of the weaponry and the assurance in their competences.

Ryan Perry, a spokesperson with the Navy’s 3rd Fleet, stated that the missile — a Trident II (D5) that could be seen as far away as Arizona and Nevada — was unarmed. He said information about such exercises is confidential before the launch begins.

The test was performed in the Pacific Test Range, the Associated Press reported, a vast area northwest of Los Angeles that the Navy uses to test-fire Tomahawk and Standard cruise missiles.

The absence of information about the rocketing light psyched up social media and led many people to turn their cellphones in the direction of the sky. As well as posting images and video of the object online, witnesses bombarded local law enforcement agencies with phone calls, according to the Associated Press.

The Los Angeles International Airport mentioned the testing in a statement released earlier last week, according to the AP.

These tests will create traffic route limitations briefly while nighttime flights into and out of Los Angeles International Airport will have to temporarily deviate from passing over the Pacific Ocean west of the LAX airport for the upcoming week because the U.S. military is using airspace there, Reuters reports.

The military test is set to continue until November 12, according to the AP.

 

Alien space ship? Probably not.

The internet exploded this week when scientists from NASA announced that they had spotted a strange star that appeared, without a better comparison, like the Death Star from Star Wars.

Scientists had been observing KIC 8462852 (or the WTF star) when they noticed some unusual behavior around the star. The internet, naturally, has been quick to shout, “ALIENS!” This is because the star was observed with strange dips in brightness. One paper theorized that these dips in brightness may be caused by comets being forced towards the sun by the heavy gravity of a large passing planet or star.

Of course, there’s also the less likely theory that the WTF star is encased in a giant alien structure which absorbs energy from it.. Some believe that the giant structure is lined with solar panels, and that aliens are harnessing the power of this star to power their own super-alien technology.

Scientists have stressed that the public shouldn’t get their hopes up. Just as earlier this year, when there was thought to be an alien spaceship near our own sun, this is likely to be just as disappointing. If you don’t recall, there was a strange spotting in a sun flare which was thought (by the internet, of course) to be a giant alien mothership stopping by the sun to absorb energy from it.

Scientists from SETI have begun using one of their own telescopes to try to detect any artificial radio waves emanating from the star. NASA’s Kepler telescope discovered the strange star, along with over a thousand exoplanets, and thousands of other objects waiting to be identified.

According to the website I Fucking Love Science, “This study is only the first of on a potentially long series of observations by SETI based on Kepler’s data. The planet hunter’s data implies the possibility of billions of habitable rocky planets in the Milky Way – billions of possible leads for SETI astronomers to chase.”

So are there aliens out there? Scientists think so. As vast as our universe is, there has to be other life out there, right? In April, Ellen Stofan, one of NASA’s high-ranking scientists claimed that “we’re on the right road” to finding alien life. She suspects within the next 20-30 years, we will have definitive evidence of alien life.

Don’t get your hopes up too high for this unlikely alien theory, because you’ll likely be disappointed. However, if we can find water on mars, what can’t we do?

Aliens aren’t little green men?

For the longest time, a popular depiction of alien life forms has been that of a little green man. However, cosmologist, Fergus Simpson, has just released a paper, “The Nature of Inhabited Planets and Their Inhabitants,” attempting to disprove that common theory.

Simpson’s theory is based on the law of the conservation of energy. He concludes that larger species need more energy to survive, which is why these aliens can’t live amongst human beings on Earth. Simpson explains that “throughout the animal kingdom, species which are physically larger invariably possess a lower population density, possibly due to their enhanced energy demands. As a result, we should expect humans to be physically smaller than most other advanced species.”

Simpson theorizes that aliens should weigh around 650 pounds, based on his mathematical calculations — a stark contrast to the image that Americans hold dear in their hearts.

While the internet is blowing up talking about Simpson’s theory, many scientists are skeptical. Seth Shostak, a researcher for the SETI Institute, announced that he himself was conducting similar research and insists that while the theory is “interesting,” there’s “no concrete data to work with.”

Another part of Ferguson’s theory states that these massive aliens may be more intelligent than human beings due to their large mass. However, Shostak disagreed with that idea. He claims that human beings have particular features that make them the most intelligent life forms on Earth, such as their ability to move upright and use their thumbs. To back up his argument, Shostak went on the record saying, “Polar bears are large, but do not write great literature and build radio towers, and a lot of that is probably because they are walking around on all fours.”

Shostak isn’t Simpson’s only critic. Many people claim that while reasonable, Simpson’s theory fails to factor in gravity, which is a huge part of bodily mass. Because Earth’s gravitational pull is so strong, it makes sense for organisms to be larger. However, other planets’ gravitational pulls are proven to be significantly weaker. While this argument doesn’t note that these large life forms could live in a different galaxy, these critics still have a valid point.

If intelligent life does exist in this galaxy or in a nearby one and has the ability to make contact with the inhabitants of Earth, we should all pray that Simpson’s research is wrong and that these aliens are indeed the tiny green men that we have always imagined.

Go back to sleep, sheeple

Sometimes I really enjoy reading about government conspiracies such as MK Ultra or Area 51 or the entire plot of “Conspiracy Theory.” The government is sketchy in so many ways that they’re an easy target for the plot of a cheesy fanfic. The problem is that people believe their own fanfics and post them on the internet where anyone can read them. People take them seriously and before you know it, we have a full scale government conspiracy theory. Continue reading Go back to sleep, sheeple

Sexy aliens? Science says probably not

We humans (or at least, the geekier specimens among us) seem obsessed with human-on-alien action. From the countless conquests of Captain Kirk to the untamed Na’vi beauty Neytiri, science fiction is replete with tales of uninhibited extraterrestrials that know just how to get our motors running.

But is it really likely that even if we’re not alone in the universe, our galactic neighbors will want to pay conjugal visits? Probably not. Continue reading Sexy aliens? Science says probably not

Mother Mars

When we envision Martians visiting Earth, the image is usually one of little green men stepping out of a flying saucer and greeting the astonished humans. We don’t usually imagine bacteria from Mars arriving on Earth via meteorite and then over millions of years evolving into humans. But according to Time, that may be exactly what happened all those years ago. Continue reading Mother Mars
