OK, so a couple of physicists walk into a bar. Just kidding. They’re not at a bar. They’re at a school. Scientists in training. I’m sure this story seems strange to you, but to me, it was just– you know, this was just like another day in the physics world. David Kestenbaum used to live in physics world. These days he lives in our world. But at the time of the story, he was getting a PhD in high-energy particle physics at, um– there’s no way to avoid the name-droppy-ness of what I’m about to say– at Harvard University.

Juggling all the factors impacting the emergence of extraterrestrial civilizations is no easy task, which is why the Drake equation has become such a handy tool. But are there assumptions locked inside it that need examination? Robert Zubrin thinks so, and in the essay that follows, he explains why, with a particular nod to the possibility that life can move among the stars.

Although he is well known for his work at The Mars Society and authorship of The Case for Mars , Zubrin became a factor in my work when I discovered his book Entering Space: Creating a Spacefaring Civilization back in , which led me to his scientific papers, including key work on the Bussard ramjet concept and magsail braking.

One can easily substitute boyfriends in here but as I am mostly a heterosexual male I will focus on the search for a girlfriend. Perhaps his problem is that he’s a fussy bastard, then? He specifically mentioned “attractive to him”. Maybe he just doesn’t want to lower his standards too much. It is of course purely subjective, I know. Also, as a 31 year old man he does seem to be skewing his age preference “young”.

He could probably improve his odds by increasing the upper bound without fear of the dreaded “cougars”. That he even uses that term does not make me think well of him. Perhaps that is my problem here? I suspect that if I were a university-educated woman who lived in London and whose physical attractiveness was in the top fifth percentile, I wouldn’t be looking for love among graduate students in the Warwick University Economics Department.

## The Drake Equation

Paul Sutter has a way with words. In a Space. For the precocious hunter of off-Earth life, the Drake equation is the ever-ready, go-to toolkit for estimating just how not lonely humans are in the Milky Way galaxy.

The Drake equation was developed in by American astronomer Frank Drake, Drake’s equation then multiplies the number of planets in the habitable zones of stars by Fossil tardigrades have bee found dating back million years.

Kathleen Lohnes was an editorial intern at Encyclopaedia Britannica in and On a clear night, staring up at the stars induces a sense of simultaneous wonder and insignificance. Humanity time and time again finds itself lost amid the vastness of a universe that we are still struggling to understand. There are many questions we ask ourselves when looking toward the heavens, but one of them always feels just outside of our grasp: Across all the billions of light-years of starry sky above us, could we possibly be the only life?

Scientists have explored this question for years. In physicist Frank Drake developed a mathematical equation to help solve it:. The equation aimed to find the number N of intelligent civilizations within the boundaries held by the subsequent factors—in our case, the Milky Way Galaxy. To break these numbers down further, scientists use the Kardashev scale, which splits intelligent life into three categories. Type I civilizations are able to use all the energy available on their home planet we are approaching this; most scientists agree that we are currently at a 0.

Type II civilizations can control and channel all the energy of their host star, and Type III civilizations have access to power equivalent to that of their host galaxy. Even before the Drake equation and the Kardashev scale, many scientists were convinced that there must be a plethora of intelligent civilizations sprinkled across the galaxy. The story goes that in Enrico Fermi and his colleagues were discussing the existence of alien life over lunch.

One of the longest-running projects in the Search for Extraterrestrial Intelligence SETI came to an end, at least temporarily, last week. The SETI home project started in as a distributed computing effort, allowing participants to use spare time on their home computers to process batches of data collected by radio telescopes.

It immediately became popular by people who enjoyed the opportunity to take part in SETI with little more than an Internet-connected computer running a colorful screensaver. More than two decades of data analysis, of course, turned up no evidence of any signals from civilizations other than our own, just like every other SETI effort to date. At the same time, though, astronomers have found a growing number of exoplanets with sizes and orbits similar to the Earth, or otherwise orbit stars in zones that would allow liquid water on their surfaces.

Biologists, meanwhile, have shown just how hardy life is on Earth, existing in conditions once thought uninhabitable, raising the prospects for life elsewhere in our solar system and beyond. For SETI, Roush says there are three such premises: that astrophysics and biology show that there should be plenty of extraterrestrial civilizations, that those civilizations should have had time to expand through the galaxy, and that there are no signals or other evidence of such civilizations.

The emphasis, though, is on seemingly sound premises.

Some time ago, I wrote an article on the optimal way to select a mate, assuming you know how many eligible partners exist, and that once you’ve dated someone, you can’t go back and date them again sorry, Drew Barrymore and that dude from the Apple commercials. This is less romantically known as the secretary problem. Let me briefly recall the problem and its solution: suppose you have n candidates, from which you want to pick the best one.

This applies to a variety of situations, from hiring a secretary to finding a girlfriend to apartment hunting. The major problem with this model is that in many situations, the value of n is unknown. There are ways to circumvent this problem, which I will not discuss here. Instead, in the context of finding a mate, I offer the following method to calculate the number of partners you could reasonably expect to find in your area.

This method recently gained some attention when Peter Backus, a Ph. The basic technique involves modifying the Drake Equation , an equation used to estimate the number of potential extraterrestrial civilizations in our galaxy. For those who have never been introduced to this equation, it asserts the following:. Given estimates for all of these parameters, one could then estimate the number of civilizations in our galaxy.

His quirky study uses a famous maths formula called The Drake Equation, which was first used to estimate the existence of extra-terrestrial life. The results don’t look promising for British singles. The mind-numbing equation takes into account the number of women aged 24 to 34, living in his home city of London, and who are single, meaning his chances of meeting his dream woman on a night out are slim.

The economics expert said: “There are 26 women in London with whom I might have a wonderful relationship. Mr Backus simply replaced the original equation with his own criteria for a dream date, which included the percentage of women likely to find him attractive, and the number of girls aged in London. He said: “The research may sound depressing to people looking for love, but the good news for singles is, it’s probably not your fault!

## Mistakes in the Drake Equation

This question has haunted alien hunters ever since the Nobel-winning physicist Enrico Fermi posed it to some colleagues over lunch 70 years ago. There are billions of sun-like stars in our galaxy, and we now know that most of them host planets. Researchers working on the search for extraterrestrial intelligence, or SETI , have proposed a number of solutions to the Fermi paradox over the years. But the most persuasive answer is also the most obvious: Perhaps intelligent life is just far more rare than we thought.

How rare? Many scientists have attempted to answer this notoriously tricky question.

love in the British capital using the same “Drake” equation scientists his paper on the equations of finding love, Backus has started dating.

The Drake Equation is a formula for the number of developed civilisations in our galaxy, the Milky Way. This number is determined by seven factors. Some are known with good accuracy but the values of most are quite uncertain. It is a simple equation comprising seven terms multiplied together see illustration. There are no exponentials, no power laws and no logarithms; the equation is linear in each of its factors.

All terms are equally important, and the overall uncertainty is dominated by the most uncertain terms. This meeting was to investigate the possibility of detecting intelligent life in the Milky Way. The equation had terms representing the key quantities that would need to be determined in order to estimate the likelihood of life on other planets.

It was intended as an instrument to facilitate discussion, but has proven to be very durable. It is a valuable teaching aid and is found in many university textbooks on astronomy. Each of the seven terms in the equation was estimated at the conference. The first term is the rate at which new stars are formed in the galaxy.

It has a value of about 20 per year.
