Ever heard of the rule that men should date women who are half their age plus seven? Some celebrities – think Leonardo Di Caprio – take this to extremes with a roster of something models regularly appearing on their arm, but do you know where the saying comes from? But does it stand up to scrutiny, or is it just a baseless rule perpetuated by men who want to justify dating younger, and less mature, women? We asked three relationship experts to weigh in on the rule – and their responses were surprising. Historically, a woman was to choose a man the same age, or five to 15 years older. Mid-century, the reason for the elevated age gap would’ve been economic. Women had little ability to earn income. Their husband was their access to social standing and economic stability. Obviously, an older man had more time to achieve a greater number of personal and financial goals.

About 75 years ago, Williard F. Libby, a Professor of Chemistry at the University of Chicago, predicted that a radioactive isotope of carbon, known as carbon, would be found to occur in nature. Since carbon is fundamental to life, occurring along with hydrogen in all organic compounds, the detection of such an isotope might form the basis for a method to establish the age of ancient materials.

Working with several collaboraters, Libby established the natural occurrence of radiocarbon by detecting its radioactivity in methane from the Baltimore sewer. In contrast, methane made from petroleum products had no measurable radioactivity. Carbon is produced in the upper atmosphere when cosmic rays bombard nitrogen atoms. The ensuing atomic interactions create a steady supply of c14 that rapidly diffuses throughout the atmosphere.

Plants take up c14 along with other carbon isotopes during photosynthesis in the proportions that occur in the atmosphere; animals acquire c14 by eating the plants or other animals. During the lifetime of an organism, the amount of c14 in the tissues remains at an equilibrium since the loss through radioactive decay is balanced by the gain through uptake via photosynthesis or consumption of organically fixed carbon.

However, when the organism dies, the amount of c14 declines such that the longer the time since death the lower the levels of c14 in organic tissue. This is the clock that permits levels of c14 in organic archaeological, geological, and paleontological samples to be converted into an estimate of time. The measurement of the rate of radioactive decay is known as its half-life, the time it takes for half of a sample to decay. This means that half of the c14 has decayed by the time an organism has been dead for years, and half of the remainder has decayed by 11, years after death, etc.

You may be familiar with the “divide their age by two and add seven” equation for figuring out if the person you’re into is too old for you to date. This test supposedly calculates the youngest age that it is appropriate for a person to have a romantic relationship with. So if you’re 23 and your crush is 38, the numbers say it’s a no-go.

Wait until you’re 26, however, and you can start hooking up with year-olds. It’s a silly “rule,” and it doesn’t appear to have any science behind it.

At 26, the range of non-creepy partners is 18 years ( to year-olds). At 50, it is 54 years (32 to 86 years old). At age 14, you can only date people your own.

Two things: the somewhat random-looking picture above is from The Moon Is Blue, a film that’s the first known reference to the ‘dating rule’ discussed here. Secondly, I don’t make any judgement about the validity of the ‘dating rule’ – you might find it a useful rule of thumb or a ludicrous restriction; I find it a nice thing to do some algebra on. There is a so-called rule about dating: the youngest age you are supposed to date is half your age plus seven.

Why would we want to do this? Well, it means we can work out some other implications of the rule. For instance, you might want to know what the oldest age you could reasonably date would be. The rule doesn’t say anything about that, but it does also apply to the other person. How do we work that out?

Planet Earth doesn’t have a birth certificate to record its formation, which means scientists spent hundreds of years struggling to determine the age of the planet. So, just how old is Earth? By dating the rocks in Earth’s ever-changing crust, as well as the rocks in Earth’s neighbors, such as the moon and visiting meteorites, scientists have calculated that Earth is 4. Related: How Big is Earth? Scientists have made several attempts to date the planet over the past years.

They’ve attempted to predict the age based on changing sea levels, the time it took for Earth or the sun to cool to present temperatures, and the salinity of the ocean. As the dating technology progressed, these methods proved unreliable; for instance, the rise and fall of the ocean was shown to be an ever-changing process rather than a gradually declining one. And in another effort to calculate the age of the planet, scientists turned to the rocks that cover its surface.

Scientists also must battle an issue called the Great Unconformity, which is where sedimentary layers of rock appear to be missing at the Grand Canyon, for example, there’s 1.
