The feats achieved by the Ancient Egyptians have long flummoxed even the most renowned experts. For example, how on earth did they build the Great Pyramid of Giza? It’s taken centuries for scientists and archaeologists to come up with an answer, and even that’s not set in stone. But now, researchers believe they’ve finally worked out how the Great Sphinx was made more than 4,500 years ago. Sure, there’s a pretty broad consensus about how the face of the giant limestone statue was created – it was most likely hand-carved by stone masons. But the imposing, multi-layered body had continued to evade explanation. However, researchers at New York University, have finally concluded that the body came about. And it wasn’t all thanks to the masonry skills of local workers. They believe that the shape was sculpted by Mother Nature herself, in the form wind. “Our findings offer a possible ‘origin story’ for how Sphinx-like formations can come about from erosion,” Leif Ristroph, senior author of the study, said in a statement. “Our laboratory experiments showed that surprisingly Sphinx-like shapes can, in fact, come from materials being eroded by fast flows.” For their study, the team took harder rock encased in mounds of soft clay to mimic the terrain along the Nile River in northeastern Egypt. They then washed over these formations with a fast-flowing stream of water to replicate the wind and, in the end, the clay assumed a Sphinx-like shape. The resulting form consisted of a lion’s “head,” “neck,” “paws” laid out in front and an arched “back". “There are, in fact, yardangs (rock features formed by air erosion) in existence today that look like seated or lying animals, lending support to our conclusions,” Ristroph pointed out. Still, we’re sure Ristroph would be the first to admit that he and his colleagues weren’t the first to come up with the aeolian erosion theory. In 1981, geologist Farouk El-Baz suggested that the iconic Sphinx was originally a flat-topped shape that was worn down by wind over time. Furthermore, El-Baz believed that the builders of Ancient Egypt would have known of these natural processes, and so carefully selected the shapes of their most iconic structures to withstand them. "Today, the pyramids of Giza exist in perfect harmony with their windy environment," the scientist said back in 2001. "Had the ancients built their monuments in the shape of a cube, a rectangle, or even a stadium, they would have been erased by the ravages of wind erosion long ago." Nevertheless, the New York University team were the first to show exactly how this phenomenon could have occurred, and their findings have broader implications. "The work may also be useful to geologists as it reveals factors that affect rock formations—namely, that they are not homogeneous or uniform in composition,” Ristroph said. "The unexpected shapes come from how the flows are diverted around the harder or less-erodible parts." Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

A new technique is a dramatic breakthrough in the search for alien life, astronomers say. Researchers at the Breakthrough Listen project based at the University of California, Berkeley say they have developed a new way to be sure that any potential signal is really coming from space – and not from something more boring. Astronomers spend vast amounts of time looking for radio signals that might have come from alien civilisations as part of work on the search for extraterrestrial intelligence, or SETI. But they have in the past been fooled by very human technology, such as cellphones, microwaves and car engines, that can produce a blast of radio signals that look as if they have come from distant worlds. One way to check whether signals are really alien is to point the telescope elsewhere and then repeatedly return to the same spot, with the hope of seeing the signal again and ensuring that it is not a false alarm. But that is not foolproof – and only works if the signal sticks around. Some of the most promising radio signals might only be detectable once. The so-called “Wow!” signal, for instance – a radio signal detected in 1977 that was so shocking the astronomer who found it wrote the exclamation on a printout – has not been detected since, and astronomers still do not know whether it was an alien message or just a mistake. Now scientists have devised a new test that can be used to see whether a signal has really passed through interstellar space, which should help show that it is not from elsewhere on Earth. It works by looking for “scintillation” – the changes in amplitude of a signal as it is affected by the cold plasma of space. “The first ET detection may very well be a one-off, where we only see one signal. And if a signal doesn’t repeat, there’s not a lot that we can say about that. And obviously, the most likely explanation for it is radio frequency interference, as is the most likely explanation for the Wow! signal,” said Andrew Siemion, principal investigator for Breakthrough Listen and director of the Berkeley SETI Research Center, which operates the world’s longest running SETI program. “Having this new technique and the instrumentation capable of recording data at sufficient fidelity such that you could see the effect of the interstellar medium, or ISM, is incredibly powerful.” Dr Siemion called the breakthrough “one of the biggest advances in radio SETI in a long time” and said that it would be the first time researchers would be able to differentiate a real signal from a false alarm, even if it was only detected once. The technique can only be used for signals that have travelled 10,000 light years or more to Earth, researchers note. If it was closer to us, the scintillation effect cannot be seen because they are not travelling through enough of the interstellar medium, or ISM. The research is described in a new paper, ‘On Detecting Interstellar Scintillation in Narrowband Radio SETI’, published in The Astrophysical Journal.
