Harvard astrophysicist Avi Loeb is not your typical astronomer. For many years, he’s been scouring the universe for the abnormal and the unknown. “Brushing anomalies under the carpet of traditional thinking,” as he puts it, is anathema for him.
“One way to learn more,” he told me, “is to pay attention to the anomalies, because they may lead us to something that we’ve never thought about … Maybe they will open up our eyes to extra dimensions … or new physics.”
In 2021, Loeb founded the Harvard-based Galileo Project to speed up the scientific search for evidence of extraterrestrial objects. Since then, Loeb has been supervising the construction of three state-of-the-art observatories in the United States: one in Massachusetts, one in Pennsylvania and one in Nevada. They make use of machine learning models to identify unexplained anomalies and use triangulation to infer the distance of objects from Earth.
“Instead of waiting for the U.S. government to release its data, we just look up and ask, are there any objects up there that are not human-made? And of course, anything that is human-made is boring, as far as I’m concerned,” he said.
Did his observatories find evidence of objects that might be extraterrestrial? Perhaps. They detected objects that, as he said, “arrive in our backyard from outside the solar system.” Such interstellar objects were purely theoretical before 2017, when the first one was discovered. Since then, two more have been found. This, he told me, is the new frontier in astronomy.
But are these interstellar objects of natural origin? Many astronomers believe they are, but Loeb is not so sure. Take, for example, Oumuamua, the first recognized interstellar object ever discovered: Its core features are undisputedly abnormal. Oumuamua moved very quickly without a recognizable method of propulsion. And as it left the solar system, it accelerated to a degree that could not be explained by gravity alone.
Loeb has been arguing that Oumuamua might be an artificial light sail propelled by solar radiation pressure and built by ancient civilizations that exist or existed beyond our solar system.
“Most of the stars formed billions of years before the sun. The sun formed only 4.6 billion years ago … There was plenty of time for Voyager-like probes to arrive in the solar system. And so we are searching for any technological artifacts, objects very different from traditional SETI,” he said.
SETI stands for “Search for Extraterrestrial Intelligence” and refers to a project dedicated to detecting advanced extraterrestrial civilizations.
Here are some of the many other topics we discussed in our wide-ranging interview:
-What is the origin of hypervelocity stars that race through the universe at a significant fraction of the speed of light? -Are there other dimensions beyond our own? -How would the discovery of extraterrestrial life impact religious views? -Is AI a form of alien intelligence?
