Msuch as David Sperkels profession The focus is on studying the universe. An astrophysicist at Princeton University, he is particularly known for his research using it Cosmic Microwave BackgroundFaint radiation associated with the Big Bang to determine the fundamental properties of the universe.
He also serves as chairman of the Simons Foundation, a charity that funds research in mathematics and science. But last year he was recruited to pursue a different question: Who or what else might be out there?
It all started during a ski trip. Sperkel was on the slopes with Thomas Zurbuchen, the former head of NASA’s Science Operations, when Zurbuchen asked for a favor: He was looking for someone to lead NASA’s Independent Study of Unidentified Anomalous Phenomena. The agency called it a „roadmap” for collecting data on UAPs — unidentified flying objects (previously sometimes called UFOs, for unidentified flying objects).
„It’s not something I plan to do,” Spergel said. „But NASA has done so much for my life, and if they ask for something, you go help.”
Published by the group Final report Last month, while there was no evidence of extraterrestrials visiting Earth, there were plenty of unusual phenomena (some natural and some man-made) in the skies above us. As more data is collected, scientists will be better equipped to understand such phenomena, the report says.
On the same day, NASA declared Its new director of UAP research, Mark McInerney, was previously the agency’s liaison to the Department of Defense on UAP matters. With that, Sperkel and the rest of his team returned to their usual research. „We have fulfilled our charter,” he wrote in an email to Undark, later adding: „Happy to help NASA with this – learned a lot, worked with good people, no regrets.”
Recently, he discussed the team’s performance. Our interview was conducted via Zoom and email, and edited for length and clarity.
UNDARC: UAP stands for UFO – Unidentified Flying Object – so-called renaming aimed at reducing stigma. Is this part of the renaming?
David Spergel: This is in part an exercise in renaming. I think this is an exercise in being more precise. Because many of these items may not fly. Of course, some of them float. A few instances are of course balloons, drones, airplanes. Some clouds.
Some phenomena are not well understood – but some of them, when you look at them, have conventional explanations.
UD: You’ve gone on record as saying that there’s no reason to think we’re talking about an extraterrestrial origin, even if there’s something unexplained.
DS: That’s right. You start with the usual stuff first.
UD: People have mentioned the stigma associated with an airline pilot or a military pilot wanting to report something. So what might change going forward? Is it just the idea that everything should be transparent?
DS: Yes. I think the U.S. military is interested in collecting data on events, and NASA has set up this group — one of the messages I think should be given to pilots in particular, but to people in general: You see something unusual, collect information about it, and report it.
Now I think some of these, especially on the military side, may have military applications. That Chinese balloon It moved across Canada and the U.S. — those balloons were almost certainly seen by commercial and military pilots from Guam and were not reported. In both Ukraine and Russia, there are apps for the public to report drones. So one of the ways that the Russians stop the Ukrainian drones is that the Ukrainians stop the Russian drones and the public sees them flying overhead and then there’s an app to report information about where it is.
So these are the usual things. But I think in terms of potential use for it, but also as a way to educate the public about how we should act when we see something that we don’t understand – we shouldn’t ignore it. We should at least report it; Collect data about it.
We should not jump to the conclusion that anything we do not understand must be attractive. But it does mean it needs to be thought about more. One of the things we hear from pilots is a very real fear of being ridiculed and losing their job for reporting anomalies.
UD: Are you concerned that if NASA focuses on UAPs, that will legitimize speculation about aliens and flying saucers?
DS: In a sense, we were trying to walk a tightrope between the two communities. You have some colleagues who feel that even discussing this topic is inappropriate and brings legitimacy to it. Others, on the other hand, felt that there was a wider conspiracy of hidden alien sites, and if we didn’t reveal NASA’s hidden alien sites, we were shutting things down.
UT: Who said that?
DS: People on Twitter. The strange world of the Twitterverse. That is, it is a topic that scientists like Avi Loeb have voiced. I hope we’ve achieved this – taking a more balanced approach so that you don’t immediately jump to too exciting a conclusion. But we scientists also don’t want to say: “Oh, you’re seeing something different. We don’t want to hear about it. I think that is wrong.
UD: Can you tell us a little more about the role that the public can play?
DS: So our suggestion is that NASA might do it in-house, but I think we might contract some company to develop the smartphone app. Your smartphone starts with a good camera. The software records GPS, it records time, it records the local magnetic field, it certainly measures sound, gravity.
So you can imagine recording it all, embedding it with proper metadata, watermarking it, and uploading it to a website without being so easily edited and cheated. If you do that and it’s sorted by GPS position and time, you can ask, are there reports from four or five different independent observers? Then you can get 3D — actually 3-plus-1D — information, and figure out how far away the object is, how fast it’s moving, and so on.
Most events are routine. But even if you really believe the odds are there, you want to get them. The first step is to understand what is normal. An analogy I like to make—and I think about how we do machine learning—is if I want to find a needle in a haystack, I have two options: I know what the needle looks like, and then I use a Matched filter Ideal for finding needles; Or I know what hay looks like and I’m looking for things that don’t look like hay.
Imagine that there is something that turns out to be an airplane or a balloon. And in four different pictures, it’s very clearly a balloon. But from a direction where the sun is behind, or in some way, it looks really fresh. And we learn that balloons look a certain way and stay that way. That means when you see something like this in another data set, you’ve learned from it. With the straw analogy, „hey it might seem that way” is what I think about it. Also, you need to generate that data to identify what are truly anomalous events.
UT: NASA has always struggled with its budget. So is this way of UAP research a good use of public money?
DS: I think this can be done at low cost. I didn’t want it to be a big, expensive project. One of NASA’s jobs is to educate the public about science. And it’s a teachable moment in a way.
UT: Do you have any idea how much NASA would budget for this?
DS: This report informs NASA planning and budgeting, but I have no role in their budget planning. Nicky Fox [head of NASA’s Science Mission Directorate] NASA will be the main „decider” on the budget submitted.
Ultimately, Congress sets NASA’s budget. Based on the interest in that area, they may even place a line item. Given the dysfunctional state of Congress at the moment, it’s hard to know.
UD: What are the odds that there are some smart people out there somewhere?
DS: I do not know. I like to think about things we know. What we’ve learned in the last 20-some-odd years is that planets are remarkably common. So we know that there are roughly as many planets in our galaxy as there are stars. And there are vastly more Earth-like planets out there, no question.
What we don’t know, I would say, is biology and politics. Given an Earth-like environment, how often does simple life emerge? How often does a simple life become complicated? And then how long do political, complex societies last? Do they destroy themselves? Or have they persisted for billions of years? We don’t know.
I see that nearby stars are usually a billion years older than the Sun or a billion years younger. So any life in a nearby star system may have evolved a billion years more than us, or a billion years less.
If it’s less, you know, it’s a simple bacteria-like form. Then there’s the possibility of something more complex – but if there is something more complex, it’s probably a billion years ahead of us.
I think about it in Earth terms: Go back to 1923, and you explain to today’s society – what our airplanes and cars and telephones look like. They said, “Wow, 100 years; Things have progressed, but I understand how society is. Go back to 1023, you’re a witch, right? You describe flying in the sky and talking to distant people, computers. At 1023, there is no meaning.
Now, I have to imagine that the step from 1023 to today is no different from the step from today to 3023. And a billion years is a million steps. If there are intelligent aliens, if they come to Earth, they are far more advanced than us, and that would represent a step and difference between us and bacteria or yeast or something.
So I think it’s very unlikely that aliens will come here and have flying vehicles similar to the technology we have today. They can be very advanced. Almost certainly, they will be capable of doing things that we cannot detect.
I doubt aliens exist, whether they like to see or not. If they were to see, we would have seen them by now.
