Texas A&M University astronomer Nick Suntzeff has been involved with space research for 30 years and spent 20 years in Chile, where he helped co-discover dark matter. Below, he offers his thoughts about UFOs and whether or not we are alone in the universe.

What can we expect from the government’s official UFO report?

I have no idea what the report will say, but I doubt they have any evidence where a UAP (Unidentified Aerial Phenomenon, previously called a UFO) is clearly resolved. For starters, have you ever noticed that UAP images and videos are usually out of focus?

In the recent videos that are now getting a lot of attention called FLIR1, Gimbal, Triangle, and GoFast, for instance, let’s consider the triangular UFO. In the video you can also see other objects that are triangles. Are these sister UFOs? No. What this means is that the camera was out of focus and the camera pupil (shutter) was triangular. One person has measured the positions of the faint triangles (and one bright one) and shown that they are at the positions of the stars near the constellation Taurus and the planet Jupiter. Also, this UFO blinks in the same way a commercial aircraft does. It was taken off the coast of Los Angeles where there are lots of air traffic. It is an out-of-focus video taken with an infrared camera.

This is one example of an explanation that fits the data. Now, why did the Navy not provide this explanation? They should have asked an astronomer before releasing the video because they could have quickly shown that this an out of focus image.

So does that mean the UFOs are not real?

Well, you can often debunk one story, but you will then get another story and someone will say, “okay, but explain this one.”

In one video, a pilot said the UFO resembled a large Tic Tac mint and that it was defying the laws of physics over the ocean and moving fast. The problem here is that we don’t know how far away it was. If it was high above the ocean, then the apparent motion is likely due to the airplane and not the object.

This is called parallax. You can often find answers like this, and so on.

So I am not optimistic that we will be shown extraordinary evidence where there is no natural explanation for what is seen.

So you are saying that you can rule out most UFO sightings as something else and not a UFO?

There are often simple, but boring answers. For example, the most common UFO is the planet Venus. Once I got a phone call from an excited person who was telling me they can see a UFO right now. It is moving back and forth, and sometimes it suddenly comes closer and then moves away. I asked them if they could still see it. Yes! So I drove down to the parking lot and there was a group of people bunched together pointing up to the sky. I went over there and asked them to show me where it is. I look up there, and it is Venus. I tell them it is Venus. I look at it and it is not moving. It was twinkling a bit but otherwise, nothing unusual. As we looked, they admitted it was not moving, but I was assured that it was before I got there.

Many people are convinced that these UFOs are visitors from another planet, that they have been monitoring the Earth for decades and they are real. If true, it would be perhaps the biggest story of all time. Is it possible?

I can’t rule out we have visitors from other planets. But we need clear evidence. We need a clear photo, for instance. So far, we do not have such evidence.

Note that many reports say that the UFO object was a certain size and moving at a certain speed. Now, if you don’t know what the object is, you can’t know how far away it is, or how big it is. Anyone who says they know the size (unless it landed and left a mark) is, well, not understanding simple optics. So once again, we need clearer proof. I have seen lots of weird things in the sky – very weird things – but I can always explain them.

As for intelligent life – in a way it is a strange question. As the great physicist Enrico Fermi was claimed to have said, “Well, where are they?” That is, if there is intelligent life, why don’t we see it with our telescopes, or see evidence here on Earth of visitations? Astronomers are always looking for life elsewhere in the universe.

Any shred of truth to the long-held rumors that the government has been hiding pieces of crashed UFOs and perhaps even bodies?

If they do, this is the best kept secret ever. Our government is not great at keeping secrets, and this one would be a doozy. No, I don’t believe there is any physical evidence. I don’t think intelligent civilizations could travel the thousands of light years to the earth, and then crash their spacecraft. If they can travel that distance, I seriously doubt they would be this careless.

It seems like the scientific community has always been more than a little reluctant to talk about UFOs. Why is that?

We are not reluctant to talk about it. There are a number of astronomers actively looking for signs of intelligent life out there. It is a real field in astronomy. The problem is that one cannot get government funding to study UFOs. So those astronomers look to the private sector to do the studies. A very close friend of mine, now retired, built his own observatory and is searching for intelligent signals. He got this funded by some rich person in Silicon Valley. If there were sources of steady funding, I am sure a lot of young astronomers would take a job searching for intelligent life.

Any other thoughts you may have about UFOs?

This is a thought experiment. We are not too far –maybe 100 years or so – from building mini-satellites, accelerating them up to 10% the speed of light using lasers, and sending them off to nearby stars. We could make billions of them – after all, we have made billions of cell phones so far. With laser acceleration and light-weight satellites (10 grams or so), we could launch these to billions of stars. The satellite could have a radio transmitter beeping the first 10 Fibonacci numbers (numbers used to create a mathematical sequence) showing it must be artificial.

If I can imagine this future technology which is not far from what we have today, the question is, why is there no satellite from another civilization that has passed this way, and beeped at us?

The only fact we are certain of is that so far — and we are looking hard — it is silent out there.

Contacting aliens ‘could end all life on earth’ warns physicist

It’s been an interesting topic of discussion for centuries that we are alone out here in the universe.

But according to a physicist and science writer, that might be for the best.

Mark Buchanan is a well-known and accomplished physicist and science author, and he thinks contacting aliens ‘could end all life on Earth’.

His remarks come after much excitement (and dread) arose recently over the sightings of UFOs by the US Navy in 2020 and in general. Known as Unexplained Aerial Phenomena (UAP), The US navy saw flying objects travelling and moving unlike anything mankind has made.

Many suggest this is proof of alien existence, but Buchanan isn’t so eager to find out.

He writes in the Washington Post: ‘Chances are, we should all be grateful that we don’t yet have any evidence of contact with alien civilisations.

‘Attempting to communicate with extraterrestrials, if they do exist, could be extremely dangerous for us.

‘The search for aliens has reached a stage of technological sophistication and associated risk that it needs strict regulation at national and international levels. Without oversight, even one person — with access to powerful transmitting technology — could take actions affecting the future of the entire planet.’

As Buchanan sees it, if we were to meet aliens, they would be far more advanced than ourselves. It would be like Darth Vader meeting Fred Flintstone!

Buchanan continues, ‘Most stars in our galaxy are much older than the sun. If civilisations arise fairly frequently on some planets, then there ought to be many civilisations in our galaxy millions of years more advanced than our own. Many of these would likely have taken significant steps to begin exploring and possibly colonising the galaxy.

‘Our history on Earth has given us many examples of what can happen when civilisations with unequal technology meet — generally, the technologically more advanced has destroyed or enslaved the other.’

Some scientists doubt there are any aliens to begin with. The SETI (search for extra-terrestrial intelligence) organisation has been searching for 60 years with radio telescopes. They have found nothing.

Nick Longrich, lecturer of palaeontology and evolutionary biology at the University of Bath, thinks we just might be a fluke, ‘Our evolution may have been like winning the lottery … only far less likely’.

If the universe is so large and so old, then where is everybody else? This is called the Fermi Paradox and it has troubled us for a while now.

If we discover that there is other intelligent life out there, that would no doubt be a world changing, even humanity changing event.

If we are really alone out here, well then at least we wont have to worry about an alien invasion.
