This week, the director of the U.S. government’s UFO analysis office stated that there is “evidence” of concerning unidentified flying object activity “in our backyard.” According to physicist Seán Kirkpatrick, who heads the congressionally-mandated All-domain Anomaly Resolution Office, this alarming UFO activity can be attributed to one of two extraordinary sources: either a foreign power or “aliens.”
To be sure, the ramifications of either would be significant. But Kirkpatrick’s comments, which come as he is about to retire after a 27-year defense and intelligence-focused career, are more intriguing because he also says that “none” of the hundreds of military UFO reports analyzed by his office recently “have been positively attributed to foreign activities.”
At the same time, Kirkpatrick and senior defense officials have ruled out the possibility that secret U.S. programs or experimental aircraft explain the phenomena.
I would posit a 3rd possibility:
We already know our solar system is kind of at the ass-end of the Milky Way and distances to get here are VAST. So any intelligence with the capacity to get here would likely find little of actual interest here.
So what advanced technology WOULD have a vested interest in a) studying our culture and b) maintaining as little interference as possible?
Future humans. Somebody cracked time travel and, like good scientists, are studying their ancestors. Just like we use archaeology and paleontology.
From everything we know interstellar travel in less than generational time scales is all but impossible.
The only thing that is more improbable from our current knowledge of physics is…travel back in time.
Occam’s razor: The explanation that requires the fewest assumptions is usually correct.
So we have three possibilities.
A foreign power
Aliens
Time Travel.
…
The boring reality is that it is the first one. A foreign power.
The trick with the foreign power angle is that it would be a foreign power with technology we don’t fully comprehend. I doubt Russia or China is at that level. We know for a fact that North Korea isn’t. Nor is Iran.
So who would it be? Japan? Tech-wise they could surprise us, but why?
And that is still orders of magnitude more likely than time travel or interstellar aliens.
And so is one branch of the US government not talking to another
This map of UFO sightings has the USA at ~250,000 but as soon as you cross the border into mexico you only have…895.
While Europe tops outs at ~20,000.
isnt that map tracking data only from US agencies?
English info only?
It’s those rascals in the hollow earth, I tells ya.
ARTESIANS! I SEEN 'EM!

It could also be US Skunk Works shit. IIRC a bunch of weird sightings in the US some decades ago ended up being the F-117 and that stealth bomber. The public didn’t know about them until years after their development.
That seems more plausible to me than China or whatever.
A random government official not knowing what they are doesn’t say much if they’re black ops projects. By definition, nobody would know about them except the people directly working on them, and they’re not gonna say anything.
I’m most interested in what makes them so sure these aren’t our own. They’re awfully naive if they think they’re allowed to know everything.
Even if they did know what it was, feigning extreme ignorance like this would probably be the better strategy anyway. It would be in the US’ best interest for the waters around all of this to be extremely muddy.
Let me remind you tgat the universe has no obligation to do things as easily as possible. Occam’s razor is at best a way to prioritise your conjectures. It could easily be the dolphin spaceships coming to rescue their peers before climate change kills them.
Sorry, I thought we were talking science not science fiction.
As Carl Sagan said: Extraordinary claims require Extraordinary evidence.
“easily”
Well yeah, i prob went too far there. I just don’t like people defending positions by saying “it’s the easiest explanation so this is it”
If the videos of the tic tac object are accurate, as in what was recorded was really there, I disagree. These things can drop from 80k feet to sea level in a second with no obvious signs of propulsion and no control surfaces.
Yeah that isn’t true. With enough will we could leave the solar system in our lifetime.
Leaving the solar system is less than 1% of the distance to the nearest star.
The Voyager probes have left the solar system. It took about 30 years for them to do it…
The Voyager probes didn’t have a nuclear engine. They had a sad little rocket and some gravity assists. Nor were they designed to go as far as they did. The original mandate was only to Juptiet and Saturn.
In any case nothing is going to happen until the boomers are dead so we can embrace nuclear power and propulsion.
Nuclear thermal engines still need propellent.
And while they have an ISP about 10 times higher than chemical rockets, they are still basically useless for interstellar distances.
Simply because the more you accelerate the more you have to break and you have to carry the propellant for both.
TLDR: the rocket equation is a merciless task master.
You don’t have to carry enough for both. You can solar sail and gravity break.
No you can’t.
Any craft that has enough mass for human travel and is accelerated to even 1% of c would need solar sails that are thousands of square Kms in area to have a hope of decelerating.
That still ends up at a 500+ year trip to Alpha Centauri.
And that is just more added weight you have to accelerate in the first place.
TLDR: the rocket equation is a merciless task master.
Ok show your math. Show that nuclear fueled rocket can never get above 5% light speed in total.
If we cracked time travel then it’s equally possible some other advanced race did too and traveling long distance isn’t an issue if you can manipulate time. Still could be aliens.
Yeah, it’s wild how everyone goes “aliens” when the expansion of the universe sets the vast majority of it as inaccessible without FTL travel, our own signals of life haven’t reached very far yet, and the same underlying tech to travel FTL would also mean traveling in time.
So we have things flying around in formations similar to our own tech and behaviors but seemingly more advanced and showing considerable interest in humans.
Time travel at least deserves to be on the discussion table as much or more than aliens.
Time travel to the past is orders of magnitude more unlikely than alien life existing at the same time as us. We know interstellar travel is physically possible, just very difficult, while our current knowledge of physics shows that time travel to the past is physically impossible.
I think it’s more likely that if these objects are extraterrestrial that could be uncrewed drones meant to perform basic science/reconnaissance. It’s even possible the civilization that launched them is long dead due to the distances involved and that’s why they aren’t contacting us.
That said, I also wouldn’t assume that we’re uninteresting. Any form of life that demonstrates intelligence is probably rare, so simply observing us out of curiosity would make sense too.
You misunderstood.
The issue isn’t whether it’s possible to travel interstellar.
It’s that the rate at which the universe is expanding means that even if you could travel at the speed of light, the majority of the observable universe could never be visited. Traveling slower than the speed of light, and even more is permanently inaccessible.
Additionally, we’ve only been generating ‘interesting’ signals that could be detected for only around 100 years.
Assuming those signals could still be read somehow at a decent signal to noise ratio maximally far from us, that’s still only around 10,000 star systems within a 100 light year radius around us.
Given the speed at which less than light speed interstellar travel would occur plus the time to reach us after receiving an interesting signal, and you are talking about maybe around a 30 light year radius that’s practically the range at which any alien life would have received a radio signal from Earth and been able to arrive to check it out.
Given credible sightings go back to the mid 20th century, that reduces the practical range to more like a 10 light year radius to get a signal and come check it out using conventional interstellar travel.
There’s like 30 star systems in that range.
We’re currently using spectroscopy to try and find possible bio signatures.
Which our planet has had for anyone looking, for oh, several million years longer than our radio broadcasts, which have largely stopped
I like this idea, but it doesn’t hold up either. We know that time travel is technically possible, but only in one direction - you can only move forward in time, never backwards. So, if a craft left earth and set out into that vast ocean of space only to return after a good long time of visiting other worlds, those aboard that craft would return to an earth that has experienced much more time passing. To those on the ship, it would appear that the ship really wouldn’t have been gone for that long, while to those of us poor saps stuck in the gravity well, a metric crap ton of time would have passed on earth before we’d ever see that ship again.
A simple guide to time travel
Edit: After thinking about this some more, the exception to this would be if a craft left earth tens of thousands of years ago. If that were the case, they could be returning now to a world completely unknown to them, which would absolutely warrant an observation-only kind of reaction. However, we don’t have a whole lot of evidence for a lost-in-time advanced society. There’s a couple of interesting things that have popped up in history, sure, but nothing to suggest a civilization advanced enough to have achieved space travel, so again, though it’s not outside the realm of possibility, it’s extremely unlikely.
If they could do that why do they get caught? They would presumably know from the historical records us seeing them.
Depends on how time travel works.
What happens if you think of it more along the lines of Everettian many worlds?
You can go back in time to a point that’s n moments before your own time and accurately represents the universe at that point in your history, but then as soon as you are there you start splitting off into a new fractalization of timelines.
Which would also make it effectively impossible to get back to your own time or influence its events.
I am alright
