I too am highly sceptical. Mainly for two reasons.
1. It pre-supposes that there is intelligent life on another planet.
2. And that planet is not that far away.
The laws of physics are universal.
Interplanetary travel in our small solar system takes ages with the maximum speed of up to 25,000 mph. And that is only possible using other planets or their moons to use as a slingshot to accelerate. And even that is only a minute fraction of the speed of light.

To be able to come here from another star tens or hundreds of light years away, even at a few percent of the speed of light would take take an incredible amount of time. They are hardly likely to go to that effort without a very pressing reason. So extremely improbable that they would do all that without making some kind of impact here that we would quickly recognise.
There are possible ways of bending spacetime to arrive quicker.

Also - it would be relatively easy to populate the galaxy using solar sails in a few million years no?

Most animals will in all likelihood not discover knowledge humans have, and they will never know they didn't. There's a difference between humans and other species on earth, but still, it's not inconceivable to imagine there being knowledge out there humans will never discover, and never know they didn't. Considering the size and age of this galaxy, intelligent life having spawned before us, will likely have had ample time to find us if they "wanted". Also, technology a million years down human evolution, let alone alien, would probably look like magic or be unrecognisable to us. If they exist out there, didn't end themselves and or still find exploration interesting, they're probably already here a long time ago, I say.

We don't fully understand spacetime and gravity according to quantum theory. We think the laws of physics are universal and a lot of the constants we can be sure of, but it's not a definitive yes.

That's not a given at all. It might be literally impossible, no matter how powerful you are.

Yep, that's true. This is why the Fermi Paradox is a thing. The galaxy should be absolutely full of life, and yet we've seen exactly zero indication that there's any out there. We've got a lot of fancy techniques to figure out stuff through telescopes, so if anything was near us (in galactic terms) we would expect to have seen some signs by now. Certainly we think we'd be able to detect a Dyson Sphere, for example. And yet there's nothing. It's a bit worrying, really.

With the emphasis on possible. Yes.
But my point, while thinking about the distance and time was to consider that any such venture would need a purpose to justify it.
So what do we think would be such a purpose.

Yeah the fermi paradox is fecked. I'm coming round to the idea that time is a bigger factor than the number of stars. Chances of two intelligences coming about in the same million or so years outweighs the sheer amount of possible birthplaces. Or something to that effect. Think that would tie itself to the great filter idea.

Yeah, I tend to think life might be ridiculously unlikely to happen in the first place, so when it does happen it's probably far away in time and space to others. That'd be the good news for us, since that could mean we're destined to basically colonize the galaxy. If we make it that far.

We don't really even understand gravity that well.

Doesn't the drake equation account for al of that?

If by possible you mean there are conjectured and entirely unproven ways to bend spacetime that require colossal levels of an unknown, purely imaginary type of energy... Then yes.

It is a way of looking at how the probability of each factor would alter how many advanced civilisations there could be in the milky way. As many of the factors can't really be known (due largely to us having a sample size of 1) it isn't a predictive tool and merely helps us think about the Fermi Paradox.

Mick West's explanation for the Gimbal video is absolutely nuts. The glare of the engines of a jet in front of them. :lol:
You can actually see a clear outline of the object and what would appear to be cold air around it.
He might as well have mentioned swamp gas reflecting off of Venus...

You must have a different video than me, because there's definitely no clear outline in mine. Not sure what you mean by "cold air around it", or how you could even possibly tell that from that video. Do you have a source for that claim, someone explaining the technical details?

Maybe he's talking about how aliens are real and they banged my mum. FACT.

Go ahead and explain that through IR cameras and optical illusions/effects.

It's almost like you can see the outline of a plane in that second gif you posted but not in the first :lol:
Are you serious? They're not meant to be 100% equivalents, I thought that was obvious. It's a difference of scale, video quality and conditions. But what the gif does show is that what you called "apparent cold air" is an artefact of the camera (as well as the glare shape and the gimbal rotation - hence why the video is called gimbal in the first place and not clear outline of an object and what appears to be cold air around it).

If you click on the video I linked you'll also see an example where you can't see the outline of the plane in IR, you see the same black shape.

This post is a joke, right?
He used the laughing smiley, so it must be. You're only allowed to use that one when making a joke.

If you want to be sarcastic, you may use :rolleyes: or :houllier:, while if you're being cheeky you use :angel: or :p. I'm pretty sure it's in the style guide, or someone has to have a word with Niall.

For balance thought I’d respond to a guardian article with a spectator one…never thought I’d be leaning team spectator.

https://www.spectator.co.uk/article/its-getting-harder-to-laugh-off-the-idea-of-ufos
This excerpt is precisly my feel on the "debunkings"
Curiously, however, the situation with UAPs now appears to have reversed these roles. The calm rational debunkers in this instance are the pilots themselves. The people who were there. The alternative theories they are debunking seem embarrassingly over-emotional. Weather balloons and Chinese drones, seagulls and optical illusions! As these pilots wearily point out, they can actually tell the difference between a seagull, say, and a machine moving faster than an F-18 then disappearing instantaneously.

And this is why the evidence is so crap. There’s nothing new here. The evidence is precisely as unreliable as it has ever been. The arguments are as woolly as ever. The credulous get over excited all over again. All that’s different is there’s a new generation of ufologists and journalists to make hay. It’s the same old rubbish about blurry photos and experts who aren’t, and it’s a bit tediously familiar.

I don't know what you mean nick. This time we have. . . let me check my notes . . . eyewitness accounts and blurry videos.

Totally different.
When I was a kid I was into all this stuff, before I learned critical thinking. I read this book called the Flying Saucerers by Arthur Shuttlewood, a renowned ufologist back in the day. It was the biggest load of bollocks I’ve ever read, absolute castles in the sky stuff based on I can only assume taking too much acid and then looking thru telescopes. It was so ridiculous it killed my interest in ufos for good. I highly recommend it if you want to understand the belief system of these guys, and completely vaccinate yourself against it.

I wonder if only you hadn't picked a book written by the Features Editor of the weekly Warminster Journal (occasional contributor of the Daily Mirror and The Warminster UFO Newsletter), author of such titles as Key to the New Age, that another writer wouldn't have burst the bubble of your burgeoning and enquiring mind.

Well, we lost another one to Shuttlewood. :(*

The only gimbal in this thread is you ha : )

: a device that permits a body to incline freely in any direction or suspends it so that it will remain level when its support is tipped —usually used in plural

feck it I'll take it.
A gimbal is a pivoted support that permits rotation of an object about an axis.
