Show this for a laugh to your colleges...Australia, QLD, midcoast Feb 2008 between 4-5pm my children yelled for me to see something in the sky, I replied its a plane not wanting to be bothered and they yelled back it was to big so I bolted to the front yard and saw them pointing to a dark hazy mass high in the east about the size of half the moon and it was rapidly with each second getting larger, I was baffled to what it was and watched as it grew in seconds and blanketed half the sky in broad daylight like a shadow, I had no idea what was going on and then it clarified into perfect detail, absolutely perfect detail, it was a coal black asteroid or as it appeared a chunk of a black moon or even planet such was its size, it was no formless rock, for size I was an ant watching a freight train go by at incredible speed for something so mind boggling immense almost beyond human comprehension in size, it seemed to me bigger than the earth, the most fantastic, incredible and dread sight ever seen by a human in all of time, the angle of the afternoon sunlight illuminated its facing surface and side cliffs but it did not reflect light, it was shadow black despite direct sunlight, the facing surface stretched away not ending blanketing half the sky the entire time and the side cliffs went up and up what seemed thousands of kilometres without ending and just fading not ending as they went on and on by at incredible speed, ;like an ant watching a train go by, my first thought on realising what it was I was seeing was to get the camera but I realised two things as well, first it was going too fast and I would miss it if I tried and that it was probably the end of the world or so it seemed so I just decided to watch and soak it up, plainly it was a chunk of a much larger object if you can picture a chunk of a dark moon\planet\comet with surface facing and all the way to the core showing as side cliffs.. almost beyond comprehension in size, and still imprinted in my mind, the whole show lasted about 10 seconds or so before it abruptly faded away, completely astounded for a while, completely astounded when no mention or trace could be found in the following days, weeks, months, years, astounded at the level of vitriolic hate I received for telling this tale so I stopped and said nothing more for several years except that soon we will see a new space race and to Mars within a decade which also drew mockery and derision at the time as also impossible in the time frame I claimed.Then in feb 2017 I read a russian astronomer claimed we have a massive asteroid on an intersect orbit and we are all being deceived to its existence, that much I can attest to, it missed us by a minute in 08 and not a whisper despite it being unmissable by the space agencies and being 9 years to the month after what I saw seemed more than a coincidence and more like an orbit so I started again.. time will tell if I speak the truth and not much at that.. perhaps we passed through a destroyed ancient solar system system and this and oumuanua were part of it.

i saw a UFO in broad Daylight Years ago...i was convinced !

Well said 👏

I remember his first appearance on TSAN and at first I wasn't too sure about him, I soon changed that opinion and think he's more than worthy of the honor of being Sir Patrick's successor.

I agree, "a gem of a lecture" 👏

and we have to sift through a lot of fake news to find these gems.

Obviously, it happens all the time on a galactic time scale.

As Chris was saying near the end, they may be far more common, but we are bad at seeing them, as they are dark and moving fast.

Humans have only been observing for a few hundred years though.

@@JonnoPlays Exactly.

@@NondescriptMammal ummmm. if that was a touch of irony. doesn't matter. it is accurately titled. "our" as opposed to "the"...

ADD?

Dumb.

Engaging indeed!!

😊

I do That so often haha

Is it possible to attend such lectures if one is just purely interested in learning about such topics? (I am London based)

Yes it is. Please do visit our website for details on how to book tickets - www.gresham.ac.uk

Yeah, but I think Avi is thinking of solar sails and that would still be accelerating the craft when observing it at some distance from the sun.

Occam's Razor: it was an asteroid.

Within range of earth's sensors?? No way! Lol

Encountering an alien spacecraft would be a black swan event - we would be forced ​to admit Occam is inadequate to reason correctly? @@gdutfulkbhh7537

​@gdutfulkbhh7537 seeing how one must assume the theory of rogue planetecimals to be true coupled with atypical shape and movement, I'm not entirely sure Occams Razor supports this 100%. However, it being a rouge asteroid is a slightly more simple possibility, so you're correct at face value.

Also why have we not seen 3-lump objects? Maybe we will soon.

Exploding stars. But that was before the solar system formed.

You had me at "The earth is flat..."

@@japhfo Yeah and they seem to think the universe is flat too. It is overall but not for each individual galaxy.

Still, you’re not going to get to the speed of light much less exceed it.

@@zz-nc5kx The speed of light is never exceeded. It’s that time and distance change. This makes light arrive faster.

Yes, that’s right. Essentially it didn’t slow as much as expected

BOB (Ball Of Bit's)

There's a supermarket trolley already up there.

Huh?

It started with "Pet" rocks!

Scientists can't suppress their wish that it really is aliens.

Not necessarily. Several objects are known with chaotic rotation.

@@ngc-fo5te Likely over a long time, but we only have a few weeks of data.

If it were binary, its path would be much more irregular passing so close to the gravity pull of the Sun. Unless it were rotating very, very fast? It models as a point mass.

Any native object flying around in our solar system is 4.5 billion years old. Statistically speaking, anything coming from outside our solar system is much older. It COULD be only a million years old, but the LIKELIHOOD of that is so close to zero it's not even measurable.

It's a very different beast - it had plenty of ice, which sublimed (turned into gas) when near the Sun, producing an atmosphere (or coma) and tail, so it looks much like a normal comet. It was also larger, so appears as more than a dot. It's not moving fast enough for the galaxy to blur over the course of what I think was a total exposure of an hour or so.

@@chrislintott1 ok. So different exposure time then? But to be honest that galaxy in the "background" seems very weird to get as sharp as the object you want to focus on when the distance is that big. The two photos is like too completely different pictures.

Ah, I understand the question. From a camera’s perspective, everything in space is at infinity, so you can focus on things at wildly different distance at the same time.

Yes but if the foreground object is moving across the field of view, a long exposure will show it blurred if the background galaxy is sharp. If the object is mostly moving directly away from the camer, which it probably was, the amount of blurring will be small.@@chrislintott1

Completely! Listening to him is like I Am Kat is the Kingfisher!

The jokes are for me.

Probably.

Propulsion

That's amazing ! Is propulsion a Gravity MOTION ?

@@jdlflagstone6980 First, we live in Occupied Space, meaning the Photon Energy's of our Solar System that's Enabling MOTION throughout, as it dwindles into Empty Space where there's no Energy to power objects in MOTION, so they turn around to connect with the next strongest Energy signal in it's vicinity, going back home to it origins

Collisions.

Incoming speed was enough to keep it going?

and what do you know? He clearly already said the US AIRFORCE edits the data from the images before the scientists get to analyze the data...

Yup. People love to choose the least possible explanation and leave out facts. It sells books, conference tickets, youtube monetization, tv soecials etc. The carousel of UFO presenters are making a fortune the last few years.
