    The class “Dinosauria” was originally defined by “Sir” Richard Owen of the Royal Society, and Superintendent of the British Museum Natural History Department in 1842. In other words, the existence of dinosaurs was first speculatively hypothesized by a knighted museum-head “coincidentally” in the mid-19th century, during the heyday of evolutionism, before a single dinosaur fossil had ever been found. The Masonic media and mainstream press worldwide got to work hyping stories of these supposed long-lost animals, and then lo and behold, 12 years later in 1854, Ferdinand Vandiveer Hayden during his exploration of the upper Missouri River, found “proof” of Owen’s theory! A few unidentified teeth he mailed to leading palaeontologist Joseph Leidy, who several years later declared them to be from an ancient extinct “Trachodon,” dinosaur

    What what I don't understand is that we go/orbit around the Sun while we spin on our Earth's axis so where would these asteroids be that cannot be seen because we are blinded by the Sun? It makes sense that it would have to be asteroids outside the solar system? So there's two asteroid belts right? 1 that is as far as Saturn and one outside the solar system? And is it these two locations that we are primarily concerned with? I was entertaining the possibility that there is a link between asteroids and this mismanagement of covid-19 and other psychosocial and socioeconomic engineering factors period was just seem a little bit quite a bit unsound actually, and I thought that if something could explain the inanity of the past years mismanagement Globes societal factors that perhaps an asteroid would explain it. Catch my drift?

    Why have I not seen this professor before? He should have or has been on other documentaries before. His home is cool. And the meteorite he showed is probably worth a fortune. And I just took a quick look on Wikipedia about him, this dude is brilliant. He’s partly responsible for finding an object way out there beyond Pluto, the first to do so. Part of why Pluto was demoted to a dwarf planet. Which it would seem he might disagree with a bit. He said something like, just because a dog is small, does that mean it’s no longer a dog? IMO a planet, it could be basically anything that has enough gravity to which it basically forms into a spherical shape. Anything too small won’t become a sphere. Moons are small, but they have enough gravity to be spherical. So I guess dwarf planet would be a correct term. But why demote them just because they are small? Pluto has what, 5 moons? And that says it is still not a planet? I don’t care, but I don’t understand what demoted Pluto from being a planet.

    What if the way man made satellites experience a causality effect that requires their chronology to be altered to represent relative time space positioning to Earth, asteroid would need the same consideration. At some point it sounds like I think an asteroid can come from the past or the future into the present without notice.

    why did you not mention comets? Yes, they are quite rare, but considering their long orbits, especially for the trans neptuinian ones, whom we see once in thousands of years, and no trajectory can be calculated until we see it, i think they are the most dangerous objects.

    12:10 I would like to correct the info. Although there are no known 10+ km impactors moving AROUND the Sun that could hit the Earth in the next 100 years, there MAY be such large objects coming in from outside the Solar System at incredibly high speeds (substantially higher than the regular atmospheric entry speeds of tens of kilometres per second). Therefore, the probability of getting wiped out by such an impact during our lives is NOT zero, just very very very very very close to zero. :-)

    If we could detect the asteroid fifty to a hundred years earlier the rocket attaching idea could really work, since small changes in trajectory has a big relevance if it's way sooner. That is if we detect it decades ahead but if it's here a day after then there's nothing much we can do really.

      You better make them really tiny. Or you just make it a lot worse by having multiple hits. And you don't just break them into " tiny bits". Not even small ones. Let alone kilometer sizes. They talk about all that. What's usually proposed as option is to detonate your bombs or do soemthing near it to nudge it's ortbit a bit off-earth course. . If you see it early enough. Meaning decades. The later, the fewer options. If you see it just months before it hits,, you calculate, where it hits, evacuate the countries around that area and find a nice church of your religion of choice.
