The Day the Mesozoic Died: The Asteroid That Killed the Dinosaurs - HHMI BioInteractive Video

I am kind of crying right now because these selfless scientists/researchers spent almost all of their life in pursuing knowledge and knowing the unknown, contributing to society's knowledge. Through these people we were able to develop. I am really thinking that I am just an insignificant being by only thinking my own well-being.

[@tsopmocful1958]

@@johnolpenda9803 Please keep in mind that most scientists like these palaeontologists are very passionate about their work, are very interested in the subject, are very curious and are probably the type of people that get a lot of joy simply from solving and completing difficult puzzles of any kind, so their motivations are not completely selfless. Of course their primary aim is to contribute to human knowledge, but they wouldn't be able to to study and work hard at it for years without enjoying it in the first place. People produce the best results if they love the work they do, so gaining a career that matches your natural interests is an excellent achievement in itself. So if you wish to contribute to the world, the best place to start might be to work out what you are most interested in or what activities gives you the most joy and capitalise on it somehow. And if your main love is simply in helping others and you aren't scientifically inclined, there are certainly many options for that, ranging from healthcare to teaching or from charity work to conservation projects. But the main thing to aim for is to love what you are doing, because every day you do it will be a pleasure, which means that putting in lots of hard work and time will never be a problem for you.

We’re basically living in a post apocalyptic world

[@classickruzer1]

When Adam and Eve lived in a paradise Earth and then rebelled against God, this is how God cursed the earth as he had told them he would.. the asteroid hit so hard that it shifted the earth's axis by 23 degrees. If these scientists could figure what angle it came in from, based on the degree of impact, they would know the exact position of the earth when it hit.. That would be interesting and would also confirm the fact that it did cause the earth to shift on it's axis.. It would have had to come in from the South Pole and struck North of the equator..or it would have had to come from the North and struck South of the equator. When the earth shifted, it resulted in the tectonic plates breaking up and pressure from the earth's core releasing massive amounts of pressure that pushed the sea beds up, creating the tsunamis, volcanoes and mountains. At zero degrees tilt, the earth would be a paradise, with it's foundation all intact and very mild seasons, along with perfect tropical like weather... plush foliage throughout the entire earth. Palm trees and other tropical vegetation have been discovered under the ice at the North Pole.. Mastodons found frozen with vegetation still in their mouths under the ice at the North Pole..Proof of a once perfect earth that flourished over the entire planet.. And B T W , there were never any flesh eating dinosaurs.. Scientists base their flesh eating theories on the size and structure of their teeth.. They've found no evidence that dictates any kind of dinosaur dieted on flesh. Those dinosaur that survived the asteroid could have possibly fought others over the scarce vegetation that survived, thus presuming they were flesh eaters... but prior to that, they and all other animals survived on vegetation. Scientists are always looking for something new, which is great, but some do it in order to get recognition for themselves and then convince others to adopt their suggested findings. Just like carbon dating.. determining the amount of carbon 14 in the remains of deceased animals and the rate of decay... It isn't overwhelmingly accepted by all scientists as fool proof.....therefore, their dating of events consistent with fossils and bones of the same era aren't fully accepted as accurate..

That is a vision about the future by Apostle Saint John and it seems to be pretty much the picture of an asteroid impact, of one arriving into one of the oceans.

A large meteor of the size proposed, landing in the site proposed, would necessarily cause a devastating tsunami and an earthquake of some magnitude. Even a relatively small asteroid hitting the Earth today would be detected by seismographs locally, and something measuring less than a hundred metres could be detected globally. These objects have massive amounts of kinetic energy.

An extintion event may not be an event that kills every individual of the spicie, but an event which attacks it in a way that makes it die over time

You will always get comments from people who doubt anything that goes against religious teachings. The Arc that was built in Kentucky several years ago has one display where a human is riding a dinosaur that's about 7 feet tall as if to say that dinosaurs and humans existed at the same time.

I find it hard to believe that most people tend to believe whatever info proclaimed in such documentaries. These supposedly info are based on uncertain theories based on other uncertain theories based on different uncertain theories. Nothing with solid proof. All prepared by atheist scientists on purpose to attack our Holly Bible. They keep on coming with new different theories every 5 - 10 years or more. Every time they claim to have found the true story. Even their time-dating methods are deficient by few millions of years (depending on the items/periods) as they know it but don't admit it except when cornered. Strange that most people tend to believe what they see on TV and on Hollywood of self-claimed true stories. Listen to what they say and the style of their answers where you may detect their own doubtful ideas (or lies) that they promote purposely to fight Christianity/Judaism. They force us and our children to believe in such garbage with no proof except lots of bones and their rich imagination.

Of course there are scientists who get stubborn about certain theories but overall scientists want to search for the truth. When a new, improved theory pops up most scientists adapt and accept it. We don't know until we do. I don't understand why you can't believe in God and also in theories like the ones presented in the video. Consider science the exploration of creation if you want. In this way, science is an act of love to know God's creation. Science and religion are not in opposition to each other necessarily.
