Stupid science Science doesn't know Every second the Sun emits billions billions billions ^ billion lightning 0,1 voltage create sunlight. 1 positron + attracts 1 electron -- create 0,1 volt lightning Positrons + and electrons - rotate very rapidly after 4, 6 billion years of creating the Sun ' s core, so the core of the Sun rotates very quickly like A super large electric turbine that produces super large electrical energy Every second the Sun emits 4,1million tons of electricity create sunlight, sunlight moves the circle back to its original position after 8 hours, so pushes the 8 planet to rotate in order

I kinda think we need this. If an asteroid destroyed a city, I think it might put everything in perspective for people. Imagine a massive asteroid, the size of a moon approaching from behind the sun but it gets sucked in and we never knew. Scary thought.

That awesome professor never failed to surprise me thorough the video: 1. First, he keep a meteorite in his house 😮 2. Then he went on explaining things in his eccentric egg chair 😆 3. Then he showed us his dinosour head decoration in his yard 🤓 4. Finally he used his two favorite countries, France and Germany, as an example on how they can be obliterated by a 1 km size meteorite 😅

Future settlers on Mars will have more to fear from falling asteroids being that the atmosphere is far less capable of burning it up and reducing its size as well as less likely to cause it to explode before reaching the ground. One solution for this as well as to protect against radiation is underground habitats. Earth's moon bases will at least be included in the search for near-Earth asteroids. On earth, would deep bomb shelters help (those very few that have access to one and can get to it in time despite the traffic on the surface)?

This is one of the reasons why space development is so crucial for a long-term and stable society with the scale and technology of modern times. We ever last so long before a globally devastating asteroid hits. Given how ill-prepared and uninterested in the business of shooting down or swerving away approaching asteroids most of us are, we are purposefully making ourselves sitting ducks. Whereas if we had multiple settlements in separate astronomical bodies, with big and sustainable cities and nations already developed, the possibility of a single asteroid destroying or crippling us is greatly reduced. When one is hit by such an asteroid another unaffected settlement can move in to help and restore. And the ones living in that settlement can move to others if an asteroid is found approaching. Its either this or developing asteroid defense systems that can actually do something about ones coming for us.

Honestly, dying by an asteroid would be a true honor. Not many people get to have such a glorious death. I would prefer be on the other side of the planet on impact so that I can burn in dropping lava for a week and scream “You can’t kill me God!”. So epic

17:30 in this case, in a real world scenario, people wouldn't just sit in their cars honking their horns. They would leave their vehicle, tell the driver to put their vehicle in neutral, and help push the car into the ditch. The driver and their family would then probably abandon their vehicle and hitch a ride with any essential belongings with anyone in the millions of drivers behind them with any available space. A state of emergency would likely make it a criminal act to leave anyone stranded on the side of the road if you have space available in your vehicle. Desperation would also make it lawful to ride on top of vehicles and in the back of pickup trucks, semis, etc. without needing any safety equipment, or at least officers would be told not to enforce these types of traffic violations. Even still everything and everyone would be so overwhelmed that the only priority at mind is leave the city as quickly as possible to guarantee the maximum number of people survive as possible, total utilitarian.

First Attack from God) Year 3500 Christ 1st Coming Revelation 9:1 Then the fifth angel sounded: And I saw a star fallen from heaven to the earth(Asteroid came from Heaven's Portal Door). To him was given the key to the bottomless pit(At CERN). 2 And he opened the bottomless pit, and smoke arose out of the pit like the smoke of a great furnace. So the sun and the air were darkened because of the smoke of the pit. 3 Then out of the smoke locusts came upon the earth(Angels of Hades). And to them was given power, as the scorpions of the earth have power. 4 They were commanded not to harm the grass of the earth, or any green thing, or any tree, but only those men who do not have the seal of God on their foreheads(Secret). 5 And they were not given authority to kill them, but to torment them for five months. Their torment was like the torment of a scorpion when it strikes a man. 6 In those days men will seek death and will not find it; they will desire to die, and death will flee from them(Zombie apocalypse). (Caused by Asteroid impact) Revelation 16:18-20 And there were voices, and thunders, and lightnings; and there was a great earthquake, such as was not since men were upon the earth, so mighty an earthquake, and so great. 19 And the great city was divided into three parts, and the cities of the nations fell: and great Babylon came in remembrance before God, to give unto her the cup of the wine of the fierceness of his wrath. 20 And every island fled away, and the mountains. were not found. No Safe place to hide in this time the Angels of Hades can go everywhere even in deepest underground bunkers if you wanted to save your future relatives you must do everything to get into Mars Colonies but Martians main goal is to escape outside of our Milky Way galaxy.

i think his math is skewed with his suggestion there is a zero chance within the next 100 years to have a large impactor , because you have to remember we can only monitor 45% of the space because of the sun and our inability to see what's coming form its direction , like the russian meteor .
