Get Known if you don't have an account. Is there a "Brittany" on the no-fly list? Yes, with cats. That sounds like her. OK, just making sure you were aware.

The people wailed and cowered in terror as its wings blotted out the Sun. Alt Text : Dinosaurs loving money is the root of all evil. Main text: Melting ice takes a lot of energy, but the ice in this scenario would be spread out in thin strands across the country, so it would all melt pretty fast. Footnote [3]: Woah, I can nest footnotes! This looks like the map for a game where I would ignore the objectives and just sail around. Offscreen: OK, did you really pay no attention in chemistry class?

Randall: I tried! But there was this really cool bird outside the window. Alt Text : 'It was this huge hawk eating a pigeon! This means they penetrate your body to various depths, heat your internal organs, and ionize your DNA, causing irreversible damage before they even start burning you.

Looking back, I notice that I started this paragraph with "there's some good news. Image of Randall sitting at his computer desk with questioneer Zoe Cutler behind him. Randall : I would have an excuse to quote Arnold Schwarzenegger 's Mr. Alt Text : i do not want to go to space today. Gero Walter: Could a high-speed train run through a vertical loop, like a rollercoaster, with the passengers staying comfortable?

Randall: No. Will Evans: I was absentmindedly stirring a cup of hot tea, when I got to thinking, "aren't I actually adding kinetic energy into this cup? Would I be able to boil a cup of water by stirring? Michael Marmol: If we could convert the energy to build the Great Pyramid, would it be enough to send a rocket to the Moon and back? Lawrence River Adaptive Management Committee. Also, the Earth would be destroyed. Randall: If it's going fast enough, a feather can absolutely knock you over.

Can you just pitch like a normal person? Alt Text : We've been standing here since that last article like five months ago. Why do you do this to us?? Alt Text : At least the teacup wasn't half empty. A careful reading of official Major League Baseball Rule 6. These fragments would be going so fast that when they hit air molecules, they would trigger two or three more rounds of fusion. After about 70 nanoseconds the ball would arrive at home plate. Collisions with the air would have eaten the ball away almost completely, and it would now be a bullet-shaped cloud of expanding plasma mainly carbon, oxygen, hydrogen, and nitrogen ramming into the air and triggering more fusion as it went.

The shell of x-rays would hit the batter first, and a handful of nanoseconds later the debris cloud would hit. When it would reach home plate, the center of the cloud would still be moving at an appreciable fraction of the speed of light. It would hit the bat first, but then the batter, plate, and catcher would all be scooped up and carried backward through the backstop as they disintegrated. The shell of x-rays and superheated plasma would expand outward and upward, swallowing the backstop, both teams, the stands, and the surrounding neighborhood— all in the first microsecond.

The first thing you would see would be a blinding light, far outshining the sun. This would gradually fade over the course of a few seconds, and a growing fireball would rise into a mushroom cloud.

Then, with a great roar, the blast wave would arrive, tearing up trees and shredding houses. Everything within roughly a mile of the park would be leveled, and a firestorm would engulf the surrounding city. The baseball diamond, now a sizable crater, would be centered a few hundred feet behind the former location of the backstop.

Major League Baseball Rule 6. What would happen if everyone on Earth stood as close to each other as they could and jumped, everyone landing on the ground at the same instant? This is one the most popular questions submitted through my website. They cover the kinematics pretty well. This crowd takes up an area the size of Rhode Island. Earth outweighs us by a factor of over ten trillion. On average, we humans can vertically jump maybe half a meter on a good day.

A slight pulse of pressure spreads through the North American continental crust and dissipates with little effect. The sound of all those feet hitting the ground creates a loud, drawn-out roar lasting many seconds. A cell phone comes out of a pocket. Outside Rhode Island, abandoned machinery begins grinding to a halt. Tides vary inversely as the third power of the distance between the worlds. Therefore, when they were young, the Moon would have been spiraling away and Earth would have been slowing down much faster than they are today.

Taking this into account, tides created by the Sun on Earth without the Moon over the past 4. As noted above, every new world I have created provides deeper understanding of our present world: I gained insights into the relative simplicity of our present tidal cycle from What if the Earth had Two Moons?
