What would happen if ... (15 photos)

Each person comes to mind sometimes unexpected questions about "what it would be if?". Here are answers to some of them.

1. What would happen if the Earth were twice?






If the diameter of the planet was 16,000 km, the mass would be increased by 8 times, and the force of gravity would be twice as strong. All the plants and animals that exist today, would have perished under the weight of its own weight, and there would be new species. 2. What would happen if the world there is another view similar to a man?




If our planet was inhabited by another, as technologically savvy kind of creatures like humans, it would be between us is a constant struggle for power. If, after hundreds of thousands of years of struggle, no one would have won, we would have started to adapt to each other, or would ignore each other.

3. What would happen if a giant asteroid killed the dinosaurs?




If the asteroid fell to Earth, the dinosaurs, in all likelihood, would still be ruled by the planet. Eventually, the prevalence of dinosaurs in the world - it is out of the ordinary event. Researchers have suggested that instead of people there to "dinozavroidy" which would possess a relatively large brain, begin to develop in the latter appeared on Earth dinosaurs.

4. What would happen if everyone in the world jumped at the same time?




If all people would gather together and at the same time jumped, it would make the earth move at one-hundredth of the radius of the side, but on the landing, Earth would return back.

5. What would happen if the moon had not yet formed?




Huge tides generated by the moon, whose orbit was much closer to Earth during its formation, bordering the "chemical" building blocks involved in the origin of life. Without it there would be no life or living things would have developed very different patterns of behavior in order to cope with the six-hour day and extreme climatic changes that would exist under a moonless Earth.

6. What would happen if people were twice smarter?



In this case, according to experts, we would be more developed at the individual level, would be healthier, to look better and be less religious. Nevertheless, you still would differ from each other, and the society would be as contentious as it is today.

7. What would happen if all the cats in the world died suddenly?



Cats may seem ordinary, meaningless animals, but they are vital members of the global ecosystem. Through research, which studied the effects of withdrawal from the territories cats small islands, we know that without them the Earth would be promptly invaded by rodents. Mice and rats probably would have destroyed all stocks of grain, spread to a large number of diseases and destroyed to ground-nesting birds.

8. What would happen if our solar system was formed would be closer to the edge of the Milky Way?



Although on the edge of the galaxy there is only about a third of all metallic elements, as compared to the place where we are, life could arise in many developing in the same way. However, the gas giants, like Jupiter and Saturn, would not exist, and the lack of such planets could spell doom for the earth, because in this case it is all too often subjected to the effects of the asteroid.

9. What would be, if the first animals emerged from the ocean to the land, to possess six legs, instead of four?



Four limbs dominate the higher animals, and it goes back to the time when the fins had to evolve as landfall. But the animals could have fins and six, in this case, as scientists believe, life would be to develop "very close" to the ground, and large, intelligent animals, may never have existed.

10. What would be, if not extinct Neanderthals?



Neanderthals might have survived until the present time, then they may well say, would think and act as we do. But experts say that much more likely to assimilation, that is, there would be interbreeding with humans, which has led to the creation of hybrid species.

11. What would happen if the magnetic poles are reversed?



The question is not if it happened and when it happened, because in the history of the Earth is already happening. This happens when the iron atoms in the liquid outer core is gradually changing its direction for several thousand years.

12. What would happen if the forces that shape molecules would be twice as stronger or weaker?



The molecules are formed when protons from adjacent atoms "share" electrons. If the electromagnetic force, which is dependent on these bonds would have been different, the universe might have been deprived of life, and even the stars and planets. The attraction between the positively charged protons and negatively charged electrons clearly set, allowing atoms to form into larger biomolecules.

13. What would happen if there were only one type of food?



There is no food, which would contain everything a person needs. If there is only one piece of fruit or vegetables, or grain, it will lead to multiple organ failure. Eating meat only cause your body to start a "chew" their own muscles, if there is only the fruit, then you develop scurvy. Thus, the monotonous diet in any case, it is the road to death.

14. What would happen if the sun was two times less in size?



The sun would be more red and less hot. The area around it, which would have been suitable for life would be much smaller, with our Earth not be included in this range.

15. What would happen if you had to shoot a gun in space?



The weapon can fire in space, which forms the basis of occurrence of all kinds of absurd scenarios. If you are in a vacuum between galaxies, then pressing the trigger, the bullet will move in space literally forever. If you shoot while in the solar system, then pulled a bullet to the Sun, or to one of the giant planets. And if you shoot toward the horizon, standing on top of the lunar mountains, theoretically, you shoot yourself in the back.
