1. What would happen if the Earth were twice?
If the diameter of the planet was 16,000 km, the mass would increase by a factor of 8, and the force of gravity would be twice as strong. All the plants and animals that exist today would have died under the weight of their body weight, and there would be a new species.
2. What would happen if the world there was another view similar to humans?
If the planet was inhabited by another, as technologically savvy kind of beings as people, then we would take place between the 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 did not?
If the asteroid fell to Earth, the dinosaurs, in all probability, would still be ruled by the planet. After all, the prevalence of dinosaurs on Earth — is out of the ordinary event. Researchers have suggested that instead of people there would be "dinozavroidy", which would possess a relatively large brain, began to develop in the latter appeared on the earth of dinosaurs.
4. What would happen if everyone in the world jumped at the same time?
If all people would gather together and simultaneously jumped, then it would make the earth move to the one-hundredth of the radius to the side, but after landing, the earth would return.
5. What would happen if the moon had never formed?
Huge tides generated by the moon, whose orbit was much closer to the Earth during its formation, washed "chemical" building blocks involved in the origin of life. Without it, there would be a life or living things have developed very different behaviors to cope with the six-hour day and extreme climate changes that would occur in a moonless Earth.
6. What would happen if humans were twice as intelligent?
In this case, according to experts, we would be more developed at the individual level would be healthier, look better and be less religious. Nevertheless, you still would be different from each other, and the society would be as contentious as it is now.
7. What would have happened if all the cats on Earth suddenly died?
Cats may seem ordinary, meaningless animals, but they are vital members of the global ecosystem. Thanks to the studies that examined the implications of the withdrawal from the territories cats small islands, we know that without them the Earth would be promptly captured rodents. Mice and rats, probably would have destroyed all stocks of grain, would spread a lot of diseases and would destroy the ground-nesting birds.
8. What would have happened if our solar system formed would be closer to the edge of the Milky Way?
Although on the edge of the galaxy there are only about a third of all the metallic elements, compared to the spot where we are, life could arise in many developing in the same way. However, gas giants like Jupiter and Saturn, could not exist, and the lack of such planets could mean the death of the Earth, because in that case it would have been too often exposed asteroids.
9. What would have happened if the first animals that were released from the ocean to the land, would have six limbs, not 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 and six fins, in this case, as scientists believe, life would develop "very close" to the ground, and large, intelligent animals may never exist.
10. What would have happened if it had not become extinct Neanderthals?
Neanderthals may have survived until the present day, then they may well say, would think and act as we do. But experts point out that it is much more likely to assimilation, that is, there would be cross with people, which led to the creation of hybrid species.
11. What would happen if the magnetic poles change places?
The question is not if it happens, and when it happened, because the history of the Earth is already happening. This occurs when the iron atoms in the liquid outer core is gradually changing its direction for a few thousand years.
12. What would happen if the forces that shape the molecule would be twice as strong or weak?
The molecules are formed when protons from the neighboring atoms "share" electrons. If the electromagnetic force, which determines these relationships would be 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 that enables atoms to form into larger biomolecules.
13. What would have happened if there was only one type of food?
There is no such food, which would include everything that a person needs. If there is only one fruit or vegetable, 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 a fruit, then you will develop scurvy. Thus, monotonous food in any way is the road to death.
14. What would happen if the sun were half 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 less, while our Earth is not included to this radius.
15. What would have happened if you had to shoot a gun in space?
Weapon can fire in space, which provides the basis of the appearance of all the absurd scenarios. If you are in a vacuum between galaxies, then pulled the trigger, the bullet will move in space literally forever. If you fire, while in the solar system, the bullet will be pulled or to the sun, or one of the giant planets. And if you go off toward the horizon, standing on the top of the lunar mountains, theoretically, you shoot yourself in the back.
