10 Facts About Physics


According to the author of We Need to Talk About Kevin, Marcus Crown, the following 10 unique facts about the science of physics is

1. Future events can affect events in the past.
Peculiarities of the quantum world is documented. But it's more strange oddity. According to the experimental physicist John Wheeler and others in 2007, changes in the particles present in the particles can change the past.

2. Most of the universe is missing
There may be more than 100 billion galaxies in the cosmos. Each galaxy has 10 million stars. Our sun has billions and billions of tons of weight. This material is visible matter in the universe.
Other material called 'dark matter'. This material still need an explanation, and it seems this material universe is expanding.

3. Objects can move faster than light.
The speed of light is constant in a vacuum is 300 thousand km / sec, and the light does not always pass through a vacuum. In water, the photon moves a third of the initial velocity. In nuclear reactors, some particles are forced to move in high speed even faster than light.

4. If the sun is made of bananas.
Hot sun because extraordinary weight, about billions and billions of tons and make it into the core of the colossal pressure. Pressure raises the temperature. If the sun is made of bananas, it would weigh billions of tons and has the same effect as the sun.

5. All materials maker of the human race to enter the sugar box.
Atom is 99.9999999999999999% empty space. If all the atoms are forced together and eliminate the space in between like a box of sugar, then the mass is about 10 times the mass of men live. This is similar to what occurs in neutron stars, supernova relic super-dense mass.

6. Fundamental explanation of the universe did not include past, present or future
According to the theory of relativity, there is no such thing as the present or the future or the past. Time frame is very relative. Our time together because we are moving at the same speed. If we move at different speeds, we will discover that we age faster.

7. Particles can affect the other side of the universe in an instant
When an electron meets antimatter twin, both will be destroyed in a flash of energy and two photons will be flying from the blast.
Twinning it will start spinning in the opposite direction, and instantly a twin on the other side of the universe also rotates.

8. The faster moving, more severe
If you run fast, you will gain weight. Not permanently, but just to add a little weight. According to the theory of relativity, mass and energy are the same. The more energy expended, the heavier mass.

9. There is an infinite amount of time writing and reading
According to the standard cosmological model today, the number of hosts that can be calculated even boundless as the scum. However, a limited number of possible historical events occurred as well as the number is limited.

10. Black holes are not black
The black hole is very dark, but not black. They shine and give a little light spectrum, including the visible light.
