Because its density is so high, neutrons spin in the same way that electrons do so must obey the Pauli Exclusion Principle. 6. A pulsar does not pulse, it emits beams of radiation that sweep around the sky as the neutron star rotates, and astronomers detect pulses when they sweep over the Earth. 11. Sometimes in binary systems, mass flows into a hot accretion disk around the neutron star and causes the emission of x rays.
The arrangement of particles in an atom Protons and neutrons make up the main, dense, central nucleus in the centre of the atom. This is surrounded by electrons “orbiting” the main nucleus. The electron are in shells depending on their energy levels, as the most energetic are on the outer shells, because they need more energy to travel around a bigger “orbit” of the nucleus. These shells are full when a certain amount of atoms are in the shell; 2 in the first shell, 8 in the next shell, 8 in the third shell and so on. When the shells are full, the atom is unreactive.

More than a century later, Einstein, came up with the theory of relativity. It states that nothing can travel faster than the speed of light, therefore, no matter can escape it. (O.N.L. 47-56) Karl Schwarzschild, in 1917 used Einstein theory to calculate that if a star of a curtain mass was to shrink pasted the critical point it would become a Black Hole. The theory is named in his honor, the Schwarzschild radius.
It is called Newtonian, because it began from the Newtonian discovery of the laws of gravity and world motion. Newton’s law was composed of three laws. And form a clear description of all possible motions, where as Ptolemy was the baseline and gave the first guideline about the universe for almost 1500 years. Newton’s universe was very clear and concise. It told us the only way to change the motion of an object it to apply a force.

Have you ever looked into the night sky every day for a month to notice that Mars has moved from west to east to west again, that’s retrograde motion. Retrograde motion is a natural occurrence that appears to happen to other planets in our solar system from earth. Retrograde motion is what happens when a planet (we will use Mars as an example) looks as if it is reversing. This occurs when the Earth passes the planet. Direct motion and retrograde motion both occur with Mars, direct motion is when the planet seems to be going forward, and retrograde is when it seems to be going backwards.
Using mathematics, he showed that a single force keeps the planets in their orbit around the sun. He called this force gravity and then created Newton’s law of Motion. Law one states that an object at rest will remain at rest, and an object in motion will remain in motion, at a constant speed unless or until outside forces act upon it .Law two states that the net force acting upon an object is a product of its mass multiplied by its acceleration. Law three states that when one object exerts a force on another, the second object exerts on the first a force equal in magnitude but opposite in
With the exception of gravity, electromagnetic phenomena as described by quantum electrodynamics account for almost all physical phenomena observable to the human senses, including light and other electromagnetic radiation, all of chemistry, most of mechanics (excepting gravitation), and, of course, magnetism and electricity. Electromagnetic fields are time varying fields containing both electric fields and magnetic that feed upon each other even in a vacuum. A vacuum is defined as a void of medium. These field lines actually detatch themselves from the source and can exist on
