Short Story of Moon Landing 1969. ( was it conspiracy, theories.)

 Men On The Moon:

🌕  On 20 July 1969, Neil Armstrong became the first person to walk on the Surface of the moon. He was joined by Buzz Aldrin. A third astronaut, Mike Collins, remained in orbit with the command and service modules.

🌕  What was it Like:

                                     Buzz Aldrin described the moon's Surface as like nothing on Earth. He said it consists of a fine, talcum - powder - like dust, strewn with pebbles and rocks.

                                     Why is there no blue sky on the moon?   — Because the Moon has no atmosphere.

🌕   What did they do there: 

                                        Armstrong and Aldrin spent almost 22 hours on the moon. About 2.5 hours of this was spent outside the Eagle, collecting rock and soil samples, setting up experiments, and taking pictures.

The Lunar module was nicknamed as the Eagle.

🌕   How did they talk ? 

                                      There's no air in space, so sound has nothing to travel through. Lunar astronauts use radio equipment in their helmets.

🌕    Here comes Earth: 

                                 Instead of the moon rising, the astronaut saw Earth rising over the moon's horizon — it looked four times bigger than the moon looks from Earth.

🌕    We have Transport  !

                                    Three later Apollo missions each carried a small electric car, a lunar rover, which allowed the astronauts to explore away from the lander. These were left on the moon when the astronaut left.

Transport over one lunar rover reached a top speed of 22km/h (13.5 mph). 

🌕    Splashdown to Earth:

                                      The astronaut returned to Earth in the Apollo 11 command module. This fell through the atmosphere and landed in the Pacific Ocean. A ringed float helped to keep it stable.

                                             Sounds that so weird :  The lunar module computer on Apollo 11 had just 71 K of memory. Some calculators can now store more than 500 K of memory.

The Short Story Of Atomic Bomb with Oppenheimer. { Manhattan Project }

 💣  Scientist of the Manhattan Project complete the Atomic Bomb destined to end World War - II :     

In the Movie Oppenheimer shows the Atomic Bomb Explosion.
 ( By Director "Christopher Nolan" ).   

💣  During World War the United States used an unprecedented $2 billion to feed an ultra-secret research and development program, the outcome of which would alter the relationships of nations forever Known as the Manhattan Project, it was the search by the United States and her closest allies to create a practical atomic bomb: a single device capable of mass destruction, the threat of which alone could be powerful enough to end the war.

💣  The motivation was simple. Scientists escaping the Nazi regime had revealed that research in Germany had confirmed the theoretical viability of atomic bombs in 1939, in support of their fears that the Nazis might now be developing such a weapon, Albert Einstein and others wrote to President Franklin D. Roosevelt (FDR) warning of the need for atomic research By 1941 FDR had authorized formal, coordinated scientific research into such a device. Among those whose efforts would ultimately unleash the power of the atom was Robert Oppenheimer (1904-1967), who was appointed the project's scientific director in 1942. Under his direction the famous laboratories at Los Alamos would be constructed and the scientific team assembled.

💣  An atomic bomb initiates a nuclear chain reaction, thereby releasing truly vast amounts of energy. An initial problem was the production of enough "enriched" uranium to sustain such a reaction Instrumental in the solution was Italian physicist " Enrico Fermi "in a former squash court under Chicago University, he and other scientists created the first ever controlled, self-sustaining nuclear chain reaction. The project ultimately created the first, man-made nuclear explosion, which Oppenheimer called " Trinity ", at Alamagordo, New Mexico, on July 16, 1945...

The Black Hole Explosions

The lower the mass of the black hole, the higher its temperature is. So as the black hole loses mass, its temperature and rate of emission increase. It therefore loses mass more quickly. What happens when the mass of the black hole eventually becomes extremely small is not quite clear. The most reasonable guess is that it would disappear completely in a tremendous final burst of emission, equivalent to the explosion of millions of Thermonuclear bombs.

A black hole with a mass a few times that of the sun would have a temperature of only one ten-millionth of a degree above absolute zero. This is much less than the temperature of the microwave radiation that fills the universe, about 2.7 degrees above absolute zero — so such black holes would give off less than they absorb, though even that would be very little. If the universe is destined to go on expanding forever, the temperature of the microwave radiation will eventually decrease to less than that of such a black hole. 

 The black hole will then absorb less than it emits and will begin to lose mass. But, even then its temperature is so low that it would take about 10⁶⁶ years to evaporate completely. This is much longer than the age of the universe, which is only about 10¹⁰ years.

There might be primordial black holes with a very much smaller mass that were made by the collapse of irregularities in the very early stages of the universe. Such black holes would have a much higher temperature and would be emitting radiation at a much greater rate. A primordial black hole with an initial mass of a thousand million ton would have a lifetime roughly equal to the age the universe. Primordial black holes with initial masses less than this figure would already have completely evaporated. However, those with slightly greater masses would still be emitting radiation in the form of X rays and gamma rays. These are like waves of light, but with a much shorter wavelength. Such black holes hardly deserve the epithet black. They really are white hot, and are emitting energy at the rate of about ten thousand megawatts.

 

One such black hole could run ten large power stations, if only we could harness its output. This would be rather difficult, however. 

The black hole would have the mass of a mountain compressed into the size of the nucleus of an atom. If you had one of these black holes on the surface of the Earth, there would be no way to stop it falling through the floor to the center of the Earth. It would oscillate through the Earth and back, until eventually it settled down at the center. So the only place to put such a black hole, in which one might use the energy that it emitted, would be in orbit the Earth would be to attract it there by towing a large mass in front of it, rather like a grass in front of a horse. This does not sound like a very practical proposition, at least not in the immediate future...

We can calculate the temperature of black hole, By using this equation:
