3 ALIENS. BLACK HOLES. TIME TRAVEL USING WORM HOLES. BIG BANG THEORY. SPACE TRAVEL. MAN ON THE MOON.

4 ALIENS Aliens are actually real because apparently aliens lives at Mars. Here are some short videos on YouTube about do aliens really exist Scientist believes that aliens do exist UFO researchers use the term 'greys' to describe alien visitor with an oval shaped head and large eyes - similar to the depiction shown in the film Close Encounters of the Third Kind.

5 Black Holes A black hole is a mathematically defined region of space time exhibiting such a strong gravitational pull that no particle or electromagnetic radiation can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

6 Black Holes A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.

7 Time Travel using worm holes
Since the 1930’s, physicists have speculated about the existence of "wormholes" in the fabric of space. Wormholes are hypothetical areas of warped space time with great energy that can create tunnels through space time. if traversable would allow a traveller to quickly move through great distances in space and also travel through time. The difficulty lies in keeping the wormhole open while the traveller makes his journey: If the opening snaps shut, he will never survive to emerge at the other end. For years, scientists believed that the transit was physically impossible. But recent research, especially by the U.S. physicist Kip Thorne, suggests that it could be done using exotic materials capable of withstanding the immense forces involved. Even then, the time machine would be of limited use – for example, you could not return to a time before the wormhole was created. Using wormhole technology would also require a society so technologically advanced that it could master and exploit the energy within black holes.

8 The Big Bang Theory The Big Bang theory describes how the Universe began in a rapid expansion about 13.7 billion years ago and has evolved since that time. It is thought that all of space was created in this first moment. Since the 1940s, when the modern form of the theory took shape, scientists have detected radiation from the early Universe with radio telescopes and satellites and named it cosmic microwave background radiation (CMB). The CMB, which is formed of microwaves and radio waves, is considered important evidence in support of the Big Bang because it matches theorists' predictions. Big Bang Theory - The Premise The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something: our universe. The big bang theory is an effort to explain what happened during and after that moment.

9 Space Travel The space age began in 1957 when the Soviet Union launched Sputnik Apollo 11 blasted off on July 16, Aboard the spacecraft were Neil Armstrong, Edwin (Buzz) Aldrin, and Michael Collins. Four days later, Armstrong and Aldrin landed the Lunar Module Eagle on the Moon. They moonwalked for three hours. They did experiments and picked up samples of Moon dirt and rocks. Collins remained in orbit doing experiments and taking photographs. The astronauts planted an American flag in the lunar dirt. Eagle was on the Moon's surface for less than one day before it blasted off and rejoined the Command Module for the trip back to Earth. Apollo 11 splashed down in the Pacific Ocean where it was picked up by a Navy ship.1.

10 Man On The Moon Neil Armstrong was the first man on the moon. Here is a picture of Neil Armstrong who walked on the moon. This the man who was the 1st man on the moon. Neil Alden Armstrong was an American astronaut and the first person to walk on the Moon. He was also an aerospace engineer, naval aviator, test pilot, and university professor. Neil Armstrong was the first person to walk on the moon. He was an astronaut. He flew on two space missions. One was Apollo 11. That mission landed on the moon. He was also an engineer, a pilot and a college professor.
