ALIENS
liens are actually real because apparently
aliens lives at Mars. Here are some short videos
on YouTube about do aliens really exist

iQ
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.
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.
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.
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.
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.
Space Travel
The space age began in 1957 when the Soviet Union launched
Sputnik Apollo 11 blasted off on July 16, 1969. 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.
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.
