Hi my friend, I revised this essay for you. Some parts I took out because I could not understand. Feel free to message me with any questions or if you need more help! :)
How deep is universe?
What is speed of light? Can we time travel?
These questions have been formulated by humans around the
world. One of mankind’s defining characteristics is an insatiable desire for
information which drives us to a constantly travel, research, and learn. One
individual who displays this quality is Albert Einstein.
One of his most famous works is the Theory of Relativity
which establishes that the perception of time is relative. Many others
investigated this phenomenon using various experiments. In
one such experiment, a scientist placed a person
wearing a watch in a rocket traveling at 300,000 kilometers per second. Another
person stood still in a different spot with a watch in hand. The watch of the
person in the rocket was two hours ahead of the other person’s watch. The scientist
concluded that time goes faster when an object is traveling near light speed. <o:p></o:p>
Another experiment involved a set of twins, one of them
worked on spaceships for many years while her sister stayed in the earth. The
experiment surprised both the scientist and the twin. The twin who traveled to
space was only twenty years old; however, she had already developed osteoporosis
due to radiation exposure. <o:p></o:p>
Lastly, Euclid questioned if space is curved. The
answer to his question came from the simple fact
that if a laser is pointed towards space there are only two possibilities: the
laser will touch the “curve” of space and return to earth or the laser will
never come back. <o:p></o:p>
There are many other examples throughout the life of Einstein which demonstrate
humankind’s quest to study profound questions.<o:p></o:p>
