What is Space Time?

Space-Time is a theory on how space and time interact.

This type of space is known as 3+1 space, due to the fact that there are three dimensions of space and one dimension of time.

Who Developed the Theory of Space-Time? Albert Einstein created the theory of

the space-time in his theory of relativity, which was one of his most pivotal theories.

It is now widely accepted as scientific fact.

Einstein based it on Euclidian Space, an old, ancient Greek mathematical formula.

What does it all mean?

It simply means that large objects generate a great gravitational field bend space, and smaller objects orbit around the bent space.

What about an example?

Imagine you have a round sink. If you roll an object into the sink, it will

essentially orbit the bottom of the sink, until it eventually falls into the bottom.

This is an example of the Space Time Continuum, because the bottom of the sink is acting as a gravity source, and the object you rolled is acting as an object being pulled by that gravity source.

Time Travel

It is believed that it is possible for someone to move back and forth through time.

This process is called Time Travel. Little is known about Time Travel,

however, we are getting closer to unlocking it’s secrets.

Problems with Time Travel There are many problems associated

with Time travel that make many prominent scientists discredit it. Paradoxes Corrupting of the timeline of Earth Little evidence to support its existence Materials needed to create a device able

to transport people through time are exotic and not found on Earth in ready amounts

Grandfather Paradox

The Grandfather Paradox is one of the more well known time paradoxes. It states that if you go back in time, and

kill your grandfather, you should not exist. But, if you do not exist, you never had a chance to kill your grandfather, which means you would exist. But if the timeline is constant, you would then kill your grandfather again, and the process would repeat.

Time Corruption

If someone went back in time, it is proposed that anything he did to change the timeline would result in a butterfly effect. A butterfly effect is an effect which

ripples through space and time, altering time forever as each minute passes by. The more the time traveler tries to change the time-line, the more corrupt the timeline becomes.

Multiple Universe Theory

One theory that gets around the Time Corruption paradox is the theory that states that there are an infinite amount of universes. If you killed your grandfather in this type

of timeline, you would not corrupt the timeline you live in, instead, you would create a new timeline diverging from the main one you lived in.

Ontological Paradox

This paradox states that if you go back in time to try and stop an action you could possibly be the cause of the action you were trying to stop. For example, if you went back in time to

stop a war, you might accidentally do an action that would begin the war you were trying to start. You would be the cause of the war.

Space-Time Travel

Space-Time Travel is different from normal Time travel. Normal Time travel transports you to the exact

same geologic point as you started. If you went back in time in San Francisco, you would

arrive in the place San Francisco would be founded on. Space-Time Travel says that you would travel

through both space and time, and you would arrive at the exact position of space that you were in when you started. If you went back in time in San Francisco 2000 years,

you would not be on planet Earth, you would be in space.
