Is is possible to hack into the Universe?
Yes.

How do I hack into the Universe?
First achieve Enlightenment. This is the easiest thing not to do.

Help
Studying fine art will train your mind in objective thinking. It requires self discipline, you become your teacher.
Do not waste time on abstract art, it is just shapes with a catchy title, it won't help you, it is a Master/Servant relationship.
See things for what they are. Existence. Art.
Study ALL religions and concepts. See each one as Valuable, because they are based around the thoughts of great thinkers. See through the marketing gimmicks, get to the originators of the religions and study their philosophy. All great religious/spiritual leaders(initiators, not masters) have the same realisation. Find out what it is.

After Enlightenment you see clearly. Now All and Nothing flows through you. You see past, present and future as a single, infinite concept. Cause and Effect become one thing. In fact, everything becomes one thing, or no thing.

Test existence.
Create a cause and effect ripple. Do something unexpected. You must influence the Universe before you can divert the flow. Monitor the ripple as it moves away and back towards you. The ripple returns because it has encountered something - a concept - a materialisation.
By understanding the shapes of the ripples of materialisation you can map out the outlines of your existence through realisation.
Now you can create a cause and effect ripple with a predictable outcome. This takes practice, any normal person will fail 100 times before succeeding once.

Measuring Ripples of Cause and Effect
What are ripples? Events, noticeable reverberations in society, materialisations of concept. The closer you look the more you notice.

An experiment:
Notice someone walking on the street.
Walk up to them and say something innocent and positive to them.
Walk away.
Without being seen, notice how they change as the walk, notice how they influence their surroundings as they pass, how they influence others. How others now influence you.
Now notice someone walking on the street. Do you see them differently?

Thoughts are real
Beginner hackers will use the physical aspect of reality to influence the All. More advanced hackers realise that concepts have physical outcomings in the world.
The most advanced hackers notice that thoughts themselves influence the world.
WHY?
To explain this we must make a brief diversion.
Where were you before you were born? Where will you be after you die? Who are you? Not, "What does your body-shape do in the world?" but "Who is the being that is thinking now?"
and more importantly, who is the being listening to these thoughts?
Is it you? Is it God? Are you God? Is god You?
No, but you are getting warmer by asking.

What is the connecting point between your thoughts and your actions? If you think of moving something like an arm, why does the arm move? Is it your brain? Why does your brain know how to lift your arm? Self discovery? How does it know how to discover itself?
You will discover the answer when you look for the answer.

The question is the answer.
The answer to "What is the meaning of Life?" is "What is the meaning of Life?"
The answer is the question.
"What" is the meaning of Life. Life, as we understand it, is our bodies in this place. It's purpose is to exist, it is physical - a "what". It needs no other purpose. Only modern Western thought requires all things to have a purpose. Ancient Eastern thought sees the value in something in its existence.

When you discover the answer you realise that moving your arm is no different to moving your foot, or moving your shoe. Can you move your shoe without moving your foot? YES. It is the same thing. You are moving something with your mind.

This is potentiality. All things are possible. Knowing how to manifest actions in one's self requires self-awareness. Manifesting actions in some other object requires awareness of that object. Not Vision, or Feeling, or anything sensual of that object, but Awareness.
