What really exists?

“Do we create what we observe through the act of our observations?” This question asked by Joshua Roebke is probably one of the most complicated questions known to man. It is also highly philosophical. The idea that things do not exist without us has the possibly to shake the foundations o every piece of standing knowledge that we have. Quantum Mechanics is the subject which has the possibility to answer this question however. An Irish Clergyman by the name of George Berekely has his own take on it. From what I read about Quantum Mechanics in this article it would seem evident that he does agree with this subject. He was an idealist and believed heavily in the idea that things only existed if and when they passed through our senses, meaning if we were able to perceive them or not. Quantum Mechanics attempts to prove this idea correct because in order for it to exist we must prove that objects do not previously exist unless we perceive them. The ideas of Quantum Mechanics are derived from Berkeley's work and for the most part confuses me because it takes what George Berkeley had theorized and develops into far greater detail.
One strength that I find in Roebke's theory is the idea that every electron when affected will have an effect on another electron no matter how far away. This idea can be taken as a ripple effect. Think of throwing a rock into a pond and when it splashes it makes ripples in the water. These ripples do not stop, they just continue to get smaller and smaller until we can no longer see them. My guess is that eventually all of the water in the pond will be effected because atoms and electrons are constantly in motion and by affecting one we could inadvertently affect them all.
