What people are saying here is just one interpretation of quatum physics. The question of the "observer effect" is more complicated than that.

Seems like quantum physics is the most bastardized theory from the physicist point of view. People use it to justify all kinds of metaphysical beliefs. That's not to say I disagree with anybody here, physics has many unanswered questions. People may believe what they believe regardless of what science says.
The developments in physics are interesting to me because of the implications it can have on my life. I do hope we get closer to answering the perennial questions, I'm having a hard time finding my purpose with some of these unanswered (possibly unanswerable) questions.
There are probably hundreds of physics/metaphysical topics out there, you could further reading into but here's a few.
String Theory/M Theory (seems the most popular yet unfalsified theory)
End of the Universe
Finite or Infinite Universe
Many Universes/Worlds or Multiverse
How can something come from nothing? Did that happen?
