In the double slit experiment, there is interference between the fired particles when both slits are opened. Yet, when an observer checks to see what's actually going on by looking at the slits as the particles pass through them, the interference disappears. In other words, the particles act...
That was SO helpful. I'll read Feynman's book and look into this further. Please, if anyone could give me any more information, even if it does not pertain to the question, that would be wonderful. This is changing the way I think...
As far as I know however, there doesn't need to be anything before the Big Bang, because time itself was not present, and as such, nothing would require a beginning or an end--both qualities that are attributed to our fourth dimension.
The universe is mathematically approaching the concept of infinity, but is, and will never be, itself infinite. Nothing quantitative in the known universe can be infinite.
I cannot believe this. I am actually also reading The Grand Design on my Kindle App on my PC as well, and I just finished reading all of Chapter Four. Quantum physics is a new endeavor to myself as well, and I had the same questions that you have. According to the author, it is the act of...
Stephen Hawking gave me a clear timeline of the universe, from the expansion of the singularity to its current (and still expanding) state. I understand that the singularity was one point of infinite density (correct me if I'm wrong). My question is, what had happened before the singularity...
How does Feynman "Sum Over Histories" make sense?
Hi. I am new to Quantum Physics and this forum as well. I was reading The Grand Design, by Stephen Hawking, and came upon the "Alternative Histories" theory in Quantum Mechanics.
My questions are:
1.) How is it possible that a particle can...
