Graduate Create Matter: A Puzzling Mystery
This has puzzled me for a very long time. I know the theory that the universe was created from a big bang, but this means that all the matter in the universe existed in a different form before that. Be it gas or some other weird substance, it still existed. So how can all this substance appear... -

Undergrad Needle which is almost touching a pane of glass
I didn't say it cannot be done, I said I found it difficult to understand the measurement. A.T, thanks for your post. I think you have hit the nail on the head with the comment about numbers and maths just being used by us humans. I think my problem is trying to understand the very complex time... -

Undergrad Needle which is almost touching a pane of glass
Thanks for the replies guys. I have been to Zeno's Paradox and it is indeed the same as my problem. I do understand that if I divided any space down infinitely it would still be the same size, and also understand that I must be seeing the issue slightly askew. I just find the initial first... -

Undergrad Needle which is almost touching a pane of glass
I am a little confused by movement. It is difficult to explain, but here goes. Say I have a needle which is almost touching a pane of glass, so close if fact that the smallest movement toward the pane would result in the needle touching it. My confusion is, if the needle has to move to touch the... -

Graduate Can the Future Influence the Past in Quantum Measurements?
DrChinese, thanks for the links. Although to be honest I was a little overwhelmed by the mathematics. Could I ask your opinion as to whether the future measurement actually does affect the past in such a case? Could it be possible that our conscious and sub conscious minds actually give us a...- kkapalk

Graduate Can the Future Influence the Past in Quantum Measurements?
Thanks for the reply Karl. Basically then, the photon or electron takes an infinite amount of routes to its destination and when we decide to measure the outcome only one of the 'choices' becomes reality and the others become non existent. So to simplify things the photon took routes one and...- kkapalk

Graduate Can the Future Influence the Past in Quantum Measurements?
Thanks for the replies, and the place in the book is under the chapter, The Contingency of History. Starting on page 186. Kev.- kkapalk

Graduate Can the Future Influence the Past in Quantum Measurements?
Just thought I would get a couple of opinions from you guys on something I find truly amazing. In Brian Greene's Fabric of the Cosmos he explains how the delayed quantum measurement experiment works. A single photon has already passed through a beam splitter and made the 'choice' of whether...- kkapalk

Graduate Is Time an Illusion? Opinions on Brian Greene's 'Fabric of the Cosmos
I would just like to thank all who have replied to my post, especially egor and gto as theirs were particularly helpful. Incidentally I have just read Zeno's paradox and the chapter about crossing the room, having to move ever smaller amounts to actually get there is something that has always...- kkapalk

Graduate Is Time an Illusion? Opinions on Brian Greene's 'Fabric of the Cosmos
Atty, I did not say it does. That was just Greene's theory. I found it hard to understand too. But being as he is a well respected scientist surely his idea is worth looking at and commenting on.- kkapalk

Graduate Is Time an Illusion? Opinions on Brian Greene's 'Fabric of the Cosmos
Why would there be a problem with interpretation? I do not have the book at the moment as I have just lent it out, but basically he states that all events in time do exist because if someone many millions of miles away who was on the same time frame as us suddenly got up and walked in a...- kkapalk

Graduate Is Time an Illusion? Opinions on Brian Greene's 'Fabric of the Cosmos
I would just like a couple of opinions on a subject I read in Brian Greene's Fabric of the Cosmos. He states that all of time exists. Every event that has happened or will ever happen exists in its own time line. For instance while I write this at the age of forty two the event when I take my...- kkapalk

Undergrad How Do Electrons Create an Interference Pattern in the Double Slit Experiment?
Thanks for all the useful replies. I am going to study the subject in more detail as it truly fascinates me. Thanks again for the great input, Kev.- kkapalk

Undergrad How Do Electrons Create an Interference Pattern in the Double Slit Experiment?
Thanks for the reply, much appreciated. Could you also answer this for me? Why does the pattern not appear with larger objects? Is the make up of the particle too complex, with too many (atoms?) jostling around? Also, when we observe what happens we collapse the probability wave. Is this because...- kkapalk
