# fields and energy

 Posts: 4,198 Add as FriendChallenge to a DebateSend a Message 4/16/2015 4:21:53 PMPosted: 1 year ago"There's one field for each type of particle. So one field for all photons in the universe, one field for all electrons, and so on. And these fields exist everywhere.To "extract" a particle from a field, you need to give the field energy. If you give it enough energy, the field will go to a higher energy state. These states are what we interpret as particles."I read this and I have a few questions.1.) can a field exist without a particle2.) can a field exist without energy3.) Is the rest of the paragraph even accurateYou are what you do when it counts ...and it always counts "Your mother still exist and created you, despite her nasty spaghetti" Fatihah

Is the rest of the paragraph even accurateThere are various types of fields, but they are essentially a mathematical constructs to show positions in space from some sort of a source. For example, between the earth and moon, there is a gravitational field, one for the moon and one for the earth, each one dissipates in strength the further it is from the source. In this way, we can plot any given position within these fields and calculate the strength of gravity.Marrying a 6 year old and waiting until she reaches puberty and maturity before having consensual sex is better than walking up to a stranger in a bar and proceeding to have relations with no valid proof of the intent of the person.

I found the questions interesting, but my last foray into fields was around 30 years ago so I deferred attempting an answer in the hope that someone with more current knowledge might be able to contribute.

Is the rest of the paragraph even accurateIt may help to remember that 'field' is also a metaphor. Way back when, my physics teacher told us "When it comes to quantum physics, what we have are equations. People try to make mental images of the equations, but they all fail in one way or another. The subatomic world is simply not like anything we've ever experienced in the macroscopic world". So fields and candy machines, same as the orbits or clouds of my day - don't try to understand them. If they help you visualize the equations, that is, the known behavior of the subatomic world, fine, but if not, ignore them.This space for rent.
