What's the total energy of everything that exists?

[beavis]

By definition, there can only be one universe. Multiverse is a crappy way to describe sections of the universe. The sections are not as separated as you think. The title of this thread contains "everything that exists" instead of "universe" to avoid that confusion.

Khuli follower, that's the same thing that I said. Wormholes are communication channels between two points in any space time realm, so it can be between two dimensions(ie Universes) or it might be unidimensional. Thus it's the same thing that I said, just that I gave the specific method and reason why such things happen.

Yes, it's true that realising how these universes are seperated is difficult. We just say them Universes to avoid confusion. If we say that all these interconnections between the universes is given the name Hierarchy(Hmmm... neat name). Who knows if there are more than one hierarchy and how the other Hierarchies are interconnected and this will again go on and on.

I apologize Vikram I guess I was just thinking about something else at the time.  You understand what I am talking about.  Once again I apologize.  Hope to speak to you again soon.

Good fortune and good training my friend...

"Hey Beavis,
Let's face it there was nothing to start with, but if that nothing was somewhere it was localised at a mathematical point, therefore there was an infinite uncertainty in how much energy there was (according to Heisenberg's uncertainty principle). I know you know what I'm on about 'cos I read one of your previous quantum physics posts! Someday the universe will work it out."

In Heisenberg's uncertainty principle it basically states that one cannot know the speed and position of a given atom without sacrificing either one or the other.  Also, there must not be an infinite amount of energy because it is just nature's behavior to achieve equilibrium. And if you end up with an infinite answer, you know you've done something wrong.  

My take on the total energy of the universe agrees with everyone else that says it = 0.  For every particle there is the opposite,  aka antimatter.  

The multiverse theory isn't such a bad "way to describe sections of the universe" at all.  In fact it's pretty intuitive.  I'll take an example from the book I am currently reading :

Say you are a mile away from a suspended water hose that stretches between two houses.  Now, in your perspective you just see a one dimensional plain, which has only two directions, left and right.  Lets now say you took a pair of binoculars and noticed an ant on the hose.  You can now say it is a 2-d plain.  The ant can move up and down, left and right.  Now, Kaluza, (a man who came up with this idea), stated that there must be more dimensions than meets the eye.  In this everyday dimension we can only see extension, x,y, and z axes.  But Kaluza proposed that there must be "curled up" dimensions within the spacial dimension we live in, like the hose example.  Within each point in the space, there is the x axis, y axis and z axis, but Kaluza states there there is one more that wraps around itself, like a the circumference of the hose.  But these dimensions are so small that even what we have today cannot detect, and it was calculated to be around a Planck length.

So we see, that our fabric of space can be seen as a 3-d carpet looked at from a far distance, but as we look closer, we notice that the carpet is actually interwoven, giving it an extra spacial dimension, 4-d.

I dont know how to answer that question but if you pm me ill give you the name of this book that has the weight of the the world and might have that.Its supposively authored by celestial beings.

Is it negative, zero, or positive?

Mass, energy, and space can all be converted to energy, according to relativistic physics.

I read that science says the total is positive, but I dont believe them because they havent measured astral and probably many other places farther away. They can only see 15 billion lightyears away.

This question also includes the energy in all times, because all time exists simultaneously.

If the average energy of our local area of space (15 billion lightyears) was zero, the opposite energies would have destroyed each other (destructive wave interference). Usually, an area gets an amount of negative and positive energy that is at least some different. The amount of energy left is their difference, and it will be mostly positive or mostly negative. That is probably what happened here, so we Assume it is all positive.

I suspect the total energy is zero.
