Time, Space, Energy (and Anti-energy?), and Wormholes

I am still not sure why negative energy should only work one way in spite of the analogy with money lending . . . the interest why not interest both ways every action an = an opposite one? I mean I can earn interest not just pay it (well maybe I can, a little bit; some folks earn more than they pay out I am sure).

Energy by the way is related to mass which is related to how much matter there is and how much anti-matter (matter which has theoretically a negative mass). Wherever there is mass there is stored energy.

I do believe simply that if you leave Earth and race to Alpha centauri faster than the speed of light (so that you get there before your image from there gets back), we lose track of you for sure (if you race at the speed of light, I think you look like a ray sort of -- we see a continuum of your light bouncing back from when you left to the point where you are I think; I have had a cat who looked like this when she decided to hop out of the bushes and into the door -- she had to move fast or I'd see her; the article says your faster-than-light starship won't look like a ray but what about a speed-of-light one? one travelling at the speed of light, relative to you-- if it's travelling from you or toward you, I mean in one of these cases, yeah, I think it would look like a ray). You are still you; time may be warped differently on alpha centauri than on earth and that's what affects your age when you stop; the age you'd be on alpha centauri, perhaps, temporarily, while you are there.

Here's more on outrunning the speed of light and hence the curvature of space-time (from the article):

"special relativity says that you cannot outrun a light signal in a fair race in which you and the signal follow the same route. When space-time is warped, it might be possible to beat a light signal by taking a different route, a shortcut."

That's as far as I get with the curvature of space time. Since I'm talking about a round trip, you come back to Earth. While you're spinning toward it at a different speed than Earth (speed is relative to where we are; you can't measure absolute speed, only speed relative to something), I dunno but when you stop, if you were gone 2 years for the round trip, you are going to be exactly 2 years older. That's all in my opinion. Though you've travelled at 4 times the speed of light including your stopping time in the measure, I don't see how you can be younger than you are at this point. And actually I am not sure that the effect of gs and other things would not age you (but actually it's in low not high gravity that bones become brittle of course). Thus, as below, "I'm from Missouri." (see http://www.sos.mo.gov/archives/history/slogan.asp on Missouri; of course I was not born in Missouri, but I've been through Missouri once or twice, saw the Mississippi, where Huck Finn and Jim supposedly went down it and missed their turn off to free Illinois.)

I do believe some "black holes" we think of as points in space actually, because light can't get out (gravity caused by black holes bends light and even prevents some from escaping; hence regardless of temperature, these appear black), hide other parts of our universe which we can't see and we can't even know all the mass that's there; only that close enough to affect the g field around the "hole" (these are worm holes, or actually wormholes I guess; the gravitational field of these, for those who have not looked into these before, does not let light get out of the wormhole or black hole as the case may be). Other black holes are no doubt really "points in space," or small areas, where we can see what surrounds them, except that light is bent. In theory perhaps these can have singularities in the middle (points of 0 volume, but mass, yes, hence of course the density, mass divided by volume, goes to infinity). What happens to time in the singularity? I dunno, but as for space you obviously cannot move in space freely in such a point (and gravity won't let you escape); you are at the mercy of where the singularity takes you so space in a singularity is a bit like time on Earth -- but is time like space on earth? I mean, can you move in it? (I am sure by the time I am inside a singularity I can do nothing.)

In other words, "I am from Missouri." I have not read enough into this (I need to for an article I am writing I guess), but some of this stuff sounds well unbelievable.

Just a definition here; the event horizon is the point at which, in the observer's view of things (everything seen in the universe is seen relative to an observer), no light can be seen getting out (because it is warped by a gravity field different from what the observer experiences).

Another definition you may need here; because it's the distance at which things that look like waves look like particles it's something to think about. (Do all waves look like particles here? What about gravity waves? Maybe there is a point at which these too look like particles, but we've not measured it. Whatever, if anyone builds a wormhole as they are not going to do anytime soon of course, I hope the negative energy is compressed into a small enough space that it all works out). Another question on the Planck length: I suppose we really cannot measure anything small than it. So is it or 0 the diameter at a singularity? If it is, then does density still go to infinity? The Planck length is related to the planck constant, the gravitational constant, and the speed of light (see http://en.wikipedia.org/wiki/Planck_length).

And these are only created by negative energy? Well what I read years back was that a magnetic field could be created by say a simple solenoid, any electric charge has a magnetic field associated with it (electons attract protons, right? thus if you touch a light bulb -- I have a burn scar across my arm to prove this point -- you can in some instances stick to it and not be able to escape easily -- I had to break the bulb at which point I fell to the floor, across the room of course; this was when I was young and jogged I dunno maybe 15 to 20 miles daily; I recall that when I was burned I had just run 15 or 20 something miles; it would stop my heart today to encounter that much electricity I am sure). To get back to the point of this, so once you have a magnetic field, it can draw matter through it at different speeds, speeds controlled by the magnet.

But apparently with just a magnetic field you have something like gravity and the wormhole collapses (or I dunno or don't understand this point). So then you need negative energy here they say.

Since no one is building wormholes of any size in any hurry, the real application of wormholes and negative energy may be in energy. Maybe.
