Could We Find a Door To A Parallel Universe?

p1234 writes "Though no direct evidence for wormholes has been observed, this could be because they are disguised as black holes. Now Alexander Shatskiy of the Lebedev Physical Institute in Moscow, Russia, is suggesting a possible way to tell the two kinds of object apart. His idea assumes the existence of a bizarre substance called "phantom matter", which has been proposed to explain how wormholes might stay open. Phantom matter has negative energy and negative mass, so it creates a repulsive effect that prevents the wormhole closing. 'US expert Dr Lawrence Krauss, from Case Western Reserve University in Cleveland, Ohio, points out that the idea rests on untested assumptions. He told New Scientist magazine: "It is an interesting attempt to actually think of what a real signature for a wormhole would be, but it is more hypothetical than observational. Without any idea of what phantom matter is and its possible interactions with light, it is not clear one can provide a general argument."'"

this post being modded insightful bothers me, because it is actually a perfect example of having no insight into the situation.

1. Define the question
2. Gather information and resources (observe)
3. Form hypothesis
4. Perform experiment and collect data
5. Analyze data
6. Interpret data and draw conclusions that serve as a starting point for new hypothesis
7. Publish results
8. Retest (frequently done by other scientists)

taken from wikipedia those are the steps of the scientific method. I remember them from middle school, so I imagine most of this crowd should have been over them at some point. This article is a perfect example of step 3 in my opinion. step 2 is all of the already observed behavior of matter in the universe. here in step three we form a hypothesis about some detail that is unexplained or not understood. step 4, which these people have not gotten too yet, is to figure out a method to perform tests to prove or disprove their hypothesis and perform those tests. then they will analyze the results of their test, step 5. skipping over this step would leave them with no direction to take in their research, so they would probably never figure out anything.

Absolutely. I wish I could mod you up, but I've already posted in this discussion. :(

I think some people are quibbling with Step 1: Define the Question. Their complaint is that this is just a silly question that doesn't really matter (since we don't have proof that these things exist, why bother trying to figure out how they could exist...). I'm not of that mind, but clearly many people think that new theories must arise strictly from unexplained observations (I observed the apple fall down rather than up, but I have no theory to tell me why...). This is a rather limited view of science, IMHO (especially for phenomena we can't observe in a lab or nature). If scientists never are able to connect this theory to observation, it simply will fall into the dustbin of history. But that doesn't preclude it from being part of the scientific discussion until it is refuted conclusively.

......einstein started out with thought experiments.......

I was under the impression that experiments were real, not something imagined in some brain, even Einstein's brain.

Nobody has ever directly observed a back hole. Here is a different thought experiment:

Suppose it were technically possible to drill a hole clear through the Earth. If then a rock were dropped into the hole, would it not eventually come to rest, floating right in the center of the planet? Would that not mean that in the exact center there is no gravity to cause pressure on the material in the center either?

Would this canceling out of the gravity also then preclude enough pressure from happening to squeeze matter to anywhere near the density to eliminate all space between atomic constituents? Would this canceling of gravity be reversed if enough matter were piled together in one place? It seems to me, not, that in any sphere of matter of any mass, the gravitational pressure on the material in the center should always be zero. Would this not preclude the formation of a real physical object, a so called "black hole" as described in the purely mathematical constructs that postulate the real existence of such things? Of course if there are no real physical black holes, then there wouldn't be any real physical "worm holes" or any other kinds of "holes" either.

Does this canceling of pressure in the center of the sun mean that there isn't such a huge pressure there, even enough to allow atoms to fuse?

We know from real experiments and everyday experience, that heat always moves for the hotter place to the cooler place. Why is it then that we actually MEASURED that the outside of the sun, the corona is thousands of time hotter than than its surface? Why are sunspots, apparent holes in the surface of the sun, significantly cooler than the surrounding surface?

Could it be that the idea that atomic fusion with its requirement of million degree temperatures in the interior of the sun is just plain wrong? Maybe the sun is powered neither by an ancient wood campfire nor by a modern thermonuclear camp fire.

Maybe it is time to base science solely on experiments and observations, rather than fanciful math that has little if any semblance to reality as we can observe it. I think that real science, based on experiment and observation should be well separated from science fiction even if the fiction is very beautiful mathematically, or makes for intriguing and exciting movies.

Sqrt(Negative energy) = head hurts

[G4from128k (686170)]

IANAP, but most "energy" variables can be thought of as the square of some other physical properties (kinetic energy is related to velocity squared, electrical energy is related to voltage or current squared, etc.) So to get "negative energy", it would seem that we need imaginary (as in the number i = sqrt(-1) ) values of velocity, voltage, current, etc. So now my brain hurts (and the real physicists on slashdot can enjoy ripping me to shreds or educating me as is their wont)

Re:Sqrt(Negative energy) = head hurts

[Manchot (847225)]

The set of complex numbers is no less "real" than the set of real numbers. Both are simply definitions arising from some set of mathematical axioms, usually those of an axiomatic set theory like ZFC. In fact, the definition of i as sqrt(-1) that you learn in high school is mathematically unsound: the correct way to define the complex numbers is as the set of ordered pairs of real numbers. When combined with an expected addition (a,b)+(c,d)=(a+c,b+d) and a funky multiplication (a,b)*(c,d) = (ac-bd,bc+ad), this allows you to define a+bi as shorthand for (a,b). (Note that i*i=(0,1)*(0,1)=(0-1,0+0)=(-1,0)=-1, as expected.)

Neither the real and complex numbers are "real" in the sense that they physically exist, but are on equal footing in the sense that they represent real, physical quantities. Complex quantities simply appear when dealing with pairs of real quantities. Take the (complex) wavefunction representing a quantum state, as an example. Sure, you could formulate the Schroedinger equation as a pair of coupled differential equations, but why bother, especially when it's much more elegant to express it as a single, complex equation?

Cayley sedenions are a 16 dimensional field. But zero has divisors in sedenion algebra. Octonion multiplication isn't associative, though. Nor is quaterionion multiplication commutative. It just depends on what characteristics you require for the purpose at hand, really. Froebenius' theorem tells us that only real, complex and quaternionic algebrae are associative division rings over real scalars. But if you only need finite fields (as is often the case in practical applications), an Artinian ring is often iteratively solvable for any given application, of arbitrary dimension.

Negative kinetic energy happens all the time in quantum mechanics. That's what tunneling is. In classical physics, the total energy is E=T+V, where T is the kinetic energy and V is the potential energy. In tunneling, a particle can pass through a "barrier" where V>E, so that the kinetic energy E-V is negative.

I still think the claims in the article are ridiculous though.

Re:Sqrt(Negative energy) = head hurts

[rasputin465 (1032646)]

IAAP, although not in this field (and actually I don't know anything about "phantom matter"). The idea of imaginary physical quantities isn't actually as forbidden as you might think. The best example I can think of are tachyons [wikipedia.org]. Non-physicists invariably hear about these particles in sci-fi (I seem to recall multiple references to them in star trek), but actually a number of current theories predict their existence. They are particles that travel faster than the speed of light, which means that their rest mass is imaginary. You need not worry, however, because they never travel slower than the speed of light. One example, supersymmetery [wikipedia.org], predicts a number of particles whose mass^2 is positive at high energies (read: very soon after the big bang), but goes negative at lower energies; hence their rest mass is imaginary and are tachyons.

Less esoterically, in the realm of electronics, the electrical impedance of capacitors and inductors is imaginary. However, one could argue that this is just a mathematical trick to aid computations.

I might also note (and probably other commenters have too) that Lawrence Krauss, who's mentioned in the summary, is the author of the famous The Physics of Star Trek [amazon.com], which is a great read.

That's not likely, or if it is true, it's not very relevant. Fritz Zwicky [wikipedia.org] first proposed dark matter (in it's current incarnation) back in the 1930s. However, no one else in the field started to consider this idea until the 1970s (Zwicky died in '74) when other independent bits of evidence started to come in that hinted at dark matter. At that time, people in the field were particularly mindful that the problem could be resolved by either dark matter or by modifying our theories. But as time went on, more and more independent pieces of evidence came in which addressed the same issue. Now, the problem is that if you want to account for each of these observations by modifying our dynamica/gravitational theories, you have to do a different modification in each instance. On the other hand, ALL of these observations are resolved by introducing dark matter. The door was virtually shut on modified theories with the analysis of the Bullet Cluster [wikipedia.org], which simply cannot be explained by modified gravitational theories. And actually, dark matter is not so esoteric; there are many current theories in particle physics that [independently] predict the existence of a particle that would meet the characteristics that we observe and would also be naturally produced in large quantities during the big bang.

Are you really that surprised? We worked out how most of the world around us works over three hundred years ago. We put electromagnetism to bed over a hundred years ago.

Our common sense is calibrated for temperatures between about zero and one hundred C in a thick nitrogen/oxygen environment with a 1 g gravitational field. Of course it fails miserably when confronted by absolute zero vacuums or temperatures and pressures extreme enough to fuse matter or places with gravitational fields strong enough to capture light.

Cramer, Robert L. Forward, Michael S. Morris, Matt Visser, Gregory Benford, Geoffrey A. Landis. U.C. Irvine even wrote a press release about this paper [sff.net], which I've put on my website.

It's a little hard to tell from this very brief article, but what he calls "phantom matter" is what other physicists call "exotic matter" or sometimes "negative matter," which violates one of the positive energy-conditions, and thus has negative energy (in some reference frame). Matt Visser's book Lorentzian Wormholes has a lot more technical details about the various formulations of the positive-energy conditions.

This theory

[Z00L00K (682162)]

This theory assumes that the difference between universes (or as they may be called multiverses) can be quantified.

<Speculation>

If not, if the difference is the same as time or length in a dimension that we aren't able to consciously manipulate or see, then it is possible that we all are floating in roughly the same direction, but since the differences are very small it's impossible to recognize if we are in the same sector as when we started our lives.

All this since there are in theory dimensions that we can't see. Why they are invisible is a different question. It may be that we all are mentally and physically unable to "see" the dimensions or that they are "curled up" or "flattened" in a way that makes them immeasurable. This is just about the same question as if you are on a board (like our universe) on a completely friction-less surface where there is no perception of wind and no reference points. You have every perception of everything on the board, but you can't tell if the board is still or if it's actually drifting at the speed of sound with the wind. If you can't even "see" outside the borders of the board (the universe) you can't really tell if there are other universes out there.

And it's not even possible to say if the laws of physics are general or specific for a universe. It may well be that the laws of physics are the same in any given universe, and that we just are inside a bead of glass. (watch the end sequence of Men in Black to catch this idea...). Just "infinity" is hard to catch up, but it's like living on the surface of a globe - where is the end of the world? And if you walk a straight distance on the surface of a globe large enough - will you ever come home again or will you even recognize that as home [hmv.co.uk]?

I think that there is no straight answer, and that Keith Laumer [keithlaumer.com] in the "WORLDS OF THE IMPERIUM" may have one approach, and Robert Anson Heinlein [heinleinsociety.org] had another in "Number of the Beast" (among others), but I think that Douglas Adams [douglasadams.com] got really to the point in the statement "There is a theory which states that if ever anybody discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened.". At least his statement will explain a lot.

But this is still in the area of speculation, and I think that it's hard for the human race to get outside the universe. But I don't say that it's impossible - there may be a discovery around the corner waiting to happen!

</Speculation>

What is most important is that we try to keep our minds open - there may be a grain of truth in every theory that at first sight may appear ridiculous. Notice that the continental drift [geekculture.com] was considered completely outrageous [wikipedia.org] by many until the end of the 1950's. The continental drift is now a widely accepted fact (but there may still be those that doesn't accept it).

Gandhi [brainyquote.com] once said "Nearly everything you do is of no importance, but it is important that you do it.", and this still applies.

Where's the violation?

The first law states, "The increase in the internal energy of a system is equal to the amount of energy added by heating the system, minus the amount lost as a result of the work done by the system on its surroundings."

Accordingly, since no energy is being added to the system, its internal energy must not increase. That's fine, because in you example, the total energy does not increase.

Energy is usually measured in joules. 1 joule is, reduced to base units, 1 kg * (m^2/s^2). So the total energy of your system is defined as:

Joules = (1000 * [x^2/y^2]) + (-1000 * [x^2/y^2])

Now, if x is 0 and y is 0, (the system is at rest), then the energy of the system, in joules, is

Joules = (1000 * [0^2/0^2]) + (-1000 * [0^2/0^2])
Joules = (1000 * [0/0]) + (-1000 * [0/0])
Joules = (1000 * 0) + (-1000 * 0)
Joules = (0) + (0)
Joules = 0

If x is 10 and y is 1, then the energy of the system, in joules, is

Joules = (1000 * [10^2/1^2]) + (-1000 * [10^2/1^2])
Joules = (1000 * [100/1]) + (-1000 * [100/1])
Joules = (1000 * 100) + (-1000 * 100)
Joules = (100000) + (-100000)
Joules = 0

If x is 500 and y is 2, then the energy of the system, in joules, is

Joules = (1000 * [500^2/2^2]) + (-1000 * [500^2/2^2])
Joules = (1000 * [500/4]) + (-1000 * [500/4])
Joules = (1000 * 125) + (-1000 * 125)
Joules = (125000) + (-125000)
Joules = 0

If x is 1 billion and y is 1, then the energy of the system, in joules, is

Joules = (1000 * [1E9^2/1^2]) + (-1000 * [1E9^2/1^2])
Joules = (1000 * [1E18/1]) + (-1000 * [1E18/1])
Joules = (1000 * 1E18) + (-1000 * 1E18)
Joules = (1E21) + (-1E21)
Joules = 0

Since 0J = 0J = 0J = 0J, no matter how fast the two-ball system accelerates, there is no violation of the first law of thermodynamics.
