Dark energy theory wrong? Is nickel the key to understanding the fate of the universe

How you choose to define your existence over mine is semantics. Where you see illusion I see truth. Dreaming allows me to know that I exist.

It all matters.

How true! Well, everything save for the first sentence. Much respect. =D

All very interesting but until you realize everything is wrong and can never be right, you'll finally realize the incredible breadth of mortal ineptitude.

Thats precisely the reason we need to find out more and contemplate it, to try to shrink the breadth of said ineptitude. If we dont end up destroying ourselves we've got a pretty long time to figure things out more. I believe the oldest known fossil from our species itself was recently found in israel and dated to before the oldest fossils we had found in africa, that was dated to about 400,000 years ago. Also means the old theory of humanitys spreading out and where we originated from in israel just may be correct, but anyway, look at the progress we've made in approximately 402,000 years and our technologies are advancing at some incredible rates. That time period is absolutely miniscule compared to the time the earth has and will be around. Even if we get nailed by a comet or something in a million years and thats all the time we get imagine 1 million years in the future and what humanity may achieve, now lets say we get lucky and live for a decent amount of time, imagine 5 million years ahead, imagine 10 million years ahead, imagine 50 million years. If we survive that long we will find the answers. lol

All that means is that once again we were wrong. And will be again.

An interesting discovery was made by nasa's fermi gamma ray satelite, they found a new phenomenom never before seen, some thunderstorms emit measurable anti-matter from terrestrial gamma-ray flashes (TGF), about 500 occur everyday.
http://www.sciencedaily.com/releases/2011/01/110111132721.htm

heres a more compact version explaining it,
The beam continued past Fermi, reached a location, known as a mirror point, where its motion was reversed, and then hit the spacecraft a second time just 23 milliseconds later. Each time, positrons in the beam collided with electrons in the spacecraft. The particles annihilated each other, emitting gamma rays detected by Fermi's GBM.
Scientists long have suspected TGFs arise from the strong electric fields near the tops of thunderstorms. Under the right conditions, they say, the field becomes strong enough that it drives an upward avalanche of electrons. Reaching speeds nearly as fast as light, the high-energy electrons give off gamma rays when they're deflected by air molecules. Normally, these gamma rays are detected as a TGF.
But the cascading electrons produce so many gamma rays that they blast electrons and positrons clear out of the atmosphere. This happens when the gamma-ray energy transforms into a pair of particles: an electron and a positron. It's these particles that reach Fermi's orbit.
The detection of positrons shows many high-energy particles are being ejected from the atmosphere. In fact, scientists now think that all TGFs emit electron/positron beams. A paper on the findings has been accepted for publication in Geophysical Research Letters.
NASA's Fermi Gamma-ray Space Telescope is an astrophysics and particle physics partnership. It is managed by NASA's Goddard Space Flight Center in Greenbelt, Md. It was developed in collaboration with the U.S. Department of Energy, with important contributions from academic institutions and partners in France, Germany, Italy, Japan, Sweden and the United States.

If you didnt know a positron is the anti-matter version of an electron, when the two collide together they annihilate each other and release all their energy fully.

And I suppose they have a theory as to how anti-matter is apparently magically manifested into reality thru an incredibly exotic means.

One thing i think of alot has been that lets say we somehow did confirm like the multiverse/membrane/ theories of the origins of our universe we would still not know if their are infinite sheets or any of how it works, and how/why/when they came into existence in the first place.

Just based on the fact that their ARE limits, means that their AREN'T limits according the infallible law of symmetry. If something can be infinite, then literally ANYTHING is possible. If anything is possible, then no theory can be completely disproven, just as no theory can be completely proven. Whoever came up with the maxim 'Anything is possible' is the smartest person to live. Believe me, 'anything is possible' is the only right answer to a problem. Dark energy could be real. The world could be flat. Woman could have been made from a man's rib, a person can travel through time. Infinite is the answer to any physics formula. I assure you.

actually the unuiverse is pretty asymetric, We've found some examples of it. like why is their so much matter and not much antimatter? if they were symetric equal parts of both should of formed and the universe should of anihilated completely.

There is good, and there is evil. There is positive, and there is negative. There is light, and there is dark. You yourself said there is antimatter. There is a universe where the majority is antimatter. LOL They probably just call it matter. And call our 'brand' antimatter.

i guess you could look at it that way, antimatter is matter of the opposite charge, it is still matter either way and made up of the same particles, they just have a negative charge, the whole concept of good and evil and light and dark are not relevent to a discussion of the symmetry of the universe/multi verse. Good and evil are something humans use to judge our own feelings/actions, in reality neither existed before we came up with it. Is a shark eating baby birds evil? Is a pack of wolves taking an elk calf evil?is a pride of lions taking down a baby zebra evil? Is it evil that stars exist and blow up? is it evil if that star were to have some form of life on a planet nearby that got wiped out? Is a suppermassive black hole thats in quasar mode evil because it spews back out the high energy jets of matter at close to the speed of light evil? Evil is our own concept, it has no relevence to figuring out physics and cosmology and science. Light and dark are not related really other than the fact they prove all things are not equal, the universe is getting larger. what is darkness? empty space that does not have photons/rediation illuminating it? something we cant optically see? as the universe gets bigger the amount of darkness should be getting further and further from being symetic with the amount of light.

Opposites attract baby, if there is dark energy, there is light energy.

you mean gravity and dark matter which try to keep things bound together? dark energy is not actually dark per se, we use the term dark as in we dont really understand how and why it exists/acts the way it does and is expanding/inflating our observable universe. Gravity would be the opposite of that, not light energy, and right now gravity is getting its ass kicked.

My Brain Hurtz.

If gravity is descended from the latin word gravitas which means 'Heaviness' the antonym for that would be levitas meaning 'Lightness'. If there is theoretically a graviton there should be a leviton. Dark energy and gravity sound like antimatter and matter. Two very similar things, albeit on opposing sides.

Gravity is the result of a spacial distortion.

Imagine a rubber sheet. You place a heavy lead weight in the center of the sheet. As a result, the sheet sags, dipping to a low point where the weight is located.

If you were to take a smaller marble and try to roll it to the other side it would get caught in the indentation and "toilet bowl" circle the weight, eventually falling into it.

That's basically what gravity is. Not a force really, more like the matter isn't "supposed" to be there. So space-time distorts and objects continue along a straight line through curved space. The more the gravity, the greater the curvature. Hence the slowing of time near a black hole.

You are really confusing a lot of different things, trying to make them seem related and opposite... Yet the fundamental flaw in the argument is that you're defining it wrong.

Anybody that has watched the science channel for a little bit knows this much. I'm just playing the science game with you guys. The fundamental flaw with everything is that it is wrong. LOL

i think the crypt is just saying things. half of it makes no sense lol

My point exactly. This is all I'm saying. Well, actually I'm say everything makes no sense, not half. But that's a very astute observation Luger.
