Lorentzian Space to Euclidean Space (Really Strange Stuff)

O.k. this is strange (from the physics arxiv blog found on Slashdot):
It don’t get much weirder than this. The universe is about to lose its dimension of time says a group of theoretical astrobods at the University of Salamanca in Spain. And they got the evidence to prove it.

The idea comes from the study of braneworlds: the thinking that the universe we see around us is a 4-dimensional cosmos called a braneworld embedded in a multidimensional universe. The “signature” of our universe is the number of space and time-like dimensions it has: in our case we got 3 space-like dimensions and one time-like dimension. It’s what astrobods call a Lorentzian universe. So far so good: lots of astronutters think the same thing.

But our universe may not always have been like this. Some theorists think it may once have had a Euclidean signature meaning that all the dimensions were space-like. Now Marc “Bars” Mars and a few pals in Spain say that the Universe’s signature might be about to flip from Lorentzian to Euclidean. In other words, our dimension of time is about turn space-like. Gulp!

This ain’t entirely bonkers and here’s why. Bars Mars has calculated what it’s like to be an observer in a universe that is about to flip and get this: it would look as if it were expanding and accelerating away from us. Sound familiar?

Yep, it’s exactly what astrobods have been observin over the last few years, a phenomenon they attribute to dark energy. If Bars Mars is right, dark energy ain’t got nothing to do with it and we’re all starin’ down the barrel of a cosmic catastrophe.

Still, maybe four space-like dimensions will be better than three. Who needs time anyway?

Bonus:

Erin Pavilina’s Dream:

Mainly catastrophic disasters like meteors, lava, tidal waves, a total shift of the planet’s alignment or something that causes the same type of reaction. Most people die, but some are taken aboard vessels and rescued.

But I’ve also seen something else. A phasing into a different dimension. It’s really hard to explain, but it was not pleasant. I want to say there was a reptilian race involved and they kept humans in this strange state of being phased between the 3rd and 4th dimensions and were feeding off our energy.

The vessels people boarded were of the “light” and the reptilian thing was definitely of the “dark” and it is unclear who will prevail.

I don’t know if this is true or not but it would make a hell of a story.

Why America Must Stay in Iraq

First off let me tell you I have never voted for ANY Bush past or present and I’m proud of that. Secondly, I did NOT agree with going to Iraq to search for fuckin’ WMDs or for OIL (operation Iraqi Liberation) or any other reason, particularly when we had allegedly been attacked by TERRORISTs not by Iraq, Iran, North Korea or any other member of the cartoonishly infamous “axis of evil”.

I do believe that there are terrorist who want to destroy America, but prior to America’s preemtive strike on Iraq they didn’t have the numbers, motives, power or news coverage that they do now. The war in Iraq has possibly made internation terrorism have a united cause.

I actually agree with 94′ Dick Cheney’s views on why it is a bad idea to take Iraq:

So why, then do I think we should stay? I see it as our responsibility to help the Iraqi people out of this chaos that was created by uprooting the structure they had in place. I am not an apologist for Saddam Hussein. I believe he was an evil man who violated the UN resolutions (a violation punishable by war, I might add). And though I think it was a VERY bad idea to unleash this “quagmire” that is now up to nearly half a trillion dollars (at a time when America itself faces a baby boomer social security disaster) we have an obligation to follow through. If we bail on the Iraqi people it will be worse than mere cowardice, it will dishonorable, heartless and above all, it will be betrayal. The same kind of betrayal that the U.S. exhibited in the Gulf War when we abandoned the Kurds and the resistance that rose up when we and many other nations stomped Saddam and got him out of Kuwait.

While I think we should stay in Iraq, I don’t buy into the AM radio, RUSH-Ditto-headed, “We have to win for OUR freedom” BULLSHIT! Its the height of arrogance to pin the successes of a stable Iraq in our hands for our own purpose when all the heavy lifting MUST be done by the Iraqi people. Yes, we will be will benefit by their stability but it is their country. We can help them attain stability, but ulimately success is in the hands of the Iraqis.

What annoys me about the Democrats and main stream liberals rhetoric is that they claim to want prosperity, health and love for everyone, but they want to bail out on the Iraqi people. I mean, yes it was wrong to go! Yes, the Bush administration sucks, but the fact is that we are there NOW and those people are suffering because of our actions.

Leaving Iraq now would be like a hit and run. We could call it “Sucker Punch” Diplomacy. It is sad that only the war mongers that flirt with a nuclear world war III (Guiliani) are the only ones who want to stay in Iraq and even they want to stay because, “We have to win for OUR freedom.”

I believe it is our moral and spiritual duty to stay in Iraq. Not for some BS religious reasons or devious political and strategic reason, but because there are people there (woman and children) who just want to live their lives.
