200,000 Elliptical Galaxies Point the Same Way
slashdot.org ^ | 29 aug 2007 | KJ Longo

Posted on 08/30/2007 6:47:29 PM PDT by jbp1

I have studied a sample of 200,000 elliptical galaxies with redshifts <0.20 from the Sloan Digital Sky Survey (SDSS) to investigate whether they tend to have their ellipticities aligned along a particular axis. The data show a 13 standard deviation signal for such an alignment. The axis is close to the spiral spin axis found previously and to that of the quadrupole and octopole moments in the WMAP microwave sky survey

Ah ! This is proof positive of global warming. Two billion Galaxies have joined us today to get the message out that we have to stop using SUV's

And God Said

∇ • E = ρ / εo

∇ • B = 0

∇ x E = - ∂B/∂t

∇ x B = μoJ + μoεo∂E/∂t

And there was light

So

Do they point to the right or the left?

Just wondering.

Maybe it's important or something.

It’s a reverberative echo of Babe Ruth, calling his shot.

I created a great thought problem for astronomers, which I call the “time machine game”.

Some inventive genius creates a time machine that can take him either into the past or into the future. But unlike science fiction time machines, this one *doesn’t* move through space as well. With all the different speeds and directions we are traveling through space on spaceship Earth, all at the same time, when he materializes, his time machine is a long way away from where he started, most likely high up in the sky or inside the Earth, after even just a few seconds.

This means that either going back in time a year, or going into the future a year, the time machine is going to materialize out in empty space, the planet Earth no longer being where it was a year ago, or having not yet arrived at where it is going to be in a year.

But the question is: in what direction, in the past, or in the future?

To make things easier, just disregard the daily turning of the Earth, and since it is exactly one year in either direction, it will be in the same relative position around the sun.

But you need to figure out what direction the solar system is moving through the galaxy, and the galaxy is moving through the universe, to figure out where the Earth, and thus the time machine, was a year ago, and where it will be in a year.

That is, from the point of view of Earth, right now, you should be able to draw two lines into space, pointing in whatever direction the Earth was a year ago, and will be in a year.

Interestingly, if the time machine could *also* move in time relative to its location also, like a science fiction time machine, using some creative math, you could travel around the galaxy in your time machine by going into the past and the future, then *not* travel as you go in the other direction in time.

That is, say traveling into the past until where you want to be is where you are; then traveling into the future *with* that point in space until you are back in the present, but say, on the other side of the galaxy, which is where you traveled to is, in the here and now.

But to win the game, you should be able to look into the night sky, in the general direction of some stars, and say that that relative direction was where Earth was a year ago, and look at some other stars and say, and that is the direction where we will be in a year.

Didn’t their mothers teach them it’s not polite to point?

I’m not sure if it’s an Octopole moment or just Miller Time.

Google earth now has something similar as well.

Don’t MRI machines take their images by lining up the hydrogen nuclei in all of the atoms in your body so that point the same way?

So...I get it...maybe we’re all in some sort of incomprehensibly colossal MRI machine. Yeah, that’s it. And...the solar systems and galaxies are all just atoms and molecules inside some being’s equally incomprehensibly huge body. And...the body is being medically scanned (by God?) And...the prognosis is, “weird.”

Man, these science articles really make you think.

They all point at me.

I am at the center of the universe and I can prove it.

No matter what direction I face, the distance to the edge of the universe is infinite.

Ergo, I am at the center of the universe.

The same is true for you.

Sincerely,
Lola Granola

The Restaurant at the End of the Universe is owned and operated by Chuck Norris. Actually, there are two of them, one at each end. He exercises by running from one to the other, which he can do in 42 minutes.
