New, sharper image of the early universe

[BDub85]

released July 5.

And finally, this sub forum came thru. Bout time.

edit: Planck, the scientist who recorded the image, purposefully downgraded it so no one would begin to draw any "premature conclussions". Pretty sh!tty move. The red and yellow parts correspond to early radiation. The blue and white is Milky Way interference.

[Hardcore_D00d]

Someone explain how they can get a picture of the universe in its early phase? arent we living in the universe right now so basically thats a pic of us somewhere but how can they get a pic of the whole thing O.o

[BDub85]

by measuring raditation at the edge of the known universe

[Otaman]

what is the black stuff around it?

does universe have limits?

This might not be entirely right, but the further out into deep space you get, the longer it takes light to travel.

here is an example, a supernova happens over millions of years ago, but we just now see it (at its earliest stage) because its light is just now getting to us. In effect, the same applies to galaxies and planets. (when you look at the stars, you are seeing them at a far earlier stage) That is how large space is. Crazy mind = blown type **** there brah, and I might not have explained it perfectly. If someone feels the need to correct, have at it.

Deep space brah. You're thinking of galaxies and all the star clusters in them. Outside of galaxies, there isnt much if anything out there. But there are trillions upon trillions of galaxies scattered throughout deep space.

The picture above is of the milkyway galaxy (the galaxy that our solar system is in).

so basically correct me if im wrong, the galaxies and supernova pics we have we are looking at the past them? So one of em could explode right now and we wouldnt even know until like 10,000 years from now?

I am no Astrologist, but I think it goes something like this.

Light, travels really fast ( 186,000 mi/sec )

However, as fast as that is...The Universe is HUMONGOUS let me just give a number (although I am crazy wrong) say the Universe is 1 Trillion Miles big. That means if you were to go from point A (edge of 1 side of the universe) to B (the other edge of the universe) that means light will take approximately 89,605 hours to reach the other end. (If I calculated right)

So since our eyes only see light and the reflection of light, that means if we are on either point of the edge of the universe it would take 89,605 hours for us to see it with our eyes, or telescopes.

So, after the Big Bang (which moved things/earth/us faster than the speed of light) we moved further than light and it still has yet to reach us and we are seeing more and new things in space all the time. I think that's how it goes.

Best way I can explain it.

Yup, Most deep space objects you see with telescopes(IE Hubble because its the most popular).
Are hundreds of thousand,million, billions years old.When you look up into the night sky and you see stars, you are looking into the past because it took X amount of light years to reach us.

[jujuB]

have you guys seen through the wormhole with morgan freeman?

i remember him saying that the big bang was so fast, there is actually a named amount of time for it.

something like it expanded to it's current size within 1 millionth, millionth, millionth, millionth of a second... 4 times over.

it was either a millionth, or a billionth.

[Rockchalk0420]

Correct. Because its light will not have reached us till 10,000 years from now.

Its essentially a time elapsed photo of deep space's radiation. Also known as the cosmic background radiation. The milky way interference is because the photos were taken from Earth, thus the rest of our galaxy gets in the way. An idealized image would visible displaying an angle at maybe a 30* up and down, both ways.

[Hardcore_D00d]

quick question is our galaxy/solar system moving around like fast and we just dont notice because we are small. not orbiting i mean like moving away or something

[moosecakes4all]

It is both spiraling (very fast) and moving away from other objects (very fast too).
Current theories in physics state that objects closer to use are moving away at rate say, x, and objects twice as far from us are moving at a rate of 2x.
Thus if we were to take a paper, and draw a 12 x 12 plot of points, one point on top of the next, and overlay it with an exactly identical plot, and each point represented one galaxy near by. Then we were to compare it after say, 1 year you could pick ANY dot on that plot, and say it was our home, earth, every single other dot will have shifted away, and the further from our vantage point, the further the dot will have shifted!

[Hardcore_D00d]

what would happen if it came to a sudden halt? would we all die?

What? That picture is supposed to be of the background radiation of the entire universe, the milky way is just interference. The black is not "deep space" as you're calling it (the space between galaxies), but what lies outside the edge of the early universe.

It doesn't take light hours, it takes light years

It is not "deep space", nor is it the edge of the universe, no one knows if the universe has an edge. Id guess that its just been cropped to be like that.

A baby pic of the universe ^^


If you guys ever read about COBE (cosmic background explorer) "The COsmic Background Explorer (COBE), also referred to as Explorer 66, was a satellite dedicated to cosmology. Its goals were to investigate the cosmic microwave background radiation (CMB) of the universe and provide measurements that would help shape our understanding of the cosmos."

http://en.wikipedia.org/wiki/Cosmic_Background_Explorer

The WMAP "Wilkinson Microwave Anisotropy Probe (WMAP) is a NASA Explorer mission that launched June 2001 to make fundamental measurements of cosmology -- the study of the properties of our universe as a whole. WMAP has been stunningly successful, producing our new Standard Model of Cosmology. WMAP continues to collect high quality scientific data."

These 2 pictures show the afterglow of the Big Bang, the microwave radiation shown is radiation from when the universe is believed to be about 380,000 years old.



Now recently, the Planck Satellite, launched May 2009 by the European Space Agency has recorded the most up-to-date, highest resolution picture of the baby universe. Before you look at the picture, look back at the top and then look at this new scan.




























http://i26.tinypic.com/5vnj4k.jpg


"Planck’s map depicts subtle variations in the universe’s temperature at different points in the sky, reflecting the distribution of matter when the universe was 380,000 years old. White and blue areas represent foreground interference from the Milky Way and other galaxies; that data must be subtracted before the primordial microwaves (represented by the yellow and reddish portions of the image) can be fully analyzed."

The picture is of the visible universe. And if we could go 5 billion light years farther, our visible universe would move according to our point of view, and the radius the age of the universe.

funny thing is if we ever developed ftl travel we could setup telescopes aimed at earth at different distances and be able to record our past if they were strong enough to recored what's happening on the surface. no more need for archeology and all that jazz.

[kenonator]

how can the light from something so many million years old reach us if the earth is only 6000 years old....................







waitwut?
