HOW FAR IS 3 BILLION LIGHT YEARS
If you mean the constellation Virgo, that is a direction in the sky, basically. The answer is of no use to you.
DESCRIPTION: And a lighthour is 60 lightminutes, or about million miles. Have you people never heard of Google calculator? Record-breaking star system
Science on the Brain - How far is a lightyear?
Sometimes astrophysicists distinguish between the visible universe, which includes only signals emitted since recombination —and the observable universe, which includes signals since the beginning of the cosmological expansion the Big Bang in traditional physical cosmology , the end of the inflationary epoch in modern cosmology. Pretty cool, I think. To give an idea of 1, light years, if you were driving at a law breaking speed of mph, it would take you nearly 11 billion years to get there.
- How far away are light years?
- That same year, an unusually large region with no galaxies was discovered, the Giant Void , which measures 1.

- Astronomers say they have found the most distant galaxy in the universe, called EGS-zs, measured at
Lets see if I can't manage to get that on a managable scale, huh? An opposite effect works on the galaxies already within a cluster: The most famous horizon is the particle horizon which sets a limit on the precise distance that can be seen due to the finite age of the universe. If the whole galaxysuddenly winks out and disappears tomorrow, we won't know about it for another 13billion years.
And a lighthour is 60 lightminutes, or about million miles. The density of ordinary matter, as measured by Planck, is 4. Since light moves atmiles per second, a lightsecond ismiles.
Using a longer yard stick, so to speak, helps keep the numbers at least manageable. For example, galaxies behind a galaxy cluster are attracted to it, and so fall towards it, and so are slightly blueshifted compared to how they would be if there were no cluster On the near side, things are slightly redshifted.

Given that the human mind cannot possibily comprehend the vastness of the cosmos, it can be forgiven for choosing to ignore it. Bing Site Web Enter search term: Adam Evans via Wikipedia. Fri Nov 17,
Just how far is 13 billion light-years?
Stars are organized into galaxies , which in turn form galaxy groups , galaxy clusters , superclusters , sheets, walls and filaments , which are separated by immense voids , creating a vast foam-like structure  sometimes called the "cosmic web". So you're assuming the jet ski travels at about 40 mph then? Puppies as young as two-months old naturally trust humans 'like they are their own mother' even if they are strangers Cocaine flushed into rivers by humans is causing endangered eels to get high and damaging their ability to reproduce Wimbledon tennis to be screened in Ultra HD by the BBC for the first time despite technical glitches with the technology in streaming the World Cup The death of the car key? What were chimps 1 billion years ago? However, what we're seeing now is light from objects that were that far away when they emitted the light.
If we scale the astronomical unit — the Earth-sun distance — at one inch, then the light-year on this scale represents one mile 1. Retrieved 17 October OK, Ars throwdown tommorrow, location:
A light year is a unit of length equal to just under 10 trillion kilometres. The entire universe will disappear before our very eyes, and it's one of my arguments for actually funding cosmology. The density of ordinary matter, as measured by Planck, is 4. What were chimps 1 billion years ago?

Excellent post, thanks for sharing!
she likes cock up her hairy cunt and wants it so much fucking.
Oh please someone make me your rubber slut!
that good actors haaaa . bastards
Would love to see my wife fucked by a huge cock.
