The universe is considered as a black body...does the universe emit radiations outside or inside(read details)

Question

The sun is considered as a black body .. it emit radiations to the outside .. these radiations reach the earth ...
how is the universe considered as a black body ... we are inside the universe ... however we get the CMBR red shifted 380000 years after the big bang ... Does the universe emit radiation to the inside ?

Answer 1

think of it this way... the expansion of the universe is indeed a rapid process, but at it's fastest it is nowhere even close to the speed of light... So if radition is emmited by a body on the edge of the universe, it will emit it spherically and because the radition heading "inwards" moves faster than the body emiting it is moving "outwards", you can't help but get inward radiation.

Answer 2

Scientists now say that the universe replaced into formed via a blend of the 'massive Bang' alongside with a consistent State. they say that the completed obtrusive universe emerged from a warm fireball of ability occupying a volume smaller than an atom, 13.7 billion years in the previous. mild is area of the electromagnetic spectrum. The planets and so on ought to simplest variety, after inflation, with the ripples of the initial explosion from that atom being at a distinct state. Smaller ripples, and there should be no longer something thrilling; more advantageous ripples, and the universe should be too violent. The inverse sq. regulation of gravity facilitates secure orbits to exist. it truly is what scientists quaintly call 'cosmic coincidences'. Now bear in mind what the author to the Hebrew Christians in the first century said about God transforming into the universe: "with assistance from technique of religion we comprehend that the universe replaced into formed at God's command, in simple terms so what's obtrusive replaced into now no longer made from what replaced into obtrusive." (Hebrews 11:3) An atom is invisible to us. The universe got here from ability compacted into something below the length of an atom. Is the Bible ideal, or is the Bible suitable? Even shown atheists, like the author of the e book below, say such issues as, "...The question of even if the Universe known by chance or layout, suggesting an reply that replaced into no longer what i replaced into looking forward to once i began gazing on the information. ...The Universe is comprehensible to the human mind pondering the actual shown actuality that it replaced into designed, in any case to a pair extent, with assistance from utilizing smart beings with minds a twin of our own... The Universe replaced into really put in to grant a living for life... The Universe replaced into once created in the picture, type of, of the universe of the Designers." This author denies there's a author God, even if. strong, no individual is often proper about the completed element.

No. The universe is neither black, nor does it emit anything. The universe consists of, Now Listen Closely, NOTHING!! What kind of fool do you have for a teacher? The Sun isn't black, not even in Africa!
And the universe was NOT created by a big bang or anything else. It just is.

Black body is a physics term that means given an object with a certain temperature that the radiation coming from it will follow a certain shaped curve as far as wavelength goes. It doesn't mean anything is black.
