SPACE (Our Univers)

 Are you seen a sky in night? The night sky has trillons of star. Many of these are visible to the nacked eye on a clear night.We can also see some of the planet that orbit our sun,as well as the moon.All this objectare a part of our univers.

How ever,they aren't the only part of our univers. the star and planets that we can detect are only a tiny part of everything that's out there. the observable univers isa sphere that is a little over 90billion light years in diameter.(Approximately1 light year-9500000000000 kilometers)The rest of it is invisible to us because the originating light, post the big bang theory, hasn't even reached us yet.

                                            

                                              OTHER THEORY OF OUR UNIVERS...

The big bang is the most popular theory in existence today. However,there are and probability always will be others competing with this one. Some of the originally proposed theories have already been discarded. A theory is discarded if what has been observed of the univers does not match the predictions of the said theory.

                             SOME OF THE MORE COMMON THEORIES ARE EXPLAINED BELOW.

OSCILLATIPON MODEL THEORY; it state that the univers is a cyclic process.

STEADY STATE THEORY; here,it is believed that the univers has no beginning or end.Matter is begin continiously created.The theory is not prevalent at the moment.

HAWKINGS TUROK THEORY; This theory states that the univers was instantaneously created from the tiny particle like a pea.
