Several of your sentences are complex and your opening sentence describes a Black Hole quite clearly.<br /><br />Keep up the great work! I'm enjoying your writing and particulary your writing style.<br /><br />Cheers<br /><br />Ms ScottMs Scottnoreply@blogger.comtag:blogger.com,1999:blog-7726590324459993231.post-22631321595308926362013-02-28T17:49:17.577+11:002013-02-28T17:49:17.577+11:00Hello Mrs Yore and SMY,

It's the singularity that is the remains of a collapsed star. So intense is its gravity not even light escapes.<br /><br />But wait, have you ever read light travels in a straight line? If this is so, why can't light escape? Light from the singularity travels in as straight a line as space allows. The singularity warps (bends) space itself so the light, in a way, bends. From the outside we see, if anything, an area where no stars are seen, a black hole.<br /><br />Did you know it's proposed there is a huge singularity in the middle of our galaxy? Imagine what turmoil must be happening in that region of space as matter is sucked in.<br /><br />Sucked in? Maybe you have heard of the event horizon? It’s a point of no return. It’s where anything caught in the intense gravity of the singularity can’t escape. Think of a hill sloping gently at first but getting steeper and steeper. You start walking but eventually you find yourself running and then falling when the slope becomes too great. Now imagine you’re a planet or star. What a journey that would be as the gravity pulls it apart.<br /><br />Back in 1987, we were informed of a position in space. A star had appeared to the “naked eye” where once the only trace would have been from large telescopes. A star had gone supernova. Astronomers labelled it SN 1987A.<br /><br />Supernova link - http://en.wikipedia.org/wiki/Supernova<br /><br />What is amazing is the star was about 168,000 light years distant. This means the light from the supernova took about 168,000 years to reach us. While we could see it in 1987, the supernova had really taken place about 168,000 years ago.<br /><br />When we look at the stars, we are looking into the past. In a way, we become time travellers. How amazing is our universe?<br /><br />@RossMannell<br />Teacher (retired), N.S.W., Australiarmannellhttps://www.blogger.com/profile/10325881715643049499noreply@blogger.comtag:blogger.com,1999:blog-7726590324459993231.post-6206696544430634882013-02-26T17:55:20.576+11:002013-02-26T17:55:20.576+11:00Hi SMY

I also like the very discriptive writing keep up the good work.<br /><br />From Matthewg :) :( :|Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7726590324459993231.post-41130367278968052932013-02-26T11:17:32.884+11:002013-02-26T11:17:32.884+11:00Well written Madi, I think you have achieved the r...Well written Madi, I think you have achieved the requirements of this writing task. Black Holes still have much to be discovered about them, but as 'no matter can escape,' it would be difficult to explore everything about them without losing all of your equipment!<br />Happy exploring and learning. <br />Mrs Bellesini :)Anonymousnoreply@blogger.com
