There is wind where the rose was,
Cold rain where sweet grass was,
And clouds like sheep
Stream o'er the steep
Grey skies where the lark was.

Nought warm where your hand was,
Nought gold where your hair was,
But phantom, forlorn,
Beneath the thorn,
Your ghost where your face was.

Cold wind where your voice was,
Tears, tears where my heart was,
And ever with me,
Child, ever with me,
Silence where hope was.

NatashaTNatashaT Posts: 1,092 Teacher
We read an article about the discovery of Einstein´s gravitational waves:

http://www.abc.net.au/news/2016-02-11/einstein's-gravitational-waves:-what-do-they-mean/7159238

Vocabulary Top 10:

ripple - a small wave on the surface of a liquid

to and fro - forward and backward, from one place to another

undergo - to experience or endure something

elusive - hard to find or capture, or hard to understand, define, or remember

coalesce - to come together to form one group or mass

extent - used to indicate the degree to which something exists, happens, or is true

curvature - the amount that something is curved

no mean feat - something that is difficult to do

in turn - following one after another in a particular order

telltale - indicating that something exists or has occurred


In Wednesday´s Night Owl session we will finish reading the article (starting from ´Haven't we heard this news before?´) and then talk more about black holes, waves, and other astronomical things!

    Thank you for helping us reading this article, @Natasha.
    It's not an easy topic, but with your help we understand more now :) .
    The black holes in the picture from your link are at least not as frightening as in another pictures like this one


  • NatashaTNatashaT Posts: 1,092 Teacher
    You´re right @april , those black holes are scary!!!
  • aprilapril Moderator Posts: 11,015 mod
    How do they know it looks like that, I wonder!
  • BubblyBubbly Posts: 29,890 ✭✭✭✭
    I couldn't get these lines. :)

    All objects sitting in the path of gravitational waves rhythmically move further apart and closer together as the space they exist in is stretched and squeezed.
  • NatashaTNatashaT Posts: 1,092 Teacher
    @Bubbly - Imagine being on a calm lake, in a boat. Then a fast jetski goes past, and makes waves in the lake. All the other boats and objects floating in the lake move around, and they move towards or away from each other, in time with the waves. The lake is like space, and the jetski waves are the gravitational waves.

    (I hope that helps, and doesn´t confuse you more!)

    Extra vocabulary:

    arduous - very difficult

    dry run - a practice event that is done to prepare for the actual event that will happen in the future

    retract - to say that something you said or wrote is not true or correct; to take back (something, such as an offer or promise)

    rigorously - in a very strict and demanding way; done carefully and with a lot of attention to detail

    Question: Do you think this is a useful discovery? Why or why not?
  • BubblyBubbly Posts: 29,890 ✭✭✭✭
    @NatashaT thanks for the explanation. I got it once I read the whole article. But, you made it simple and easy for me. :)
  • ElvinElvin Posts: 454 ✭✭✭
    a nightmare... :D
  • BubblyBubbly Posts: 29,890 ✭✭✭✭
    @Elvin hopefully, this is not your guess for the GTT #17. ;)
  • ElvinElvin Posts: 454 ✭✭✭
    No, @Bubbly, this topic about gravitaional waves is everywhere, I can't avoid it, like a nightmare. :)
  • BubblyBubbly Posts: 29,890 ✭✭✭✭
    @Elvin I've already predicted. ;)

    Well, actually I asked Her majesty the queen Elizabeth to read this article for group Skypers. She was very kind and did me this greatest favor. You can listen to it here.

    @Vahnin - now I´m a little confused! Do you still want to read it during one of the sessions, or do you just want to listen to the recording on your own?
