Thanks for this pair of contributions to the contest.
I was really amazed by the fact that you use the conditional tense all along your discussions of the physics part of this blog. This is a very good thing to do here, as we do not have any certainty about any of the points risen. However, it is important to explore those possibilities, so that we could be ready in the case they are true.
Cheers!
PS: I have a (slight) preference for the second collage ^^
Thank you @lemouth for visiting. It has been an amazing contest. I never thought so many people would get into 'dark matter', but it seems to have really struck a chord. We all wonder at the universe and this contest invited us to dwell on that wonder.
It is the mystery of dark matter that is so attractive, I think. Humans like horizons. We are wanderers, adventurers. Why stop at earth? :)
BTW, my husband likes the first collage. They were both fun and an invitation to learn.
Hope you are not too busy with the contest and your teaching duties.
Take care.
