Don’t forget the Great Attractor.
Terrifying indeed. But, you don’t need to lose sleep over it.
Trump will keep you up in the night anyway.

The Big Bang – or the Big Bounce? – https://www.ft.com/content/f47b8310-0383-11e7-ace0-1ce02ef0def9 via @FT
Whether it is big bang or big bounce, this is by far the best and easiest-to-understand article about “Big Bang,” written by Sean Carrol for people with no knowledge of how space and time work in the universe that we are in now. It’s an easy and enjoyable read.

I am sure you have questions like:
。What’s before the “big bang?”
。Did the “big bang” bring with it the beginning of time?
。Was there no time before the “big bang?”
The scientists have no answers for us common folks just yet. They might in a decade or a century.
But who is counting? After all, the universe has existed for 13.8 billion years, give or take a few millions.
It can wait.

I saw this on the BBC and thought you should see it:

Taiwan is in the danger zone and an app like this from Berkeley will one day be useful to generate alerts.
林口 (Linkou,) where I live, is not known as an earthquake hot spot in Taiwan so that it is not likely that my phone will pick up any major earthquake near my house soon. However, when I travel to other regions in Taiwan, it might become useful.

Even though I don’t understand the science discussed in this article, I enjoyed reading it a lot.
Topics like this one has always been fascinating to me.
