Space – One Writer Ranting

Astronomers estimate that the observable universe has more than 100 billion galaxies. Our own Milky Way is home to around 300 billion stars, but it’s not representative of galaxies in general. Source: How many stars are there in the universe? – Sky & Telescope

Winter on a small break

With all my errands this morning, I am surprised that I managed to get this walk/run (more walking than running right now) in today. I had to go though, because an arctic blast is headed our way, and I couldn’t pass up this day. Going to be cold for a few days after this. Overnight lows in the lower teens, day time highs in the twenties and thirties – cold. Not as bad as some though. All of those trapped by winter I am wishing you a lot of warm thoughts.

As a sidebar, unrelated to running – I read this great article this morning and I wanted to share it with you guys. I found it fascinating. You might too.

Here it is:

Scott Kelly has found an unusual way to maintain a youthful advantage over his twin brother Mark. Next month, he will blast off on a year-long mission on board the International Space Station, a journey that will have one unintended consequence. During his 12 months in space, Scott will age less than his earthbound brother – thanks to the tenets of Einstein’s theories of relativity.

“The effect is known as the twin paradox, though it is not actually a paradox, it is a straightforward consequence of the laws of relativity,” says Mark, who has also flown on several space missions including two as a space shuttle commander. “Essentially, time will pass slightly more slowly for Scott than for me because he will be travelling at a greater speed relative to me.”
