“The world owes you nothing. It was here first.” -Mark Twain When you think about where all of this came from — back to the beginning of the Universe — there’s a good chance it makes you a little uncomfortable. For this week’s Ask Ethan, our one remaining column here on ScienceBlogs, our reader vvv…

“Some say the world will end in fire, Some say in ice. From what I’ve tasted of desire I hold with those who favor fire. But if it had to perish twice, I think I know enough of hate To say that for destruction ice Is also great And would suffice.” -Robert Frost Depending on…

Ask Ethan #13: Where does matter come from?

“One of the most tragic things I know about human nature is that all of us tend to put off living. We are all dreaming of some magical rose garden over the horizon instead of enjoying the roses that are blooming outside our windows today.” -Dale Carnegie Our new Ask Ethan segment has been really…

Ask Ethan #4: Weird Astronomy Maps

“I have an existential map. It has ‘You are here’ written all over it.” -Steven Wright So just because the Ask Ethan series is becoming way more popular than I can handle — I’ve got more than 200 questions that I’m sitting on by now — doesn’t mean you should stop sending your questions! There…

“We are not simply in the universe, we are part of it. We are born from it.” -Neil deGrasse Tyson The story of the Universe is the story of us all; we all share the same cosmic history, coming from a hot, dense state some 13.8 billion years ago known as the Big Bang and…

“These neutrino observations are so exciting and significant that I think we’re about to see the birth of an entirely new branch of astronomy: neutrino astronomy.” -John Bahcall You’ve been around here long enough to know about the Big Bang. The vast majority of galaxies are speeding away from us, but more than that, the…

The Dark Depths of the Universe

“By denying scientific principles, one can maintain any paradox.” -Galileo Galilei Day and night.

While the Earth spins on its axis, orbiting the Sun, roughly half of our lives are spent bathed…
