Human lives generally last for 2 billion to 3 billion seconds; the universe is nearly 14 billion years old. Looking at those two statements on my laptop, I feel slightly giddy. I have a faint whiff of what the first statement means and very little understanding of the second. If you feel the same, here’s […]
Big Bang
Mirror Universes
For nearly 100 years, the idea of a “Big Bang” birthing our universe has been the leading cosmological model. In the 1920s, Russian mathematician Alexander Friedmann and later Belgian astronomer Georges Lemaître derived the notion of an expanding universe based on Einstein’s 1915 General Theory of Relativity. Extrapolating backwards in time, expansion implies an infinitely […]
The Universe: Whodunnit?
Cosmology is essentially a whodunnit but, unlike your typical 600-page detective yarn, this story doesn’t unfold clue by clue until the denouement in last few pages. The puzzle — basically, “How the hell can we explain our presence here?” — is more cryptic than ever. For all the thousands of brilliant minds working on the […]
Science. It Works, etc.
No stranger to controversy, evolutionary biologist Richard Dawkins (The Selfish Gene) invited it in spades during an appearance at Oxford University in February of 2013. Asked for evidence that scientific theory was valid, he responded, “[Science] works! Planes fly. Cars drive. Computers compute. If you base medicine on science, you cure people. If you base […]
Whispers from the Birth of the Universe

The irony is that they weren’t even looking for it, but they won Nobel Prizes anyway. […]
