Much of modern physics has been about exploring inherently invisible things, which seem to be far more common than the obvious things we experience with our senses. Yet these invisible things follow rigorous laws that allow us to test their existence in many ways. Here is a very short list of some of the "invisible" things that we routinely work with.
If good things really do come in threes, then Valencia -- Spain's third-largest city after Madrid and Barcelona -- perfectly completes the trifecta.
While it may be disappointing, I have to confess to people who ask for my insights on the meaning of it all that astronomy doesn't provide any clearly useful data on matters of sin and souls. But it does offer some humbling insight into the scale of the problem.
We all know you can freeze juice or fruit -- but what about alcohol?
We may actually be of the utmost significance to the universe, because after nearly 14 billion years of cosmic evolution, it is through our brain power that the universe has finally achieved self-awareness.
This week the International Dark-Sky Association (IDA), astronomy clubs, and a host of U.S. national parks across the country celebrate International Dark Sky Week to raise awareness of light pollution.
It is time and then some to move on to the pleasures of spring.

"Maybe I expected more or maybe I expected the experience to be more memorable after almost one year waiting for the meal. I think it's become some sort of celebrity thing and a place where you should go if you get the chance, no matter how and that it has to be good."
The plagues are a parable. Those who build empires on oppression, who defy divine directives of righteousness, will ultimately find their own lives unlivable. Nature is the agent of this cosmic comeuppance.
I've watched the new incarnation of Cosmos with a sharp eye, for several reasons. When I was young, I was one of those who knew Carl Sagan, and I was materially influenced in my career path by him. I am very impressed with the job that the new Cosmos team has done.
Imagine a novel that starts like this: A speck of space imbued with a mysterious antigravity substance explodes to humongous size in a tiny fraction of a second and transforms into an entire universe. Sounds ridiculous, right? And yet most cosmologists believe this is how the Big Bang began.
Backyard astronomers, get ready to feast your eyes on the skies. In April the red planet returns to prime time, and the Moon shows us a darker side.
