Are all atoms the same in an element? Yes, all things are made of atoms, and all atoms are made of the same three basic particles – protons, neutrons, and electrons. But, all atoms are not the same. You know that the number of protons in an atom determines what element you have. What property […]

How many alternate universes are there? One obvious question that arises, then, is exactly how many of these parallel universes might there be. In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16. How many universes are there in […]

Why did NASA stop using space shuttles? In 2004, President Bush gave a speech that outlined the end of the shuttle era, without clearly identifying what would come next (or how much it would cost).
