Our entire universe emerged from a point smaller than a single atom. Space itself exploded in a cosmic fire, launching the expansion of the universe and giving birth to all the energy and all the matter we know today. I know that sounds crazy, but there’s strong observational evidence to support the Big Bang theory. And it includes the amount of helium in the cosmos and the glow of radio waves left over from the explosion.

Apart from the obvious advantages of having ice to melt, filter, then drink, you can also break apart the water's hydrogen from its oxygen. Use the hydrogen and some of the oxygen as active ingredients in rocket fuel and keep the rest of the oxygen for breathing. And in your spare time between space missions, you can always go ice skating on the frozen lake created with the extracted water.

I never got into 'Star Wars.' Maybe because they made no attempt to portray real physics. At all.

For centuries, magicians have intuitively taken advantage of the inner workings of our brains.

There's an old saying in the space community: 'If God wanted us to be a spacefaring species, he would have given us a moon'.

Our nation is turning into an idiocracy.
