The zero-g plane allows for a lot of experiments to be conducted without the expense of getting equipment into orbit. Apparently 80% of microgravity research can be performed in a zero-gravity plane, which is much cheaper than going to space. The flame from the...

In interpreting space or aerial photos, it’s important to notice where the source of light is originating. Noticing the light source is what helps you determine whether an object is a depression like a bowl, or a projection above ground such as a mound or dome. Click...

An atom is mostly empty space, but empty space is mostly not empty. The reason it looks empty is because electrons and photons don’t interact with the stuff that is there, quark and gluon field fluctuations. It actually takes energy to clear out space and make a...

The big bang theory is the most accepted theory for the formation of the universe. The “big bang” is a misnomer because there was no explosion, but rather a rapid expansion. It is not known what existed the moment before the big bang, however the evolution of the...
