What was the first synthetic fiber invented?

Nylon was created in 1935 and became quite popular, explaining why there was a shortage during WWII.

What is Newton's first law of motion?

The first of Newton's laws states that nothing moves unless a force acts upon it. This can also be used to explain why it's hard to get up off the couch.

Which of these statements is true about gravity?

Even tiny things have gravity. An apple has gravity -- but a donut seems to have more of a gravitational pull.

What has a gravitational pull so strong that it pulls in light?

Black holes pull in light, thus their black color. Their gravitation pull is so strong that they literally suck everything up. We all know someone like this. . .

What creates the different colors of the rainbow?

The different wavelengths are what create different colors. In the visible spectrum, red has the longest wavelength and violet has the shortest.
