They jump around, it happen once to me.
The earth is falling. It takes the earth an entire year to fall once around the sun.
If everyone on Earth jumped at once, the impact would be very small and not noticeable. The Earth is so massive that the force of all the people jumping would be insignificant compared to the planet's size and mass. The Earth would not move or be affected in any significant way.
Once the moon has passed by, in between the earth and the sun.

skydive, fly, get married, bungee jump, gamble
Yes, Acid or LSD etc, have known it to happen twice, once fatal once luckily not. Not sure if this is the info your looking for though.
Everyone on Earth died at least once
People once believed the earth was flat. But clearly it is not. People once believed the earth was the center of the universe and that it was held up or sat on the back of a tortoise (or creature of some sort) that also turned out not to be true~
People once believed the Earth was flat because it appeared that way to the naked eye. Travel and exploration were limited, so many individuals did not have access to evidence proving otherwise.
Earth blocks the moon from getting any of the Sun's light. So it happens only once in awhile.
You cannot jump twice in Transformice, however you can jump in the middle of the air. This is called "air jumping" This can be done by leaving a platform, not by jumping off it but simply by walking off it. This allows you to jump once in the air. For everytime you have contact with an object or platform in gains you the ability to jump once.
