Astronauts appear weightless while in orbit around Earth because the space shuttle and the astronauts are in free fall around it. Since they fall at the same rate as the space shuttle, the astronauts appear weightless.</span>

2. A hypothesis is an educated guess based upon observation. It is an explanation of a single event based upon what is observed.
uranmaximum [27]

A law is supported by scientific evidence that is reproducible, whereas a hypothesis is simply a guess that can be confirmed or refuted by an experiment.

<h3>What exactly is a hypothesis?</h3>

A hypothesis is a guess based on a large amount of background information. If only five trees survived, they may have received more light than the other five.

In that case, one will devise an experiment in which the same plant is randomly assigned to different treatment groups with varying degrees of light, and the rate of growth of each group is compared.

Thus, a law is supported by scientific evidence that is reproducible, whereas a hypothesis is simply a guess that can be confirmed or refuted by an experiment.
