Some common questions about science are simple questions such as: "Why is the sky blue?" "How much does the Earth weigh?" and "How do airplanes stay up?" These were all questions that parents, in a survey for LiveWire, reported that their children had asked them at some point in time.
According to TheGuardian.com, adults have more complex questions and look to science for the answers. Such questions are:
"What is the universe made of?"
"Are we alone in the universe?"
"What is consciousness?"
"What makes us human?"
and "What is at the bottom of a black hole?"
Some of these questions already have scientific answers that are widely accepted. Some questions are topics of fierce debate, such as the question of what consciousness consists of. Most answers are still only theories without absolutely proof.
