Summary

In this episode, we will answer listener questions that explore how the universe works in fun and surprising ways. We learn that nothing can travel faster than the speed of light and explore what might happen if we could—like time slowing down and strange space effects. We also find out that there are stars much bigger than the Sun, how the Sun spins on its axis and how gravity, though invisible, holds everything in place. We will wrap up by understanding why air remains invisible despite being all around us but can still be felt and experienced in many ways, like wind or when we breathe.

0:00.0	My name is Walter, and I live in Massachusetts, and you are listening to Sleep Tite Science.
0:20.5	Did you know that if you could travel at the speed of light, you could circle the earth 7.5 times in just one second?
0:31.5	What?
0:32.7	That's super fast.
0:34.5	That's super fast.
0:49.4	Hello, friends, and welcome back to sleep-tight science, a bedtime show that answers your questions about science.
0:52.7	In this episode, we're doing something a little different. Instead of science. In this episode, we're doing something a little different.
0:57.5	Instead of sticking to one specific topic,
1:01.0	we'll spend our time together answering your excellent questions about science
1:06.5	and the world around us.
1:08.7	You've sent in so many excellent questions that it's hard to answer them all.
1:15.1	But in this episode, we're focusing on the ones that explore how the universe works in fun and
1:22.5	surprising ways. Let's get started.
1:37.0	Our first question comes from Nida, who is seven years old and from Los Angeles, California.
1:45.0	She wants to know, what happens when you travel faster than the speed of light in space?
1:51.0	Nida, we did some reading and as it turns out, nothing can travel faster than the speed of light,
1:55.0	at least not according to the science we know today.
1:59.0	The speed of light is the ultimate speed limit in our universe.
2:06.1	Light travels at an incredibly fast, 299,792,458 meters per second. That's about 670 million miles per hour. And nothing with mass can go faster than that.
2:30.8	Scientists have spent a lot of time trying to understand why this is, and it all comes back to a theory created by Albert Einstein called relativity.
2:45.1	Einstein's theory of relativity tells us that as things move faster and get closer to the speed of light, weird things start to happen.
2:56.7	For example, time slows down for objects moving near the speed of light.
