Did you know you could be right next to someone in outer space, screaming at the top of your lungs, and that person wouldn’t hear you?
Now that’s the sound of silence and It’s not just because space helmets are well insulated, it is because voices travel as sound waves. And sound waves need something to travel on, like the atmosphere around the Earth. There’s no atmosphere in space, so there is now way to transmit the sound waves. So astronauts have to communicate with each other using a specialized kind of radio wave. A radio frequency which doesn’t require atmosphere to carry them allows sound to travel in a vacuum.
Thankfully, God doesn’t need sound waves, or even radio waves to hear us. That’s because prayer carries our voices to God. So, if God who created the entire universe is ready to listen to whatever we have to say, that’s an exciting reason to pray more often.
