00:00So, you are completely alone in space, and you are able to reach out to the help of the audience.
00:05So, it's not that there is no noise.
00:09Yes, in space, there is no sound travel.
00:12Look, sound actually travel is in waves.
00:15And in waves, you need a medium, like water, water, water, or a solid surface.
00:22When you say it, your voice is in vibrations.
00:25And those vibrations are in other people's hands.
00:28And when you say it, your voice is in the air.
00:30You can hear it.
00:31The wind is in air, so we can hear it.
00:34But in space, there is vacuum.
00:36That means, there is no wind, no medium.
00:39And if it's not medium, then how will sound waves travel?
00:42So, in space, you can't even hear it.
00:45It will be a sunnata.
