The cute picture above gives a basic example of what the doppler effect is: as a sound approaches a stationary listener the pitch of the sound is higher. As the sound passes the observer and moves away, the pitch of the sound becomes lower. You've probably heard this if you have ever stood nearby an approaching train or ambulance. Here is where it gets interesting: the doppler effect disproves the round earth. Think about it: the round earth (including the atmosphere) is supposedly spinning at 1000mph. [b]The direction of rotation is from west to east.[/b] That means the atmosphere [i]must[/i] be circulating with the earth from west to east. The speed of sound is 767mph. Remember: sound travels through a medium (in our case, air) and cannot travel where there is no material to move through. So the earth and you are each moving at the breakneck speed of 1000mph. Imagine you are standing facing west and someone half a mile away lights a firecracker. If the earth is really spinning at 1000mph, and sound only moves through the atmosphere at 767mph, you would NEVER be able to hear the sound of the firecracker exploding. [i]The sound would never catch up with you.[/i] When you see a lightening strike in the west, you should never be able to hear thunder if the earth is round and spinning as spherists claim. This shows that the earth really is Flat. I encourage you to put on your proverbial caps and think away. The earth is NOT round. I will be streaming live this Saturday at 8pm eastern time.

Or any other Flat earth question. When you open your mind, you will find that Planar Theory kicks ball belief every time... [spoiler]I'll be playing Black Ops 3 on xbone during my stream this Saturday. If anyone would like to play with me, let me know. I'll probably be playing Hardcore...[/spoiler]
