Explain why we see lightning before hearing thunder. Just please explain that.
Get this, he tried to claim that sound and light travel at the same speed and it's just our brain doesn't process the sound as quick as the light.
I pointed out that this would make conversations impossible, he ran away for a few pages but of course came back.
You simply cannot engage your own brain. It has to be set out for you by your mentors.
Have a think about your eyes and ears, then come back to the subject.
Okay wait, so If I see a very large explosion 1 km away and hear the sound only 3 seconds later, is that my brain telling me to not hear the explosion for 3 seconds now? but when a cracker explodes close to me it seems immediate. . . how does the set up between my eyes and ears make up that the further away the explosion the larger the difference between the visual and audio cues?
I didn't think I'd need to actually tell you or any other so called sensible person this. Let me try and see if it goes in one ear and out the other, or not. Pardon the pun.
Ok let's place this scenario for you.
You are stood next to a person who has a telescope and also has a hearing aid device.
He is looking into the distance with his telescope that he bought from you a few weeks earlier due to you never using it but pretending you do.
Anyway he shouts, "oi, manwolf did you see that explosion light up in the distance?2
You reply" no I didn't."
Can you guess why?
Anyway he hands you the scope the next day and you see an explosion of light whilst he is stood there with his hearing aid device rammed into his lug.
You say " did you see that explosion of light." He says: " no but I hear a rumble, can you hear it." You say: "No, I can't hear anything."
Can you guess why?
What relevance is this?
It has plenty if you are prepared to screw your head on.
