Noticing the sky is dark and hearing thunder in the distance are examples of observations.
The width of thunder is the distance between your left and your right eard drums.
There is a delay between seeing the lightning and hearing the thunder because the speed of light (lightning) is much faster than the speed of sound (thunder). Thus, you SEE lightning first, and then you HEAR thunder later.
Thunder is what you hear, lightning is what you see, but both are due to electrical discharge in the atmosphere. They can seem to be separated in time to an observer (you see the lightening before you hear the thunder) because of the large difference in the speed of sound and the speed of light. If you are significant distance away (a few miles or kilometers), the light from the discharge will reach you almost instantly, but the sound can take several seconds to arrive. In fact you can measure the distance from you to the lightening in this way: for each second delay between seeing it and hearing it, the lightening bolt is approximately 300 meters, or 1000 ft away. Thunder is merely the rumbling sound that lightning creates. You hear the thunder after you see the lighting because light travels faster than sound. Lightning is the light that is emitted, and thunder is the sound.
When lightning appears in the remote distance and appears to produce no thunder sound, it is popularly known as "heat lightning." Meteorologists will tell you that there really is no such thing as a distinct type of lightning that is not followed by thunder. All lightning produces thunder, but it is only audible for a distance of some 15-20 miles from the storm. At night, lightning can be seen for distances of up to 125 miles if the conditions are right. So when lightning is seen but no thunder is heard, you are simply too far away from the storm.
roughly a mile
Of course it can, hearing thunder after it rains means you are hearing the storm roll away, or a new one is coming.
you are probably hearing the thunder from a different lightning strike.
It still produces thunder - however... the further the sound wave travels through the air, the more it weakens. If you're a long way from the storm - chances are the sound of the thunder will have dissipated before it gets to you.
Thunder will not cause blindness, it may cause hearing damage if the lightning strike is very close.
