what's the reason of a big object can not go through in a small hole? i guess, it is the distance between them and the elapsed time. because when the object is far away, it is as small as can go through in a small hole. but as long as the object approach the hole, namely, as long as it passes...
i know this is a primitive question and to be answered in my head. eventually both light and sound are a wave carrying information and energy. is speed of light effective to we see it?
i just ask my question out of all rules.this is just a think.if we can move at speed of light(assume),can we pass a little hole
for example how to fit these huge stars to our eyes,how can we see them
