Suppose I fire off a radio signal, in all directions, into space. Conventionally we would imagine it as a continuous wavefront propagating through space. But when does it "break-up" into individual photons?

Suppose again that I was trying to contact a specific alien planet far away. If my radio signal breaks into individual photons then the angular coverage provided by the individual photons might not cover the planet I am attempting to contact! In which case the Aliens never hear my message of peace &or friendship & or demands for Oil drilling rights!

The thoery that life magically appeared is nonsense to me. Life cannot evolve from nothing or a bang somewhere in the universe nor can an imploding star create the never ending universe. How woudl it be possible for a single celled organism to create a brain or a heart or lungs and assign them a specific purpose! If there is no God then how did that organism get life? There is a God!

I just read that if humans can avoid killing each other in the next 100 years, we would be able to settle into other places in the universe, but wouldn't that make Christianity and many other religions null and void? How would we be able to beleive in anything if certain religious events happened on our home planet Earth? How would Jesus be able to come onto Earth if we have moved on? Doesn't it bother you that space settlement is possible but we'd be leaving our religious beleifs behind? How would we beleive in anything if we left our planet Earth? Wouldn't it be hard to beleive in an afterlife and a creator if we left the planet in which was created from the creator and the afterlife he gave us?

I think it is possible. But not traveling at the speed of light. I think there is another way of traveling thru time. We only use a very small part of our brain. If we could expand the use of our brain then we could travel thru time mentaly.

Most of you seem to be saying 'because they do!'-but would anyone be happy with the answer 'because it is!' to the question 'why is the sky blue?'
Thks Larry M for seeing the real question beyond the obvious.
To expand it further-
Since it is true that objects stay the same size regardless of their distance, is it fair to say that 'objects only look smaller - the greater the distance-due to the way the human brain organizes information, in order to allow the viewer to make sense of the world around them?'-Indeed if there existed a species which used sound as a primary method of observation-that their brains might not sort information in this way-and who might 'see' objects at great distance at 'full' size-generating a confusing mass of image and perspective, making their visual senses less usefull than hearing or touch? and while I understand the concept that less light reaches the observer-the greater the distance-why doesn't it result in a dimmer image rather than a smaller one?
