Question:
Why are there stars?


Replies:
Good question. Matter attracts itself to other matter. So stuff collects in blobs. If the blobs contain nuclei that can be transformed into more stable nuclei and give off energy, then a star is formed. The star "burns" the little nuclei of hydrogen and makes helium. The energy that is left over makes starlight.
