Alliteration: Alliteration is a special case of consonance and refers to the repetition of consonant sounds or blends at the beginning of words or in the stressed syllables of a line. Since consonance may happen anywhere in a word, the concepts are related but not identical.
How Old is the Solar System? How old is the Solar System? That is a question that cuts to the heart of it all. By studying several things, mostly meteorites, and using radioactive dating techniques, specifically looking at daughter isotopes, scientists have determined that the Solar System is 4.6 billion years old.
The problem is that this is an explanation based on zero observations and the assumption that the solar system is 4.5 billion years old. This is not a valid scientific model although it is accepted by most scientists as âthe way it must be.â Comets confirm a young universe, not an imaginary cloud in the sky.
