Currently, one of the most accepted theories as to the origin of our solar system is this:

1. a "big bang" expansion of protoplasmic phenomena

2. coalescence of this cosmic "soup" into stars after some thousands, millions, even billions of years (approximately) 

3. remnants of supernova star explosions reforming into planets and moons

4. abiogenesis, life beginning amidst, from inanimate matter, upon Gaia


"Gaia is a beautiful name of Greek origin for these earths and waters. In Greek mythology, Gaia, known as the mother goddess, was the personification of the Earth. She is described as a caring and nurturing figure to all the children and plants of the world." (from a Google search for the word "Gaia")


seeming evidence for this includes:

  • the "red shift" of galaxies observed thanks to the Hubble space telescope

  • same fossil remains on the east coast of South America and the west coast of Africa indicating "Pangea" existed, all continents,including these being together at once in the past

  • seeing such as below, the apparent remnants of supernova explosions

According to a video lecture by a professor I saw upon the topic of abiogenesis, approximately 10^55 (a one with fifty-five zeros after it) combinations of chemicals, substances existed on early Earth which yielded the basics of life.

Eventually into the thousands of types of species came to be upon Gaia, this planet, over eons.

Some seemingly possible dangers to the continued existence of life like we know it include:


We likely lack the ability to stop such things if too large and dangerous.

I hope I become wrong about this soon rather than later and that we become robustly safe amidst the galactic cosmos.
