Compare and contrast The Solar Nebula Hypothesis and The Big Bang theory.​

Answer:

The Nebular Hypothesis is an explanation for the formation of solar systems. The Big Bang Theory explains the origins of this universe.

Explanation:

Chalk and cheese.

COMPARISON:

1) there is no comparison as they refer to radically different things:

2) The nebular theory refers to the solar system.

The Big Bang refers to the universe as a whole.

CONTRAST:

To put the difference between the solar system and the universe in context, the solar system is measured in astronomical units (AU), the universe in billions of light years.

An AU is the distance between the sun ☀️ and earth . It takes light about 8 minutes to cover 1 AU.

A light year is the distance that light will travel in a year. So, there are about 63241 AUs in a light year.

To put that in context, Pluto (on average) is a mere 40 AUs from the sun.

The nearest star to the sun is Proxima Centauri that is 4.24 light years away. The centre of the Milky Way (our galaxy) is about 30,000 light years away. Andromeda, the nearest spiral galaxy to the Milky Way, is 2.5 MILLION light years away. The size of the observable universe is 93 BILLION light years. You get the drift.

So, the nebular theory refers to what amounts to a spec of sand on a beach when compared to what the Big Bang theory explains.

WHAT THEY HAVE IN COMMON:

They are both scientific descriptions of how something evolved into what we observe today from given initial conditions.

Neither of them explains these initial conditions
