The correct response is:
The solar system formed about 9 billion years after the big bang.
The solar system is believed to have formed from the gravitational collapse of matter within a large molecular cloud about 4.6 billion years ago, which is approximately 9 billion years after the big bang that created the universe.
None of the statements accurately reflect the heliocentric model of the universe, but the closest to a correct interpretation in terms of the solar system would be:
The sun is located at the center of the universe.
However, it's important to clarify that in the heliocentric model, the sun is at the center of the solar system, not the universe. The universe contains billions of galaxies and is not structured around our solar system.
The statement that best represents the main idea of the geocentric model of the universe is:
Earth is the center of the universe.
In the geocentric model, which is an ancient belief system, all celestial bodies, including the sun, moon, and stars, are thought to revolve around the Earth.
The statement that best describes the movement of galaxies in the universe is:
Galaxies are moving away from each other, with galaxies farther away moving faster.
This observation is a key concept in cosmology, known as Hubble's Law, which states that the recessional velocity of galaxies is proportional to their distance from us: the farther away a galaxy is, the faster it is moving away.
