The universe and the solar system - part 2

The video explains the Crossing Star Theory by Chamberlain and Maltin, which suggests that the solar system originated from a large star, the sun. Another massive star approached, causing an expansion and explosion of part of the sun, forming a gaseous line. This line condensed and cooled, eventually forming the planets.

Who proposed the Crossing Star Theory?

• Hawking and Sagan

• Chamberlain and Maltin

• Newton and Einstein

• Galileo and Copernicus

What was the initial assumption about the solar system in the Crossing Star Theory?

• It was originally a big star, the sun.

• It was a black hole.

• It was a large planet.

• It was a collection of small stars.

What happened when another massive star approached the sun?

• The sun's surface facing the star expanded.

• The sun shrank in size.

• The sun turned into a black hole.

• The sun moved away from the star.

What was formed after the expansion of the sun's surface?

• A liquid stream.

• A magnetic field.

• A solid line of rocks.

• A gaseous line.

How did the planets form according to the Crossing Star Theory?

• By the collision of asteroids.

• By the evaporation of a liquid line.

• By the cooling and condensation of a gaseous line.

• By the fusion of smaller stars.
