Answer 1

$\huge\underbrace\mathcal\red{Answer}$

1. The Oort Cloud is a predicted collection of icy objects farther away than everything else in the solar system. It fits with observations of comets in the planetary region of the solar system, but scientists have yet to observe any object in the Oort Cloud itself
2. For starters, it spins in the opposite direction from most other planets, including Earth, so that on Venus the sun rises in the west.
3. If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse.
4. If the universe did begin with a rapid expansion, per the Big Bang theory, then life as we know it sprung from non-living things

Answer 2

Answer:

The Oort Cloud is a predicted collection of icy objects farther away than everything else in the solar system. It fits with observations of comets in the planetary region of the solar system, but scientists have yet to observe any object in the Oort Cloud itself

For starters, it spins in the opposite direction from most other planets, including Earth, so that on Venus the sun rises in the west.

If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse.

If the universe did begin with a rapid expansion, per the Big Bang theory, then life as we know it sprung from non-living things
