Dark energy is incredibly strange, but actually it makes sense to me that it went unnoticed, because dark energy has no effect on daily life, or even inside our solar system.

We're going to understand that there is life on other bodies in the solar system.

Mars is the only place in the solar system where it's possible for life to become multi-planetarian.

There's life all over this universe, but the only life in the solar system is on earth, and in the whole universe we are the only men.

The planets and moons of our solar system are blatantly visible because they reflect sunlight. Without the nearby Sun, these planets would be cryptic and dark on the sky.

We know there is gravity because apples fall from trees. We can observe gravity in daily life. If we could throw an apple to the edge of the universe, we would observe it accelerating.
