We put some satelllites in space in what's called
"The
Lagrangian points (
/ləˈɡrɑːndʒiən/; also
Lagrange points,
L-points, or
libration points) are the five positions in an
orbital configuration where a small object affected only by
gravity can theoretically be stationary relative to two larger objects (such as a
satellite with respect to the
Earth and
Moon)."

You can put something into orbit and it will remain stationary like in between the earth and the moon where the gravity of each balances each other out, basically.
The sun's gravity is massive and extents way out past Pluto even pass the Kuiper belt.

"What is the Big Bang theory?
The Big Bang theory says that the universe was very hot and concentrated in the distant past and, ever since then, space has been stretching and cooling. This is the only theory that successfully explains the observations made by astronomers."
"What happened before the Big Bang? What happened right at the moment of the Big Bang?
We don't know. To even address these questions we need to have a quantum theory of gravity. We have a quantum theory, and we have a gravity theory, but these two theories somehow need to be combined. We know that our current gravity theory does not apply to the conditions of the earliest moments of the Big Bang. This is exciting research now in progress!
- Was the Big Bang an explosion?
No, the Big Bang was not an explosion. We don't know what, exactly, happened in the earliest times, but it was not an explosion in the usual way that people picture explosions. There was not a bunch of debris that sprang out, whizzing out into the surrounding space. In fact, there was no surrounding space. There was no debris strewn outwards. Space itself has been stretching and carrying material with it.

The singluartiy is not so much a part of the big bang theory. An analogy would be abiogensis and evolution. Singularity and big bang.

One of the next processes is the first MASSIVE stars that formed. When they exploded it seeded the universe with the HEAVY ELEMENTS, like carbon, oxygen, gold, calcium, iron, and others. This provied the material for planets to form from gas and dust and rock. Our solar system is made from recyceled material from star dust.

How do
stars form and evolve?
Stars are the most widely recognized astronomical objects, and represent the most fundamental building blocks of galaxies.

We see stars and planets and solar systems being formed right now with the hubble space telescope and other x-ray and infared telescopes.
