Is the Universe Shrinking or Expanding
The Universe is weird.
The Universe is nothing but stars, planets, galaxies, nebulaes, atoms and dust. When the Big Bang started about 5 billion years ago massive amounts of energy was released into the space. Atoms formed and it became more complex until it turned into rocks. Later the Sun formed from the energy of the Big Bang. The gravitational pull of teh Sun attracted the rocks and they crashed into each other.
As they collided they got stuck together and the rocks became bigger and bigger. The pressure inside the rocks was so high the rocks in the insde melted. The core was formed and the Earth was formed. Volcanoes started to erupt and the gases that came out of them turned into the atmosphere. It was mostly consists of nitrogen and later on alge and bateria formed. The algea absorbed the carbon dioxide from the volcanoes and turned it into oxygen. Life on Earth began to flourish.
Today astronomers all over the world study the other galaxies. Even the Hubble Space Telescope can only see a tiny fraction of the universe. Scientists say that everyday the universe is getting a little bit bigger. In about a few million years later they predicted it will shrink and this event will be called the “Big Crunch”. Everything in the universe will be gone.
Here are some pictures of awesome nebulaes I like:

You don’t get something from nothing. 0+0=0 Having nothing collide with nothing equals nothing. So therefore your big bang theory is disproved.

well you explain it sherlock?

The fact is, Bob, that “nothing developing something” or “something coming from nothing” (however you want to word it) defies the laws of thermodynamics, physics, etc… Something had to exist prior to the “Big Bang”

i think the universe is an odd concept but yet amazing, there are all these amazing things we know and have seen of our galaxy but yet so much more to explore, who knows whats out there, there might even be another life form, and as for your statement ‘Debunker’ it doesn’t matter how it started because it’s all ready here and we just need to explore as well as not damaging it, take Earth for instance, we need to look after that other wise it will perish along with all the others planets and matter we destroy.
