"Anything only exists because we think why it doesn't exist"
"All theorems are true until proven wrong"

You need the ability of reason to question something. The earth till date would have been considered flat if someone wouldn't have thought otherwise. We are finding more and more bizarre things in our search and yearn to understand this universe. Even though the discoveries are afresh, but the subject of discovery has been in existence since time. The universe will allow us to observe itself until we keep looking, the day we stop, it will freeze its own existence and state.

Language came into existence because we needed ways to communicate. Take up any random word and think why somebody would have felt the need to coin it?

As we keep imagining and exploring, the universe unravels itself. In your day to day life, I don't think the black hole sitting in the center of our galaxy has any direct impact. you will be indifferent to its existence.
But its there now since somebody has observed it. If nobody would have, it might or might not have existed?

All of these thoughts intrigue me a lot. What do you think?
