Do you know who you are talking to?

THIS IS PART OF A TEXT IN PORTUGUESE OF MARIO SERGIO CORTELLA

Today, in quantum physics, we do not speak about the universe, but in the multiverse. The assumption that there is only one universe has no more place in physics. Science talks about multiverse and we are in one of the possible universes.

They say that 15 billion years ago, there was a large atomic explosion, which generated an incredible acceleration of matter and energy release. This feature was added forming what we humans call the stars and they came together, forming what we call galaxies. Science estimates that there are in our universe about 200 billion galaxies. One of them is our own, the Milky Way. By the way, nor is such a large galaxy; it is estimated that it has about 100 billion stars. So we are in a galaxy, which is one of 200 billion galaxies, one of the possible universes and it will disappear.

In this our galaxy full of stars, one of them is that now called dwarf star, the sun. Around this little star turn some planetary masses without own light, nine in all, maybe eight. The third of them from the sun is the Earth. What is the Earth?

The Earth is a small planet that revolves throne of a small star, which is one of 100 billion stars that make up a galaxy, which is one among other 200 billion galaxies in one of the possible universes and it will disappear. See how important we are ...

In this little place has a thing called life. Science estimates that on our planet there are over thirty million species of life, but so far only ranked around three million species. One is our: homo sapiens. Which is one of three million species already classified, who lives in a small planet that revolves throne of a little star, which is one of 100 billion stars that make up a galaxy, which is one among other 200 billion galaxies in one of the possible universes and that will disappear?

This species has, in 2007, approximately 6.4 billion people. One of them is you.

YOU are one among 6.4 billion individuals belonging to a single species, among other 3 million classified species, living in a small planet, which revolves throne of a small star, which is one of 100 billion stars that make up a galaxy which is one among other 200 billion galaxies in one of the possible universes and it will disappear...

That's why every time in life that someone asks me, "Do you know who you're talking to?," I reply, "Do you have time"?
