Have you ever imagined?
Do you know people who turn to you and say:
"Do you know who you are speaking with?"
Some people don't even admit being stopped by the revolving door in banks
He thinks it's an offense
He almost turns to the guard and asks: "Can't you see I'm white?"
There are people who don't admit being stopped in Restricted Access
"Do you know who you are speaking with?"
What do you answer, huh?
I asked to place a projector here in order to draw what it means
When someone say "Do you know who you are speaking with"
what should you answer?
What is a 'Human being'?
What could a 'Human being' be?
What is a man?
What is a woman?
If you want to keep the light for the sake of filming, feel free, ok?
It won't disturb here, it's the problem of... that's good.
Look at this...
What is a 'Human being', huh?
Aristotle said, in the fourth century b. c., that man is a rational animal.
We've used this so far.
Man is a rational animal.
Pascal said in the seventeenth century,
"Man is a thinking reed"
Can you imagine?
Fernando Pessoa has the definition of 'human being' I like the most.
Fernando Pessoa used to say that the man is a delayed corpse.
Man is a delayed corpse.
His definition is quite precise.
What is a 'human being'?
Science has had some suspicions
and I'd like to take a quick trip here just so you don't miss it.
Science believes we are in a universe
which probably has a cylindrical shape
due to the curvature of space.
Up to some years ago this theory was considered the only one.
Nowadays one suspects it may not be so.
However, one believes we are in a universe which has a cylindrical shape
due to the curvature of space
and which is, attention, one of the possible universes.
Quantum physics, that will prevail from now on,
doesn't work with the concept of universe anymore,
but with the notion of multiverse.
You just have to see Marcelo Gleiser's great books
and other studies carried on in this area
with a very good translation to a more common language
this will help us think.
Science believes we are in a universe which probably has a cylindrical shape
and also that this universe appeared approximately 15 billion years ago -
some say 13, others 18
but probably 15 billion years ago there was a big explosion
which a British scientis who died 5 years ago -
for mockery, because he didn't use to believe it -
called "Big ***" and the name stuck.
What is the scientific assumption
that 15 billion years ago our universe - all of it - was contained in a single spot?!
This is the logic, look at my hand here:
you take a metal ball and keep gripping, gripping, gripping
when you get a maximum grip
you tie with a little string -
imagine the amount of concentrated matter and retained energy there...
15 billion years ago our whole universe was in a single densified spot
15 billion years ago, someone, something, God, I can't tell, cut the little string
and then it expanded.
When expanding, it expanded matter and unleashed energy.
Stay calm, we're still in expansion.
So, if you look at the sky tonight it's possible to observe the expansion of our hemisphere
compared to the sky last year.
If you have clarity.
And it's true, we are in expansion because the spring is still spreading.
By the way, I would like to remind you that the sky you have seen today is the sky of 2004.
Which is exactly the speed of starlight that is arriving here.
Never offer the sky to you beloved one.
This is 'our' sky because it can be someone else's.
It was the one of 2004.
The sky of now, of today, you will only see in 2010 in fact.
Well, 15 billion years ago there was a super speeded up expansion of matter and energy
and we are in expansion.
You will complete the course with me, right?
When the expansion of the spring reach the apex,
it will retract.
And after, it seems like this process is systolic and diastolic
such as our hearts.
Perhaps Earterners know it better
because they have religions who work with the idea of expanding and retracting -
the lung does this,
the heart does
it seems like the planet and life do this;
our brains expands and retracts..
it seems like there is a secret of life in the systolic and diastolic.
I don't know.
It's a matter of belief.
Anyway, there is this... don't worry, because science has already calculated
that this retracting will happen in 12 billion years.
By then you will be already retired according to the new rules
[incomprehensible]
Look! 15 billion years ago, there was a super speeded up expansion of matter and energy
this matter has concentrated in what we humans call 'stars'
and the stars have grouped in what we humans call galaxies.
"Galak" in Greek is 'milk'
Science calculates in our universe there are approximately 200 billion galaxies.
It's not 200 galaxies... it's 200 billion galaxies.
One of them is ours. It stays in the exit edge of the universe - it's Via Lactea
which is 'milk' in Latin.
And it's not such a big galaxy - it has only 100 billion stars.
One of these stars is ours,
when a child it was called a fifth-magnitude star.
Now it's called a dwarf star: it's the Sun.
What is the Sun?
The Sun is a little star among other 100 billion stars
compounding one galaxy among other 200 billion galaxies in one of the possible universes
which is going to disappear.
Planetary bodies with no light of their own revolve around this little star -
nine, to be more precise
maybe eight.
The third of them out from the Sun is the Earth.
What is the Earth?
The Earth is a little planet that revolves around a little star
which is one among other 100 billion stars
compounding a single galaxy among other 200 billion galaxies
in one of the possible universes
which is going to disappear.
See how important we are!
Some people think God made all this just so we could exist down here.
What an intelligent God
who understands of cost-benefit
he makes billions of stars and galaxies just so we exist here
Some people think worse things - they think God has created all this just for this person to exist here..
with the money he/she carries, the accent he/she uses, the religion he/she practices
with the position he/she occupies in the bank or in the university
with his/her skin color...
Have you ever imagined?
Science knows there is something called 'life' in this planet of ours
and it's funny that some people think there's life only here, because it's all so small
Science calculates in our little planet there is something around 30 million species
but so far it has only categorized 3 million species of different creatures.
One of them is ours, *** Sapiens
Our species is one among other 3 million already categorized species
that live in a little planet which revolves around a little star
which is one among other 100 billion stars compounding a single galaxy
among other 200 billion galaxies
in one of the possible universes
which is going to disappear.
This species in 2007 - that is the year we are in - has 6 billion 400 million individuals.
One of them is you.
Who are you?
You are one individual among other 6 billion 400 million individuals
compounding a single species among other 3 million of already categorized species
who live in a little planet which revolves around a little star
which is one among other 100 billion stars
compounding a single galaxy among other 200 billion galaxies
in one of the possible universes
which is going to disappear.
How about Romário?
No, not Romário. Romário is above. [famous soccer player]
Have you imagined? 6 billion.
Who are you?
Who am I?
Who am I to think that the only way to do things is the way I do?
Who am I to think the only proper color skin is the one I have?
Who am I to think the only good place to be born is the one where I was born?
Who am I to think the correct accent is the one I use?
Who am I to think the only correct religion is the one I practice?
Who am I? Who are you?
You are vice-thingy of sub-doodah.
That's why in my life, all the times when someone came to me and asked
"Do you know who you are speaking with?"
I answer like this, "Do you have time?
Have a sit."
