I am a cosmic astrophysicist.
(Cheers) (Applause)
thank you.
But I will be the first to tell you that I have invented this title.
(Laughter)
You see, I had to invent a title that describes what I do.
I got my doctorate in astrophysics,
Because I study the properties of stars near the sun.
But I also study planets and how they interact with stars.
Until 25 years ago, the term “planet world”
It is about people studying planets in our solar system.
But in 1992, the first planet outside our solar system,
Or the first outer planet, was discovered.
Therefore, there is no name for those who study what I study,
Today there are 3593 known outside planets.
(Shouts of astonishment)
That’s a lot.
So my field of work is still fresh.
If he is a person, he is barely of the age allowed to drink alcohol.
(Laughter)
While astronomy in general, which is the study of celestial bodies,
It has existed for thousands of years,
He is the oldest of the natural sciences.
So today we learn only
From all the potentially crazy planets in space.
There are some planets that share a star,
It has two stars for the same planet.
There is something similar in this picture,
Where it is very close to its star, so that its session is ten hours.
Earth cycle 365 days.
So this is crazy.
So we are now just beginning to understand
All physical and engineering properties are exotic
Which exist between the star and the planet.
But I do not just look at the movement of the star and the planet
For each other.
I study the chemical interaction between them.
Let me clarify.
Since the Big Bang, the only elements that existed were hydrogen and helium.
There was no carbon, oxygen, and iron.
There was none.
Then the big bang happened,
Then there was hydrogen and helium moving around the universe,
But it happened unevenly,
Even formed giant pockets of gas,
Which looks like what you see in the video somewhat,
In the end this gas collapsed on itself forming stars.
But these stars were very giant,
It was thousands of times larger than the sun.
(Laughter)
This is like saying that our sun is a grape, and the giant stars are the cat.
(Laughter)
Except that it is less fluffy.
But in these primary stars it was possible to exist
Temperature and density are sufficient to melt.
So for the first time elements were formed and clashed together.
We had hydrogen with one proton,
Helium contains proton,
Then join together, the lithium is formed suddenly,
Then beryllium, then carbon.
But these primary stars lived hard and died quickly,
It exploded everywhere.
And took all these new elements that formed within them,
It was launched into the universe.
And then form a second generation of stars mostly hydrogen and helium,
But also of those carbon molecules
Where the fusion process was completed.
The periodic table is sorted by stars,
Who lived and died at different times.
This table here is color coded and made by my colleague (Jennifer Johnson)
What she did was that she had colored symbols
To show the different ways in which these elements were formed.
You see that the little ones are blue because they came from the Big Bang,
But most come
Either of the two stars revolve around each other and then explode,
Or just one star exploding like a great dreamer.
So our sun has been formed of hydrogen and helium from the big bang,
But also of many of these elements.
At the same time that the sun was formed, planets were also formed.
Everything from Mercury to Neptune,
As well as Pluto the Dwarf.
But only on the ground flourished life,
It was from this life that humanity emerged.
But our humanity is truly rooted in the characteristics of our planet.
So when you think about it, people are made up of raw materials,
These elements are essential to life, formed in the soles of the stars.
We are carbon-based beings, we have bones made of calcium.
We walk on the iron silicate on the floor,
We breathe oxygen,
As you breathe now,
I can see it.
(Laughter)
Which came from a star.
So all of us are star dust,
Literally.
But we can also do something similar to other stars,
It is the production of other elements.
[Tennysin]
(Applause) (Cheers)
For example, tannisin, which you may have heard or not heard.
This is Tennysen 117, and was named after the state of “Tennessee”
Because a number of Vanderbilt scientists were members of the discovery team.
Usually my question is:
“How do you look at outer space?
While there are many problems here on earth?
Does not that make you feel small? “
My answer to this question is always no.
That does not make me feel diminished, but gives me the feeling of power.
Because I know all things, all events
Which may have occurred,
All the events that fall contribute to the life industry.
You see, it is important for us as human beings to know where we came from,
Whether our parents, our forefathers, our planet, or our mother star,
Or stellar incubator.
Knowing our roots is an important engine in our lives.
Using the scientific method
That we can develop a hypothesis
Can explain how the solar system exists in its current location.
For example, it is now believed that a greater mystery has exploded
4.6 billion years ago during the formation of the solar system.
We can then collect data on nearby stars and planets
So that we can understand its basic properties.
We have found certain elements in meteorites,
Also at the bottom of the ocean,
It can only be formed in a greater velocity.
In addition, with the help of our peers in reviewing the data,
We can really deduce
That this supernova worked as a big mixer,
Where taking gas, dust, all new items,
And blending them together until something is done
Good for life.
Given the thousands of planets,
Millions of stars,
We can see the combination of unique elements needed
To form a planet for life.
Then there were other unique circumstances needed
To form this life.
In other words, we are an athlete’s anomaly,
And something rare in the universe.
While there is a potential life in the universe,
Perhaps even in our Milky Way galaxy,
This life will be different from our lives,
Because they were affected by events that did not happen to us.
Will take time to find this life,
Because we need the ability to finance and develop technology.
So thinking about the possibility of our existence,
Do not make me feel meager,
It reminds me of all the possibilities in outer space.
When we were students we walked at night from the library to the dormitory,
And look at the stars.
I was looking at the constellation of the mighty.
We learned in our lessons that two stars move in space,
Often they will not collide under any circumstance.
And that the interior of the star has the structure of the bulb,
It consists of layers.
So with time, I realized that these constellations
Has changed from being just a dot in the sky to becoming entities with unique features.
I can see them on different dimensions of us,
They wear different colors,
They move at different speeds.
Some have very close planets,
It is hard to find out.
Some of them share a match with another star.
When you look at the sky,
It is like a climb from Earth to space.
Except, that instead of seeing data or images,
You see questions and possibilities.
Regularly looking outside our world,
It gives you an easy-to-forget impression.
There were many events that should fall
In order to be here today.
If one is different, for example, if the Earth were closer to the sun,
Or that the moon does not exist, life may not have evolved.
Recognizing the statistical possibilities of our existence,
Helps to endure the hardships of life,
It disturbs anxiety, feeling insecure.
And remind you of your identity.
Mathematical abnormalities in the gas cloud, stars, and planets.
What I’m doing is studying these stars and planets to try to understand
How they are shaped and developed.
Perhaps to discover a life.
But you do not need to be cosmic astrophysicists
So that you will feel inspired and powerful from outer space.
Just look at the top and remember that a lot of things happen
Outside of this time and place.
There are no breed stars,
Planets collide,
Rotating galaxies,
All of them are beautiful as you can see.
They have nothing to do with us.
(Laughter)
Or so you think.
But these are the events that should have occurred
In order to form the Milky Way Galaxy,
In order to explode a great revolution,
In order to rotate the earth around the sun,
In order to be created.
thank you.
(Applause) (Cheers)
