Chapter 910: The fermi paradox (1) (1/2)

For a moment Peter was speechless.

Then Peter tries to think about it and then he nodded but his expression was that he is not quite sure.

If Loki ask this to his other avatar, they might not know. But Peter, at least the Number Seven had learn many knowledge on many libraries all across the Omniverse. He even had read all the books in the Librarian Study Room

The Librarian had all the books ever written on Earth. Of course, right now that Librarian is not yet even born.

But Loki knows what is Fermi Paradox is. It took him for a few second but the knowledge comes naturally to him

When people look at the sky, they would sometimes be awed by the starry skies and the vast open space up there.

Or they would felt struck by the epic beauty or blow away by the insane scale of the Universe that seems limitless.

They felt their own smallness when they saw the sky. It felt like they were ants and the space is the sky inside a well

Everyone felt something when the look at the sky.

But the person who created the Fermi Paradox, physicists Enrico Fermi probably ask the sky

”Where is everybody?'

And everybody means other beings that might exist in the vast galaxy.

The starry sky seems vast but most people that did not have the ability to fly outside the Milky Way, they would only be able to see the stars of the Milky Way galaxy

The starry sky is vaster than any human could think off. It is so vast that trying to visualize it is a hard task

On the very best nights, when the clouds did not cover the sky, when no dust is able to cloud the sky, normal humans can see up to about two thousand stars in the sky

This is roughly one hundred-millionth of the stars in the Milky Way galaxy and almost all of them are less than a thousand light year away from Earth, or one percent of the diameter of the Milky Way.

Humans are limited in their understanding of the vastness of the galaxy. Peter was thinking deeply and Loki who was looking at his disciple did not disturb his disciple.

he knew that his disciple is trying to find the information in his mind.

It is not surprising for Loki to see his disciple having so hard a time trying to dig out one memory. This is because how deep Peter hide his memories inside his consciousness.

Inside Peter mind right now, he is slowly refreshing back his knowledge about Fermi Paradox.

Fermi Paradox is not about the size of the Universe, or how many stars we could see in the starry skies of the night

Instead it is related to a question that have tantalizes most humans which is ”Is there other intelligent life out there?”

As many stars as there are in the Milky Way galaxy, there is roughly an equal number of galaxies in the observable universe.

So, for every star in the colossal Milky Way, there is a whole galaxy out there

Altogether, that comes to the typically quoted range of between ten and ten total stars, which means incredibly for every grain of sand on every beach on Earth, there are ten thousand stars out there

After many calculations, roughly it could suggest that there is a potentially-habitable Earth like planet orbiting at least one percent of the total stars in the Universe, which translate to a total of one hundred billion Earth like planets

In other words, one could think of it like there is one hundred Earth-like planets for every grain of sand in the world

That is a lot of worlds

Of course, Peter knows that aliens do exist and some of them are quiet similar to humans and some of them are completely different.

There are many stars and there are many lifeforms

Whatever the case was, alien exist.

At least, that answer the question of where is everybody. But Fermi Paradox is not only about where is everybody up in the sky.

It relates heavily to another question. Because there are actually three theories about the Fermi Paradox.

Let assume that after billions of years in existence, one percent of Earth-like planets develop life, which if it's true, every grain of sand would represent one planet with life on it
