The Big Bang: Origin and Expansion of the Universe

(According to the standard model of astronomical research)

View: Wikipedia >>>

 

The Big Bang and thus the beginning of the universe occurred approx. 13.8 billion years ago
(= 13 800 000 000 years) = age of the universe.

 

According to today’s knowledge, the entry of the universe into reality took place via “Planck’s parameters”:

 

Planck time: 10-43 seconds (1/10 000 000 000 000 000 000 000 000 000 000 000 000 000 000 sec)

Planck expansion: 10-33 cm (1/1 000 000 000 000 000 000 000 000 000 000 000 cm): „singularity“

Planck temperature: 1032° K (100 000 000 000 000 000 000 000 000 000 000 K)

 

Approx. 380,000 years after the Big Bang, the temperature of the universe had dropped to about 3000°K.

This enabled the use of light radiation, which still provides detailed information today. 

The objects in space that can be researched today as the most distant were then only about 40 million light years away from us.
(40 million light years = about 15 times the distance from our Milky Way to the nearest large Milky Way, the Andromeda Nebula)

 

The light emitted by these objects was stretched by the expansion of the universe
(at about 1 million km per second = more than three times the speed of light)
so that by the further expansion of the universe in the approximately 13.8 billion years that have passed since then, these objects are 46.6 billion light years away from us.

So this light is coming from 40 million light-years away, but the information it gives us comes from objects that are now 46.6 billion light-years away. But this light describes these objects as they appeared 13.8 billion years ago. We know nothing about the actual state of these objects. To a limited extent, however, calculations can be made about their further development.

 

Astronomers explore the past of the Universe 

Thus, astronomers are not only exploring the present of the universe, but above all its past. The further they penetrate into the depths of space, the further back they look into the past of space.

Even the nearest large galaxy, the Andromeda Nebula, cannot be studied for what is happening there now, but only for what happened there about 2.5 million years ago, because the light that provides us with information takes 2.5 million years to get from there to us.

So exploring the depths of space means exploring the history of space. We see the most distant objects what they looked like about 13.8 billion years ago.

 

About the speed of the expansion of the Universe 

The speed of light (approx. 300 000 km/sec) is a speed within space where no higher speed exists.
The speed by which space expands is to be considered as a kind of  "formation of space" and thus something completely different! (at about 1 million km per second = more than three times the speed of light)

The speed of space expansion was not always the same. Especially in the early phase of the universe, there was an extremely high speed of space expansion, which is called the "inflationary expansion phase".

There are signs that the speed of the expansion of the universe is increasing a little since a long time.

 

Comparison

The universe expands by about 87 billion km in one day.

The US Voyager rocket, which flew to the outer planets of the solar system, averaged 11 km per second. This rocket would need a good 200 years to cover these 87 billion km.

 

Size of the Universe 

If we multiply the speed of the expansion of the universe by the age of the universe, we get the radius of the universe:
13.8 billion light years x 3.38 times the speed of light = 46.6 billion LJ (light years).

The double radius would then be the calculated size of the universe: 93 billion light years.

Since the rate of expansion has changed and there is a possibility that this rate is not the same in every direction ("flat space"?), this number should be considered an approximation.
