What is expansion of Universe and Scienctist measured that the how much speed of expansion of universe 2021 Science hub
Hello friends,Welcome to you in Science hub. I hope you are happy And I'm also fine.
Friends today's we are going to discourse about the the expansion of the universe and how much speed is it expansion .Did Scienctist calculated the expansion of the universe means it is right or wrong. Do read the this post to know it's reality.
Friends firstly I request you to please subscribe to this website if you are interested in post.

Let's we start
As the Universe expands ,the galaxies move Away from the earth. The speed with which they move from the earth depends on the distance which is between the earth and the galaxy .
Scientist says that the universe expands continuously no one has understood that the how much speed this is expansion.

Atleast the all Scienctist has not sure to other . That's why it is the mystery of the world's Scienctist. But the right now the Scienctist has got some information . From which we may possible we can answer of this Question which is the mystery for the world.

When the black hole and neutron star are collides in the universe then their gravitional waves we can measure. Means we can observe that gravitional waves which is coming by the hitting of black hole and neutron star.
Normal telescope can not observe this gravitation waves . But the detector can the detect this gravitational radiation.
What is Hubble constant in 2021 ?
Now we are going to discourse about Hubble constant. Scientist shown hope that based on this information .we can understand this fact. Scientist think that it may be prove helpful based on this observation. Actually as the universe expands , then the galaxy move away from the earth.
It is going to away from the earth it's depends on the distance which is between both of them. And which is relation between both of them we called the Hubble constant of this relation.
Firstly This is calculated by the Advin Hubble in 1920 . He is the Astronomer of America.

Therefore ,we says of this relation Hubble constant based on their name. Many researchers are measured the Hubble constant with Accurately. But the problem is that , in different way the second value has come out different from that value , based on the cosmic microwave background .
It was generates after the 3.8 Lac of big-bang . Due to this problem , the Scienctist are not Sure to each other. Due to this problem it is mystery. For the Scienctist.

How generates the gravitional waves .
When the Major black hole and the neutron star are collides then while the colliding this gravitional waves generates from the black hole and neutron star.
This is told the state university of Pennsylvania's Scienctist .
In 2015 , LEGO ( Leser interferometer gravitional waves Obeserbatry) of America and their Utopian partners VIRGO both are tried to detect like that signals .
In last words
Friends in this post we learnt or we know about expansion of universe. And Letest updated based on the this topic.
Even in short we have known about the gravitional waves like how is released from the black hole and neutron star. Means how is it generates.
Know about this
