If the light doesn't has no mass then why it Attracts to the block hole | Science hub , Letest post 2021
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 light and it's mass , effects on the Gravity. Means if the light or foton has not mass, then why do they attracts towards the black hole's.
Must read:
• how to become an ISRO scientist
• educational life of Einsteins
• how many types of black hole 2021
Means why they feel gravitional force. Because According the Newton's law of gravity , Gravity works between two things both thing must have has mass. It means that Gravity depends on the mass. But the foto which is the particle of the light and it has no mass.

For understanding this fact you will have to understand the spacetime . Newton's has given this theory . Before einstein , Newton said the time is absolute . It means time is not relative with other. But the it is not relative . Time is relative. It means that in the space time is not same .
But In the different places , times' value is different. I mean that if two person both are brother . One of them , has a government job . And second one is the astronaut.
When the space mission want to send the second one man in the space for the research in the space. Then the second brother met the first brother.
And after meeting with first brother he went for the space mission. He doing research in the space . After 2 years astronaut comes on the earth . And meet him first brother. And see the first brother that second's one brother get old.
Means for the second brother , many years passed . But in the space time is slow . That's why for the first one, passed two years in space during space mission .
Hence in the space time is not equal anywhere. This is relative . Means the passing speed of time , depends on the gravitional force and the velocity of the an object.

If my Gravity and the velocity is different to other , then the our passing time , also will different . because the time is depends on the gravitional force and and the velocity of objects. Means where there is more gravitional force , there time slow down.
•what is asteroid, comets and mateorite
• why is so expensive Antimatter?
Let's we understand it, by one example, if one man lives on the Jupiter planets then there man will be alive more days than the Earth's alive man . Because the Jupiter planets is more big than the earth. Then there is Gravity is too much. And will time slow down of there. Or if we are traveling as space craft which speed is equal the light's speed.

As well as you will have to understand the general theory of relativity , According to the general theory of relativity says that everything which is in space creates curves or torsion According it's value and size .
Now you are thinking that what is relation general theory of relativity. But I'm about to tell you. How is it relative .
In space creates curves because of object's sizes and value. Because of this curves .this is reason of the light falls in the black hole . While light has no mass . When the light pass nearby the black hole , the light is falls into the black hole due to his curve .
Further a foton always travels between shortest distance between two points . As space time warped the appears to bend around a massive object . But in reality is is not that the object is attracting the light , but is is just that the photons are traveling by shortest distance In a curved Space time .
Around the black hole, the distribution of the space time is extreme .At the event horizon of black hole the space time curved into itself and as the result light can't escape from the black hole.
In Last Words :-
Friends in this post we have known about if the light doesn't have mass then why is it fall in the black hole . I hope this post will prove helpful for you.
