🛰For the most part, the history of volcanic activity on the terrestrial planets conforms to the predictions of this simple theory.
🛰The Moon, the smallest of these objects, is a geologically dead world. Although we know less about Mercury, it seems likely that this planet, too, ceased most volcanic activity about the same time the Moon did.
🛰Mars represents an intermediate case. It has been much more active than the Moon, but less so than Earth.
🛰Earth and Venus, the largest terrestrial planets, still have molten interiors even today, some 4.5 billion years after their birth.

#Timetravel
👉An event with no beginning and ending is called a #loop. Even though it seems possible to travel back in time back to past .There are temporal paradoxes that would seem not possible to travel back in time .Let's make a quick review through the common temporal paradoxes.
Grandfather paradox:
👉Suppose, you made a sincere request for a sports bike to your family. Everyone agreed except your grandfather. Then you became extremely angry and you got the instinct to kill him. And you used your genius mind and created a time machine and travelled to the past at
that time when your grandpa was young, and you killed him.
👉It seems you will feel satisfied and happy because you killed your future
villain. But the main twist is that how you killed him?🤔 Because you killed
your grandfather even before your father was born. So it means you are not born. 🙄Which further implies you didn’t create a Time machine,which means you didn’t kill grandfather. And in the end, it means you don’t even exist and grandfather is still alive.As your grandfather is alive, he got married, and then your father was
born, and then you came into existent. Now you desired to have a
sports bike......
👉it sounds funny, but you have created an infinity loop which won’t end. While this loop is a time paradox, and this time paradox is termed as Grandfather Paradox.
Bootstrap paradox:
👉Now imagine, you heard a knock on your door. There was a parcel lying on the floor. You opened it and found a procedure and formula to build a time machine. After your perseverance, you created a time machine.Then to test it you travelled into the past and gifted the procedure and formula to your younger self. Then that younger self again created the time machine and gifted it to its younger self.So this creates an infinite loop. So basically who kept that parcel at the beginning? This time paradox is known as a Bootstrap paradox.
Predestination paradox:
👉Now Imagine, you are the man and created a time machine and travelled into the past. There you met a lady (who is going to be your mother in future) and fell in love with her. Years later, you both got married and had a baby. This baby is going to be the man who actually travelled back in time in the first place.
👉In simple words, you and your mother got married and had a son, and ultimately you found that the son is you! (It’s like, A marries B, and have so A). This paradox is known as predestination paradox.And finally,
Twin paradox:
👉Suppose imagine, ‘A’ and ‘B’ are twin brothers and say ‘B’ leaves the planet Earth and travels in space at high speed. And after 10 years B returns to Earth. Will ‘A’ and ‘B’ be of the same age? So the answer is no?

#Differentiation
👉is the process by which gravity helps separate a planet’s interior into layers of different compositions and densities.
👉 The heavier metals sink to form a core, while the lightest minerals float to the surface to form a crust. Later, when the planet cools, this layered structure is preserved.
👉In order for a rocky planet to differentiate, it must be heated to the melting point of rocks, which is typically more than 1300 K.

👌Emotions are also essential if you view the evolution of the human brain. If you look at the gross anatomical features of the brain, you notice that they can be grouped into three large categories.
👌First, you have the reptilian brain, found near the base of the skull, which makes up most of the brain of reptiles.
Primitive life functions, such as balance, aggression, territoriality, searching for food, etc., are controlled by this part of
the brain. (Sometimes, when staring at a snake that is staring back at you, you get a creepy sensation. You wonder,What is the snake thinking about? If this theory is correct, then the snake is not thinking much at all, except whether or
not you are lunch.) When we look at higher organisms, we see that the brain has expanded toward the front of the skull.
👌At the next level, we find the monkey brain, or the limbic system, located in the center of our brain. It includes components like the amygdala, which is involved in processing emotions. Animals that live in groups have an especially well-developed limbic system. Social animals that hunt in groups require a high degree of brainpower devoted to understanding the rules of the pack.
Since success in the wilderness depends on cooperating with others, but because these animals cannot talk, it means that these animals must communicate their emotional state via body language, grunts, whines, and
gestures.
👌Finally, we have the front and outer layer of the brain, the cerebral cortex, the layer that defines humanity and governs rational thought. While other animals are dominated by instinct and genetics, humans use the cerebral cortex to reason things out.

#Supernovae
👌supernova is an extraordinary explosion of a giant star at the end of its life,accompanied by a sudden increase in brightness and the release of a great amount of energy. In 10 seconds, a supernova releases 100 times more energy than the Sun will release in its entire life.
👌 After the explosion of the star that gives rise to a supernova, the gaseous remnant expands and shines for millions of years. It is estimated that, in our Milky Way galaxy, two supernovae occur per century.

✨Theories of Shape of universe
1.flat universe - theory according to this theory the universe continues to expand but at decreasing rate as compared to its Early formation . even though expansion undergone at declining rate it's continuity will be ever lasting
2.Open universe theory -according to this theory the universe continued to expand from the critical mass of infinite dense continue to expand and the only way that it could die is when objects reach absolute temperature and the entropy stops.
3.Closed universe theory -As perspective of this theory the universe continued it's expansion from critical mass and later its end could be by reversing the expansion by big crunch ... which means later go back to where it was ...or degrade to critical mass .
4.Self generating universe theory -and as this thesis it's that universe infinity continue to be created like branch of tree and each linked to the other by the black holes ... that's why some scientists say through Black hole we can travel to another universe .
5.Baby universe theory -which is also most accept theory of these ,says universe continues to replace each other.Meanwhile one reaches its death either big crunch or else the other baby universe will replace it in the form of expansion from critical mass .
