Why does time slow down when youre experiencing gravity and speed up when there is no gravity,

and how does it relate to time slowing down when youre travelling faster,

and how much has time slowed down for us because of the speed of our world and solar system and galaxy rotating and traveling in space

is our galaxy travelling in space as well or is space only expanding

I read some where that in formation of egg some specail materials are required which are only found in hen in simple words only hen can produce egg so i think hen came first
If evolution is to be believed, then the hen came first. If you're a creationist, even then, the hen came first :p

Clocks which are far from massive bodies (or at higher gravitational potentials) run faster, and clocks close to massive bodies (or at lower gravitational potentials) run slower. This is because gravitational time dilation is manifested in accelerated frames of reference or, by virtue of the equivalence principle, in the gravitational field of massive objects.
And now because more and more clocks are made so thats how clocks are getting a little bit slow. And since the gravity of earth has increased as compared to the past so the gravity also slows the clocks.
The universe is expanding in the speed of light.

What came first? Hen or egg?

Basically, many, many moons ago there was a chicken-like bird. It was genetically close to a chicken, but wasn’t a full-blown chicken yet. Krulwich calls it a proto-chicken. So proto-hen laid an egg, and proto-rooster fertilized it. But when the genes from ma and pa almost-chicken fused, they combined in a new way, creating a mutation that accidently made the baby different from its parents. Although it would take millennia for the difference to be noticed, that egg was different enough to become the official progenitor of a new species, now known as … the chicken! So in a nutshell (or an eggshell, if you like), two birds that weren’t really chickens created a chicken egg, and hence, we have an answer: The egg came first, and then it hatched a chicken.

What is in between science?
Your question is not correct.

how does the theory of relativity apply to the space time continuem?
In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity. It introduced a new framework for all of physics and proposed new concepts of space and time.
Einstein then spent ten years trying to include acceleration in the theory and published his theory of general relativity in 1915. In it, he determined that massive objects cause a distortion in space-time, which is felt as gravity.

Theoretically, it is. As explained by Stephen Hawking in his book "a brief history of time"
Man that is common sense, nothing happens by writing a book.
Tell stephen hawking to do it practically.
Once time is gone, it cannot be back again.

star shape me kese hote hain ?

is there anything hotter than sun ?

sab se bara flare kis jaga se nikalta hai or es ka kia concept hai? or ye destruction ka baais kese ban sakta hai?

well i had to ask u these questions in urdu so that u can get it easily what exactly i want to ask if u answered these questions correctly i will ask u more

Hit me with a PM when you're scientifically aware enough to answer questions on your own instead of resorting to copy/paste and I will open this thread.
