We all know that in this universe nothing can travel faster then the light. But, you know why why? Because the rest mass of the light particle known as photons is zero. Which means that that there is know weight of light.So, small force can produce large force .But, for other particle having only very little mass even a electron need energy more than presence in our universe to reach the speed of life.
There can life outside is discussed bu everybody. But, did you ever thought that there can be a life on the sun , on our sun. The reason we think that there can life on sun because the condition on the sun are not suitable for the life. But, its not true , life can exist at any point of the universe even on sun. Reason behind my this imagination the rule of science which says that DNA or we can things and living things make themselves comfortable toward the conditions when they live under those condition for long time. So, there can be a possibility that somehow any living landed on sun in past and died immediately but DNA survived it cannot be destroyed. Because it is form of information copied from parent to child and information cannot be destroyed, science says. And , after long time when this DNA become friendly to environment and reproduce it again in form of life . what you people think?
Today, in this world everyone is in hurry and worry ,some are running for the money they want more and more ,because of making their life high standards . And, in this passion they lost their whole life , after doing everything when the end is near then people think that everything was just Waste.
MY ASSUMPTION $ = the apostasy ,religion , truth , lie , honesty ,betray , love , hate everything like is just creation our mind or our elder’s mind creation. Lets go millions year ago when there was nothing on this earth , is there was any any ethical and moral values ? At, that time there was nothing was true ad nothing was false. Then, after long period the life start existing on earth. And , i clear one thing here i consider our elders to the single cellular living thing, means first living thing on earth. After, the birth of this first living being the life standards on earth start developing. And, as the mental abilities of living beings increased they start considering the things that this one is true and this one is false.
At the end, today way of our thinking is just a impression of our elder’s thinking .We are just following the path showed by our elders .These ethical values are just illusions created by elder just to make life smooth. For instance, in the past if they had considered that speaking lie is good thing then we was going to follow this path. The universe is very big it neither love anyone nor hate. Our existence cannot make any effect to it and if we also not going to change its speed. The universe is million time bigger than our thinking even existence our earth does not going to effect anything so, what we are. According to me, religion, truth , lie all are made by us , these all thins are illusion. There is only one god of the universe that is nature we should worship the nature rather than bow down in front of any monument or grave. Feel free, live free do what you thing true, do’nt run behind the fame , money etc these all illusions try to absorb into the nature .A day when you successful in this you will be able to get out through this boring circles created by world. Try to get close to the nature , try to understand it and explore it.
Q1 what is a life Span ? Life span defines the existence of anything that how long an object or living thing take to reach its end point and after reaching the its end point , it will disappear from the universe.
Q2 what is life span of star ? It is the time star existed in the universe. After this time the star got disappeared from the universe. Q3 What is the age of the star ? MY ASSUMPTION $= According to my science age of the star depends upon the speed of time on it. If the speed of time on any star is fast then the the age of star will be lesser than the comparison of star where the speed of time is slow. The speed of time at any point depends upon the Gravity of that point.The point having low gravity have time speed fast but, where the gravity is high the time speed becomes slow. So, the points having high gravitational field have large life span. Q BUT, ON WHAT THE GRAVITATIONAL FIELD DEPENDS ? The gravitational is directly depends upon the mass of object.Means the point having high gravitational field have the high field of gravitational. And, the lower in mass of any object will reduce its gravity. FOR INSTANCE , its a fact that the life span of our earth is lesser than the sun , and the surviving period of moon is lesser then earth . And, if you check the mass pf the sun is million time more than the earth , same phenomenon in case of earth and moon. SO, i can say that the life span of any object depends upon its mass.
This is picture of dying star.
