It is said that who does certain Yagas like the Aswamedha Yagas successfully becomes an Indra, dethroning the present incumbent.
Severe penance also warrants these results.
So Indra disturbs those who engage in these activities.
Now coming to Astronomy.
Time takes a toll on everything in the Universe.
If affects people and non living things.
People age so also the Rocks etc.
There are two aspects of Time, one is so minute that you do not notice it and the changes effected by it, like Micro seconds, nano seconds and seconds,minutes.
Even changes that occur hourly can be known only with the help of special instruments.
The other aspect of Time is it is so huge to be comprehended, like a light year or AU, Astronomical Unit that is equal to the distance traveled by Light in a Year.
One can not see this as this is a huge number and one may not be alive to see the change by oneself.
Such huge numbers are involved in the Universe in respect of formation of Stars,Galaxies .
Now all of us know the Earth has two movements, one spinning on its own Axis and another moving around the Sun.
The movement around the Sun’s signs by the earth is so slow that it is not noticeable.
Also because of the movement of the Earth and the Stars and other Celestial objects these objects change their relative places.
To put it simply, Stars change positions as also the Earth, taking the Sun as a reference point.
That the Sun also moves and there are many Suns is a different issue and I shall be posting on the implications.
