Not long ago you told me that time was a part of the universe.
You have told me that time is a dimension in the universe.
That means time could not exist until the universe began to exist.
Conclusion: Time being a part of the universe and inside of the universe the universe does not exist in time. Time exists inside of the universe.
Have you changed your mind about time being a part of the universe?
And you told me that time was a duration between events based on the position of the Earth to the Sun.
But your conclusion contradicts that.
Have you realized that your old concept of time is not the one that should be used for these considerations?
By the way, gravity is the result of the curvature of spacetime by mass.
