Gravity has to have an effect on time,when gravity can curve space ,it

In summary, space and time are affected by gravity. Gravity also has an effect on time which has remained unaffected or has been continously going forward all these years.

gravity has to have an effect on time,when gravity can curve space ,it also
has to influence time,time that has remained unaffected ,or has been continously going forward all these years,from the time humans existed .

gravity has to retard time,even though time could be a 4 dimensional aspect.

I don't see a question anywhere there, but yes, there is gravitational time dilation. Note, though, it is only calculated with respect to something else (say, a spaceship in orbit around earth) and for the mass of the Earth it isn't very much.

why is not very much for mass of earth?

Earth's mass just isn't enough to cause a big distortion. Consider that sun has more than 300,000 times the mass of the Earth and is a small to medium-sized star.

Something that could cause a time dilation would have to be an object like a black hole that exerts a very strong gravitational field

will we consider time a scalar or vector quantity,since time does have a direction
it moves forward ,it has to be a vector . time has been looked as a scalar qty in many places.

why is it not possible to determine the volume of the universe using integral calculus
taking limits as infinity,roughly what we see around us ?

We don't exactly know the specifics of how time works with cercumstances other than what occur naturaly so its possible that it could be one or the other or both.

a black hole has to be a perfect black body,as a perfect black
body emits or absorbs all radiations,a black hole does.
 

What is the relationship between gravity and time?

The theory of general relativity states that gravity is not just a force between two objects, but also a curvature of space and time. This means that the presence of massive objects can cause space and time to be distorted, ultimately affecting the passage of time.

How does gravity affect the curvature of space?

Gravity is caused by the presence of mass or energy, and this mass or energy can curve the fabric of space. The more massive an object is, the stronger its gravitational pull and the more it can curve space.

Can time be affected by gravity without the presence of mass?

No, time cannot be affected by gravity without the presence of mass or energy. In order for gravity to have an effect on time, there must be a massive object present that can curve space.

What is time dilation and how is it related to gravity?

Time dilation is the phenomenon where time moves slower for an object in a strong gravitational field compared to an object in a weaker gravitational field. This is because the stronger the gravitational pull, the more space and time are distorted, leading to a slower passage of time.

Is the effect of gravity on time significant in everyday life?

The effect of gravity on time is very small in everyday life. It is only noticeable in extreme situations, such as near black holes or in space where the gravitational pull is much stronger than on Earth. For most daily activities, the effect of gravity on time is negligible.
