That's a really hot question among cosmologists and astronomers.
No positive evidence of a change through time has been found, but then,
how would you look for it or measure it out in the universe ? ! ?
The gravitational constant, denoted as G, is considered to be a constant value in physics. It is a fundamental constant that is believed to remain the same over time and across the universe.
Death, change, and time are considered to be three constant things in this world. Everything eventually comes to an end, change is inevitable, and time continues to pass regardless of our actions or desires.

constant acceleration is when you gain the same speed over the same time
Some constants of the Universe include the speed of light, gravitational constant, Planck's constant, and the fine structure constant. These constants govern the fundamental forces and properties of the Universe and are crucial in understanding how the Universe functions.
It is in constant change.
Time is change, and the opposite would be a constant.
In theory ... on paper where you have ideal components ... a capacitor all by itself doesn't have a time constant. It charges instantly. It only charges exponentially according to a time constant when it's in series with a resistor, and the time constant is (RC). Keeping the same capacitor, you change the time constant by changing the value of the resistor.
The gravitational time dilation equation is given by t' t (1 - 2GM/(rc2)), where t' is the time interval in a stronger gravitational field, t is the time interval in a weaker gravitational field, G is the gravitational constant, M is the mass causing the gravitational field, r is the distance from the center of the mass, and c is the speed of light. This equation shows that time slows down in stronger gravitational fields because the gravitational force warps spacetime, causing time to pass more slowly closer to massive objects. This effect is known as gravitational time dilation.
Depending on the situation, a rate of change can be constant (at least over a certain time period), or it may be non-constant.
An input that does not change over time.
No the ozone hole is not constant over the time
