The mathematics is clearly beyond your intellectual capacity so let's try the familiar balloon analogy.Wise up time. Hubbles Constant (Ho) is 71 k/s over a specified distance. It's a speed DISTANCE unit. Now the CLEVER bit that FOOLS you. If you want the reciprocal of Ho, you divide Ho into one, and the result is 13.8 billion LIGHT years (distance). My example of the reciprocal of 30 MPH is 2 minutes per MILE. It cannot be stated as 2 minutes only. The same with the reciprocal of Ho. It is 13.8 billion LIGHT years (distance), NOT years only (time). Is this beyond your understanding??
If you draw dots on a balloon and inflate it, each dot will move away from every other dot as the space between each dot which is a 2D surface is increasing. The dots themselves are stationary as they are not moving across the surface.
This is known as metric expansion which has the further property the velocity of a receding dot relative to any other dot increases with increasing distance between the dots.
This is clearly beyond your comprehension as when we refer to velocity and acceleration of an object when it travels from point A to point B, it is assumed A and B are fixed points in space and their distance remains constant.
In metric expansion however the distance changes and this needs to be taken into consideration.
This is why Ho has units of km/s/Mpc and not km/s as the recession velocity also depends on distance which is not constant.
