The biggest problem with cosmic expansion is that space is a quantum entity.
Space itself cannot expand,if you have a unit of minimum size how can you expand it?
When the universe came into existence space was at it's maximum density,as matter formed it's density decreased.
This was the only expansion of space,the quantum units did not grow.
The apparent accelerating expansion,and the red shift is the result of a misinterpretation.
Galaxies are an end stage in the evolution of a universe and the red shift [which would be seen from any direction] is the result of a vanishing galaxy.
The galaxies seen by the Hubble at extreme distances don't exist any more.
How could they be in a state of recession?

Maybe you already are dizzy.
But that could be from other reasons. What modern cosmology models say is that the space is being expanded between objects.
Between us and that galaxy, way out there, the amount of 'void' space is getting bigger all the time, making it look like one galaxy is moving away from the other at great speed.
Yet each galaxy is almost at rest in relation to its own neighbourhood.
If you are on Earth's equator, you are spinning around once every 24 hours (speed of 1670 km/h = 1040 mph relative to Earth's centre).
Earth's centre is wobbling once per month around the 'barycentre' (centre of mass of Earth + Moon) located 4670 km from Earth's centre: a speed of 45 km/h (28 mph) -- OK, that may be insufficient to explain the dizzyness.
Earth is orbiting the Sun at 29.786 km/s (107,230 km/h = 67,020 mph), relative to the Sun (actually, relative to the Sun-Earth barycentre, but that is a minor difference).
At midnight, at New Moon, on the equator, you'd be zipping along at 1670 + 45 + 107,230 = 108,945 km/h.
Relative to the stars in our neighbourhood, the Sun is moving at 19.4 km/s (69,840 km/h = 43,850 mph) towards the constellation Hercules.
The neighbourhood of the Sun is moving around the Galaxy at 230 km/s. Our Galaxy (relative to the Local Group of Galaxies) is moving around the Group's centre of gravity, and we are getting closer to the Andromeda Galaxy (the galaxies could merge in about 5 billion years, about the same time as our Sun goes into its red giant phase: now that will make some people dizzy).
The Local Group is being attracted by the 'Great Attractor' (centre of mass of a supercluster of galactic clusters, it is about 200 million light-years in the direction of Centaurus). Let us say, for now, that we are moving at 700 km/s relative to the Norma Cluster. That is still less than 1/400 the speed of light.
On our way there there -- may take a while -- our Local Group may merge with the Virgo cluster.
By that time, of course, The Milky Way and the Andromeda Galaxy will have merged into a giant elliptical galaxy, our Sun will have become a dwarf and the dizzyness will just get worst.

First off, motion has nothing whatsoever to do with dizziness. Dizziness would be caused by sudden acceleration, especially rotational acceleration.
Secondly, the Hubble expansion isn't even MOTION. It's the expansion of space ITSELF and the matter simply gets carried along. So there is nothing to feel.

Because the Creator of the universe set out receptive capabilities in a way that filters everything harmful. Think about the Earth's speed per hour. We do not feel if the Earth is revolving, yet, it does indeed.
