The universal accelerator interacts with celestial bodies, like the sun.
You are not explaining either
how or
why that happens, just that it does. It is easy to say something happens, but so far it doesn't seem to be easy for you to explain the mechanism behind it. More information please.
All you have said at the moment is that something which itself is just hypothetical somehow interacts with the Sun. That is not really a good explanation is it.
Let me explain what I mean. We all see the Suns declination vary during the year from +23.5N (21st June) through to -23.5S (21st December). So that is what causes the seasons. We can explain why this annual movement of the Sun happens by the fact that the Earths polar axis tilt (of 23.5 degrees) means that for half the year the Earths northern hemisphere is tilted towards the Sun while for the other six months the Earths southern hemisphere is tilted toward the Sun. In short we have explained the cause of what we see and experience every year.
However if you prefer to believe that the Earth is flat and that the Sun moves in circles over a flat Earth then clearly none of the above is possible. So the only way you can account for the seasons is by saying that the radius of the Suns orbit above the Earth increases and decreases over the Year. The problem with that is you have to explain both why the Sun moves in circles in the first place and secondly why the radius of that circle just happens to vary in synchro with the time it takes to complete one orbit.
All we've had from you so far is some vague comment about an 'interaction' between something which has never been shown to exist and the Sun. Over to you again...
