Summer Solstice is near and theories are flowing about the axis shift. The sun is too far north, the sun isn’t setting at the proper place, etc. I wrote a previous article about the Earth’s axis shift, just stating that it was completely nonsense to think that the axis of rotation changed but now, I would just like to provide a simple everyday life example of why it doesn’t make sense.
This example is called satellite T.V. I’m sure you know roughly how satellite T.V. works and that the antenna at your home as to be in direct line of sight with the satellite of your satellite T.V. provider. It does make sense, if you want your antenna to receive signal, it has to be in line with the satellite, otherwise it doesn’t receive any signal. Trust me, it’s not something roughly aligned: moving your antenna of a single degree can make a difference. Now, if you want to be able to communicate with the satellite day and night, it has to stay in the same position. How is this achieved? Well, that kind of satellite is called a geosynchronous satellite:
A geosynchronous orbit is simply an orbit that allows the satellite to remain apparently stationary above the same location on Earth.
In order for a satellite’s orbit to remain stationary above the same location on Earth, the satellite’s orbital period (the time required for one complete orbit) needs to equal the Earth’s rotational period – one day. Because the satellite orbits at the same rate the Earth rotates, the satellite remains stationary above the same longitude on Earth.
In addition for the satellite orbit to be truly geostationary, the orbit must not be inclined to the equator. Otherwise the satellite will oscillate in a north south direction above the same longitude.
Just like that:
So that’s why you are able to stay connected with the satellite at all time. Now, remember when I said moving your antenna of a single degree would make a difference, well now imagine if the Earth’s axis would shift! The Earth does move, but not the satellite. There aren’t any physical bindings between the Earth and the satellite which means your antenna is no longer pointing toward the satellite. So if you are still able to watch satellite T.V., the Earth’s axis is the same.
Also, it is ridiculous to think it wouldn’t have important impacts. Just the length of days would be different! I strongly encourage you to have a look at this video as it’s pretty good to understand the basics:
I hope it cleared it all!
