rickymouse, Oh man!!! I remember the strawberry shortcakes my mother made when I was growing up! Awesome... just awesome! No one can beat my mom's cooking or baking, not even me.
Now you have my mouth watering for strawberry shortcake with the berries from the garden. They have so much more flavor than store-bought.
Alas, my heart breaks because I have no garden strawberries.
This isn't anything new. I watched my first video on this when I first joined TOS back in early 2011 and it wasn't exactly new then either. The pole has indeed shifted by many miles and continues to shift every day. Some of it has shifted due to natural changes and some due to major earthquakes- example being the really big earthquakes in Chile and Haiti that each shifted the pole by a few degrees.
It's new to me. It was only this year that I noticed the sun was in a different area when it sets, compared to last year. And Nugget has noticed some recent changes too. Yes, I think the earth has shifted more recently due to the quakes. Wonder what's next?
I would think if anyone knows an employee in the right place, if the tilt of the earth changed, terrestrial satellite antenna's would have to be realigned to point in the right direction to achieve the best signal reception. They might still receive but remember if the antenna is off say a couple of inches on the planet then that would mean they could be off a mile. Does anyone know any of the numbers involved?
@marlingrace,My husband deals with communication equipment fo a living, so I asked him about this....he explained it to me to where it made sense, so I hope I don't mess it up too much in the re-telling.
Sattelites are 23,000 miles out, and they follow the earths rotation, so a change in the 'wobble' would need to be VERY major for it to have a noticale effect. The sattelites are beaming a pretty broad signal, which would also require a major deviation to make a noticable change, plus the majority of them now days have systems to keep them in alignment. He said something about GPS tracking too, but my brain was starting to go on overload at that point.
Mystic, are you going to touch on the expanding earth theory too??

The biggest reason the strawberries taste better is because they are picked totally ripe. When we had a farm we had to pick them with white tips so they wouldn't go bad when shipped across the country. The ones we sold locally were fully ripe. The good tasting chemistry doesn't form if they aren't picked ripe. The berry will turn red but not develop it's flavor. I grew up in the strawberry fields.
The berries we get were picked in the morning and delivered here around two, picked ripe with nothing added to preserve them being needed. They get sweeter as the water in them evaporates a little and even more chemicals are converted, because they were picked ripe. These berries are Jewells, not as sweet as sparkels but they are still really good berries. Sparkels are smaller berries and perfect for the home garden where you just pick some off plants as you walk by. People like big berries though. I prefer the smaller ones because they are sweeter and have more taste. But these berries are full of flavor. When you add a little sugar they are like having a flavor burst in your mouth.
Growing up on a farm I know about what we used to grow. I can grow strawberries and potatoes pretty good. Trouble is we have deer that like to eat the strawberry plants here, so I don't get enough berries to do anything with except snack on. There has been a little fawn walking in the garden lately, tiny prints. It ate the tops off a few radishes a few days ago. I'm going to plant some wheat next spring or I may try planting some next week to see how it goes. I have about twenty pounds of whole wheat and we tried some and they sprouted.

Thanks nugget, I understand it completely I had no idea they were self aligning. I should have thought about that even personal telescopes come with GPS to locate itself on the face of the earth. It only makes sense to have the antennas self align. Tell him thanks, he sounds like a smart guy. You should get him on HH so we can give him hell to...LOL
Outstanding Mystic! Since the first time I looked at a globe as a kid, my mind could see how all the pieces of land would fit together like a jigsaw puzzle, but it wasn't until recent years that I heard about the expanding earth theory.
Would that not also explain how artifacts are being found on continents where the people couldn't have possibly traveled with their limited sea-fairing abilities? It might also explain why governments go out of their way to hide any archaeological discoveries that don't fit the story we've always been told.

Long ago, I spent a time installing satellite dishes (the great big 7-10 foot "West Virginia State Flower" kind). If you're off by half a degree, it will miss the satellite altogether, and you get nothing, or, at best, a very weak, very noisy signal. The satellites for TV are in geostationary orbits above the equator - they stay above the same geographic point, all the time. GPS satellites are different. They orbit at a different distance (about 24,000 miles) and have predictable orbits that put the satellites at different points constantly, which is why a GPS has to download an emphemeris every so often from the satellites in order to be able to predict their positions.
A geostationary orbit is at 22,236 miles above the surface. I'm not sure I recall all the formulae correctly, but I think to determine offset at distance, it's tan(theta)*d, where "d" is the distance involved and "theta" is the angle you are off by, which would make a half degree off come out to 194 miles off at that distance - a half degree in pointing points at an area 194 miles from the actual location of the satellite.
To make matters worse, back in those days there was an entire string of satellites along the equator, and we had to have special mount armatures made (based on latitude) to track the dish along a specific arc to hit them all, then manually move it and mark the point for each one so the equipment knew when to roll to and stop to hit it when the robots took over the pointing. The actual antenna was just a half-inch long bit of metal in what was called an "LNA" (Low Noise Amplifier) at the focal point - in the "bucket" at the end of the central arm. The dish itself was just a parabolic reflection surface to gather signal from a larger area and bounce it back to focus on that itty bitty nib of antenna. Because of the parabola on the surface of the dish, it had to be aligned just so, or else the focal point was not where the signal got focused to.
LNA's have been replaced now, and they use an LNB. I have no idea what "LNB" stands for.
The newer, smaller dishes use the same principle, but each only lives off of one satellite, so tracking to different satellites is taken out of the satellite TV equation these days. The surface is a section of a parabola rather than the entire parabola, which is why the focal point appears to be offset - it's not. the actual reflection surface of the dish is what is offset. The same principles apply to pointing, however - they have to be damn near dead on. I installed my own in NC rather than having a tech come all the way out into the boonies to do it, and found that a quarter degree wobble in either direction from dead on degraded the signal considerably. That's why it's so important to lock them down hard once you get the strongest signal possible, so that wind or a bump won't cut them out altogether.
The satellites themselves ARE adjusted occasionally, to account for drift. I doubt they'd be able to adjust enough to account for a sudden axis shift.
The Earth's rotation does "wobble" over time, with several different wobbles all on different schedules, but most of them are irrelevant and minor enough not to need taking into account. The biggest is the "precession of the equinoxes", which is a wobble on the order of 25.000 years or so that successively rotates the ascending node of the ecliptic plane through all of the zodiacal constellations back to it's origin over that period of time. For example, "the first point of Ares" actually WAS in Ares when it was named, but it's not any more - I think it's in Pisces now, but I'm not sure of that - only that it's not in Ares any more. The same motion causes the celestial north pole to describe a circle in the sky - Polaris was not always the "north star", and won't always be... but the pole will eventually come back to it.
The sun does appear to rise and set at different points in the sky (look up "annalema") as the year progresses, moving north and south on the horizon. It is farthest south on December 21, and farthest north on June 21.
Also, the angle or "tilt" of the Earth's axis changes over time - it hasn't always been at the same angle it is now, nor will it always be there.
AND the rotation is slowing down - 300 million years ago, a "day" was 22 hrs, 15 min (+/- 5 minutes or so) long. Now it's up to 23hrs, 56 min, because the rotation is slowing.

I don't believe in the Expanding Earth, but I'll give you some ammunition for your theory for free, because I'm in a generous mood today: What about the aborigines getting to Australia 45,000 - 60,000 years ago without ships? Or Homo Erectus getting to Java nearly a million years ago without them?
Your husband is right that they send a "broad" signal out - they have to cover the entire US from a point the size of a school bus or smaller 22,236 miles away. Because of the inverse square law, that signal gets weaker as it goes along getting wider. that law is 1/(d^2), but what that really means is that when you spread the same amount of something out more, it is thinner per square foot.
By the time the signal gets here, it's pretty weak, which is why you need a parabolic reflective surface behind the antenna to gather as much of it as possible and then "bounce" all of that signal from all of that area to concentrate it at a point 1/2 inch long - it's like the spot on a flashlight, which also reflects from a parabolic surface.
The parabolic shape is what causes each wave of the signal to reflect to the same point. Because of that, if the dish is pointed even slightly away from the satellite they are coming FROM, it alters where the waves are reflected TO, focusing them somewhere other than where the antenna is to receive them. In the flashlight analogy, it puts the "spot" in the wrong place, just like turning your wrist holding it does.
The same thing happens if, on the other end, the satellite drifts away from where it's supposed to be relative to the receiver dish. In both cases, the alignment is messed up, and your TV signal goes zoinkers.
