Some time ago I wrote about climate change and space junk.
Here is another one for you to ponder.
Gravity changes on a daily basis and is not constant as some scientists would have you think and believe.
Gravity does change and the proof is in the oceans and the tides. If gravity was constant then there would be no tides. Then there is the super tides when the planets align.
Some will say that the earths gravity has to be the same and this would be the case if it were only the earth but this isn't, so there is planets and the moon reacting with the earth all the time. It can not be any other way.
One thing we can be certain of is there will be change. This goes for all things including light and its speed!!
