Could earth's gravity be getting stronger?
« on: 26/07/2016 03:53:02 »
James J. Glanville asked the Naked Scientists:
   Hi my feet has bean having pain lately, walking is like the gravitation of the earth is getting stronger. With bombs, heavy
artillery, buildings collapsing and, atomic bombs once falling,
could there be a change to our human body getting bigger,
sitting in seats smaller due to change in the earth's gravity?
  Hi I'm James J. Glanville, I live in San Francisco, CA,
USA. I went to school for high school here in San Francisco
my British administrator of our school, Wildshaw School
was Mr. John Schlesinger Edwards MA University of
Cambridge UK. I wonder if any member of the administration
of The University of Cambridge might remember and have
any record's on this man, he was very hard and not too
good to us student's of his Privet School, Wildshaw School
now changed name to, Woodside International School here
in San Francisco, California, USA.
What do you think?

Unfortunately, that's too confused to be able to give an answer. I.e. you're not at all clear on what all that stuff about bombs and heavy artillery etc have to do with the pain in your feet. Also the term "lately" is very vague. I.e. "lately" could mean in the last few years in which case you might have gained some weight and that added weight would manifest itself by making if feel as if the Earth's gravitational field has increased since weight is the product of mass times the acceleration due to gravity. So while you might have been thinking that the Earth's gravitational field was getting stronger while your mass has remained the same, it could very well be that you actually gained some mass and since the Earth's gravitational field never changes so much that its noticeable you will feel an increase in your weight making you think that the Earth's gravitational field got stronger. But the answer to the question in the subject like is No. The Earth's gravitational field is not getting stronger. At least not to the point where its measurable.

I suppose Earth's gravity could be getting stronger if it's mass is increasing, for example by being hit by meteors or other objects. But I don't think anyone would get tired feet from the effect which would be too small to notice.
