>>11198626dont listen to any of the above posters, they are clearly gov agents trying to give you fake info
as to your question
as we all know the universe is expanding, but not everyone knows that as it expands it streches out everything inside
so earth was streached quite a bit since dinosaur times
and since bigger objescts have stronger gravity pull the earth's gravity increased
I'm just not sure about the amount but it's anywhere from 1,3 to 2 times since dinosaur times
I hope that helps OP
