why do people persist in the idea that gravity is zero at the centre of the earth cos you would be surrounded by earth?
EARTH creates a distortion in space that creates the effect of gravity - THAT distortion is at its maximum (NOT its minimum) corresponding to the centre of the earth, and THAT dont change no matter WHERE you are inside the earth
16 個解答Astronomy & Space2 年前Why do so many people on YA believe dark energy/matter to be establed scientific fact?
when they are BOTH hypotheses that explain phenomena in the universe that we cannot explain by our current understanding (and there ARE other hypotheses that explain them)
(for those who dont understand what a hypothesis is I suggest getting a dictionary - its no better than an educated guess)
Both of these have been assumed to have properties in order to explain the phenomena, but so far there is NO actual evidence that either exists.
And just cos in so many scientists "opinion" they exist does not make them fact
The ONLY facts we have are that the phenomena exist.
The only explanations we have are hypotheses (educated guesses) NOT facts.
Maybe in time they will become fact but at THIS time they aint
