somberness ’s often assumed to be constant across the entire planet , but because the Earth varies in conformation and density , that ’s not really the shell . Now , this crack - precise gravity mapreveals that the fluctuations are even more extreme than scientist antecedently opine .
A team of scientists from Curtin University in Perth , Western Australia , flap together data from artificial satellite accelerometer and topographical studies to map the alter gravitational champaign between of over 80 per cent of Earth ’s country flock . That involved aamassing over 3 billion point in time with a resolution of around 250 metres . crunch all the routine would take a normal PC 5 second per breaker point , but the team used a supercomputer to get it done in just three weeks .
While received physics model suggest that sobriety should vary between a lower limit of 9.7803 meter per secondly squared at the equator and 9.8322 m / s2 at the poles , theresults from this young study disagree . In fact , they found that Mount Nevado Huascarán in Peru has the lowest gravitative acceleration — at 9.7639 m / s2 — whereas the highest occur at the airfoil of the Arctic Ocean , at 9.8337 m / s2.New Scientist call for an amusing flavour at the moment of the finding :
[ I]n the improbable event that you institute yourself lessen from a top of 100 metres at each point , you would hit the surface in Peru about 16 millisecond later than in the Arctic . You would also lose 1 per centime of your soundbox weightiness in incite from the Arctic to the Peruvian mountaintop .
sentence to pack for Peru then , hombre . [ Geophysical Research LettersviaNew Scientist ]
