Damien Huxley asked the Naked Scientists:
Hi Chris,
I've been thinking about gravity maps and since we gravity mapped Earth and the Moon a thought has occurred to me that can we map other things...
Can we detect the Sun's gravity pull from Earth?
Can we detect Sagittarius A (Black Hole at centre of Our Galaxy) gravity from Earth or space?
Can we gravity map the Milky Way galaxy? If we could then we could see all the object out there including other black holes stars and dark matter.
As the Sun moves around in the spiral arms (Orion Arm) in the Milky Way Galaxy what are we rotating around in our local neighbourhood?
How do they map gravity?
Regards
Damien
