If you were to replace the Sun with a white dwarf, neutron star, or black hole of the same exact mass, the gravitational force acting on Earth would be no different. While it's true that the fabric of space is curved by the presence of mass, and that black holes offer the greatest concentration of mass anywhere in the Universe, it's also true that the density of that mass doesn't matter for how space is curved. Every single particle that makes up an object affected by a black hole is still subject to the same laws of physics, including the gravitational curvature of spacetime generated by General Relativity. Still, the idea that you'll get sucked into a black hole remains a misconception, and a doozy of one at that. For an LHC-mass black hole, these forces are inconsequential, as they're negligibly small, but for black holes like the type at our galaxy's center, tidal forces close to the event horizon can be enormous. This artist’s impression depicts a Sun-like star being torn apart by tidal disruption as it nears a. These force lines map out the relative forces an object experiences, and explain why objects that experience tides get stretched along the direction of the force and compressed perpendicular to the direction of the force. Like all physical objects, the Earth is three-dimensional, which means the "top" and "bottom" areas of the Earth (from the Moon's point of view) will get pulled inwards, towards the center of the Earth, relative to the portions located in the middle.Īll told, if we subtract out the average force experienced by every point on the Earth, we can see how all the various points on the surface experience the external forces from the Moon differently. Department of Oceanography, Naval Postgraduate Schoolīut there's more than just the fact that parts of the Earth are closer and parts are farther away from the Moon.

Different points along that object will experience slightly different forces, resulting in a net tidal force: the differences between the force on the individual points versus the average net force on the entire object. From anywhere on the surface of a physical object, there will be a force pulling it in the direction.
