First, You have to understand that gravity has three dimensions.
- Gravity created by suns, planets and other celestial bodies with mass.
- Quantum gravity created by Quantum interactions.
- Event Horizon Gravity. Gravity that exists inside of a black hole that does not allow even the light of the collapsed star to escape.
Solar Gravity would not have existed prior to the Big Bang as suns would not have been present to create such gravity. Solar gravity is much like a lake on a windy day that creates waves for 2 to 3 feet in height.
Quantum gravity is thought to have exist prior to the Big Bang as a result of an unknown interaction between space and time. Quantum Gravity is much like a lake on a calm day without hardly any waves at all. More like smooth glass but with some slight valleys.
Black Hole comes from within the black hole itself and since no one has every ventured into a black hole no one can be for certain the extent of the actual gravitational influences. Black Hole Gravity is much like encounter waves on the ocean that are 1,000 feet high.
When a ship travels faster and faster it encounters Solar Gravitational waves first. A ship traveling at the speed of light would encounter millions of waves in a single moment even though the waves have 500,000 km in between the crest of each wave. The force exerted against the ship becomes to much for the engines to continue as there is not enough force propelling the ship forward to overcome all of the mass that it is encountering.
The ship drops back into normal propulsion mode and travels the wavelength down into the trough and then up the sides of each crest without any difficulty.
Solar Gravity is by far the largest amount of mass producing gravity in the Universe because Solar Gravity travels at the speed of light.
But if you were to reduce the amount of mass placed on the ship when it accelerates then you might be able to access Quantum Gravity for a much smoother ride. Reducing mass on a ship would be achieved by generating a field around the ship that strips the particles from atoms that create mass.
Basically you create a space that is void of atoms with mass that create the mass of space time itself.
Once in Quantum Gravity space your ship encounters gravity overall because the connection interactions between Solar Gravity and Quantum Gravity where energy is transferred from the Quanta to the atom is not a prevalent.
Your ship would be able to travel faster than the speed of light while not tearing you or your ship apart because the interactions between the Quanta, yourself and the materials of your ship would remain intact. The reason being is the mass reduction field itself is emitted away from the hull of the ship and is not directed towards the ship or you.
Think of a marble inside of a balloon that is being pulled through water. The marble could move around inside of the balloon at a faster rate occupying more space because there isn’t water placing a weight on the marble compared to the amount of weight placed on the marble if it was traveling through the water.
