We need anti-gravity for spacetravel

[geniuslvlintel74]

If we are going to travel to other points in space then we need to master anti-gravity. Every large "body" in space has some degree of gravity to it so if we can develop anti-gravity it would simple to get from point to point. Every solar system has a sun and these suns have the most gravitational force in their respected solar system, think about it they hold the planets in a orbit. If you use anti-gravity you can skip to the nearest planet by repelling from whatever gravitational force you are near to the next GF (gravitational force) closest to you. Or if you wanted to go interstellar dial into the nearest sun. Im not a documented genius but damn that just seemed obvious! tell me your thoughts!

"Any alien UFO accelerating faster than 8 g is drone. Gravity is not space curvature but an energy attractive field. The existence of energy in a void doesn't affect the void in any way. "

If you can control/offset gravity then surely you could offset inertia or G forces.

Have you seen the new NASA concept where the spaceship warps space in front and behind it, in effect surfing a space warp bubble and bypassing the light speed barrier.

And remember the idea that gravity is a local distortion in space time, sounds a bit like a warp drive is creating a gravity field like effect.

I have this belief that gravity can move faster than the speed of light. what makes me think this is that light can not leave a black hole it is trapped there because gravity is moving faster than the light, so that tells me that if we can make our own gravity we could break the light speed barrier.

Gravity and inertia are two totally different forces. A two-ton rock in space would have no "weight" but its mass is still the same as it was on Earth. On Earth, you couldn't move a rock that big by hand but in space, you could. Once it was moving though if you get between it and a large nonmoving object it will still crush you.

Gravity is the force of attraction that exists between two bodies whereas inertia is a force that has to do with the movement of mass, both its resistance to start moving and the resistance required to stop it. In order to control gravity, we would need to find a way to block the attraction of objects and understand exactly what that attraction is and what it is caused by. To negate the effect of inertia we would need to somehow lock matter in place in a movable but contained space at an atomic level. With something like a force that wouldn't allow your matter to move, you could move the contained space with as much speed as you wish.

By blocking the attraction in all directions except the one that you wish to go you would speed away in that direction. By controlling the balance you could control the acceleration level and keep it comfortable. A constant one G acceleration would reach light speed in about a year. With some sort of inertial dampener, you could greatly reduce that time. Even this though wouldn't make travel between stars a very fast trip. All that means is that to make a 10 light year trip you would still take about 10 years to make the journey.

In the end, you need a way to offset Gravity, find a workaround for inertia and figure out how to survive the transition to a speed above light speed if it is possible to do. Each step is, under our current understanding of physics, a different force. We can hope that some form of unified field theory would clear the fog of all this and offer us "loopholes" or "exceptions" to all of this. We need a new "E=MC2" type understanding for this to happen I think.
