A space ship using gravity wave shield.

[Pepper1968]

Once we have discovered a type of wave and we have observed its properties we have been able to block it and negate its effects. Water waves, we build a concrete wall, light waves, we build a dark light absorbing curtain and block the light waves and the room gets dark. Sound waves, we build a quite room the point here is that so long as we can observe the type of wave by using our senses or an instrument then we can build a material that can block it. Every type of wave that we have observed, we have been able to block not destroy the wave. So know we have gravity waves and we know they exist and we know that we can observe it and see if we can block it. This is not anti gravity talk you cant destroy energy you can block it and dissipate the wave but not destroy it completely. So i think that it will be possible to block gravity waves in the future now that we know they exist.

A spaceship shaped like a sphere with gravity blocking material would float silently. It will hover and zoom of at tremendous speeds with out injuring its occupants.A car going 100 mph turning a sharp left would push the occupants towards the right and if they are not strapped down would fly out the window or the car would be pulled too causing the car to roll over. That is inertia at work. As you go faster it builds up behind you. A space ship that is being pulled forward by gravity and pulling everything on the ship at the same time would do nothing to the occupants at any speed. Its a sphere with the gravity shielding material and floats. If you want to go forward a tiny opening is made in front and because it weighs zero then a little bit of gravity will move it forward, a larger opening will increase the speed if you want to turn you close the front and open a hole on the right or left. Any where you open a hole your ship would turn in that direction. Because there is no inertia you can travel at break neck speeds and turn with out inertia tearing you and your ship apart. Now, we just have to find the right material to do this. We already know that gravity is a wave and we have been able to block every wave we know of. Water, light, radio,sound etc.. We have blocked them all. Gravity waves shouldn't be so special. This is not anti gravity. Anti gravity means we are trying to destroy gravity. You cant destroy a wave. You can deflect it or reduce its amplitude but not destroy it. A gravity shielding material will negate the effect of gravity but not destroy it.

At present we can detect Gravity Waves, but we cannot generate them. The generators we are detecting are millions of light years away and are generally stars or stellar corpses colliding long long ago in a galaxy far far away.

If we could generate gravity waves, then we could build a Star Trek type of warp drive. The math already shows that. What it doesn't show is how to generate the waves without manipulating more mass than a large planet like we presently do a cell phone.

So it remains in the 'possible but not really' category.

I wish it were otherwise.

Just a bit inf about Gravity Waves)

On 11 February 2016, the LIGO collaboration announced the first observation of gravitational waves, from a signal detected at 09:50:45 GMT on 14 September 2015 of two black holes with masses of 29 and 36 solar masses merging about 1.3 billion light-years away. During the final fraction of a second of the merger, it released more than 50 times the power of all the stars in the observable universe combined. The signal increased in frequency from 35 to 250 Hz over 10 cycles (5 orbits) as it rose in strength for a period of 0.2 second. The mass of the new merged black hole was 62 solar masses. Energy equivalent to three solar masses was emitted as gravitational waves. The signal was seen by both LIGO detectors in Livingston and Hanford, with a time difference of 7 milliseconds due to the angle between the two detectors and the source. The signal came from the Southern Celestial Hemisphere, in the rough direction of (but much farther away than) the Magellanic Clouds. The confidence level of this being an observation of gravitational waves was 99.99994%.

In 2017, the Nobel Prize in Physics was awarded to Rainer Weiss, Kip Thorne and Barry Barish for their role in the direct detection of gravitational waves.
