The gravitational wave's memory effect was detected the first time.

A gravitational wave's memory effect means that gravitational waves can transport information. 

If the gravitational wave is like some kind of tornado or roll that travels in the universe. It can carry information. In the 2D models, gravitational waves are like ditches, lower energy areas in the universe that travel ahead. The spring-like quantum structure around the wave transports information. Or, maybe there are energy bubbles or some other structures in gravitational waves that can transport information. And maybe. Those things can help to open a view behind the black hole's event horizon. 

The new observations about the gravitational waves make them more interesting than before. The sensors detected the memory effect in gravitational waves. That means the gravitational waves behave like optical and other EM waves. So gravitational waves can transport information between distances. And that makes those waves interesting. 

On "phys.org" homepages the description of the "gravity wave memory" is described like this: "Einstein's theory of gravity, general relativity, has passed all tests with predictions that are spot-on. One prediction that remains is "gravitational wave memory"—the prediction that a passing gravitational wave will permanently change the distance between cosmic objects." (Phys.org, Detecting the gravitational wave memory effect from core-collapse supernovae) 

That means gravitational waves warp the spacetime. Spacetime is the energy field. That we can call the "Higgs field". The thing is that gravity waves affect the energy flow of an object. The idea or model in gravitational waves in 2D models is that the gravity wave is like a traveling ditch. When a gravity wave travels forward, the energy falls into that ditch. And it takes speed and rises from the back of the wave. The idea is that gravitational waves make energy move. 

When we talk about the distances of the effects of the four fundamental forces or four fundamental interactions we can make the model that all of those four interactions, strong and weak nuclear forces, electromagnetism, and gravity travel in nested waves. The bigger wave carries smaller waves on its shell. Just like when we see smaller waves on the bigger waves at the sea. The reason why we cannot see the long-distance effect of the strong nuclear force is that bigger or higher energy waves cover those small waves below them. 

Gravitational waves are like tsunamis in the universe. They might look harmless if something doesn't pack them. Same way tsunami is harmless when it has space to grow. But when there is no space and a tsunami comes to the coast the bottom of the sea pulls that monster wave up.

 Same way when a pressure wave travels in the deep sea and it reaches the continental shelf that thing pushes the moving water up. Sometimes erupting volcanoes under the sea push the water up forming an open sea tsunami called a killer wave. Same way the gravitational waves can get enormous power when they impact other gravitational waves or some extremely dense energy field.

So, when a gravity wave travels in the universe it transports electromagnetic, weak- and strong nuclear forces. If some energy impulse hits those waves the gravity wave transports it can inject energy to that gravity wave. And that can form an enormous energy tsunami in the universe. 

The thing is that the standing energy doesn't have any effect. But when energy starts to move it takes its effect on its environment. The black hole is like a whirl or bubble in the electromagnetic and gravitational fields. And the black hole is actually interaction. The outcoming energy presses the structure from the outside. 

And the reason why black holes are so special is that their material disks are so large. The outcoming field presses against the event horizon. If we think that the black hole is an empty bubble there some part of the base energy field in the universe is missing which means other energy forms try to fill that hole. 

The idea is that all four fundamental forces are strong and weak nuclear forces, electromagnetism, and gravity have the waveform. And each of them has their own wavelength. The fact is that there is no pure fundamental force in the universe. If we look at the waves at sea we can see that there are also smaller waves on the bigger waves. 

If we transfer that wave model into the electromagnetic or quantum world we can see that in the electromagnetic world there is or there should be smaller waves on the surface of the bigger waves. In this text, the electromagnetic world means the quantum fields. And the model is that the waves of the weak nuclear force can ride with larger electromagnetic waves. 

In the same way, the strong nuclear force waves that the gluons send can ride on the waves of the weak nuclear force. In that model, the fundamental interactions's wave movement form can ride with other bigger waves. That means the strong nuclear force can travel over long distances when it rides with other wave movements. But the other wave movements cover those waves below them.  That thing causes a very interesting model.
