Can gravitation turn inverse?

The old theory about the Big Bang as an event where gravitation turned inverse makes gravitational waves more interesting than nobody expected. The idea is that gravitational waves are wave motions that source is hypothetical gravitons. When gravitons send wave motion called gravitational waves those waves impact each other. 

If the energy level of those impacting waves is the same. They are forming the standing wave. The height of the waves is the energy level. And the energy level continues growing until the standing wave collapses. And that thing can explain why gravitation is so weak. 

So if we think like this, then antigravity or pushing gravity can be done by gravitational waves colliding with each other. They form a stagnant gravitational wave, which sooner or later collapses. And then those collapsing stagnant gravitational waves make a gravitational pushing effect. 

Was the Big Bang gravitational wave that collapsed? 

In some old theories, the Big Bang was a result of the case when gravitation turned inverse. So how can gravitation turn inverse? The idea is that gravitation is wave motion like radiowaves or visible light. 

The wave motion or superstrings that travel through space can impact each other. In those impacts, the stronger part of wave motion continues its journey. And the lower energy wave motion will melt to part of that stronger wave motion. 

When something turns wave motion around that turns inverse. That thing means that the wave motion's direction can change. There is the possibility that at the point of the Big Bang was a standing gravitational wave that just collapsed. 

And that collapsing gravitational wave motion would push the superstrings around it away from their direction. And if those superstrings existed before the big bang. That collapsing standing gravitational wave pushes those superstrings out from their direction. That thing causes impacts and the wave-particle duality affects those superstrings. 

In the case where the power of impacting wave motions is the same that thing forms the standing wave. The wave or energy level grows higher and higher. Until this standing wave collapses. Same way as other waves gravitation can form standing waves. So in the Big Bang, the thing could be that the gravitational wave collapsed. And that thing turned the direction of the gravitation waves.
