Indications of its presence took so long to get here it may already be gone.
So how do black holes die?
The farther back in time an object is, the more RED SHIFTED it appears.
Until it eventually becomes INFRA-RED and we are unable to view it with our eyes and must rely on infra-red sensors and cameras to detect it.
Now, if MY theory is correct, we should be able to see this same object in the exact opposite direction COMING AT US.
It would be extremely BLUE SHIFTED into the ultraviolet or beyond and we would be unable to see it without the use of ultra-violet detectors and cameras.
The ultimate “What GOES around, COMES around!”............................
