And there was light

The idea of wanting to take a picture of a black hole comes with a tinge of irony. ‘I wonder what it looks like?’ said with the slightest hint of sarcasm. If your mind’s eye can’t muster it, then you are in luck – for the first time in human history we’ve got a snap of this black hole.

Spoiler alert! It’s black and looks like a hole! Maybe no surprise there but for the scientists who have waited 20 years to get a glimpse, they noticed something else about the picture. There was a ring of light around the hole, which looked more like an orange glow. This got me thinking.

8 telescopes positioned around the world were able to build up enough data to create this once in a lifetime image. The light is nothing extraordinary, but I was made more curious when the lead scientist, Prof Heino Falcke, said, “We still have to understand how the light is generated.”[1] Apparently, this 40 billion km (three million times the size of the Earth) cosmic vacuum cleaner’s gravitational pull even drags light into its abyss. And that’s something when you think that light has been around since the beginning of the universe – the Big Bang.

Light was on the scene at the grand opening of the universe, too (sorry, no pictures available!). Steven Weinberg, a Nobel laureate in Physics, describes this epic event: “At about one-hundredth of a second, the earliest time about which we can speak with any confidence, the temperature of the universe was about a hundred thousands million (1011) degrees Centigrade…The universe was filled with light.”[2]

We may not know why light is generated from black holes, but we do know those packets of energy have been around since the birth of this universe. One suggestion for the source of this light has a descriptive beginning that sounds awfully like that of Steven Weinberg, accept it was written some 3 millennia ago.

Maybe you will find it curious that the beginning of the story of the universe by a scientist starts in the same way as the beginning of one of the greatest origin stories – the Bible. This is how the Bible describes the beginning of the universe:

In the beginning God created the heavens and the earthAnd God said, Let there be light,and there was light.[3] Not much difference with how modern science puts it.

Is Weinberg just describing from a scientific perspective what actually happened from a God perspective? Whatever is generating the light from back holes, from the beginning, could light have been the sole creation of a God of light?
