We get the rate at which this thing is expanding. And through the spectroscope we learn about refraction of light. Through the spectroscope we are able to take the light from all those observations. That we have that kind of capability, despite our absolutely negligible magnitude physically, that we can we deal with our minds in such magnitudes and do so quite reliably gives us a hint that human beings must have some very great significance in the scheme. As humanity on board of our planet entered into what it called World War I, the scientists around the world had ways of reporting to one another officially.
Chemists have what they call chemical abstracts.
Chemical abstracts are methodical publications of anything and everything any chemist finds that he publishes information regarding, it becomes a chemical abstract. I with almost a million substances known. By the time we entered World War II, we were well up to 10 million and we've come out of it now, where the figure is really getting to be astronomical. We can't really keep track of the rate at which we are discovering more, just talking about differentiable substances, chemically distinct from one another. One life in the extraordinary numbers of lives there must have been on board of our planet.
