In this course you’ve learned a staggering concept: roughly 95% of our entire universe is in a form that is essentially unknown to us. Given that science has certainly taken profound strides in understanding the universe over the past few centuries, how does this realization affect your view of our state of knowledge?
It is really both interesting and perplexing and the same time. You begin thinking you understand the physics of something and all of a sudden you get the sense that all you know is just a point in a sea of information, which is normally overwhelming for the human mind to grasp.
The fact that we only understand 5% of what the Universe is made of, doesn’t mean that all our accumulated knowledge of astrophysics/cosmology only amounts to 5% of what there is to know, as in quantitive terms, for example, dark matter and dark energy are only two concepts, albeit very important concepts, which if discovered, would allow us to understand approx 100% of what the Universe is made of. So in quantitive terms, it may be that we already understand 98% of what there is to know, if dark matter and energy were the only outstanding issues in cosmology, which they are not.
I already knew some of this but it was great to enhance my knowledge from a professional astrophysicist. Everyday we try to look out in the space and find things that we can not explain. Although we can achieve a giant leap forward if we can connect macro universe with the micro universe. Understanding of Quantum Mechanics will be a next break through in modern physics, which most definitely will open doors to new age of physics and technology all together.
