Our logic can analyse the physicality of existence. But once we cross the physical threshold, logic is completely out of its depth. If we try to understand the universe by going outward, knowing full well it is immeasurable, it is going to be an impossible project. We have no clue where the universe begins, where it ends, and where it's centre is. It can only be an endless pursuit.
Yogic science took another route. It recognised that this little piece of life- the human being, is made under the same laws that govern the cosmos. It is made according to the same principles of creation, a micro cosmos if you will. If you observe your interiority closely enough, you will know how a human being happened. Once you know that, you know by inference how everything happened.
Anyone can see this if they simple look within. If you cut a tree today, it is possible to look into the rings of the tree and talk about the past. It is possible to say when a drought happened in that land, when there was excessive rain, or a raging fire.
Similarly, if you pay attention to the human system with the needed awareness, you can find the very history of this creation inscribed there. Whilst it true you do have a conscious age, the atoms you are made of are billions of years old. They carry a story which you can decipher in the form of vibrations. Whatever has happened in existence is in some way recorded within you, in this very body. If you look deep into yourself as a piece of energy, you can see that the information you carry goes all they way back to the beginnings of the evolutionary process that started with the single celled animal and even further back to the atoms and particles and then to the big bang and beyond.
Whether you call it physics or spirituality, both of them are seeking the same thing, the basis of existence. One is trying to explore the outside and understand it. Another is trying to explore interiority and feel it.
Note: The above is from a book called Adiyogi and is by far the most profound piece I've read. It still leaves us with a lot of blind areas so I will do a part 2 to cover this. Please do let us know your thoughts and questions. :)
