Without us here to witness, the universe is just pointless physics unfolding.
We are the last generation of humans on Earth!
While Newton seemed to draw off the veil from some of the mysteries of nature, he showed at the same time the imperfections of the mechanical philosophy, so agreeable to the natural vanity and curiosity of men; and thereby restored her ultimate secrets to that obscurity, in which they ever did and ever will remain.
The universe, the whole mass of things that are, is corporeal, that is to say, body, and hath the dimensions of magnitude, length, breadth and depth. Every part of the universe is ‘body’ and that which is not ‘body’ is no part of the universe, and because the universe is all, that which is no part of it is nothing, and consequently nowhere.
A mathematician is an individual who calls himself a ‘physicist’ and does ‘physics’ and physical experiments with abstract concepts.
The velocities and forces involved in anything at orbital altitudes were enough to kill a human with just the rounding error. At their speeds, the friction from air too thin to breathe would set them on fire.
In the beginning, there was physics. “Physics” describes how matter, energy, space, and time behave and interact with one another. The interplay of these characters in our cosmic drama underlies all biological and chemical phenomena. Hence everything fundamental and familiar to us earthlings begins with, and rests upon, the laws of physics. When we apply these laws to astronomical settings, we deal with physics writ large, which we call astrophysics.
Something deeply hidden had to be behind things.
The time is my vehicle & the light is my fuel.
There is a philosophy that says that if something is unobservable — unobservable in principle — it is not part of science. If there is no way to falsify or confirm a hypothesis, it belongs to the realm of metaphysical speculation, together with astrology and spiritualism. By that standard, most of the universe has no scientific reality — it’s just a figment of our imaginations.
