------------------------------------ 2190 - Between Physics and Astronomy
-
- Humans live right in the middle between Physics and Astronomy. We are at the center of all possible sizes in the Universe. We are at the middle of the lifetime of Earth and the Sun. We are at the center of our visible Universe.
-
- Half of our future already exists, it has just not arrived yet. Everything we see happened sometime in the past. The sunlight bathing our environment is already 8 minutes old.
-
- This is our Universe. It exists in all possible sizes. The biggest sizes and the smallest sizes both end up as Blackholes. We usually think of Blackholes in astronomy with bodies that have millions and billions solar mass. However, the smallest possible size is in Physics where Relativity allows a maximum mass to be crammed into the smallest size before disappearing into a Blackhole.
-
- The smallest possible size is 10^-33 centimeters and is called the Planck Length. 10^-33 centimeters is a decimal followed by 32 zeros then a 1 centimeters. On the other size extreme the farthest we can possible see in the Universe is the Cosmic Horizon which is 10^28 centimeters distant. Beyond that distance light has not reached us yet. Humans are right in the middle size at 10^2 centimeters.
-
------------- 10^30 centimeters ----------- the Cosmic Horizon, edge of the Observable Universe
-
------------- 10^25 centimeters ----------- Distant Quasars
-
------------- 10^20 centimeters ----------- Galaxies, star constellations
-
------------- 10^15centimeters------------- Solar System
-
------------- 10^10 centimeters ----------- Sun
-
------------- 10^5 centimeters ------------ Earth, highest mountains
-
------------- 10^0 centimeters ------------ humans, insects, animals, whales to mice
-
------------- 10^-5 centimeters ----------- bacteria, DNA
-
------------- 10^-10 centimeters ---------- atoms, hydrogen to iron
-
------------- 10^-15 centimeters ---------- atomic nuclei
-
------------- 10^-20 centimeters ----------- Dark Matter
-
------------- 10^-25centimeters ----------- ???
-
------------- 10^-30 centimeters ---------- Planck Length
-
- Physics changes as we go from the smallest size to the largest size. When we get to the size of atoms the Physics is Quantum Mechanics. Atomic particles become waves with probabilities of position and motion.
-
- Physics changes again in Astronomy with the very largest and fastest requiring the use of Relativity Theory to account for the bending of space and time. We humans are happy with the Newtonian Physics as long as we stay in our size scale. Stay in the middle where it is safe.
-
- Every living organism on Earth is descendent from a single ancestor and we all share the same genetic material, DNA. This same code in DNA’s information turns proteins into living organisms, from bacteria, to trees, to humans.
-
- The cells of all these plants and animals are all the same size, 10^-4 centimeters, regardless of the size of the plant or animal. There is a blood vessel connected to every cell in an animal’s body. This network of blood vessels connected to the heart is a “fractal”.
-
- It is a circulatory system that looks the same regardless of what size level it is viewed. Most all mammals get the same number of heartbeats in their lifetime, about 1,500,000,000 heartbeats. 80 beats per minute times 36 years is 1.5 billion heartbeats. Modern humans are getting twice that, getting to 72 years.
-
- The average American consumes his weight in resources every day. The human population has grown from 1 billion to 9 billion in the last 200 years. This exponential growth and consumption of resources must end, one way or another. And, this change needs to occur in our present generation, putting us in the middle of history as well.
-
- Right and Wrong on our moral compass points “ right” that promotes the welfare and survival of the group. “ Wrong” points to self-serving behavior at the expense of others. God is represented by our direction not our destination. The goal of education is not to be educated, it is to do something.
