Some things that are difficult to wrap our mind around.
DNA. Every cell in our bodies has a copy of our entire DNA chain. Each species of cell has the knowledge of what part of the dna chain to use as an instruction for positioning and repairing itself. Many Genes do not activate in some species (probably all to some degree) until called upon by the species response to its environment. Slight damage is repairable (we are surrounded by waves and particles that impact us), major damage causes the cell to self destruct and be absorbed by our internal disposal cells. Surrounding cells then divide to replace the cell that died. What is amazing is that millions of cells die and are replaced and yet we remain the same person we were last week, although from a literal point of view we have replaced ourselves throughout our lifetime..
The big bang. Sounds good, but what does it mean? To create Space and Time, to inject a form of energy that condenses when cooled into galaxies, stars, planets, and self aware life form can only be a mystery to most of us. To try to understand this concept we have invented an infinite number of parallel universes which only confuses the lay person.
Distances in the Universe. A light year (the distance light travels in one year), rounded up, is six trillion miles. So far the Hubble telescope has captured light that has traveled 13 plus billion light years. That is 13,000,000,000 times 6,000,000,000,000 (trillion miles), or 78,000,000,000,000,000,000,000 miles..
Sizes in the Universe - The mass and lifetime of our Sun. 200 billion Suns- 200 Billion Galaxies, some Galaxies have 400, 800 Billion stars. In round numbers that means there are up to 160,000,000,000,000,000,000,000,000 stars. There is a Black Hole that is projected to be the size of a Galaxy with a mass of 18 Billion of our Suns.
Cells in our Body - Give or take a few (we are all different sizes) there are approximately 100,000,000,000,000 (100 trillion) cells in the human body. Interestingly enough there are bacteria in our bodies that exceed this number.
Nerves and nerve connections in our brains - 100 Billion Nerve cells times an average of 1,000 connections per nerve cell is 100 trillion connections
Speed of Light - A photon (or quanta) of light begins its journey at 186,000 miles per second. There is no acceleration, no ramping up, just instantly 186,000 miles per second. Since some light has traveled for Billions of years we must be missing something. Like what is it that allows light (as a wave or particle) such instantaneous speed, that in a vacuum can literally travel forever.
Some Other more difficult Things that are hard to grasp -
Direct Killing - How can one group of humans exterminate an entire population of human beings. How can one person be talked into blowing up a bus with children in it. How can leaders assign tens of thousands to their death to make a point. How can anyone in their right mind follow such a leader.
Secondary Killing - How can we as nations permit the death of 11 plus million children every year. How can we continue to pollute and damage our soil and water that will kill tens of thousands every month. What is it that prevents Nations from getting together to assess the challenges to our species survival, cooperating to manage our finite resources. and developing educational and innovative programs to allow our natural creativity and problem solving abilities to discover and innovate.
Population - Our population will increase over the next century at an exponential rate. Predictions go as high as 12.5 billion people. The problem? Such large numbers tap our resources also at an exponential rate. How obvious is it that unless something is done, preferably volunteerism, to stop the exponential rise in population, we will exceed the capacity of our planet's ability to support us. This is the elephant in the room. Lets look at fresh, drinkable water, as well as our total use of fresh water throughout the world.
........ If one person drinks the equivalent of 1 gallon of water per day, and there are 365 days in a year, then we will consume 12.5,000,000,000 times 365 gallons per year equals 4,562.5 billion (4.5 trillion) gallons. this is only drinking water. The US in the year 2000 consumed, on average + or - 1250 gallons per day per person (includes industrial use) . All of this translates (with very hefty rounding) to consumption of 5,715,525,000,000,000 gallons of fresh water per year.
Using slightly different numbers it is projected that by 2025 we will be using 70% of the available fresh water and if by the year 2100 we do hit 12.5 billion people we will exceed the available fresh water by 20 to 40%.
We now have serious conflicts over oil (even wars), how do you see us behaving when we do not have enough fresh water. Of course innovation, pollution control, and sea water may take care of this problem, but, until solutions are found for the entire world conflicts and costs will rise.
There is one element not accounted for. If climate change, warming, does occur the amount of available fresh water will decrease, and some parts of globe will have none.
This is one small case for Global management of resources. Not governance but Global Management.
You can see from this one small example, if things are not to go to hell in a hand basket, each individual must strive to let go of anger, real or imagined threat, and their Ego, to allow global management to work. Crowding, limited resources, not enough land to grow food on, will create an environment ripe for conflict. To prevent this we must all transition to conscious self awareness, letting go of our self image, letting go of our past and fears for the future, and learn how to be in the present where we can apply all of our problem solving skills towards the real issues that will face us all - our species survival and quality of life.
