Q

When anything dies, whether plant or herbivore, carnivore or parasite, what happens to it?

A

It is eaten by scavengers like beetles, or it may decay eaten by bacteria and fungi. Yet again, the scavengers are powered by the sun.

Q

What is Solar energy transference?

How does it give plants and animals power?

A

All energy comes from the sun and is reused in different forms. The green leaf is a solar panel, absorbing the electromagnetic radiation (ER). The plants are eaten by herbivores (plant eaters). The energy is passed to the herbivore. The herbivore uses the energy to fuel their muscles as they walk, graze and fight. Then comes the carnivore to eat the herbivore. The energy is passed on yet again. Other animals, parasites, feed on the living bodies of both herbivores and carnivores. So now the insects are powered by the Sun.

Q

How does Solar Energy from millions of years ago, power our civilization today?

Ref: Magic of Reality. P. 140

A

Many plants and animals are not eaten but biodegrade. Over great amounts of time they become coal, oil and natural gas. These modern fuels power our cars, ships, trains etc. All that heat and energy came originally from the Sun, via the green leaves of plants that lived over 300 million years ago. [Think about this next time you gas up your car!]

Q

How does the Carbon Dioxide that the tree leaves drink in get released back into the atmosphere?

A

When cold weather comes, the leaf dies and falls to the ground. As the leaf degrades, it releases the CO2 it drank in when the leaf was young and new. The CO2 merges back into the atmosphere.

Q

If we claim that all our energy comes from the Sun, what about the Water Wheel’s energy we have used for power for hundreds of years?

A

Even all the water wheels energy came from the Sun indirectly from snow, ice and rain in the mountains and the formation of rain clouds all caused by the sun. [It is mind boggling how much energy we blindly use that is only possible because of the Sun.]

Q

Why was there never was a first person?

Caution. This is an Esoteric question.

A

Never was a first person because evolution takes millions of years. Our ancestors were Gibbons. It took a lot of evolving from Damaged DNA and replicating to evolve into the Hominid. Then the process repeated again to go from the Hominid to the Homo Sapien.

Always remember we started out as star dust, just like the Periodic table of elements. So we have come a long way.

Q

Can we see the elements around us?

A

An atom of gold is the smallest we can reduce this atom and keep its identity as an atom of gold. Most of the substances we see around us are not elements, but compounds. A group of atoms joined together to make a compound is called a molecule.

Q

Colon Cancer in African Americans.

A

African Americans are twice as likely to get it than a white person. Plus those African Americans who do get it are twice as likely to die from it.

MN: This is because of the Neanderthal DNA. Whites have about 1.5% and African Americans have the lowest on record at about one half of a percent. Asians have roughly 2.0%.

Q

One light year is about how many miles?

A

One light year is about 6 Trillion miles.

19
Q

Does a nuclear submarine ever need to refuel?

A

A nuclear submarine refuels every 20 years.

20
Q

How sensitive is the sonar on a modern day submarine?

A

A modern day submarine can isolate and detect a ship’s propeller 3,000 miles away, the width of the Atlantic ocean.

21
Q

Do we humans give off invisible light?

A

Yes we do. It is Infared and it just is invisible to us humans. Reptiles like a snake can see it plain as day.

22
Q

How many dimensions does Space time have?

Note: You need all the dimensions to meet someone for coffee.

A

Space time has four dimensions.

H = Height above/below ground

L = Longitude

Lat = Latitude

Time = Time you meet.

23
Q

Since energy cannot be destroyed or created, what happens to our energy?

A

All energy is borrowed, then you must give it back. Our energy disapates as heat.

For a leaf on a tree. When the leaf falls off the tree and it turns brown and dries up, it finished giving its energy back to the universe.

24
Q

Is diet soda or any sugar substitute bad for us?

A

Yes. Sweetened drink = 3 times the chances of dementia and stroke.

Q

Deep Sleep. Ref: NBC News 5/29/17

As an infant we spend 40% of sleep time in deep sleep.

How much time is spent in deep sleep when you are age 80?

A

At age 80 your deep sleep is reduced to only 5%.

26
Q

Gravity does not pull us to the ground. We simply fall through curved space along the path of least resistance.

The presence mass of the Earth causes space to curve and distort. The reason we have gravity on Earth is because the Earth is bending the space around it.

Q

Researchers have long been seeking a way to diagnose Alzheimer;s disease in its earliest stages, before any symptoms appear.

By the time memory loss becomes apparent, damage to the brain associated with Alzheimer’s may already have been occurring for as long as 20 years!

The Brain’s offactory bulb which is involved with the sense of smell are among the first brain structures to be affected by Alzheimer;s.

A

Older people who cannot quite place odors, for example lemon or spearmint, paint, gasoline, etc. are in their early stages fo Alzheimer’s.

“If we can delay the onset of symptoms by just five years, we should be able to reduce the prevalence and severity of these symptoms by more than 50%.

Q

Why is time travel impossible?

A

[MN: The reason time travel is impossible is because time is a logical construct and not real. Time only exist in our human brains.]

Q

The United States for many decades lead the world in manufacturing.

Why did we lose so many manufacturing jobs?

A

87.8% of Manufacturing jobs lost in the U.S. between 2000-2010 were the result of automation and improved technology.

REF: Time mag. 11/13/17.

Q

Coal mining. This year, 2018, almost all electricity is generated by burning coal.

1) Isn’t this going to increase air pollution?
2) If we are burning such massive amounts of coal, why are all the Virginia, tennesse and other nearby mines shut down and the people out of work?
3) Why aren’t we using nuclear power plants to make the electricity instead?

A

1) The coal we use is from the Western mountains and it burns very clean with almost no pollution. We have enough coal in the West to mine for another 80 years!
2) Because the Western coal burns very clean and the Eastern coal mines burn extremely dirty and cause super pollution.
3) Because of earthquakes, tsunami, terrorist and just accidents in general, it is not worth the risk of having a meltdown.

32
Q

How strong is the Sun’s gravity?

A

The Sun’s gravity is 28 times the gravity on Earth.

33
Q

Do we lose most of our immune system as we pass our 60’s and onward?

A

Diminishing immunity with age

Beginning with the sixth decade of life, the human immune system undergoes dramatic aging-related changes, which continuously progress to a state of immunosenescence. The aging immune system loses the ability to protect against infections and cancer and fails to support appropriate wound healing. Vaccine responses are typically impaired in older individuals. Conversely, inflammatory responses mediated by the innate immune system gain in intensity and duration, rendering older individuals susceptible to tissue-damaging immunity and inflammatory disease. Immune system aging functions as an accelerator for other age-related pathologies. It occurs prematurely in some clinical conditions, most prominently in patients with the autoimmune syndrome rheumatoid arthritis (RA); and such patients serve as an informative model system to study molecular mechanisms of immune aging. T cells from patients with RA are prone to differentiate into proinflammatory effector cells, sustaining chronic-persistent inflammatory lesions in the joints and many other organ systems. RA T cells have several hallmarks of cellular aging; most importantly, they accumulate damaged DNA. Altered metabolic patterns provide opportunities to therapeutically target the immune aging process through metabolic interference.
At birth the immune system is equipped with an enormously diverse repertoire of antigen-reactive T and B cells, all of which are so infrequent that they cannot protect the host. Thus, as humans age and are exposed to infectious organisms and cancerous cells, antigen-specific lymphocytes need to expand massively in frequency and switch from a highly proliferative naive cell into a less proliferative effector and memory cell. Massive clonal expansion and persistence of antigen-selected cells for decades impose enormous proliferative pressure on immune cells, rendering the immune system highly susceptible to the aging process.
Aging is associated with several morbidities that finally lead to organ failure and death. With progressive deterioration of protective immunity, older individuals become susceptible to cancers and infections (Table 1). Interestingly, aging is also associated with increased incidence of inflammatory disease, most notably cardiovascular disease (1). Many of the degenerative diseases of the elderly, such as Alzheimer’s disease, Parkinson’s disease, and osteoarthritis, have a strong component of tissue-damaging inflammation. Similarly, production of autoantibodies is much more likely to occur in older individuals (2). In essence, immune aging is associated with declining protective immunity combined with increasing incidence of inflammatory disease.
