DIMP (dimensionless point)

December 30, 2020

DIMP (more psy phy physics from a sci fi writer.)

Photons – or anything going the speed of light – are outside time (and eternal) and are outside of distance (there is no distance between any two photons.)
They are all, in a dimensionless point = Dimp.

As an object approaches the speed of light:
1. Becomes heavier and approaches infinite mass.
Infinite mass is also infinite energy (E=MC2)
2. Contracts in length.
Speed of light means no length = a point = a dimensionless point.
3. Time slows.
Could it keep going faster it would reach the speed of light and be outside of time and be eternal.
SO if mass could go the speed of light (and it can only approach it now) it would be infinite energy, no length – single dimensionless point, outside of time = DIMP!

UV and its Role in the Origin of Life

UV AND ITS ROLE IN THE ORIGIN OF LIFE.
By Tom Hendricks

Introduction. Life, the origin of life, is more likely to start if it had a 99% chance of starting; then if it had a 1% of starting. So most likely the OOL was 99% likely, not 1%.
For me the turning point to the study of the OOL, is that life is not a fluke, but the most stable chemical reaction to the environment. Though this proves nothing in itself, it may adjust the mindset in OOL investigation, that now seems stuck in a rut!

ULTRAVIOLET LIGHT AND ITS ROLE IN THE ORIGIN OF LIFE. Paper.

Introduction. A number of recent studies suggest that ultraviolet radiation may be a necessary ingredient in the origin of life. Further, one may hypothesize that the daily solar cycle and the Sun’s UV radiation were important in all stages of the origin of life on Earth. Moreover, it is suggested that life can be defined as that chemical reaction forced by the energy cycle of the Sun, under very specific circumstances.

Evidence. In support of these claims are the following assumptions and lines of evidence:

1. The assumption that all stages of the origin of life took place at or near the surface and close to or on land.

2. The assumption that there was a lower solar luminosity, higher UV flux, and no ozone layer in the period of the origin.

3. The assumption that there was a shorter diurnal, day/night cycle, due to the faster rotation of the Earth following the presumed collision that preceded the formation of the Moon.

4. The assumption that chemical selection was for stability under the Sun heat cycle.

5. The assumption that solar radiation far exceeded all other energy available for organic synthesis, including electrical discharges, shock waves, radioactivity to a depth of 1 km, volcanoes, and cosmic rays.

6. The assumption that there were wet/dry cycles that drove phosphorylation of nucleotides and perhaps other condensation reactions.

7. The assumption that there was at first a primitive, environmentally forced, PCR-like replication process of alternating heat and cold that denatured then annealed RNA paired strands. It is assumed that the Sun cycle (day and night) caused a cycle of primitive denaturing and annealing of paired RNA nucleotide strands [and possibly folded (annealed) and unfolded (denatured) nucleotide strands]. It is assumed that this provided a large number of variations of paired RNA strands with variations of properties, the most stable of which possessed the best Watson-Crick (W-C) pairing.

8. It is assumed that instead of a self replicator, there was at first a primitive, Sun-forced replication process. It is assumed that proof reading would at first have been limited to W-C pairing over non W-C pairing for stability. Note also the assumption that paired bases may have better protected the ribose-phosphate backbones from UV damage.

9. The assumption that the first coded information would have been for that molecule which was most stable in the Sun/heat cycle environment. Note: in Watson-Crick base pairing in RNA there are two sets of nucleotide bases: G bonds to C and A bonds to U. It is assumed that Watson-Crick base pairing is more stable in this environment than non Watson-Crick base pairing. And of the two sets of bases, It is assumed that the G-C bonds would have been more stable than A-U bonds because G-C bonds have 3 hydrogen bonds instead of the 2 of A-U. It is also assumed that A-U would have been more stable than non Watson-Crick base pairing. Further it is assumed that high G-C base pairing would have supported more stability than high A-U base pairing. Additionally it is assumed that A-U base pairing would have supported more stability than non Watson-Crick base pairing, or no base pairing at all. It is also assumed that high A-U base pairing would allow for more variation than G-C base pairing, because A-U bonds are more likely to denature in heat and more likely to denature quicker than G-C bonds and thus more likely to anneal with other RNA strands in cooler temperatures. It is assumed that overall the G-C plus A-U sets of nucleotides would promote both general stability with the G-C set, and variety with the A-U set of nucleotides.

10. The assumption that RNA acted as a receptor and transducer of UV radiation.

11. The assumption that there was a cyanobacteria-like lifestyle for the earliest confirmed true organisms so far, and that this earliest remnant of life is very near the likely origin of life.

12. The assumption that there was a pyrimidine dimer impact on the genetic code. It is assumed that because of the high UV during this period, UV-caused pyrimidine dimers would also be highly likely. This further assumes that this would not favor any code with adjacent pyrimidines that would lead to the likelihood of pyrimidine dimers. This further assumes that the most likely first codons would be either purine / pyrimidine / purine, or pyrimidine / purine / pyrimidine; coding that prevents adjacent pyrimidines and thus pyrimidine dimers. Later it is assumed that this would lead to information coding beginning in the 2nd position, or middle position, the most protected position of the 3 base codon and anticodon. It is assumed that this initial coding may have been limited to 2 classes or sets of amino acids; hydrophilic (XAX with "A" in 2nd protected position) and hydrophobic (XUX with U in 2nd protected position). There is also the assumption that there was a pyrimidine dimer impact on tRNA which, it is further assumed, was one of the earliest forms of RNA.

13. The assumption that the Miller / Urey experiments are seen as an illustration of a heat cycle, "energized by a cyclical electrical discharge apparatus to represent UV radiation from the Sun."

14. The assumption that the first mechanism that used sunlight energy to remove hydrogen from water may have been UV radiation on ferrous ions. Magnetite, a mixed oxide of ferrous and ferric iron found in banded iron formations (BIF) may be remnants of that process.

This hypothesis avoids problems in competing theories.

1. The problem that heterotrophic lifestyles rapidly deplete the soup of nutrients, thus forcing an implausibly rapid invention of photosynthesis. Instead it is assumed that life started out on a phototrophic path, rather than having to invent it in such a short span of time.

2. The problem of self replication. It is assumed that RNA would not at first replicate on its own, and would need some kind of environmental energy forcing it to replicate. It is assumed that the Sun cycle would provide planet wide forced energy daily. It is assumed that it would provide stable but variable energy that could force into existence a replicating chemical system by denaturing paired RNA strands in high temperatures, then annealing single RNA strands in low temperatures.

3. The problem of UV as a major detriment to the origin. It is assumed that UV would no longer be seen as a detriment to the origin of life but instead as a necessary component of the origin, and a necessary part of the selection process during the origin.

4. The two problems that hydrothermal vent scenarios have: a. no assumed necessary dry phase component for condensation synthesis; b. no assumed necessary UV component. The Sun is a more stable, longer lasting, energy source than any vent, especially if the origin occurred during part of the long bombardment phase, a bombardment that would have upset the constancy and stability of most vents. Also the Sun does not sterilize the water through high temperatures like the vents do.

5. The problem of how the complex mixture of necessary molecules for the origin of life, came about.

James Lovelock has said this regarding the claim that ultraviolet would have been detrimental to the origin of life: "This belief that ultraviolet radiation is unconditionally lethal to life on Earth has sustained a distorted view of the Archaean … And it is a view still deeply entrenched in scientific thinking. I found it to be common among the scientists who sought life on Mars. I could not help wondering how they could think that there was life on the intensely irradiated surface of Mars and at the same time believe that the land beneath the thick and murky Archean atmosphere of Earth was sterile. How could they fit into their minds two such contrary ideas?"

Conclusion. It is suggested that experimenters in prebiotic chemistry look to how chemicals react to a Sun / heat / UV cycle in ways that lead to life processes as a response to that forced energy.

Particle is a subset of the Wave

October 16, 2020

WAVE OR PARTICLE; Psy Phy Physics from a science fiction writer

Why do I look at waves not particles? Looking at waves, not particles shows the weaknesses and problems yet to be solved in quantum mechanics, also the clues to move forward.

More and more I see the particle as a SUBSET of the wave. The particle is most probably in the crests and troughs, that means it is part of the wave. The particle is almost never in the nodes of the waves. There seems to be some type of duality here where the particle seems more mass like, and the wave, more energy like. Could almost say one is in space time, the other in a dimensionless point.

The quantum world is never cut and dried – so that for me means spin, superposition of waves, destructive interference of waves, virtual particles, magnetic properties, direction of the waves, orbitals, binding energy, charge properties and particle wave duality: they are all going on at once, and everywhere in the atom at the same time (I have a text quote saying that even more eloquently than me.)

Physics speculation: Compare these 3

1. Particles most probably in crests and troughs of waves

2. Virtual particles that pop in and out of existence or quantum fields

3. This quote from Quantum World
In the particle world, events seem to occur at exact space time points, not spread over space and not spread over time. Indeed experiments indicatethateverything that happens in the subatomicworldhappens ultimately because of little explosive events at space time points – events, moreover in which nothing survives. What comes into the point is different from what leaves it.

What is Not Like the Others

September 17, 2020

WHAT IS NOT LIKE THE OTHERS
Which item on the following list does not fit the simple drawing that shows:
PARTICLE/WAVE A,

PARTICLE/WAVE B

And a FUZZY ZONE in between that might be, like a photon, outside of distance and time.

1. Quantum jump where the electron jumps from shell to shell.

2. The Two Slit Experiment where the black band shows where no particles/waves land.

3. Destructive Interference where wave A and Wave B meet, cancel each other, and turn into more kinetic energy.

4. Virtual Particles where particle A and Particle B pop up out of the void, then come together and there is total annihilation.

5. Quantum tunneling. Particle A disappears on one side and materializes on the other side, Particle B.

6. Entanglement where electron A and electron B have entangled properties no matter the distance between them.

7. Charge where Particle A and Particle B with the opposite charge have charge between them.

8 Wave where Particle A and Particle B are most likely in the crests and troughs of the waves, while the probability is high that neither particle are in the nodes of the wave.

9. Wheeler’s Great Smoky Dragon analogy, where A is the head of the dragon, B is the tail of the dragon and the area between is smoke.

Multiple magic, or a single phenomenon

Follow up!
That long list of A – fuzzy zone – B, may also have something to do with cosmological constant and dark energy:

"The estimate of the energy of EMPTY space is 120 orders of magnitude larger than the energy of everything else in the Universe.
Yet something is wrong because that proven fact as is, would lead to a runaway universe pulled apart.

BUT if it is, like photons, outside of distance and time like I’ve suggested, then all that fuzzy zone is not only outside of space and time, but in a single dimensionless point!

Somehow that point is drawn into space time – but how is the question.
