Using Special Relativity to Solve Cosmic Puzzles

lagoon-nebula.jpgQuantum Fluctuations in the Early Universe
     In the very early universe, there were no particles, only photons zipping about at immense speeds. Those photons must have collided with each other at some point or other, resulting in one of them absorbing the other and therefore creating slightly higher energy densities in certain areas (that is, quantum fluctuations in the early universe). Then energy cooled and the photon concentrations turned into tiny concentrations of mass (which particles later began to form atoms as the universe cooled). As the cosmos expanded, the mass concentrations began to form nebulae as they were spread out over the increasing distances -- and gravity began to draw more matter to them and shrink them into the first stars.

How Particles Acquire Mass

    The mass-energy equivalence states that as a photon is emitted from an electron or any other particle, the mass of the particle increases, because the energy (e) is equal to the mass (m) times the speed of light squared (c). This is because the net mass (the energy + mass) needs to stay the same to prevent a particle from changing, say, from an electron to a quark and so forth. This creates a logical explanation for  how mass is acquired, and the Higgs mechanism is not required.

Animal Poems

Look! I see a shape of tawny,

Its eyes may be kind, but it's fierce and brawny,
On the savanna it blends in so it can hide away,
Never is it seen in the grasses scorched by hot day.


giraffe-sketch-final.jpg




Great and tall, yet in the plains this animal abides,
In the low grasses it can find no place to hide,
Reaching up to 20 feet off the ground,
Automatically no cover is to be found.
For their safety they have to have spots and to run,
Few are caught by predators  -- almost none!
Evidently they're doing alright, for they are still within our sight!





tiger-sketch.jpg
The jungle cat I speak of is striped of orange and black,
In hunting and in swimming it does have a knack.
Gazelles it can easily overpower once it is fully grown,
Each and every cat a stripe pattern has its own,
Roaming in the jungle lightly, never leaving a track!

That there is a green reptile

Under the sea, there's no denial.
Red or brown (green, most often of all)
These creatures swim beautifully, but awkwardly crawl,
Land is where it lays its eggs, but at no other time
Ever does this animal above the tide-line climb.




camel-sketch.jpg


Carrying a pack through the desert dusty gold,
As it has all its days and shall until it's old.
Meandering ever through the dunes of sand,
Ending never, always forward caravanned,
Lumbering always in the desert dunes and folds.



Florida Backyard Birding

pterydactyl.jpg    On vacation in Florida, we saw a surprising variety of wild birds. There were ospreys, great and little blue herons, roseate spoonbills, white ibises, limpkins, bald eagles, moorhens, coots, vultures abounding, sandhill cranes, and all varieties of egret -- great, snowy, and cattle.

    Many of our opportunities occurred close to home, like the pier in Venice, which hosted several anhingas and pelicans. One pelican appeared to have a hurt wing, so we rang the local Save Our Seabirds. They took the pelican and we saw him again (looking better but still favoring his hurt wing) in the Sarasota branch.There was also a church very near to our house with a cross atop it which adornment was the favorite haunt of a bald eagle who evidently hadn't been acquainted with the separation of church and state yet. At the nearby Myakka State Park we saw a stray flamingo flying overhead, along with many roseate spoonbills and some black-crowned night herons as well. Magnificent frigatebirds are rare, but we saw them flying overhead twice (they can be easily identified by their throat pouches, while are still conspicuous when not inflated). The crested caracara is harder to identify, but it flew over occasionally.

  But best of all was the lake back of our house. Almost every evening we would hear our resident pair of sandhill cranes "chortling" across the lake and then flying off to roost. But one day they began to build a nest in a clump of reeds opposite us -- tweaking the grasses with their bills and inquisitively sitting on it. Then, one morning, we found them incubating their eggs, and they never flew away at night again. One chick hatched about a month later, and was quickly nicknamed "Junior." He was at first inside the nest for the most part, but then he gradually began to walk about the lake with his two parents, as viewed with our binoculars. As he grew his appearance changed from that of a small downy chick to a small tawny bird the size of a chicken, with inordinately long legs. One day we decided to go across the lake for a close-up view of the cranes, and we walked across the subdivision to the nest site. They were calmly feeding there, and they showed no signs of being afraid of us. Junior kept running from one of his parents to the other to be fed on the grubs they were digging from the ground, and now and then one of the parents would rise for a moment to see if they detected any intruders, and then resume foraging. The chick gradually grew until his fledging stage arrived -- we would see the two parents walking along the lake and flapping their wings, and Junior following, anxious to keep up with Mom and Dad. By the end, Junior was larger than his mother, and only lacked a red cap to resemble his parents almost precisely.
   The little blue herons and the white ibis seemed to get along relatively well with each other -- we'd see them making rounds across the pond, filing one by one and digging in the Great Blue Heron.jpgpond bed and grass slopes on the bank. Their heads would bob comically up and down. The ibis typically walked much faster than the herons, however, so they would generally end up at least twenty yards away. Juvenile white little blue herons would also sometimes be seen. Little and Great Blue Herons (the latter could sometimes be seen feeding on the lake, occasionally the Wurdemann's or Great White varieties) both flew with their necks bunched up in a comical fashion. Limpkins are relatively rare; they only showed themselves a few times at our pond. They would generally stand near the bank with the herons and ibises.
    Wood storks would sometimes land on the other side of the pond in the late afternoon to feed, and occasionally roost in the tall pines (very seldom, on our side of the pond), but most of the time they would fly off. Also, sometimes we would see a mysterious phenomenon; a group of birds would be flying in the distance, and then they would disappear, often when they went in front of a cloud. We then discovered it was the wood storks flying, and tilting themselves midair until we could not see the black bottoms of their wings.
    Ospreys and eagles frequented a large tree just to the left of our house, and you would sometimes see the ospreys diving for fish, flapping, hovering -- then diving. A juvenile eagle and his parent would sometimes be seen in the tree, attempting to establish authority over a raven that persisted in irritating them. There were regular battles for supremacy (in the bird world, that's the higher branch).
    We also had a chance to view the lives of moorhens, coots, and ducks in detail. In the small-bird world, there was a mockingbird pair who built a nest in our shrub, but theirs was a fussy baby who emitted regular sounds almost like a timer beep when hungry (and sometimes just as irritating). We never got to see much of the chick, who was hidden away in the foliage, but we saw the two parents entering the shrub with food and singing their melodious songs.

Good luck birdwatching and always remember these tips:
-Never get too close to a bird that it might become nervous
-Never at any time litter: a bird might learn to feed in developed places and be run over.
-If you see a hurt bird, always call the nearest wildlife rescue center. Never touch the bird, however.
-Be extra respectful of a bird with a nest.
