The Discovery of Pulsar Stars

Leave a comment

Neutron stars were thought to be preposterous when first suggested until 1967 when scientists used radio-antenna telescopes to map the universe. 3 pulses would be unusual, 4 pulses would be phenomenal, but scientists had received pulses from certain parts of the universe 24 hours per day, 7 days per week for months on end. The reason the pulses occurred was because every rotation of the neutron star causes energy to swipe past Earth exactly how light from a lighthouse sweeps light onto the oceans. Scientists first thought the pulses were from aliens until they proposed that the new star had to be denser than any type previously discovered, being the size of a planet but with the power of a star. Astronomers named these new stars “pulsars” and investigated continuously until 1 year later when they found a pulsar, burried deep within the remains of a super local, the pulsar known as the “Crab Pulsar” which is the closest pulsar to Earth. Interestingly, Swiss astronomer Fritz Zwicky had mathematically proven this phenomena 80 years prior but was labeled a hack for his wild theories

The Reason Human Beings Evolved to Become Bi-Pedal

There is evidence that between 6,000,000 – 10,000,000 (6 million – 10 million) years ago, grasslands expanded across landscapes, creating vast open savannas, whilst tall grasses continued to remain dominant within wetter environments. These novel environments influenced the movement and adaptation of early human beings. It is theorized by scientists that human beings walked out of these evolving landscapes and adapted to the ground as humans were not evolved and/or adapted to take advantage of tall grasses the way other species are (e.g. snakes, mice, large cats etc.). It is also theorized by scientists that human beings needed to stand upright because the forests around them were thinning and with that, the canopy disappearing, making it virtually impossible to move from treetop to treetop as time moved forward. With the discovery of the hominid Anamensis, it is now clear to scientists that the tree of human ancestry follows its evolutionary order from Australopithecus Anamensis 4,200,000 (4.2 million) years ago, to Kenyanthropus Platyops, to Homo Habilis within the past 2,300,000 (2.3 million) years, to Homo Erectus, and finally to Homo Sapiens, the species to which modern day human beings belong to. Anamensis allows scientists to definitively state that bipedalism occurred 500,000 years earlier than what was previously believed as the tibia bone from Anamensis clearly demonstrates that Anamensis walked upright on both legs

How Plants Produce Food Via Photosynthesis

Leave a comment

If a leaf is magnified 1000x, green bacteria like structures can be observed, referred to as “chloroplasts,” which are packed into virtually every cell of a plant. These chloroplasts behave like bacteria, retaining their own deoxyribonucleic acid, and are only 5000ths of 1 millimeter (0.005 millimeters or 5 micrometers) in diameter. It is inside chloroplasts that photosynthesis occurs. Photons, which are tiny and rapid moving particles of electromagnetic energy (e.g. rays of light), are harvested upon the surface of the plant’s leaves, where they then enter the plant’s cells and are absorbed by the light harvesting complex located within the chloroplasts themselves. It is here that the photon is leveraged to drive the photolysis reaction, which is to split a water molecule and release oxygen, electrons, and hydrogen ions, fueling the energy transfer mechanisms that ultimately convert carbon dioxide into sugars for the plant’s growth and survival

The Reason Mercury’s Orbit Around the Sun Appears Retrograde From Earth

Leave a comment

Albert Einstein’s Theory of Relativity can be proven because of how Mercury orbits the Sun. Isaac Newton correctly explained how and why planets orbit the Sun, but because Mercury is so close to the Sun, it orbited its center star 7% faster than it should have therefore Mercury is close enough to the Sun that its space-time path is warped because of the mass of the Sun and this warping causes Mercury to orbit faster than planets further away. For many decades scientists hypothesized there was another planet, unseen yet, which gave Mercury an extra push. This additional planet was prematurely named “Vulcan”, which was in vain because no such planet ever existed. It was also theorized that cosmological dust gave Mercury its extra boost or that an unseen asteroid or asteroid field was helping Mercury along. It wasn’t until Albert Einstein proposed that all matter cuts through both space and time, following a curve, that the catalyst could be definitively proven. If a sphere rolled along a table and suddenly hit a dip, it would speed up and change its trajectory. This is essentially what occurs within space-time and is the reason Isaac Newton’s Universal Laws of Gravitation don’t quite fit with Mercury. Mercury is close enough to the Sun that its space-time path is warped because of the mass of the Sun and this warping causes Mercury to orbit faster than planets further away. It is not only Mercury which does this; any planet or body near its host star will orbit slightly faster than planets or bodies further away. Although it is impossible to visually see the curvature and bending of space-time, it can be definitively proven because of the way large bodies of matter affect smaller bodies of matter due to the mass of each body

The Lush Forests of Australia and Antarctica During the Mesozoic Period and the Reason Antarctica Became Cold

Leave a comment

Both Australia and Antarctica were once fused together as part of the supercontinent Gondwana, neither being an arid and hot landscape nor a cold desert but instead a vast and lush forest, larger than the Amazon Rainforest, spanning thousands of kilometers in size. The reason Antarctica is no longer temperate and forested is because in contrast to most shorelines which disrupt and disperse ocean currents upon contact with the coastline, the waters around Antarctica encircle it unobstructed, forming the Antarctic Circumpolar Current after the Drake Passage opened 34,000,000 (34 million) years ago. Because there is no land to stop this flow of water, it forces the current to become stronger and deeper over time. The Antarctic Circumpolar Current cut the continent of Antarctica off from the warm waters of the north, a thermal isolation further exacerbated by decreasing carbon dioxide levels over millions of years. In a mere 1,000,000 (1 million) years during a rapid cooling phase, although the full shift took tens of millions of years to complete, Antarctica transitioned from an appearance which resembled Australia during its wetter, forested period of the Cenozoic Era, to become a frozen tundra, virtually uninhabitable by humans until the mid 20th century, due to its subzero temperatures which consistently remain far below any other location upon Earth, as well as being locked in by vast ice sheets which formed 14,000,000 (14 million) years ago

The First Human Beings to Migrate to North America

1 Comment

The first people to arrive in North America are suspected to have arrived 15,800 years ago. Sea levels were much lower because of polar ice caps being frozen, which allowed modern day Siberia and Alaska, United States of America, to be connected. How migration occurred is still debated, with some scholars hypothesizing that walking whilst hunting large mammals was the most likely way, while others propose that the indigenous people of North America hunted along the shoreline using maritime skill sets and travel vehicles. 10,000 years ago, the ice sheets receded northbound allowing for civilizations to domesticate northern British Columbia, Canada

The Problem With Super Massive Black Holes

Leave a comment

Super massive black holes have a fundamental problem in that not enough time has passed since the creation of the universe to account for their massive size. This acute time crunch is because the universe has a finite value of only 13,700,000,000 (13.7 billion) years. It is theorized that the reason super massive black holes can become larger than what time permits is because they have a colossal head start due to the fact that they may be birthed directly from a cloud of gas, a phenomena referred to as “direct collapse”. These molecular clouds collapse under their own gravity, and as they collapse, fragmentation occurs as more densely packed areas collapse more quickly. Nuclear fusion begins next and a star is thus created. If a giant gas cloud collapses without making a star, it would form a gas disc instead, allowing the mass to flow into the center very rapidly, creating a black hole instead which is essentially a vortex upon an immense scale

The Reason Life Upon Earth Migrated From the Ocean Onto Land

Leave a comment

Billions of years ago when the first living organisms started harnessing the energy of the sun through photosynthesis, they began producing a waste product which was oxygen. When oxygen rises high up into the atmosphere, it transforms into ozone which is why the Earth has a thin protective layer of ozone which alongside the magnetic field, helps protect the Earth from the violent ultraviolet radiation spewed out by the sun. As plants, microbes, and fungi migrated from the water to land, even more oxygen was produced, extending the ozone layer to become much more formidable. This was the catalyst for life migrating onto dry land which occurred 450,000,000 – 500,000,000 (450 million – 500 million) years ago during the Paleozoic Era, specifically during the Ordovician and Silurian periods

The Condition of the Earth After the Chicxulub Asteroid Collision Which Caused the Extinction of Dinosaurs

Leave a comment

Immediately after the Chicxulub Asteroid collided with the Earth, heat from the fireball produced reached temperatures of 5500 degrees Celsius and produced a shockwave which broke the speed of sound, causing gale force winds equivalent to a hurricane. Everything within 965 kilometers was instantly decimated. Within 11 minutes of impact, the sky began to darken as debris which had been pushed up into the atmosphere started to settle back down. As these small spheres the size of a grain of sand descended back down to Earth, they heated up upon re-entry, identical to that of an asteroid, which provided the illusion of billions of simultaneous shooting stars. The energy produced during this re-entry barrage of heat was more intense than the sun for a brief period of time and made the sky glow red, as if it was comprised of liquid magma. This debris reflected heat back towards the Earth and effectively caused the Earth to act as an enormous radiator. To add to this damage, wildfires began sprouting up due to the intense temperature which caused heat and smoke to fill the atmosphere, compounding the damage already done. Strong winds helped perpetuate these fires and because so much of the Earth was affected, it only took a few hours to become globalized, engulfing the entire Earth in a mass fire which burned hotter than a regular fire due to the inability to dissipate heat sideways. In addition to this, gypsum which contains sulphur, blocked the sun and cooled the Earth over the long term. Gypsum had a seismic effect upon the world’s oceanic ecosystems as ocean acidification occurred due to sulphuric rain being produced by the gypsum within the atmosphere. The reflecting of the sun caused 75% of all plants to die as the Earth only received as much light during mid day as what is present during a cloudy, moonless night of the modern day

The Largest Mass Extinction of Life Upon Earth

Leave a comment

There have been 5 mass extinctions throughout Earth’s tumultuous history. 99.9% of all species which have ever lived on Earth have gone extinct. 252,000,000 (252 million) years ago, Earth suddenly turned toxic to life. Nearly 96% of species worldwide, rapidly became extinct, a period referred to as the “Permian-Triassic Extinction Event”, and less often called the “Great Dying”. This mass extinction was caused by the eruption of super volcanos, leading to the land drying up, the ocean acidifying, every forest dying, and nearly all plant life perishing. Everything alive today is descended from the species which made it through this age
