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 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 First Person to Theorize How Stars are Situated Within the Universe

Prior to the 16th century, it was believed that the Earth was the center of the universe with a belt of stars which rotated around it, exactly the same way in which planets orbit the central star of any solar system. These stars were believed to be fixed in their position as the constellations observed upon Earth do not alter greatly in their position or intensity in terms of what the human eye can perceive. Thomas Digges was the first person to propose that the stars are placed at different distances and in different positions, not in a ring of stars which stayed fixated, but rather in an infinite universe as distant points of light. Digges built upon the work of Nicolaus Copernicus by changing Copernicus’ original visual sketch of the planets and their orbital paths in that he removed the stellarum fixarum meaning “fixed stars” in Latin, and built a model in which stars were completely different in their distance relative to the Earth, with brightness controlled by how far or close a particular star was in proximity

The Rationale as to Why Scientific Fact is Often Referred to as “Scientific Theory”

Leave a comment

The term “theory” placed behind suffixes of large theories like gravity, evolution, and special relativity (e.g. the Theory of Gravity, the Theory of Evolution, the Theory of Special Relativity etc.), doesn’t mean “theory” in the traditional sense. During the 20th century, Sir Isaac Newton’s Laws of Motion began to break down within the theories own borderlines as physics progressed further and further to answer continually larger and more complex questions. As a direct result of this, a grander, more encapsulating law was required to explain certain phenomena (e.g. the reason the sun has a corona of light bend around it during a total solar eclipse) which is why Albert Einstein’s Theory of Relativity is so immensely important, as it explains such phenomena after which Newton’s laws begin to break down (e.g. Newton’s ability to predict planetary orbit but not explain why such a function occurs in nature etc.). Eventually the international scientific community unanimously agreed that laws should not be named as such because they may not remain laws in the long term, as there may be concepts outside of them which help explain both the supposed law itself as well broader phenomena outside of the suppositional law. The term “theory” was utilized to replace the term “law” because something scientific which can change over time, is not or was not truly a law to begin with. The term “theory” is used in the connotation of an idea which accurately describes a phenomena and empowers an observer to accurately predict what they have yet to observe. An idea isn’t genuinely a “theory” until it’s supported by empirical evidence, before which time it remains as a “hypothesis”

The First Usage of Digital Animation (Computer Generated Imagery) Special Effects in Film

Leave a comment

The first ever computer generated sequence in a movie occurred in Star Trek II: The Wrath of Khan which lasted for 60 seconds and is referred to as the “genesis scene”. The scene includes a retinal scan of Captain James Tiberius Kirk as well as a planet being hit by a missile which then creates a stable environment for life. Over 50 software programs were written to accomplish this task and the creators of the sequence went on to form the digital animation company Pixar

The Early Formation of Earth 

Leave a comment

During the early days of the solar system, dozens of planets orbited the sun. It is thought that these planets collided and with this collision came intense heat which melted and welded rocks and minerals together. It is theorized that Mercury was only hit once hence it’s small size, Mars not at all, Venus 8x, and Earth 10x primarily because Earth it is the largest of the rocky planets. The last impact towards Earth is thought to have occurred 4,500,000,000 (4.5 billion) years ago which gave Earth its iron core; the lighter debris floated back above Earth and rotated around it which gave Earth rings similar to Saturn. Scientists now know that Earth was hit by rocks which came from Mars. It is thought that primitive microbial life would be able to withstand the journey from Mars to Earth. Earth had enough gravity to hold its oceans which allowed for constant changes in weather. It is thought that life began on Earth 4,300,000,000 (4.3 billion) years ago and that life became sophisticated 2,800,000,000 (2.8 billion) years ago. Despite the Earth being hit 6x catastrophically which was once thought to have sterilized all life, primitive life forms lay dormant in suspended animation within the salt rock which was produced from the immense heat during each catastrophic event. The microbes lay waiting until conditions became more favorable at which time they started reproducing and thriving. Scientists tested this first hand by drilling into salt rock which was created during a catastrophic event to release 200,000,000 (200 million) year old sea water which held tiny microbes called asilospermians which were reanimated when left within a nutrient rich solution for 4 months

The Protoplanet Theia Creating the Earth’s Moon

1 Comment

The protoplanet which hit the Earth and created the moon is referred to as “Theia”. When Theia hit the Earth, its core fused with the Earth’s core sending enormous amounts of liquid rock into orbit. Because this liquid rock was in a magma like state, it was very easy for it to coalesce and from the moon. The collision changed Earth’s trajectory as a planet because metals like iron were released from the planets core, resetting Earth’s basic chemistry. Gasses like methane, carbon monoxide, and hydrogen, seeped into Earth’s atmosphere, gasses which were the building blocks of life. During the 1950’s, American chemist Stanley Miller carried out a classic experiment which included creating a cocktail of these gasses and simulating life on Earth by introducing electricity. What emerged was a film of brown slime, full of amino acids, the raw material of proteins, created by nothing but the very gasses already present on Earth. During the cooldown of the Earth after the collision, water vapor condensed to form oceans, oceans which were tidal by nature due to the moons gravitational pull. Chemicals found within the early oceans were aided by the moon as the moon pulled upon the Earth creating low tides which in turn were introduced to ultraviolet radiation from the sun as the sun’s heat evaporated the remaining water within those tidal pools. This constant wetting and drying of these tidal pools was the catalyst which created ribonucleic acid, complex molecules created by very simple materials under very simple conditions

The Possibility of Terraforming Mars

Leave a comment

In order to terraform Mars, scientists have theorized that by blasting the polar ice caps on the north and south poles of the planet with lasers, the ice could be melted, turned into water, and used to grow vegetation. Terraforming has been successfully performed in the past, as 1600 kilometers off the coast of Africa is Ascension Island, a place in which nothing grew or lived (as far as scientists are aware of) because there was no fresh water or vegetation due to the top soil being prone to volcanic activity. Charles Darwin visited the island with his good friend Sir Joseph Hooker. Darwin and Hooker terraformed the destitute island by introducing approximately 220 different plants, transplanted by ship, on a Noah’s Ark of sorts. The experiment worked. Ascension Island is now home to hundreds of plant species and the lifeforms which go alongside vegetation
