# The Advent of Parallax Distance to Measure Immense Distances in Space

Stellar parallax is a measurement technique developed by Friedrich Bessel to measure far away objects in deep space. The process of stellar parallax involves measuring an object from two separate vantage points hinging upon the fact that the object being observed will appear to move a lot more than objects further behind it (e.g. if an observer closes one eye and views their finger in front of a building, and then repeats this act with their second eye closed and the first eye open, the observers finger will appear as though it has moved much further left or right, relative to the other objects behind it). Because Bessel developed a method of calculation to take advantage of this phenomena, astronomers now have the ability to map grand distances with relative accuracy. Bessel worked out that if an observer took an image of a star when the Earth was at either side of its orbit around the sun, it would be possible to observe the star shifting in its position. By knowing how much a star shifts, it is possible to calculate the distance the star is from its observation point on Earth. Bessel surmised that the relatively close star 61 Cygni must be 100,000,000,000,000 (100 trillion) kilometers away from the Earth because of his parallax distance method. This technique unfortunately is severely limited as the diameter of the Earth’s orbit is only 300,000,000 (300 million) kilometers which means that the parallax method can only measure objects up to a factor of 1,000,000x (1 million) the Earths orbital rotation, allowing for a maximum distance of 300,000,000,000,000 (300 trillion) kilometers which is only a tiny fraction of the size of the Milky Way Galaxy or the universe as a whole

# The Evolution of Primitive and Sophisticated Neural Networks

The human brain has 100,000,000,000,000 (100 trillion) connections and 86,000,000,000 (86 billion) neurons, which is more connections and neurons than there are stars in the Milky Way Galaxy. Ironically, the majority of the most successful creatures on Earth do not have a brain; organisms like plants, coral, and jellyfish. The sea squirt is a primary example as it has just 200 neurons, allowing it only to perceive and display simple interaction with the environment by sensing light and moving its flagellum. The sea squirt moves around until it finds a rock, then it dumps its tail and uses those once dedicated neurons for different applications, staying anchored to this spot for the rest of its life. Neurons were originally designed to allow for simple motion and movement, but as evolution progressed steadily, neural networks began to build and design intelligent life which is capable of consciousness and a sense of self but also more abstract concepts like art, mathematics, and science

# Edwin Hubble’s Discovery of the Accelerating Expansion of the Universe

Edwin Hubble was able to work out not only how far a star or galaxy was from Earth, but also the speed at which it was moving away from Earth, a finding which was profound because in a stable universe, stars and galaxies should move away or towards something at random values, however Hubble determined that the further away a star or galaxy, the faster it moves away, which proved that the universe is expanding

# Edwin Hubble’s Greatest Discovery

Edwin Hubble was the first person to notice variability within the luminosity of stars. From this, Hubble was able to work out the distance between the Earth and any star in the universe. This permitted Hubble to calculate how far the Andromeda Galaxy was which is the galaxy nearest to Earth. Albert Einstein did not believe the implications of his own equations and thus added lambda, expressed as “Λ”, to his equations. Lamda was designed to act as an antigravity force, an addition Einstein stated was “necessary only for the purposes of making a quasi static distribution of matter” which means to “maintain the status quo” or to “keep things as they always were”. Once lambda was removed from Einstein’s equations, each one fit perfectly with the observable model of the universe as they account for expansion. Einstein refused to believe the universe was constantly undergoing expansion until years after scientists had confirmed it to be true
