The article for this research is “37.2 Trillion: Galaxies or Human Cells?” by Nicholas Balakar and it appeared in the New York Times. In this article, Balakar poses a question regarding which has a higher number: all of the known galaxies in the observed universe and the number of cells in the average human body. In attempting to determine the answer, he immediately states that both totals would be massive in number and that it would be impossible to reach a precise answer. There are also several unknown factors involved in this question, including the fact that the human body can vary in size a great deal and the fact that the size of the known universe is constantly changing with our ability to observe it. While individual galaxies have been identified at length, our definition of what a galaxy is has evolved over time and may continue to do so. Galaxy derived from Greek galaxias. Galaxies are defined by the National Geographic as:” sprawling space systems composed of dust gas and countless stars.” At the same time, nobody …show more content…
Dr. Bianconi and her team of research scientists utilized this data and rough estimates of the average size of a human cell to determine that there would likely be roughly 37.2 trillion cells in the average human body. Scientists mapped out the average surface area of a human and made calculations based on this finding. For Balakar, this means that there are certainly more cells in the human body than there could be galaxies. In determining the likely number of galaxies, astronomers have simply counted the number of galaxies in an individual section of the universe and multiplied that by the vast volume of space that exists in the known universe. By using this technique, scientists have estimated that there are 800 billion
In Alan Lightman’s, “Our Place in the Universe,” he describes his experiences in the Greek Isles explaining how meek it made him feel to be surrounded by the vast ocean with no land in sight except a small strip of brown in the distance. Great thinkers throughout history, have been exploring the visible variety of shapes, colors, and sizes, though the greatest of these are size, from the smallest atom to gargantuan stars. These massive differences in size change the way we view ourselves in the universe. (470) Garth Illingworth, from the University of California, has studied galaxies more than 13 billion light years away from us.
In the last hundred years we have made enormous progress in studying not our galaxy but ones billions of light-years away. Only a few hundred years ago our world seemed so big that there were areas of the world that had never been charted and people believed that the Earth was flat (and yes for some reason a few people still believe that today). If we continue to make progress at thus rate the universe will actually begin to seem smaller because of how much more we might know.
According to Neal Conan from Talk of the Nation there are trillions of cells growing in laboratories now than there ever were in her
For many year, scientists have been researching and experimenting to understand how life on earth began and what was the turning point. Many studies and research were done in order to answer this question. After many years of research, scientists finally discovered the essence of life to be the cell. In order to consider something alive, the cells in the organism should be able to grow, reproduce, have the ability to process information, and carry out chemical reactions (Freeman 1). Even though cells are small, they are very complex and they are the functional unit in the human body. After discovering the cell, scientists wanted to know what is the structure of the cell. Under a microscope, an english scientist by the name of Robert Hooke was able to first observe the cell under a microscope using a part of a tree (Karp 2). Scientists divided cells into two different categories; eukaryotic cells and prokaryotic cells; each category has specific characteristics that defines each kind of cell. For instance, eukaryotic cells have a membrane bound organelle called the nucleus as well as ...
Are human beings alone in the Milky Way Galaxy? This constitutes one of astronomy’s biggest inquiries of all time. The Kepler Mission was launched in March 2009 to analyze a sector of the Milky Way galaxy in order to ascertain dozens of Earth-size planets within the habitable zone (Jerry 1). By applying the transit method, NASA scientists would conclude the amount of stars containing habitable planets which has revitalized the question of extraterrestrial life. Through the state of the art spacecraft and specially designed methods, NASA has met many of the fundamental objectives and has discovered hundreds of exoplanets. Unquestionably, these discoveries have made Kepler to become one of the most notable NASA missions to date.
Eukaryotic cells have their chromosomes contained in a nucleus. Unicellular orgasisms such as amoebas and yeast, or multi-cellular organisms such as plants and animals consist of eukaryotic cells. Human being consist of approximately 1 billion cells per gram tissue. DNA located in 23 pairs of chromosomes is contained in each cell nucleus. Schleiden in 1838 and Schwann in 1839 made very important discoveries that we consist of cells, and Remark discovered that cells prolifarate through division in 1850. Three decades ago, the molecular mechanisms that regulate the cell cycle and thus cell division was able to be identified. It has been known that these vital mechanisms are conserved through evolution and function in the same way in eukaryotic organisms.
Frank Drake in 1960, consist of the product of seven variables set equal to the variable, N. The equation is N = R* FP ne FL FI Fc L. Carl Sagan breaks down what each of these variables mean in a video. The variable N represents the number of “advanced civilizations” in the milky way galaxy capable of radio astronomy. The variable R* represents the the number of stars in the galaxy. The variable FP represents the fraction of those stars that have have planets around them. The variable ne represents the fraction of those planets that are able to sustain life. The variable FL represents the factions of planets where life exist. The variable FI represents the fraction of planets that have intelligent life. The variable Fc represents the fraction those planets that are able to communicate with technological advancements. The variable L represents the length of time such planets are a technical
Is it dependent, for instance, upon the number of discrete units which comprise the functioning whole?
...uld speculate that all that we hold as real is nothing more than the playful dance of light, light that has no dimension and limitless dimension. The radical implications of Bohm's implicate order take some time to fully grasp, especially for Western minds, but whether Bohm's holographic paradigm becomes accepted in science or not remains to be seen. We must realize that any model is just that, a model. Anyone willing to make the appropriate observations can see for themselves whether any particular claim about the structure of the universe is true or not. No one has to take anybody's word for anything. No scientific claim can be conclusively confirmed, however, because there will always be a more comprehensive theory to follow it, and perhaps disprove it or encompass it. That is evolution of consciousness, and I suspect we will never reach the top of that climb.
Which sounds like a lot but considering the age of the universe that is a blink of an eye. The galaxy should have been colonized many times over by now.
Charles Darwin believed that all life forms have one common ancestor. Because of this belief, astronomers, from the University of Cambridge, have combined their knowledge with biology and archeology to apply this theory to stars in the Milky Way. The team picked 22 stars, including the sun to study. They studied the chemical substances within the stars to see if any were similar. Stars are born from explosions in the gas clouds, if two star have the same chemical compositions then they are most likely from the same gas cloud. Once the families were identified by using the information from their chemical DNA, their evolution was studied.
Cells were first discovered by Van Leeuwenhoek. He coined the term cell. After cells were discovered the cell theory came out which states. All living things are made of cells, cells come from preexisting cells, and cells are the smallest unit of organized life. When Van Leeuwenhoek first discovered cells he described them as looking like monk's cell room. There are two main types of cell Prokaryotes cells and Eukaryotes cells. Eu means true. Eukaryote cells have a true nucleus. Kary means nucleus. Cyto means cell. Prokaryote and Eukaryotes have a nucleus. Pro means before. Prokaryotes came before eukaryotes which means they are primitive. Prokaryotes are bigger than eukaryotes. Prokaryotes are smaller than eukaryotes. Prokaryotes
There are probably more than one hundred billion galaxies. At a distance of approximately 13.1 billion light years, z8_GND_5296 is the most distant galaxy yet discovered. The galaxy appears to astronomers as it was just seven hundred years after the big bang. What’s used to observe galactic phenomena are ultraviolet and x-ray telescopes. An ultraviolet flare was observed when a star in a distant galaxy was torn apart due to the tidal forces of a black hole. X-Rays can map the distribution of hot gas in galactic clusters. No one knows the exact number of galaxies there is, or if the universe has an end. One can travel at the speed of light forever without reaching an edge since the universe is without a boundary and is expanding.
The Universe is a collection of millions of galaxies and extends beyond human imagination. After the big bang, the universe was found to be composed of radiation and subatomic particles. Information following big bang is arguable on how galaxies formed, that is whether small particles merged to form clusters and eventually galaxies or whether the universe systematized as immense clumps of matter that later fragmented into galaxies (Nasa World book, 2013). A galaxy is a massive area of empty space full of dust, gases (mainly 75% Hydrogen and 25%Helium), atoms, about 100-200 billion stars, interstellar clouds and planets, attracted to the center by gravitational force of attraction. Based on recent research, 170 billion galaxies have been estimated to exist, with only tens of thousands been discovered (Deutsch, 2011).
... God is the cause of all things, not astronomical bodies. In his time, Alhazen wrote around 200 books, but since he lived a long time ago and they did not know how to preserve books yet, only around 50 survived to this day.
