Black Holes, Worm Holes and Parallel Universes
Black holes are high-density objects whose gravitational attraction is so strong that they can attract light particles whenever they come near them. Such objects cannot break away once in contact because of the strong force. They are classified into three categories depending on their mode of formation and their size relative to that of the sun and earth. Such include Stellar black holes, Supermassive black holes and Intermediate black holes. The existence of these holes could be explained if it’s possible to reduce the earth to a marble where gravity surrounding the earth becomes greater with decrease in size.
Wormholes are imaginary passages that are believed to bridge the time-space across universes. These passages tend to collapse when objects pass through them. They do so along the long neck that connects their two openings. The existence of worm holes has not been proven as yet despite predictions by scientists about their existence.
Parallel universe are universes that are believed to exist and resemble the known universe. It is believed that there could be a possibility that our planet branched from these other parallel universes or they could have branched from ours as well. This proposition was further enhanced with the discovery of the quantum physicists in the University of California.
My opinion about these theories and proposition is that the development of science is rather based on fantasies and development of scientific facts becomes difficult because of the fictional ideas developed by many scientists. Though it may take time, some of these theories such as the existence of parallel universes may be proven. This is because of the relationship of the proposition with practical science such as Quantum physics. However, while it may be possible to escape from the earth’s surface, reduction of the earth to a marble size is just an impractical idea which betrays the validity of existence of Black holes. The belief of the existence of black holes, worm holes and parallel universe is therefore a line of thought in science that’s suggests how much possibilities there are in the universe and the current understanding is perhaps a fraction of the unlimited possibilities.
Anthropogenic forces on the global system have risen to a level whereby unexpected international environmental modification cannot be left out anymore. A fresh advance to global sustainability has been recommended whereby planetary boundaries are classified within which it is anticipated that humanity may function in safety. Transgression of a single or many planetary boundaries might be harmful or tragic because of the danger of crossing thresholds that can elicit nonlinear, rapid environmental alteration in the continental to planetary-level schemes. Nine planetary boundaries have been discovered, and with respect to scientific comprehension, quantification has been suggested for seven of them. They include climate change, stratospheric ozone, ocean acidification, land system change, and biogeochemical nitrogen among others. No boundary point has been established for atmospheric aerosol loading as well as chemical pollution.
It has been established that humankind has already overstepped three planetary boundaries, which encompass the level of biodiversity loss, modification to the international nitrogen cycle, and climate change. Planetary boundaries have been proved to be interdependent as the transgression of one might change the situation of another or end up transgressing others. The social control of the transgression of planetary boundaries will be a task of the social-ecological pliability of the influenced societies. The recommended boundaries are uneven, just approximations, and enclosed by doubts and knowledge gaps. Bridging the gaps demand major improvements in the system and resilience discipline. The suggested perception of planetary boundaries sets the basis for switching one’s approach to management, as well as control past fundamentally sectoral assessment of confines of development geared toward the reduction of negative externalities and evaluation of secure space for human advancement. Planetary boundaries identify the limits of playing fields for the human race in terms of guaranteed evasion of main human-related environmental change on an international level.
Astronomers focus on distant and small objects using telescopes. Telescopes are machines that collect light that helps to focus on an image. A small astronomical telescope is made up of the objective lens, the eyepiece, and the focal point. The objective lens refracts or bends parallel light rays causing them to converge at a particular point to focus on a specified object. The central point is the meet point whereby the rays are refracted. The eyepiece is the part that positions the image in a way that is easy for the viewer to have a good field of view. It allows the eye to view the image comfortably for an extended period.
The distance between stars is measured by a filar micrometer. The micrometer has two fine parallel wires that are movable by the observer. While measuring the distance between the stars, the observer places one wire over one star of interest and moves the other wire to the second star. The distance between the two wires is the angular distance between the two stars. A HR diagram is used by astronomers to classify stars. The diagram classifies the stars according to their color, temperature, luminosity, and evolutionary stage. The figure below illustrates the classification of stars by the HR diagram.

Light curves are used to determine the type of binary star system that is observed. The brightness of the curve that describes an eclipsing binary orbit is measured from 0.0 to 1.0. The stars appear based on the amount of brightness that is available. Therefore, at some point of a light curve, two stars in close orbit around each other. The difference in the intensity of the light curve determines the binary starts that are caused by one star passing in front of the other.
