Cosmology As we have learned, Edwin Hubble showed that the farther away a galaxy is, the faster away from the Milky Way it is moving. This gives the appearance that the Milky Way is at the center of the universe, and all galaxies are moving away from us, possibly due to some large explosion, The Big Bang. The Hubble's Law can be applied to any observer in any galaxy. No matter where you are, an expanding universe will give the same appearance. The expansion of the universe is not like the explosion

* Question 1 Needs Grading | | | What is the helium fusion reaction, and why does it require much higher temperatures than hydrogen fusion? | | | | | Selected Answer: | Helium fusion reaction is the transformation of 3 Helium nuclei into one carbon nucleus. It requires much higher temperatures than hydrogen fusion because it has a greater positive charge (two protons), which requires a strong force to deal with electromagnetic repulsion. | Correct Answer: | The helium fusion reaction

HUMAN HEALTH AND GLOBAL ENVIRONMENTAL CHANGE The Global Warming is not occurring evenly. The effect is high in the poles especially the Arctic. We know the Globe is warming from thermometers placed at various points in the Earth. This gives data from about 1830’s to current day. The oldest thermometer employed to find the atmospheric temperature was from Germany. But the disadvantage is we can go back only 200 years or so. To find the facet of climate before those periods, we use ICE. Ice

expand). Red shift is when objects are moving away from us, which means longer wave lengths of light "shifting" towards the red end of the spectrum. Cosmic background radiation is another piece to help support the Big Bang theory. Just after the Big Bang electromagnetic radiation was created. Now, the radiation is seen as microwave radiation. Edwin Hubble studied the movement of planets during the early 1900's. Hubble and his not as famous partner Milton Humason worked together to conclude that the universe

The blood or hemolymph, as in other arthropods, is carried in an open circulatory system.[3] The body organs, "heart" (dorsal aorta), muscles, etc. are surrounded in a reservoir of blood, and pulsing contractions of the tube-like dorsal aorta create a weak circulatory force. In fertilised queens the ovaries are activated when the queen lays her egg. It passes along the oviduct to the vagina. In the vagina there is a chamber called the spermatheca. This is where the queen stores sperm from her

There have been many theories concerning what the universe looks like, how it became this way, and where it is going. For many years the universe has confused many astronomers and scientist, it is difficult to have a good understand of something that is so far away. Especially, back then where there was a lack of tools to be able to view and see the universe like we do today. However, with the collaboration of many great scientists and astronomers we have established a more concrete understanding

neutron star is a rare star type that is made up completely of neutrons. This occurs because of the protons and electrons in the star that are crushed together by the intense gravity. If a star is any bigger than a neutron star, they will become black holes after the supernova. Supergiant stars are the largest type of stars in the universe that humanity knows of. These stars are so massive, they can be up to dozens and dozens of times the size of the sun. The supergiant stars do not live long. They
