Dark Matter Essay

The differences between rods and cones are useful but because both having different dim and light conditions. The fovea consists of densely-packed cone cells. The fovea part gives humans a clear central vision, allowing reading, bird watching, or any other task which primarily needs staring at things. As they cannot see dim stars, or other celestial objects, its needs for high intensity light does cause problems for astronomers. By using central vision because the light from these is not enough to

Big Bang, which is the moment the universe was believed to be created. The event horizons of these black holes are quite small, the width of an atomic particle. They can only hold up to the amount of matter of Mt. Everest. The formation of these little black holes are from the compression of matter caused by the

I Introduction hook : Black holes: the universe’s mystery B. Summary of Information: a black hole is a pit of blackness that sucks everything in like stars,planets,and when that happens no light comes out of the black hole. C. Thesis: Black holes are a mystery in the universe Body Paragraph: How black holes are formed. Transition: first, State your point : Black holes are interesting because of the history of how they are

Sagittarius A, is located about 26 000 light-years from Earth and contains a supermassive black hole. The other galaxy involved in the future collision is the Andromeda galaxy, or M31. There are about 1 trillion stars and could possibly contain more dark matter than the Milky Way. Its name comes from the constellation of Andromeda, which originated from the mythological princes Andromeda. It is a spiral type galaxy with at least two spiral arms and a diameter of 260 000 light-years. The mass of Andromeda

THE GAVITATIONAL LENSING AND THE APPLLICATION OF THE GAVITATIONAL LENSING TAO ZHE YU AND ZHE LONG PENG University of Wu Han ABSTRACT This paper introduceds the princeple of the gravitational lensing and the appllication of strong gavitational lensing,the weak gravitational lensing and the microlens Subject heading:gravitation--gravitational lensing 1.INTRODUCTION According to the Einstein’s general relativity, lights will bend in the gravity theory. So the light from background objects such as stars

People been wondering for year if we live in Hologram. At first I thought they was crazy and stupid for believing this theory. I was being arrogant and close minded about the topic. We started talking and reading more about the hologram theory. It's understandable on how people that we are in a hologram. The article "Our world May Be a Gigantic Hologram" was the first article to educate me about the hologram theory. The second article was about the black hole and how representation of a universe

The material has a very small amount of kinetic energy and it has a large amount of potential energy. The particles aren't moving much at all. The substance appears to be solid. This is because the particles are close together and they barely have any kinetic energy. The substance appears to be solid. This is because the particles are close together and they barely have any kinetic energy. The particles started to move around more and gained kinetic energy. They were also staring to spread

phenomena -- known as relativistic jets -- by measuring how quickly they 'switch on' and start shining brightly once they are launched. How these jets form is still a puzzle. One theory suggests that they develop within the 'accretion disc' -- the matter sucked into the orbit of a growing black hole. Extreme gravity within the disc twists and stretches magnetic fields, squeezing hot, magnetised disc material called plasma until it erupts in

anomalies in Fig 6a (now Fig 5a) become deeper after LMI.  Caption: Evolution relative to LMI of the climatological background temperature in hurricane-strength TCs between ±35° of latitude. Additionally, we mentioned that we are not gathering temperature measurements poleward of 35° of latitude to limit the sampling of profiles poleward of the jets (jets are located around ±45° of latitude during the local summer when tropical cyclones form). • Fig 4: If possible, it would be really helpful
