An Opinion on World War Z

Sudah menjadi salah satu impian saya dan seorang sahabat saya  untuk menghadapi zombie apocalypse atau kiamat dunia yang disebabkan oleh virus atau bakteri yang menjadi wabah dan membuat makhluk hidup menjadi mayat berjalan atau zombie.tetapi tentu saja dengan persenjataan dan ransum yang memadai.

Oleh karena itu saya hampir tidak pernah melewatkan film Hollywood yang bertemakan zombie apocalypse. Sebagai seorang penikmat bahkan bisa dikatakan penggemar berat film fiksi bertemakan zombie apocalypse saya melihat World War Z sebagai film yang sangat bagus, World War Z menurut saya merupakan salah satu film dengan tema zombie apocalypse terbaik. Karena dari segi alur cerita dansettingnya sangat terusun sedemikian rupa hingga menurut saya tidak ada yang missed dari film ini. Apa yang membuat saya berpikir demikian, tak lain adalah karena ide untuk membuat para zombie hanya memburu manusia – manusia yang sehat.

Terdapat hal yang ingin sampaikan mengenai film ini yaitu spesifikasi zombienya. Dalam film ini, zombienya memiliki kekuatan fisik yang menurut saya terbilang sangat amat atletis. Zombie – zombie tersebut dapat bergerak dengan kecepatan dan kekuatan selayaknya atlet American Football yang menurut saya hal ini merupakan hal yang tidak saya inginkan di kiamat dunia oleh zombie versi saya. Saya lebih memilih versi zombie yang terdapat di TV series The Walking Dead. Yaitu zombie yang lambat ketika lapar dan agak cepat ketika selesai makan, dan tentu saja zombie yang bisa mati apabila terdapat trauma dikepala atau atau ketika batang otaknya rusak seperti di film Resident Evil, sebab zombie di film World War Z tidak mempan dengan tembakan dikepala yang hanya memperlamabatnya saja. Kemudian hal yang menurut saya menarik dari film ini adalah para zombienya tidak didandani dengan tampilan yang seram dan sangat minim adegan yang menjijikkan seperti potongan tubuh atau semburan darah.

Terakhir saya ingin sampaikan apa yang menurut saya kurang dari film ini adalah belum adanya kabar mengenai sekuel film ini.

Distant Dwarf Planet Makemake Has Its Own Moon!It's all from "SPACE"

The dwarf planet Makemake has some company out in the cold, dark depths of the outer solar system. Astronomers using NASA's Hubble Space Telescope have discovered a moon orbiting Makemake, which is the second-brightest object in the distant Kuiper Belt beyond Neptune. (Pluto is the brightest of these bodies.) The newfound satellite — the first ever spotted around Makemake — is 1,300 times fainter than the dwarf planet and is thought to be about 100 miles (160 kilometers) in diameter, researchers said. The moon was spotted 13,000 miles (20,900 km) from the surface of Makemake, which itself is 870 miles (1,400 km) wide. "Makemake is in the class of rare Pluto-like objects, so finding a companion is important," Alex Parker of the Southwest Research Institute (SwRI) in Boulder, Colorado, who led the image analysis for the Hubble observations, said in a statement today (April 26). "The discovery of this moon has given us an opportunity to study Makemake in far greater detail than we ever would have been able to without the companion," Parker added. This photo by NASA’s Hubble Space Telescope reveals the first moon ever discovered around the dwarf planet Makemake. The 100-mile-wide (160 kilometers) satellite is barely visible just above Makemake, almost lost in the glare of the bright dwarf planet. Credit: NASA, ESA, and A. Parker and M. Buie (SwRI) For example, further observations of the moon — which has been provisionally named S/2015 (136472) 1, and nicknamed MK 2 — should allow astronomers to calculate the density of Makemake, which should  tell them if the dwarf planet and Pluto are made of similar stuff. "This new discovery opens a new chapter in comparative planetology in the outer solar system," said team leader Marc Buie, also of SwRI. Additional Hubble observations should also reveal the shape of MK 2's orbit around Makemake. If the orbit is tightly circular, the moon was probably created by a long-ago giant impact, just like the five satellites in the Pluto system were, researchers said. A looping, elliptical orbit, on the other hand, would suggest that MK 2 was once a free-flying Kuiper Belt object that Makemake captured.

Credit: Karl Tate, SPACE.com contributor The Hubble discovery images suggest that MK 2 is as dark as charcoal, which seems surprising given that Makemake is so bright. One possible explanation is that the moon's gravity is too weak to hold onto reflective ices, which sublimate off MK 2's surface into space, researchers said. Makemake orbits the sun at an average distance of 45.7 astronomical units (AU) and completes one lap around the star every 309 Earth years. (One AU is the Earth-sun distance — about 93 million miles, or 150 million km.) The dwarf planet is even farther away than Pluto, which lies 39.5 AU from the sun on average and orbits once every 248 Earth years. Makemake is one of five objects officially recognized as a dwarf planet by the International Astronomical Union (IAU). The others are the Kuiper Belt denizens Pluto, Eris and Haumea, and Ceres, which lies in the main asteroid belt between Mars and Jupiter. Ceres is the only one of these five that doesn't have at least one moon. The IAU defines a dwarf planet as an object that orbits the sun and is massive enough to have been forced into a spherical shape by its own gravity but has not "cleared its neighborhood" of other orbiting material. (Pluto falls short on this last count, according to IAU officials, which is why the former ninth planet was reclassified as a dwarf planet in 2006.) MK 2 was spotted in observations made by Hubble's Wide Field Camera 3 in April 2015, after several previous Makemake observation campaigns had failed to turn up any satellites. "Our preliminary estimates show that the moon's orbit seems to be edge-on, and that means that often when you look at the system you are going to miss the moon because it gets lost in the bright glare of Makemake," Parker said.

"Black Hole" Beyond Curiosity

The Ultimate Reference: NASA

What is Black Hole? A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars. How Big Are Black Holes? Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or "stuff," in an object. Another kind of black hole is called "stellar." Its mass can be up to 20 times more than the mass of the sun. There may be many, many stellar mass black holes in Earth's galaxy. Earth's galaxy is called the Milky Way. The largest black holes are called "supermassive." These black holes have masses that are more than 1 million suns together. Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy is called Sagittarius A. It has a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earths. How Do Black Holes Form? Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star falls in upon itself, or collapses. When this happens, it causes a supernova. A supernova is an exploding star that blasts part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in. If Black Holes Are "Black," How Do Scientists Know They Are There? A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting, a black hole. When a black hole and a star are close together, high-energy light is made. This kind of light can not be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light. Could a Black Hole Destroy Earth? Black holes do not go around in space eating stars, moons and planets. Earth will not fall into a black hole because no black hole is close enough to the solar system for Earth to do that. Even if a black hole the same mass as the sun were to take the place of the sun, Earth still would not fall in. The black hole would have the same gravity as the sun. Earth and the other planets would orbit the black hole as they orbit the sun now. The sun will never turn into a black hole. The sun is not a big enough star to make a black hole. How Is NASA Studying Black Holes? NASA is using satellites and telescopes that are traveling in space to learn more about black holes. These spacecraft help scientists answer questions about the universe.
