Today’s science fiction movies‚ such as Interstellar‚ are based on new discoveries and research that older movies‚ such as 2001: A Space Odyssey‚ did not have. However‚ both movies stayed true to science‚ etc My goal in this paper is to discuss the accuracy of the physics and astronomy in Interstellar‚ and compare it to 2001: A Space

that all living things have an effect on the earths environment‚ including the atmosphere‚ the temperature and the location of the earth to the sun are very important factors to the planet. Earth as a fragile plant? From all the planets that we know about in the solar system as far as we know earth is the only planet with life on it. Which means that the earth is able to give us the materials and the nutrients we need to survive‚ such as water‚ and oxygen. For the earth to provide us with what

New life on other planets could mean so much for the future of humans. The only way to keep finding out new information about our solar system and beyond is to spend money to research it. The only way to prove that there is life on other planets is to conduct research. We have to make sure that we keep

few other elements and rocks. Around five billion years this cloud of materials began to spin and contract together into a disk shape under their own gravitational forces. The particles started combined together‚ protoplanets‚ to eventually form planets. A great mass of the material eventually began to form together‚ protosun‚ and make up the sun.

saw in the sky. They weren’t able to explain them and worshiped the sky bringing the power and the order of the sky down to Earth for part of their culture. Modern stargazers have the advantage of knowing what causes the motions of the Sun‚ Moon‚ planets‚ and stars. But that only increases their admiration for the ancients’ ability to track these celestial cycles. When studying the sky for any length of time‚ like ancient astronomers did‚ we find very obviously that there is a series of cycles‚ and

there‚ in fact‚ a manned mission to Mars would be useful to explore Mars and get information about the red planet. We should go to Mars because according to Gangle‚ “If Mars is dead now‚ but was once alive‚ understanding how Mars died may give us a crucial understanding of how close we are coming to killing the Earth” (qtd. in Joulwan‚ par.4). The mission helps us know more about our planet. Also‚ a manned mission to Mars can explore Mars for resources‚ for example‚ energy‚ minerals and much more

Monocerotis lies at a distance of 20‚000 light years from the sun and was once 60‚000 times brighter than the sun. Monocerotis is classified as a red colored variable star whose brightness changes either regularly or irregularly. V838 Monocerotis was first discovered as a brightening star by Nicholas J. Brown in Australia while he photographed an area of the sky as a part of a nova patrol (Cowen). As Brown looked at the images he had taken of the same area in the night sky for days‚ he noticed a
