Because its density is so high, neutrons spin in the same way that electrons do so must obey the Pauli Exclusion Principle. 6. A pulsar does not pulse, it emits beams of radiation that sweep around the sky as the neutron star rotates, and astronomers detect pulses when they sweep over the Earth. 11. Sometimes in binary systems, mass flows into a hot accretion disk around the neutron star and causes the emission of x rays.
Then Kaku states that force fields can do more than deflecting laser beams because it can levitate objects by the use of magnetic force fields. To support that, he explains that when we place two magnets opposite to each other, the two magnets will repel each other. However he wrote that making force fields and to levitate heavy objects is nearly impossible since we lack advanced technology. For my response, Kaku doesn’t completely explain everything. Suppose that you have a structure on a planet or a spaceship in the middle of nowhere, and suppose you don't want the force field on all the time either because there are times when protection isn't needed.
We cannot make an infinite cylinder and such things as wormholes and cosmic strings probably do not exist (2011).” Barclay also stated, “Even if they did, they would still be uncontrollable methods of time travel. How can you tell a cosmic string of energy where to take you (2011)?” Certainly we cannot travel through time forward or backwards, in a car or phone booth, a mass of swirling structure or even fall into a pond. We can time travel in a different way,
McCloskey states that one of the major problems is believing in an uncaused first cause. He states that the mere existence of the universe does not constitute for believing in a being (God). While McCloskey has this view, we learn in the readings of Evans and Manis (2009), that the term contingency of the universe is often used to refute the question of what about the universe support the claim that God exists (pg. 69). This merely states that if we look around at the universe we will see things that may or may not have existed if there was not a God or other necessary being.
Describe two ways in which gravity has a part in the life-cycle of a star- Gravity pulls the dust and gas in the nubula together, and compresses them so much that the inside becomes hot enough for fusion reactions to start. Gravity also pulls the remains of a red giant together after fusion reactions have stops. This forms a white dwarf. Theories about the universe- 1. What does red shift tell s about distant galaxies?
A scientific control is the group not exposed to the conditions of the experiment, the control is designed to minimize the effects of variables other than the single independent variable. Site 2 does not have kudzu. BONUS QUESTION: (Worth 2 points) What is the difference between astronomy and astrology? Which of them is true science versus pseudoscience? 1.
Anaximander, who was a student of Thales, argued that the four elements, water, air, earth, and fire can change into one another and therefore none of those elements could be the principle element, the Arche. Anaximander’s Arche was something he called Aperion. Aperion, he claimed, was an infinite, boundless substance that all of the elements were derived from and that things can into being by necessity. Anaximander was also very interested in astronomy. From his observations, Anaximander concluded that the sun was nothing more than a disk with hot gas escaping out of it, and that the stars were holes in the sky where light shined through.
For example, it appears that electrons can pass out of existence at one point and come back into existence elsewhere. One can neither trace their intermediate existence nor determine what causes them to come into existence at one point rather than another. Neither can one precisely determine or predict where they will reappear; their subsequent location is only statistically probable given what we know about their antecedent states. Hence, “quantum-mechanical considerations show that the causal proposition is limited in its application, if applicable at all, and consequently that a probabilistic argument for a cause of the Big Bang cannot go through” (Smith, in Craig and Smith, 1993, 121–23,
This is where the theories of the Big Bang and Evolution fail. They attempt to arrive at the conclusion that this universe is eternal, but their own scientific theories about the age of the structure in which we live force even the most dedicated Atheist to admit that it was indeed created at some point in time. Therefore, if the universe was created, something greater than the universe was the engineer behind its initial
The answer to ”why does the Earth rotate” leads down the dark path of physics. A murky place where few have willingly gone. The answer lies within the law of conservation of angular momentum. Angular momentum is the rotational counterpart of momentum. The angular momentum of an object is defined relative to a fixed point.
