meter Travel - Essay ExampleAnd having thought what to do, we can only do it now while the quantify for action is future we can only await it, and once it is ultimo it is too late.When it comes to time voyage, the erudition of difference somewhat diminishes, according to various scientists theories presented in various ways we conclude that most of them retard with the notion that in modulate to proceed back in time one has to travel high-velocity than the speed of light. Only in such condition one can travel in time. along with the speed of light, there argon other three factors that are considered for a person in order to travel. Those factors or four elements on which time travel is based are considered at the very snapper of science fiction, which areFoote has his own unique perception according to which traveling whether it be the future or the past is reasonable to justify and can be universally accepted by the judgment that a person is always involved in traveling al l the time, each minute and at every second and particularly in his sleep because as we sleep our consciousness takes a several hour-long leap into the future. It is no wonder that this scenario has a respectable, if dateable, past in the literature of science and fiction. But nothing, nothing remove dream and memory, stands in relation to travel to the past as sleep does to travel to the future. Travel to the past takes all customary notions of cause and effect, as Foote believes in the laws of thermodynamics. (Foote, 1991, p. 9) which suggests, heat is a form of energy that is in transaction. Let us examine this quotation what Foote has said. Heat is a form of energy and so is the man. A living energy in the form of meat and flesh. A man if moves in motion obviously generates and radiates energy and if a man travels alacritous than the speed of a light it is for sure that he would wake up in an environment which is quite old and ancient for him.Faster than light travelNo doub t Foote has related human capabilities with those of the speed of light. Here is the theory presented by Foote based upon FTL travel first it is true that the physicists of the tribe have devised a mathematical fiction called the tachyon, which, if it exists, must travel faster than light. Greatly simplified, the logic runs like this in the universe we observe, we postulate the existence of tardyons, particles which must travel more slowly than light, and luminons, which always travel at precisely the speed of light. The more energy one puts tramp a tardyon, the faster it travels and the heavier it gets but as one approaches the speed of light, vast increases in energy are required to accomplish minuscule increases in speed. Only an infinite amount of energy which is not accessible to us in this universe will suffice to bring a tardyon to the speed of light. (Foote, 1991, p. 9)thither is indeed an asymmetry in respect of past and future in the way in which we distinguish events when we are considering them as standing in causal relations to one another Macbeath explains this as it reflects an accusing asymmetry in nature and thinks that this asymmetry would reveal itself to us even if we were not agents but innocent observers. It is indeed true, that our concept of cause is bound up with our concept of intentional action if an
