Is Time Travel Possible? Stephen Hawking's Changing Perspective
- Renowned physicist Stephen Hawking initially doubted the possibility of time travel due to the absence of future tourists. He challenged the physics community to create a law to make time travel impossible. However, no such law has been found, and time travel appears to be consistent with known physics.
- Despite his initial skepticism, Hawking has recently changed his perspective. He now believes that while time travel may be possible, it is not practical.
- Hawking's evolving stance on time travel has attracted attention and sparked discussions about the feasibility and implications of traversing through time.

In 1990, world-famous physicist Stephen Hawking read papers of his colleagues proposing their version of a time machine, but he was immediately, skeptical. His intuition told him that time travel was not possible because there are no tourists from the future. Hawking also raised a challenge to the world of physics. There ought to be a law, he proclaimed, making time travel impossible. The embarrassing thing, however, was that no matter how hard physicists tried, they could not find a law to prevent time travel. Apparently, time travel seems to be consistent with the known laws of physics. Unable to find any physical law that makes time travel impossible, Hawking has recently changed his mind. He made headlines in the British papers when he said, “Time travel may be possible, but it is not practical.”

以下のとおり、訳文をお答えします。（面白い内容でした。） （訳文） 《1990年、世界的に有名な物理学者スティーブン・ホーキングが、タイムマシンに関する見解を提示する同僚の論文を読んだが、彼は即座に疑いを抱いた。彼は直感によって、未来からの旅行客がいないので、タイムトラベルは不可能であると感じたのである。ホーキングはまた物理学の世界に挑戦を投げかけた。タイムトラベルを不可能とする（不可能であることを示す）法則があるはずだと宣言したのである。 しかし、困ったことに、物理学者らがいかに頑張って努力しても、彼らはタイムトラベルを妨げるような法則を見つけることはできなかった。明らかに、タイムトラベルは物理学の既知の法則と一致しているようなのだ。タイムトラベルを不可能にするような物理的な法則を見つけることができなかったため、ホーキングは最近彼の考えを変えた。彼は「タイムトラベルは、可能かもしれないが現実的ではない」と語って、イギリスの新聞の見出しを飾った。》

お遊び程度に訳してみたものですが ・・・ * * * 1990年に、高名な物理学者のスティーブン・ホーキングは物理学者たちが自分たちの考えたタイムマシンのアイデアを公開したものを読んで、一読して否定的な考えを抱いた。彼の考えるところでは、時間旅行というものは不可能であり、だから未来から帰還したという者などいない。そこでホーキングは、物理学会に提案をした。タイム・トラベルは不可能であるという根拠を示してくれと求めたのだ。 しかし、困ったことに、物理学者たちがどう考えても、タイム・トラベルが不可能であるとする理論を示すことができなかった。何とか回答を出そうと試みたものの、タイム・トラベルが物理法則に反しているようには見えないのだ。タイム・トラベルが不可能だという物理法則を見いだせないということを受けて、ホーキングは最近彼の考えを変えた。 ホーキングは 「時間旅行が不可能だとは言わないが、実際に行うことは出来ない」 と述べて、英国の新聞に大きく取り上げられた。

お願いします (5) Although he was still an inexperienced teenager, Octavius was suddenly a public figure. He would soon be plunged into the cutthroat world of Roman politics. His mother and stepfather saw how dangerous this could be. They tried to persuade him to stay away from Rome. But Octavius was determined, and he set out to claim his inheritance. As a first step, he took his adoptive father's name and combined it with his own birth name. He became Gaius Julius Caesar Octavianus. (6) Rome, meanwhile, was in the hands of Caesar's deputy, Mark Antony. He had seen the assassination and moved quickly to grab power. Octavian was not yet in Rome, so Antony delivered Caesar's funeral oration. His speech helped to persuade people that the dictator's assassins were the enemies of Rome. With lightning speed, Antony took over Caesar's money, property, and all of his official papers. (7) This was not what Caesar had wanted. In his will, he promised a generous gift of money to every Roman citizen. But Antony refused to honor the murdered hero's wish. (8) When Octavian reached Rome, he honored his great-uncle by giving his own money to the citizens. With the help of Cicero's speeches and with Caesar's veterans marching behind him, Octavian earned the support of the Senate. Not only was he elected to the Senate, he also became a consul─even though, according to Roman law, he was too young to hold these offices. Octavian bragged about it when he later wrote his memoirs.

When the Lord Townshend was Minister of State，a brother of his was content to be a City merchant ; and the time that the earl of Oxford governed Great Britain ，his younger brother was no more than a factor in Alleppo, where he chose to live, and where he died. This custom, which begins, however, to be laid aside, appear monstrous to Germans, vainly puffed up with their extraction. These think it morally impossible that the son of an English peer should be no more than a rich and powerful citizen, for all are princes in Germany. 英語の得意な方、日本語訳よろしくお願いします。

お願いします。 Chandragupta's most important weapon was not a war elephant,or even an army.It was his adviser,a clever and ambitious man named Kautilya.As a young man,Kautilya was an adviser to a king.He tried to convince the king to rule his people with knowledge and wisdom instead of ay force.Kautilya claimed that“a king who observes his duty of protecting his people justly and according to law will go to heaven,whereas one who does not protect them or inflicts unjust punishment will not.”The king refused and had Kautilya thrown out of his kingdom.From the gate,the king called to him,asking what good his knowledge was now. Kautilya swore he wouldn't cut his hair until he proved that knowledge was stronger than physical force.He wrote a book that explained his ideas called the Arthashastra,which means“The Book of Wealth and Power.”Kautilya also found a young prince who was willing to take his advice.The prince's name was Chandragupta Maurya. Chandragupta was an excellent student.Not only did he quickly defeat Kautilya's first boss,the king who had thought knowledge was useless,but he founded the Mauryan Dynasty,India's first centralized government.With kautilya's help,Chandragupta made many improvements to his empire,making it attractive to local rulers and their people.

お願いします (5) Many of Cicero's speeches and essays have also survived. They tell us what he thought about friendship, education, law, patriotism, and loyalty―to name a few of his topics. In an essay on duty, he described what a gentleman should and should not do. According to Cicero, it was just fine for a gentleman to own a farm, but he mustn't do the actual digging, planting, or plowing himself. In fact, a true gentleman would never work with his hands.(6) Cicero was a snob. He looked down on workers―even shopkeepers. He said that“they couldn't make a profit unless they lied a lot. And nothing is more shameful than lying.” He disdained fishermen, butchers, cooks, poultry sellers, perfume makers, and dancers because their work appealed to the senses of taste, sight, and smell. What would he say about hairdressers, movie stars, and rock stars if he were alive today? (7) Cicero was born in 106 BCE in the small town of Arpinum, not far from Rome. He came from a wealthy family that was well known in the region. But because none of his ancestors had ever served in the Roman Senate, Cicero was considered a“new man”―an outsider, not a genuine aristocrat. (8) As a teenager, Cicero traveled and studied in Greece, North Africa and Asia. While in Athens, he began his training as an orator―a skilled public speaker―convinced that this would be important in his political career. He was right. He understood that an orator needs a good memory and a huge store of information. But he said that it wasn't enough just to spout off a string of facts. An orator should use an actor's skills to put across his ideas. The words of a speech,“must be reinforced by bodily movement, gesture, facial expression, and by changes in the voice itself.”

お願いします (13) By 50 BCE, the Triumvirate had ended. Crassus had been killed in battle, and Pompey had become very jealous of Caesar's military success and his great popularity. Pompey had married Caesar's daughter, Julia, but when she died in childbirth, the bond between the two men was broken. Before Caesar returned from Gaul, Pompey sided wit the Senate to declare his former father-in-law an enemy of the State. The Senate demanded that Caesar give up his army and return to Rome. Knowing that he would be arrested if he obeyed, he refused. But now his life and career were at stake. Did he dare go back to Italy at all? (14) In January of 49 BCE, Caesar's forces were camped just north of the Rubicon, the river that marked the boundary between Gaul and Ital. As soon as Caesar heard the Senate's ruling, he slipped away from the camp with a few trusted men. It was night, and everyone else was feasting. No one noticed that he was missing. When he reached the banks of the Rubicon, he paused, thinking about his next step. After a moment, he declared, “The die is cast” and crossed the river. This was his way of saying that his mind was made up and wouldn't be changed. Now he was ready to meet his former ally, the great general Pompey, in battle. (15) Caesar was never one to stand around, waiting for someone else to do something. Decisive as always, he began his march right away. He set out in the dead of winter with a single legion of soldiers. He knew that by marching on Rome he would start a civil war. What he didn't know─and couldn't have known─was that this war would last for nearly two decades and destroy the Republic.

お願いします。 Pepi II wrote that he knew Harkhuf spent day and night with the caravan "doing that which thy lord desires, praises and commands." Not bad to have everyone running around trying to please you when you are barely nine. "Thy lord" has a nice ring to it, too. Despite all his power, Pepi II was still a young boy after all, and it was impossible for him to keep the excitement out of his letter. He had learned that Harkhuf was bringing home someone from the fabulous race of short people called pygmies. The talents of this particular dancing pygmy were so amazing that he was said to perform "the dance of the gods." Imagine waiting for someone that entertaining to arrive. Pepi II was having a little trouble waiting. "Come north to the Palace at once! Drop everything―hurry and bring that pygmy you have brought, alive, happy and well, for the divine dances, to gladden the heart, to delight the heart of the king who lives for ever!" (There's another kingly bonus―living forever.) Pepi II wanted to be sure the dancing pygmy arrived unharmed. He ordered: get trusty men to stand around him on the gangplank―don't let him fall in the water! When he goes to bed at night,get trusty men to lie all round him in his hammock. Inspect him ten times a night! My majesty longs to see this pygmy more than all the treasure of Sinai and Punt!

As the Allied operations in the Middle East were secondary to the Western Front campaign, reinforcements requested by General Sir Archibald Murray, commander of the Egyptian Expeditionary Force (EEF), were denied. Further, on 11 January 1917, the War Cabinet informed Murray that large scale operations in Palestine were to be deferred until September, and he was informed by Field Marshal William Robertson, the Chief of the Imperial General Staff , that he should be ready to send possibly two infantry divisions to France. One week later, Murray received a request for the first infantry division and dispatched the 42nd (East Lancashire) Division. He was assured that none of his mounted units would be transferred from the EEF, and was told "that there was no intention of curtailing such activities as he considered justified by his resources." Murray repeated his estimate that five infantry divisions, in addition to the mounted units, were needed for offensive operations.

お願いします (9) Knowing that he had very little support among the senators, Tiberius bypassed the Senate and took his proposal directly to the Assembly of the Plebs. He needed votes for his plan to become law, so he arranged for peasants to be brought in from the countryside to increase the number of votes in his favor. When another tribune, Octavius, tried to use his veto to stop the vote, Tiberius called for the Assembly to throw him out. According to Plutarch, one of Tiberius's servants dragged Octavius away. Luckily for Octavius, his rich pals rescued him from the angry mob. (10) With Octavius out of the way, the Assembly voted Tiberius's proposal into law. The senators tried desperately to block the actual transfer of land. They knew that it would involve a mass of paperwork, which is always expensive. All of the new farmers would need animals and tools. The total cost would be enormous. So the Senate refused to cover expense. That way, the hated law would be harmless─like a tiger without teeth. But Tiberius outsmarted them. He arranged to pay for the land transfers using money from a foreign kingdom. (11) Opinion in Rome was split. The way Tiberius had fought for his land reform, as much as thelaw itself, infuriated the senators. Tiberius had ignored the fact that the Senate was supposed to control Rome's finances. No wonder the nobleman hated him! But he became the common people's hero. This really worried the senators. They didn't want anyone to become too popular, especially with the Plebs. When Tiberius began to walk through Rome accompanied by bodyguards, the senators feared the worst. They thought he planned to take over the government by force and rule on his own, tossing aside written law and crippling the Senate's power.

お願いします (17) Augustus Caesar, now the emperor of Rome, worked to reorganize the government and military. His greatest accomplishment was the creation of a system of government that lasted in Rome for five centuries: the Roman Empire. (18) Augustus created Rome's first police and fire brigade. He created a network of roads that connected the major cities of the empire, linking them all to Rome. He changed the way finance were handled and issued new gold and silver coins. He gave free food to the poor. He built the Forum of Augustus and decorated it with statues of his ancestors. He beautified the city and boasted of this accomplishment: “I found a city made of brick and left it a city of marble.” Augustus also sponsored artists and poets like Horace and Virgil, whose works glorified Rome─and, of course, himself. (19) Throughout his reign, Augustus never forgot that his great-uncle had been killed by jealous enemies who feared his power and popularity. Augustus pretended that his powers were all voluntarily given. He allowed freedom of speech and encouraged people to give him advice. But he was clever. He knew how to use power without seeming to seek or even treasure it. During his rule, magistrates were still elected to govern Rome. By sharing power with the magistrates, Augustus kept people from worrying that he was governing Rome alone. In fact, the soldiers were loyal to him and him alone─he paid their salaries and his treasury would pay their pensions. (20) The emperor's authority was so great that everyone left all the major decisions to him. But he was also very careful. Augustus kept a force of 4,500 soldiers to defend him. These soldiers, later called the Praetorian Guard, protected all of Italy. But some of them were always on hand to protect the emperor. To be on the safe side, the guards allowed only one senate at a time to approach the emperor, and they searched each man before he came close.
