Question: Time travel is the concept of moving backwards or forwards to different points in time, in a manner analogous to moving through space, and different from the normal "flow" of time to an earthbound observer. In this view, all points in time (including future times) "persist" in some way. Time travel has been a plot device in fiction since the 19th century. Traveling backwards in time has never been verified, presents many theoretic problems, and may be an impossibility. Any technological device, whether fictional or hypothetical, that is used to achieve time travel is known as a time machine.
Is there an answer to this question: How long has time travel been a topic in theory?

Answer: unanswerable


Question: Conflict with Arius and Arianism as well as successive Roman emperors shaped Athanasius's career. In 325, at the age of 27, Athanasius began his leading role against the Arians as his bishop's assistant during the First Council of Nicaea. Roman emperor Constantine the Great had convened the council in May–August 325 to address the Arian position that the Son of God, Jesus of Nazareth, is of a distinct substance from the Father. Three years after that council, Athanasius succeeded his mentor as archbishop of Alexandria. In addition to the conflict with the Arians (including powerful and influential Arian churchmen led by Eusebius of Nicomedia), he struggled against the Emperors Constantine, Constantius II, Julian the Apostate and Valens. He was known as "Athanasius Contra Mundum" (Latin for Athanasius Against the World).
Is there an answer to this question:  Athanasius was never known as what?

Question: When the news arrived in England it caused an outcry. In response, a combined bounty of £1,000 was offered for Every's capture by the Privy Council and East India Company, leading to the first worldwide manhunt in recorded history. The plunder of Aurangzeb's treasure ship had serious consequences for the English East India Company. The furious Mughal Emperor Aurangzeb ordered Sidi Yaqub and Nawab Daud Khan to attack and close four of the company's factories in India and imprison their officers, who were almost lynched by a mob of angry Mughals, blaming them for their countryman's depredations, and threatened to put an end to all English trading in India. To appease Emperor Aurangzeb and particularly his Grand Vizier Asad Khan, Parliament exempted Every from all of the Acts of Grace (pardons) and amnesties it would subsequently issue to other pirates.
Is there an answer to this question: What was the name of the council that offered all of the bounty for Captain Every?

Answer: unanswerable


Question: Asthma is the result of chronic inflammation of the conducting zone of the airways (most especially the bronchi and bronchioles), which subsequently results in increased contractability of the surrounding smooth muscles. This among other factors leads to bouts of narrowing of the airway and the classic symptoms of wheezing. The narrowing is typically reversible with or without treatment. Occasionally the airways themselves change. Typical changes in the airways include an increase in eosinophils and thickening of the lamina reticularis. Chronically the airways' smooth muscle may increase in size along with an increase in the numbers of mucous glands. Other cell types involved include: T lymphocytes, macrophages, and neutrophils. There may also be involvement of other components of the immune system including: cytokines, chemokines, histamine, and leukotrienes among others.
Is there an answer to this question: What chronic changes happen to the macrophages?
