The quality of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. Much higher-quality vacuums are possible. Ultra-high vacuum chambers, common in chemistry, physics, and engineering, operate below one trillionth (1012) of atmospheric pressure (100 nPa), and can reach around 100 particles/cm3. Outer space is an even higher-quality vacuum, with the equivalent of just a few hydrogen atoms per cubic meter on average. According to modern understanding, even if all matter could be removed from a volume, it would still not be "empty" due to vacuum fluctuations, dark energy, transiting gamma rays, cosmic rays, neutrinos, and other phenomena in quantum physics. In the electromagnetism in the 19th century, vacuum was thought to be filled with a medium called aether. In modern particle physics, the vacuum state is considered the ground state of matter.

If all matter is removed from a vacuum, would it be empty space?
Answer: it would still not be "empty"

Jose Manuel Gonzalez-Paramo, a Spanish member of the Executive Board since June 2004, was due to leave the board in early June 2012 and no replacement had been named as of late May 2012. The Spanish had nominated Barcelona-born Antonio Sainz de Vicuna, an ECB veteran who heads its legal department, as Gonzalez-Paramo's replacement as early as January 2012 but alternatives from Luxembourg, Finland, and Slovenia were put forward and no decision made by May. After a long political battle, Luxembourg's Yves Mersch, was appointed as Gonzalez-Paramo's replacement.

Who did the Spanish want to take Jose Manuel Gonzalez-Paramo's seat on the board?
Answer: Antonio Sainz de Vicuna

In the Early Middle Ages, from the end of the 4th century, the western extent of modern-day Switzerland was part of the territory of the Kings of the Burgundians. The Alemanni settled the Swiss plateau in the 5th century and the valleys of the Alps in the 8th century, forming Alemannia. Modern-day Switzerland was therefore then divided between the kingdoms of Alemannia and Burgundy. The entire region became part of the expanding Frankish Empire in the 6th century, following Clovis I's victory over the Alemanni at Tolbiac in 504 AD, and later Frankish domination of the Burgundians.

What Empire did the entire region of Modern-day Switzerland become part of in the 6th century?
Answer:
Frankish Empire
