Vacuum

Vacuum is space void of matter. The word stems from the Latin adjective vacuus for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a perfect vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is lower than atmospheric pressure. The Latin term in vacuo is used to describe an object as being in what would otherwise be a vacuum.

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 (10−12) 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.

    Icaros

    by: Vacuum

    Sailing on a deep blue sea
    Where dolphins roam the waters free
    What's the law of nature:
    Can we fly like dolphins dive
    Standing on a mountain high
    I keep the faith to touch the sky
    These are dreams of heroes
    These are dreams to feel alive
    Eagles on solid air
    Put their trust in the atmosphere
    Riding on heavens high
    This is the way, this is the day
    Man has learned to fly
    Like the albatross covers the horizon
    Icaros, spread your wings and fly
    Like the albatross covers the horizon
    Icaros, spread your wings and fly
    Sitting in a rocket ship
    An exodus on a magic trip
    What's the law of nature:
    Can we open up the skies?
    Through the holes of time and space
    A future for the human race
    These are dreams of heroes
    These are dreams to feel alive
    Eagles on solid air
    Put their trust in the atmosphere
    Riding on heavens high
    This is the way, this is the day
    Man has learned to fly
    Like the albatross covers the horizon
    Icaros, spread your wings and fly
    Like the albatross covers the horizon
    Icaros, spread your wings and fly
    Eagles on solid air
    Put their trust in the atmosphere
    Riding on heavens high
    This is the way, this is the day
    Man has learned to fly
    (Like the albatross covers the horizon
    Icaros, spread your wings and fly)
    (Like the albatross) Like the albatross
    (covers the horizon) Icaros
    Spread your wings and
    Like the albatross covers the horizon
    Icaros, spread your wings and fly
    Like the albatross covers the horizon
