Uses Travertine is often used in counter tops, flooring, to resurface structures, and in cobble stoning. It is also used in a number of unique stone home furnishings. It is not as hard as quartzite, or as smooth as marble, although it can take a honed finish. Travertine is also available as Tufa, and as onyx, a semi translucent stone.

Travertine is mined heavily in Italy, U.S. and turkey. Historically it was used by Romans, Byzantines, and ottoman empires in their ancient architecture. Today it is widely used both indoor and outdoor and is one of most versatile components available on market. It is easy to maintain and clean, it is durable, reliable, and it doesn’t show dirt very much.

When you watch a star, you are actually only seeing light it emitted years ago. At present, star may be somewhere else in night sky. (Stars do move in space). It might have deflected a little to east or north or north-northeast. The star is still emitting light though. This light will however be seen in following decades or even centuries; or simply next year.

When you watch stars at night, you are actually looking in past. So who or what is time travelling? The star? You? Or light? The further something is from you, further in past you are penetrating into.

Maybe then, someday, newest technologies will be able to observe these seconds after Big Bang-if it ever occurred in first place.
