6. Koenigsegg CCXR Trevita
The name Trevita is a Swedish acronym meaning “three whites” in English. Initially, it was planned to be launched as a three-piece limited edition but after facing incredible difficulty in production, the number of this car produced was limited to two. This limited-edition model costs $4.8 million.
"In space, no one can hear you scream"- This is a tagline from the 1979 movie Alien. This is 100 per cent true as there is no sound or echo in space. But why so?
Sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. Sound is carried by atoms and molecules. Astronomer Chris Impey says that in space, with no atoms or molecules to carry a sound wave, there is no sound.
Impey says that no sound also means no echo.
Though hypothetical, our voice on Mars would sound tinny and hollow, like the sound of a piccolo, Impey says. On Venus, our voice would be much deeper, like the sound of a booming bass.
