Is supernova a dying star?
One type of supernova is caused by the “last hurrah” of a dying massive star.
This happens when a star at least five times the mass of our sun goes out with a fantastic bang.
Massive stars burn huge amounts of nuclear fuel at their cores, or centers.
This produces tons of energy, so the center gets very hot..
Can sound travel through space?
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.
How many decibels will kill a human?
Acoustic grenades can go roughly from 120 decibels to 190 decibels. German researcher Jurgen Altmann showed that a blast of 210 decibels or more affects the inner organs — the lungs — and could cause internal injury that could lead to death. A blast will impact the body, and would do so very violently.
What does space smell like?
sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’. Some astronauts have likened the smells of space to walnuts.
Why is space silent?
In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. ‘Outer space’ begins about 100 km above the Earth, where the shell of air around our planet disappears.
Is 70 dB safe?
Decibel Level Sounds at or below 70 dBA are generally considered safe. Any sound at or above 85 dBA is more likely to damage your hearing over time. Researchers have found that people who are exposed over long periods of time to noise levels at 85 dBA or higher are at a much greater risk for hearing loss.
Is there noise on the moon?
And the atmosphere of Saturn’s moon Titan resembles the static noise coming off a TV, with a rhythmic sound going on and off in the background. Space is a vacuum — so it generally doesn’t carry sound waves like air does here on Earth (though some sounds do exist in outer space, we just can’t hear them).
Does a supernova make noise?
They’re so far apart though, the particles don’t immediately collide with each other allowing a sound wave to pass through a grouping of them. So, even if you did watch the Death Star explode, you couldn’t hear it. … There’s no sound in space, so you can’t hear what a supernova sounds like.
How loud is 1100 decibels?
1100 decibels is preposterous. 20 db is ten times as loud as 10 db. To the Human ear, it sounds about twice as loud.
What is the loudest sound in the universe?
The sound made by the Krakatoa volcanic eruption in 1883 was so loud it ruptured eardrums of people 40 miles away, travelled around the world four times, and was clearly heard 5,000 kilometers away. This is hailed as the loudest noise ever – and reported in.
How loud is the sun?
around 100 decibelsDeForest pegs the sun’s din on Earth at around 100 decibels, a bit quieter than the speakers at a rock concert.
Where is the quietest place on Earth?
Redmond, Washington1. Building 87, Washington, US. Described as “where sound goes to die”, this Microsoft research lab in the city of Redmond, Washington, is officially the quietest place on Earth, according to Guinness World Records.
