What happens to a shockwave in space?
Shock waves result when the matter through which the wave is passing is compressed and the molecules collide and vibrate. When the velocity of the disturbance is extreme, such as in the case of a meteor, electrons are knocked loose and the molecules are ionized. In space, explosions are constantly occurring.
How fast is a shockwave in space?
Scientists have captured the blast from a supernova 10,000 light-years away in a cosmic speed trap, clocking the shockwave from the dead star’s explosive end at speeds of nearly 8 miles per second.
How long would it take a shockwave to travel around the world?
Amazingly, for as many as 5 days after the explosion, weather stations in 50 cities around the globe observed this unprecedented spike in pressure re-occuring like clockwork, approximately every 34 hours. That is roughly how long it takes sound to travel around the entire planet.
Can you feel an explosion in space?
In space no one can hear you explode… Many astronomical objects such as novae, supernovae and black hole mergers are known to catastrophically ‘explode’. This means that they energetically destroy themselves or fundamentally change, releasing matter and energy into the Universe.
What happens if you detonate a nuke in space?
Finally, regarding the long-term effects of a nuclear weapon detonating in space, that radioactive material falling into the atmosphere isn’t going anywhere. In fact, it dissipates and spreads around the entire planet.
What would an explosion in space look like?
An explosion in space would realistically look like a brief spherical burst of light moving outwards, as well as a discharge of energy and material from the exploding object (energy and light can both travel in a vacuum).
How do you survive a shockwave?
Lie face down to protect exposed skin from the heat and flying debris. Avoid touching your eyes, nose, and mouth, if possible. If you are in a vehicle, stop safely, and duck down within the vehicle. After the shock wave passes, get inside the nearest, best shelter location for protection from potential fallout.
What happens when two shock waves meet?
When the intersection angle between two shock waves exceeds a critical value, the system reconfigures its geometry to create a normal shock known as a Mach stem where the shocks meet.
Are shock waves faster than sound?
In particular, shock waves travel faster than sound, and their speed increases as the amplitude is raised; but the intensity of a shock wave also decreases faster than does that of a sound wave, because some of the energy of the shock wave is expended to heat the medium in which it travels.
Can a scream be heard in space?
Sound is a mecanical wave, which means that it needs substance to travel through, such as air or water. In space, there is no air, so sound has nothing to travel through. If someone were to scream in space, the sound wouldn’t even leave their mouths.
Can you talk in space?
When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. In fact, the middle of space is very quiet. Sound travels in waves, and it moves at different speeds through air or water or other materials.
