5 of the most fantastic and terrible ways to die
Physical scientist Paul Doherty and science fiction writer Cody Cassidy appeared in the forum thread on the popular online resource Reddit, where they talked about their two-year job in search of the worst ways to die. Experts answered questions from users who began to offer their versions of the most cruel deaths.
Two years ago, Paul Doherty and Cody Cassidy released a book under the optimistic title "And then you die", which collected the most sophisticated circumstances of death and from a scientific point of view answered questions like "What will happen if I swallow the whale" or "What will happen if you put your hand into the hadron collider. "
The experts examined a lot of deadly situations, and here are five of the most interesting, four of which, fortunately, do not threaten us in real life.
Is it possible to kill a person with a loud sound?
A sound louder than 185 dB is considered a deadly loudness threshold for a person. Too loud sound leads to air embolism - the penetration of bubbles into the artery and its blockage. As a result, the blood stops flowing to the heart and brain.
120 decibels is painful. 150 decibels is the loudness of a jet engine of an airplane, if you stand nearby. The sound of 154 decibels is used to test the strength of spacecraft. An explosion, as is well known, can produce a sound shock wave that breaks the human lungs. A biting sound of more than 190 decibels is something similar. So yes, the sound can be killed.
What will happen if you tie a cargo to a person and send it to the bottom of the Mariana Trench?
If you just slowly sink into the Mariana Trench with a load on your legs, you will simply be drowned. Therefore, it is much more interesting to find out what will happen if you exit the bathyscaphe, being at the bottom. Basically, the human body consists of water, so you will generally remain the same shape as on land. But there is a problem with air cavities in the body: in the nose, throat, chest. Of course, they will fail inside. And then you die. And the compressed body does not even emerge, but remains at the bottom.
Approximately the same will happen on the surface of Mars, where a person can survive for about 15 seconds before the air from the lungs is completely gone.
What happens if you drill a tunnel through the Earth and jump into it?
This is a classic school problem in physics. As you know, you reach the opposite end in 45 minutes. But this answer is very boring, because the most interesting thing will happen to you along the way.
In fact, you will burn to the atoms even before falling into the nucleus, because the center of the Earth is hotter than the surface of the Sun. In addition, the pressure and density of air doubles every 4.57 km of depth, so after a 10-fold doubling (at a depth of 45.7 km), the air will be as dense as water and will not let you go deeper.
What happens if you get close to a neutron star?
If you find yourself close to a neutron star, your body will either break in half from a strong and uneven attraction, or a strong magnetic field will destroy all bonds between atoms in the body, and it will turn into a piece of liquid plasma.
How to increase the chances of survival if you were in a falling elevator?
The experts explained that it is useless to jump in a falling elevator, but lying on your back is a good option. So the impact will be distributed evenly throughout the body. If you stand, you will already land, and your organs will continue to fly to the floor. All hope is that the walls of the elevator are relatively tight to the walls of the shaft and at the bottom there will be a slight air pressure plus a fallen cable will slightly absorb shock.
