Dawn is one of nature's most magnificent sights. On calm mornings, the first rays of sunlight slowly spread across the landscape as the Earth gradually emerges from darkness.
This quiet moment has inspired many composers and artists who have tried to turn this soundless experience into music. But if people could actually hear the Sun, the noise would be deafening.
The Sun is essentially a giant nuclear fusion reactor. Inside it, hydrogen is converted into helium, and during this process, an incredible amount of energy is released in the form of heat and vibrations - and therefore sound.
Sound is essentially a vibration that travels through a medium, such as air or water. But between the Earth and the Sun lies a vast vacuum of about 93 million miles. It is this void that prevents any sound from reaching us.
If the space between the Earth and the Sun were filled with air, the noise of nuclear reactions would create a continuous sound of more than 100 decibels – about the same as the noise of a chainsaw or the speakers at a rock concert.
However, this noise would be the least of the problems. The sun also constantly produces very low-frequency pressure waves – vibrations that resemble seismic waves, but are much more powerful than earthquakes on Earth. If these waves were to reach our planet, they could destroy buildings and collapse bridges.
In reality, the silence we experience at sunrise is an illusion. At its source, the Sun is incredibly noisy. Luckily for us, the vacuum of space acts as a giant insulator, making dawn a quiet and peaceful experience for us. /GazdetaExpress/
