One of the most used theories to deduce and try to explain the origin of the universe is that of the Big Bang. However, it is not the only one and there are several others, such as the one that suggests a continuous movement of expansion and retraction of the entire space.

The truth is that until today it is not possible to hit the hammer on what would be the best theory of all about the emergence and development of the universe. However, the Big Bang remains one of the main and perhaps the most accepted among the entire scientific community.
The most impressive thing is that one of the pieces of evidence that most helped in the process occurred because of a little excrement of pigeon.
Pigeon poop helps demonstrate Big Bang theory; understand
Physicists Amo Penzias and Robert Wilson were trying to measure radio waves from other galaxies in 1964. The search was not specific, it was just limited to finding any signal from outside to know what was noise and what was legitimate emission.
Therefore, the duo had the objective of filtering out all the noise, such as military waves, radio stations, emissions from the sun and several others. Thus, it would be easier to identify something completely new.
Even after eliminating all the noise, an interference remained. The signal did not change no matter which way the antenna was pointed. Therefore, they discarded it as something that could only come from the Milky Way.
It was then that they believed that the noise was linked to some kind of defect or interference in the antenna itself. They cleaned the object and removed the pigeon nest that was there as well.
Other physicists came to the meeting to help the pair. That’s because it was believed that the original radiation of the Big Bang could be perceived anywhere in the universe until today. They saw that the permanent noise was not pigeon droppings, but that it could be something that is everywhere all the time.
Thus, the Big Bang gained its first stronger evidence in academia. Curious, isn’t it?
