Physicists in France and Australia believe that they have the answer to the old enigma: what came first, the chicken or the egg? And your answer may surprise you, or just confuse you even more.
The question was first raised in Ancient Greece as a way of describing the problem of determining cause and effect.
While some say that the egg was first and others believe that the chicken was first created, a group of physicists from the University of Queensland and the Neel Institute argue that both the egg and the chicken were the first.
They say the answer is in quantum physics.
Dr. Jacqui Romero explained to News.com.au that in quantum physics, the cause and effect were not always direct and did not mean that one caused another.

The researchers said that in quantum physics cause and effect does not necessarily mean that one event has caused another to happen.
"The rarity of quantum mechanics means that events can happen without an established order," he said.
Romero used a person's trip to work as an example. If a person sets up a bus and then a train to work, that means they had to take the bus first and the train the second.
According to Romero, that is not the case in quantum physics.
"In our experiment, these two events can happen first," he said. "This is called" undefined causal order "and it is not something we can observe in our daily lives."
The researchers used a device called a photonic quantum switch to observe their theory in a laboratory that uses photons.

Dr. Fabio Costa told the source that by using the device they noticed that the order of the events or the transformations in the shape of the light depend on the polarization.
"By measuring the polarization of the photons at the output of the quantum switch, we were able to show that the order of the transformations in the shape of the light was not established," he said.
"This is only a first proof of principle, but on a larger scale, the indefinite causal order may have real practical applications, such as making computers more efficient or improving communication."
The study is obviously based on physics, and differs with other theories floating around.
