Para pesquisadores realidade em que vivemos pode ser simulaoGrupo de cientistas da Alemanha d vida ao roteiro imaginrio de 'Matrix'

Matrix

Aps assistir a Matrix, voc ficou se perguntando se realmente existe umuniverso paralelo gerado por um computador? Se a resposta foi positiva,

talvez esteja chegando a hora de voc descobrir a verdade.

Segundo oDaily Mail, um grupo de cientistas da Universidade de Bonn

(Alemanha) encontrou uma forma de confirmar se o universo como

conhecemos ou no uma realidade simulada.

Para confirmar a suposta teoria do 'Matrix', os estudiosos buscam criar

uma simulao de nosso universo para encontrar a natureza da"viso

restrita", que nos impediria de perceber esse universo paralelo virtual

em que (teoricamente) estaramos vivendo.

Segundo eles, possvel que alguma civilizao tenha conseguido

produzir computadores to poderosos capazes de desenvolver

simulaes do prprio universo. Sendo assim, estaramos vivendo emuma dessas simulaes, reproduzindo a mesma trajetria que nossos

Do we live in the Matrix? Researchers say they have found a way to

find out

Any simulation of the universe must have limits, and finding these

would prove we live in an artificial reality, physicists claim

By Damien Gayle

If the Matrix left you with the niggling fear that we might indeed be living in a computer

generated universe staged by a malevolent artificial intelligence using the human race as anenergy farm, help is at hand.

A team of physicists have come up with a test which they say could prove whether or not the

universe as we know it is a virtual reality simulation - a kind of theoretical red pill, as itwere.

Silas Beane of the University of Bonn, Germany, and his colleagues contend that a

simulation of the universe, no matter how complex, would still have constraints which wouldreveal it.

criadores. Ou seja, no futuro, seramos capazes tambm de projetar as

mesmas simulaes em que supostamente vivemos.

A verdade ser finalmente revelada quando os fsicos unificarem o micro

e o macro, e encontrarem nossas limitaes percepto-sensoriais que nos

impedem de enxergar a realidade. Viagem total dos tais cientistas ou

uma realidade nebulosa?

Is the real world real? Physicists say they have come up with a way of determining whether

the world we experience is actually a computer simulation, as imagined in The Matrix trilogyof films

All we have to do to identify what these constraints would be is to build our own simulationof the universe, which is close to what many researchers are trying to do on an incrediblyminiscule scale.

Computer simulations have been run to recreate quantum chromodynamics - the theory that

describes the nuclear forced that binds quarks and gluons into protons and neutrons, whichthen bind to form atomic nuclei.

It is believed that simulating physics on this fundamental level is equivalent, more or less, tosimulating the workings of the universe itself.

To put that in context, a femtometre is 10^-15 metres - that's a quadrillionth of a metre or0.000000000001mm.

However, the main problem with all such simulations is that the law of physics have to be

superimposed onto a discrete three-dimensional lattice which advances in time. And that'swhere the test comes in.

IS REALITY MERELY AN ILLUSION?

The question of whether we are actually aware of the real world is one which has been

continually asked by philosophers.

One of the earliest articulations of the conundrum occurs in Plato's Republic, where

the Allegory of the Cave attempts to describe the illusory existence led by most

unthinking people.

Plato, regarded by many as the father of Western philosophy, suggested that the only

way to come to a realisation of the real world was an in-depth study of maths and

geometry, which would give students an inkling of the real nature of the world.

French philosopher Rene Descartes, pictured above right, whose works are often used asa general introduction to metaphysics, raises the problem again as a thoughtexperiment to lead readers to a position of radical doubt.

By postulating a malicious demon who can keep us trapped in an illusory world,

Descartes asks readers to cast aside all the evidence of their sensory experiences in a

search for one certain premise.

He famously comes up with the argument 'cogito ergo sum', or rather 'I think therefore

I am', which he uses as a indubitable bedrock from which to reconstruct a certain

picture of reality.

Subsequent critics of his work, however, say that just because there are thoughts, there

is no guarantee there is really a thinker.

Professor Beane and his colleagues say this lattice spacing imposes a limit on the energy thatparticles can have, because nothing can exist that is smaller than the lattice itself.

This means that if the universe as we know it is actually a computer simulation, there ought

to be a cut off in the spectrum of high energy particles. And it just happens that there isexactly this kind of cut off in the energy of cosmic rays, a limit known as the GreisenZatsepinKuzmin (GZK) cut off.

As the Physics arXiv blogexplains, this cut off is well-studied and happend because high

energy particles interacting with the cosmic microwave background lose energy as theytravel across long distances.

The researchers calculate that the lattice spacing forces additional features on the spectrum,

most strikingly that the cosmic rays would prefer to travel along the axes of the lattice. This

means they wouldn't observed equally in all directions.

That would the acid test that the researchers are searching for - an indication that all is not at

it seems with the universe. Excitingly, it's also a measurement we could do now with ourcurrent levels of technology.

That said, the finding is not without its caveats. One problem Professor Beane identifies is

that the simulated universe could be constructed in an entirely different way to how theyhave envisaged it.

Moreover, the effect is only measurable if the lattice cutoff is the same as the GZK cutoff,any smaller than that and the observations will draw a blank.

Professor Beane and his colleagues' findings are reported in Cornell University'sarXivjournal.
