Can a computer simulate itself?

No, a computer cannot perfectly simulate itself in addition to something else without violating basic information theory: there exist strings which are not compressible.

Is the Big Bang realistic?

Here are the most (and least) realistic. The Big Bang Theory took pride in how fairly accurate its “science talk” was. The show even used real science to come up with its own theories. For the most part, the storylines, both scientific and those related to the character’s personal lives, were resounding successes.

What was created as a result of the Big Bang?

The universe was born with the Big Bang as an unimaginably hot, dense point. As space expanded, the universe cooled and matter formed. One second after the Big Bang, the universe was filled with neutrons, protons, electrons, anti-electrons, photons and neutrinos.

What is simulation software used for?

Problem Solving and Decision Making with Simulation Software Simulation is a decision analysis and support tool. Simulation software allows you to evaluate, compare and optimize alternative designs, plans and policies. As such, it provides a tool for explaining and defending decisions to various stakeholders.

What is the advantages of simulation?

Simulation allows you to explore ‘what if’ questions and scenarios without having to experiment on the system itself. It helps you to identify bottlenecks in material, information and product flows. It helps you to gain insight into which variables are most important to system performance.

Is this the most detailed simulation of the universe ever?

Researchers have created the most detailed simulation of the history of the universe, complete with exploding gas clouds, swirling galaxies, ravenous black holes and countless stars – born to die in violent supernovae that blast the chemical elements for planets and life out into the cosmos.

How will the simulation help scientists test their theories?

The simulation draws on the laws of physics and theories for the formation of galaxies and stellar evolution to recreate a large part of the universe from 12m years after the big bang until today, nearly 14bn years later. It will help scientists test how well their theories of the universe work,…

What can we learn from simulations of galaxies?

The simulation is the first to show both large-scale structures such as the distribution of gas, and small-scale features such as the number and chemical signatures of stars in each galaxy. The scientists checked their simulation against images taken by the Hubble Space Telescope and found remarkable agreement.

What drives the expansion of the universe?

The computer model simulates the behaviour of dark matter, the invisible material that coalesced in the early universe to form a cosmic web, and dark energy, the mysterious force that drives the expansion of the cosmos. As the universe evolves, the first galaxies form with fledgling suns and supermassive black holes at their centres.
