Are We Living Inside a Computer Simulation?

The popular film trilogy, The Matrix, presented a cyberuniverse where humans live in a simulated reality created by sentient machines.

Now, a philosopher and team of physicists imagine that we might really be living inside a computer-generated universe that you could call The Lattice. What’s more, we may be able to detect it.

"Welcome to The Lattice.” Yes, the Lattice. Sorry, The Matrix was WAY better. The Lattice sounds like a Lifetime remake… read more.

…and, ultimately, it’s where everything will end up.

A Galaxy Far, Far Away is Furthest in Universe:

A new celestial wonder has stolen the title of most distant object ever seen in the universe, astronomers report. The new record holder is the galaxy MACS0647-JD, which is about 13.3 billion light-years away. The universe itself is only 13.7 billion years old, so this galaxy’s light has been traveling toward us for almost the whole history of space and time.

Far. Out.

The Four Ages of the Universe — What’s Next?

The Greek poet Hesiod described the Five Ages of Man in mythology.

They progress from the Golden Age, when people lived among the gods, through the warlike Bronze Age and on to the Heroic Age. His narrative ends with the Iron Age, a period of toil and misery for mankind.

Science has now replaced these mythologies. We are at the point where we look at the entire universe as a grand series of game-changing leaps toward our emergence as an intelligent species. It is an epic story more compelling than anything from creation mythology.

Why Does Our Universe Have Three Dimensions?

Why does our universe look the way it does? In particular, why do we only experience three spatial dimensions in our universe, when superstring theory, for instance, claims that there are ten dimensions — nine spatial dimensions and a tenth dimension of time?

Japanese scientists think they may have an explanation for how a three-dimensional universe emerged from the original nine dimensions of space. They describe their new supercomputer calculations simulating the birth of our universe in a forthcoming paper in Physical Review Letters.

Before we delve into the mind-bending specifics, it’s helpful to have a bit of background.
