Stephen Hawking’s Final Theory About Our Universe Will Melt Your Brain

Posted by in categories: cosmology, neuroscience, physics

Nope. Too late already. It’s been molten long ago already ha…


Groundbreaking physicist Stephen Hawking left us one last shimmering piece of brilliance before he died: his final paper, detailing his last theory on the origin of the Universe, co-authored with Thomas Hertog from KU Leuven.

The paper, published in the Journal of High Energy Physics in May, puts forward that the Universe is far less complex than current multiverse theories suggest.

Why Don’t Black Holes Swallow All of Space? This Explanation Is Blowing Our Minds

Posted by in categories: cosmology, physics

Black holes are great at sucking up matter. So great, in fact, that not even light can escape their grasp (hence the name).

But given their talent for consumption, why don’t black holes just keep expanding and expanding and simply swallow the Universe? Now, one of the world’s top physicists has come up with a new explanation.

Conveniently, the idea could also unite the two biggest theories in all of physics.

If energy can’t be created, where did it come from in the first place?

Posted by in categories: cosmology, education, quantum physics

We’re taught at school that energy can’t be created, merely converted from one form to another. But at the birth of the Universe – that is, everything – the energy needed for the Big Bang must have come from somewhere. Many cosmologists think its origin lies in so-called quantum uncertainty, which is known to allow energy to emerge literally from nowhere. What isn’t clear, however, is why this cosmic energy persisted long enough to drive the Big Bang.

A cosmic fountain is just as cool as it sounds — and stunningly beautiful to match

Posted by in category: cosmology

When vast amounts of gas fall toward a supermassive black hole at the center of a galaxy cluster, gravitational and electromagnetic forces spray most of the gas away continuously for tens of millions of years. See for yourself: https://go.nasa.gov/2GfhvLd

Doctoral Student Just Published a Paper Describing How Time Travel Would Be Possible

Posted by in categories: cosmology, physics, time travel

And how to build a time machine.


The concept of time travel has always captured the imagination of physicists and laypersons alike. But is it really possible? Of course it is. We’re doing it right now, aren’t we? We are all traveling into the future one second at a time.

But that was not what you were thinking. Can we travel much further into the future? Absolutely.
