In a first, CERN physicists succeeded in observing matter-antimatter imbalance in baryons, fundamental particles that make up ...

The map uses data from the Sloan Digital Sky Survey, a project to create a 3D map of the universe using a telescope at Apache Point Observatory in New Mexico.Running in various forms since 2000 ...

Start with the laws of physics, a Universe full of a specific amount matter and radiation, and a hot, dense, expanding, and mostly uniform state, and wait. 13.8 billion years later, you'll have a ...

The Universe Has Almost 10 Times More Galaxies Than We Thought : The Two-Way A new study finds there are about 2 trillion galaxies in the observable universe, up from about 200 billion. It's the ...

The observable Universe is best thought of as a series of spherical shells, centered around our planet, where most of our observing happens (plus or minus a few astronomical units).

How did everything begin? It's a question that humans have pondered for thousands of years. Over the last century or so, ...

That is, the observable universe is a spherical volume (a ball) centered on the observer. Every location in the Universe has its own observable universe, which may or may not overlap with the one ...

Beyond the observable universe lie “unknown unknowns”: the subject of speculation rather than direct observation. 1 The 45.7 billion light-year radius includes only light sources.

However, given the enormity of the universe, even that incomprehensible number doesn't fill up much of the total volume. If there are 3.28 x 10 80 particles in the universe, that means there is ...

The observable universe is still huge, but it has limits. That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago.
