Scientists Find First Observed Evidence That Our Universe May Be a Hologram

Physicists finds evidence from just after the Big Bang that supports the controversial holographic universe theory.

An international study claims to have found first observed evidence that our universe is a hologram.

What is the holographic universe idea? It’s not exactly that we are living in some kind of Star Trekky computer simulation. Rather the idea, first proposed in the 1990s by Leonard Susskind and Gerard ‘t Hooft, says that all the information in our 3-dimensional reality may actually be included in the 2-dimensional surface of its boundaries. It’s like watching a 3D show on a 2D television.

Why the number 137 is one of the greatest mysteries in physics

Famous physicists like Richard Feynman think 137 holds the answers to the Universe.

  • The fine structure constant has mystified scientists since the 1800s.
  • The number 1/137 might hold the clues to the Grand Unified Theory.
  • Relativity, electromagnetism and quantum mechanics are unified by the number.

Does the Universe around us have a fundamental structure that can be glimpsed through special numbers?

The brilliant physicist Richard Feynman (1918-1988) famously thought so, saying there is a number that all theoretical physicists of worth should «worry about». He called it «one of the greatest damn mysteries of physics: a magic number that comes to us with no understanding by man».

There’s gold in your brain — we now know where it came from

 

  • A unique, tiny grain of stardust has provided a look at the early universe.
  • Computer simulations point to a single neutron-star collision as a significant source of heavy metals.
  • Gold is more than bling — it’s in our neurons.
If you’ve got a thing for gold, you’d better have some money. Not only is the precious metal beautiful, but the amount of it in the universe is finite. A new study concludes that a single neutron star merger some 300 parsecs away produced a significant amount of it. «This means that in each of us we would find an eyelash worth of these elements, mostly in the form of iodine, which is essential to life,» says one of the astronomers involved in the study, Imre Bartos at the University of Florida.

Gold in particular is pretty fascinating stuff — it can even be argued that our individual existences depend on it, as astronomer Michelle Thaller explains.

Partícula X17: qué es la quinta fuerza que dicen haber descubierto científicos húngaros

Desde hace décadas la comunidad científica ha reconocido la existencia de cuatro interacciones fundamentales que controlan el Universo: el electromagnetismo, la gravedad, la fuerza nuclear débil y la nuclear fuerte.

Pero ahora un estudio húngaro asegura haber observado una quinta fuerza de la naturaleza, un hecho que podría revolucionar nuestra comprensión del funcionamiento del mundo.

El análisis fue llevado a cabo por científicos del Instituto de Investigación Nuclear de la Academia de Ciencias de Hungría (Atomki), quienes estudiaron el comportamiento de un átomo de helio excitado y cómo emite luz a medida que se descompone.

Se dice que un átomo se encuentra en estado excitado cuando alguno de sus electrones, gozando de una mayor energía, salta de la órbita que ocupaba en estado fundamental a una órbita exterior, más alejada del núcleo.

The universe may be a closed sphere and not a flat plane, a new study says

The researchers call for a ‘drastic rethinking’ of cosmology.

The universe might be curved and closed like an inflating sphere, rather than a flat plane, a new study suggests.

  • The study found that gravity bends the path of the oldest light in the universe — radiation left over from the Big Bang — more strongly than it should.
  • Scientists behind the new study say their findings present a «cosmological crisis» and call for a «drastic rethinking» of current models.
  • Other researchers say flat models of the universe are correct, and that these findings could just be a blip in the data.
