What is a hologram?

What is a hologram?

A hologram is a three-dimensional image reproduced from a pattern of interference produced by a split coherent beam of radiation (such as a laser). A simple example of a hologram is a glittering hologram on your credit card.

They were successful in proving that information is not lost forever in a black hole, but is retained on the surface of the event horizon. This information stays on a two-dimensional surface of a black hole like a hologram. This in layman’s language is called the Holographic principle.

Event Horizon

Event Horizon

Event horizon — it’s the boundary of the region of space-time from which nothing in our universe could escape, not even light. It acts as a one-way portal, around the black hole. Objects or matter can fall through the event horizon into the black hole, but it’s never the other wa...

We can’t combine both of these theories. Some scientists believe the only way to do so is through the Holographic Universe principle.

At the beginning of this article, we discussed the two basic properties of matter, particularly the second one, that is to say, conservation of mass. Now we’...

Recent research on the black hole information paradox

Scientists discovered that when quantum gravitational corrections are taken into account, matter collapsing into a black hole leaves an impression in the black hole’s gravitational field. Professor Xavier Calmet of the University of Sussex described this impression as “quantum hair” in an article...

In the year 1981, the famous scientist Stephen Hawking predicted something unusual happening at the event horizon. He predicted that information is being torn apart or the information is being destroyed forever — called the Black hole Information Paradox — in turn, violating the ...

Possibilities for solving this paradox

Three possibilities arise when we try to solve the black hole information paradox, and these possibilities are:

  • The information is lost forever — then we’d need to reformulate our laws of physics
  • The information is hidden

Many physicists believe that the holographic principle will be one of the fundamental physical principles that will allow insights into a greater understanding of reality. Understanding the implications of Holographic Principle means understandin...

Holographic Principle

The idea that our Universe might be a hologram came out of the conception of String Theory.

Holographic principle According to this principle , all the information, which makes up our 3D ‘reality’ (plus time) is contained in a 2D surface on its boundaries.

Why Holographic Principle?

You might be thinking, “why we’re concentrating so much on this weird principle, right?” There are complex things that couldn’t be explained otherwise without predicting our universe and reality working as per the Holographic principle. For example, the problem of combining quantum mechanics, and...

The two stars have the same gravitational potential at the classical level, but the potential varies depending on the star’s composition at the quantum level. When stars collide to form black holes, their gravitational fields keep the memory of what they were comprised of.

Holometer Experiment

Holometer Experiment

The Fermilab Holometer is intended to be the world’s most sensitive laser interferometer, surpassing the sensitivity of even the GEO600 and LIGO systems, and theoretically able to detect holographic fluctuations in spacetime. Holometer has begun collecting data that will help det...

American physicist John Wheeler published a theory in 1973, saying Black Holes are ‘hairless’. In simple terms, it means that there is no trace of any mass around the Black Hole and nothing can be retraced from within a black hole.

Principle of Conservation of mass

In the 18th century, Antoine-Laurent Lavoisier’s work provided physics with great insight into the matter. Lavoisier along with his wife, Marie Anne, experimented with matter and came to the conclusion that matter can’t be destroyed; it just changes from one form to another. The principle became ...

The elementary particles that make up the information are same but their way or manner of binding together undergoes a change in comparison to their earlier state. )

Even the laws of nature become easy to understand when applied to two-dimensions than in three-dimensions, they say. They’ve arrived at the conclusion after a series of mathematical calculations. Don’t worry! It’s just a theoretical concept, that could come out as a reality. Live your life as you...

Blackhole Information Paradox

Blackhole Information Paradox

The relationship between matter and space gave rise to many interesting phenomena. We know two basic properties of matter — matter resists change (that’s how its mass is defined — Mass of the matter is the property that allows matter to resist a change in m...

A Laser Can Get Trapped In Water

A Laser Can Get Trapped In Water

Yes, really. A cool thing called total internal reflection is applied when pointing a laser beam through a container of water. When light travels through water, it’s slowed by the heavier particles in water,as described here. Thus, the laser beam effectively gets “trapped” in the water.

A Contradiction or What?

- Meaning, at the same time and at the same placement there were two states, it was interference pattern and particle pattern and it was coming from one typical of source which was quantum entity (electron, photon, etc). And there was no distance in between the two states. It was definitely contr...

Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.

Ashley Anthony

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

Jamyson Haug

Great for quick bits of information and interesting ideas around whatever topics you are interested in. Visually, it looks great as well.
