New evidence that our universe is a hologram

New evidence that our universe is a hologram
Strange idea, right?

Quote:One of the great mysteries of modern cosmology is how our universe can be so thermally uniform—the vast cosmos is filled with the lingering heat of the Big Bang. Over time, it has cooled to a few degrees above absolute zero, but it can still be seen in the faint glow of microwave radiation, known as the cosmic microwave background. In any direction we look, the temperature of this cosmic background is basically the same, varying by only tiny amounts. But according to the standard “cold dark matter” model of cosmology, there wasn’t enough time for hotter and cooler regions of the early universe to even out. Even today we would expect parts of the cosmic background to be much warmer than others, but that isn’t what we observe.

One solution to this cosmological problem is known as early inflation. If the observable universe was extremely tiny in its earliest moments, it could have reached a uniform temperature very quickly. Afterwards, the theory says, the universe underwent a brief period of rapid expansion, eventually leading to the universe we observe today. We don’t have any direct evidence for early cosmic inflation, but because it would solve several issues in cosmology, it is a widely supported idea.

Recently, a team of astronomers looked at data from the Planck satellite, which gathered the most accurate measurements of the cosmic background thus far. They wanted to compare fluctuations across vast regions of the sky, known as low multipole moments, with the predictions of the standard cosmological model and a model that’s somewhat stranger, a holographic one. What if everything around you, from the distant stars to your very hands, were a hologram? Like Plato’s cave, our world of solid objects and three-dimensional space would simply be a shadow of a two-dimensional reality. On the human scale a holographic universe would be indistinguishable from the reality we expect, but on a cosmic scale there could be subtle differences we might be able to detect.

In the holographic view of cosmology, early inflation is driven by interactions of the quantum field, which would slightly change the appearance of the cosmic microwave background. This is particularly true for low multipole moments, and this difference makes it possible, at least in principle, to prove that the holographic principle is true. In their paper, published in Physical Review Letters, the team report the holographic model fitting the Planck satellite data slightly better than the standard model. The results don’t prove the universe is holographic, but they are consistent with a holographic model.

The idea that our universe might be holographic comes from string theory. Although string theory hasn’t been proven experimentally, its mathematical structure has an elegance and power that makes it appealing as a theoretical model. The holographic principle in string theory is just such an example. In its broadest form, the holographic principle states that anything you can know about a particular volume of space can be learned by looking at the surface enclosing the volume. Just as a hologram can contain a three-dimensional image within a sheet of glass or plastic, the universe could contain its vast volume within a surface.

For example, imagine a road 10 miles long that is “contained” by a start line and a finish line. Suppose the speed limit on this road is 60 miles per hour, and we want to know if a car has been speeding. One way to do this is to watch a car travel the whole length of the road, measuring its speed the whole time. But another way is to simply measure when a car crosses the start line and finish line. At a speed of 60 miles per hour, a car travels a mile a minute, so if the time between start and finish is less than 10 minutes, we know the car was speeding.

If the holographic principle is true, then the universe can be viewed in two different ways: one of space and volume as we intuitively experience it, and one of a “surface” with one less dimension. This holographic duality is mathematically powerful because some laws of physics can be much easier to work with in one view than the other.

The structure of our universe is driven by the constant pull of gravity between stars and galaxies. In the present era, gravity is weak compared to other forces, and is described as a gravitational field in general relativity. In the dual holographic view, gravity is described as a quantum field that can interact strongly with mass. Since it is easier to calculate weak interactions than strong ones, the general relativity approach is more useful. However, in the early moments of cosmic time, when the universe was hot and dense, the gravitational fields of relativity were strong, so quantum fields of the holographic view might be easier to deal with.

The fact that both the standard and holographic models can account for early inflation supports the idea that the holographic principle applies to our universe. Cosmic inflation remains a mystery, but by viewing the universe as a hologram we might just be able to solve it.

As I understand it, on a meta level it is a type of structure. It doesn't have to be like a photograph, nor does it have to be a Matrix-like environment built by some being or beings outside of our spacetime.

It is more like a way of looking at matter and energy as simply information organized at a certain level in a certain way. That organization could in principle either be self-organization or at some other impetus like depicted in the Matrix (and therefore need not and should not assume deities).

In addition, none of this changes what we know, which is what it's like to experience sentience in spacetime. It is simply one way of theorizing about how that spacetime is structured. We already know for example that concrete is actually mostly empty space, but this doesn't change what it's like to experience falling on concrete from the top of a 10 story building. Gravity is a weak force and momentum is easily canceled even by something that's mostly empty space -- but that's not how a scientifically uninformed person would ever be apt to think of it, apart from the very rare Einstein-like mind.

Yabut what if the evidence they're looking at is a hologram in and of itself and not the real universe.    Silly scientists.   Tongue Wink

New evidence that our universe is a hologram
To me, the current Big Bang model needs to be modified as it really doesn't make any sense in nature.

I prefer to think of the Big Bang as being the result of a supermassive black hole, and it was localized in our part of the observable universe. It did not create the universe, but rather all expended energy from the black hole transformed naturally and eventually became the objects we see in the observable universe. As the mass and energy of a black hole shrinks, its gravitational effects on space also decreases and expansion naturally occurs. 

And it wasn't the only big bang to occur. A big bang is merely the recycling of energy and matter, first being trapped by the titanic gravitational forces, breaking all matter down to energy over billions of years, and as the black hole evaporates particles escape from the event horizon and get transformed eventually into different forms of matter and energy. Therefore, my position is that big bangs via black holes occur constantly all through an eternal universe, recycling energy and matter endlessly.

This position eliminates an origin to the universe, and solves the puzzle of "what came before the Big Bang?"

The answer? Everything.

OR a SMBH in another universe with a different time scale shows as a white hole in this universe, and all the material gathered by the SMBH is all the material we have now.

Too bad the observable facts are better explained by the big bang than by your hypothesis.
The last sentence btw is a non sequitur, as i understand it.

In the simplest sense, if matter is mostly empty space (and I agree in the sense that a baseball in a sports stadium is like a nucleus and electrons are buzzing around the seats) it is the energy field that creates the impenetrability and (in some way) mass of objects. Which is why my computer sits on the desk and doesn't just fall though.
Theists disbelieve in all deities but one.  I just disbelieve in one less.

The CMB is effectively the leftover heat of the Big Bang itself. However, at the event horizon of a black hole the material being pulled into the hole’s gravity well is accelerated to near the speed of light. The molecules of the material collide with such vigour that it is heated up to a temperature of hundreds of millions of degrees.

As a black hole evaporates, space expands and with it goes the leftover heat from the event horizon of a black hole in very much the same way the Big bang model theorizes, and that explains the CMB from a Black Hole.

This isn't my idea.

I have confidence they will come up with a very credible hypothesis for that.

As I stated earlier, if the Big Bang was actually a Black Hole, it explains a lot and it answers some very puzzling questions, such as:

Q: What existed before the universe?
A: A better question would be, "What existed before the observable universe?" The answer would be the un-observable universe. 

Q: What is the universe expanding into?
A: Again a better question would be, "What is the observable universe expanding into?" And again the answer would be the un-observable universe.

A Black Hole.

And he has advanced his theory since 2013.

You dont favour the theory which matches the data/evidence!?. Case closed.
At this point we dont need to discuss the updated black hole theory, since you obviously dont go by the evidence but by some other standard. I am interested in evidence based thinking.

Heres the data you chose to ignore, for reference

I prefer to see it as the current observations match predictions made by a black hole by nearly 96%..

Considering that a Black Hole clearly makes far more sense than a Big Bang singularity that defies all reason, and there is absolutely no evidence whatsoever of a Big Bang model singularity positively existing but there is evidence of back holes positively existing ... do you really want to talk about who has better evidence when this theory has a bird in the hand while yours only has two in the bush?

A 4% deviation in observation isn't anywhere enough to change any reasonable mind.
