In 2009. physicists believed that Our Universe Is One Big Hologram, And They May Have Spotted the Pixels:

However, this year they have proved that universe Most Likely is Not Made Out of Quantum Pixels, which disproves universe being a quantum computer simulation:

And when how did they concluded that quanta are like pixels, I realized they didn't actually see this, but rather they gave their own bold conclusions without any proof.
The problem here is these write ups are based upon other peoples own hypothetical conclusions, in this instance that a posed Planck unit is a Quantum Pixel.
A model I've been posing doesn't attempt to work with a particle as being the building block of the universe, in fact it concentrates on the notion of a very uniform suggestion:
1cm[sup]3[/sup] of Vacuum space.
Why 1 cm[sup]3[/sup]?
It's a defined measurement using an industry standard measurement. It doesn't deal with one composite, in fact, it's intentionally a construct of that volume that can support many particles and elementary bodies.
The posed reasoning is that 1cm[sup]3[/sup] has an upper limit to how much energy can ever be contained within that volume, it's similar to how water isn't compressible but the notion is you can't compress energy any further than a set level.
The reason for this I imply is down to "non-volatility", in essence if you could keep compressing energy into a volume without ever reaching a limit, however some part of that energy is "violating" the principles of other parts to reach that compression threshold (I'm pretty sure this would upset some Newtonian laws).
Non-volatility is also important in "data integrity", after all you wouldn't want important data being over-written because there wasn't enough space, so a similarity is assume between the two.
Also 1cm[sup]3[/sup] is just a reference of "Scaling", for instance you can create a virtual space in some CAD software that has 1cm[sup]3[/sup] as your model space. This doesn't mean that it's really 1cm[sup]3[/sup] in size, after all it's a representation in a virtual space, in fact you can subdivide the measurement as many times as you like, you can still call it 1cm[sup]3[/sup] but you could scale objects that are far large into the volume, like the model of a car etc.
The other point about this volume is that it doesn't have to be run in one computer, it can be a cluster of computers running that one volume and even then there can be "mirrors" (parallel copies) of that volume run on other clusters, with all clusters "compositing" their output to generate a "multiworlds view" of that volume. (such compositing would explain Quantum String Theory, Particle-Waveform Duality along with many other subatomic artefacts that currently people don't have a full working model for.)
Incidentally current computers use Binary (0/1), Q-bit Computers hypothetically use a far greater base because of identifying polar orientation.
