Can Black Holes Compute Universes?

In summary, the article discusses the idea that everything in the universe computes, with even the tiniest particles exchanging bits of information when interacting with each other. However, the article also questions how this is possible given the uncertainty of quantum mechanics. It also explores the concept of black holes as powerful computers, with the average supermassive black hole having the potential to make calculations equivalent to the entire history of the universe in a fraction of a second. The article ends with the idea of creating artificial microscale black holes and the potential for even more advanced computing capabilities.

Computing By A Black Hole!?

I have recently read the november edition of Scientific American.
The article says that everything computes.
Bits like momentum ,angular momentum exchange when particles interact with each other.
But how does it encode matters as quantum mechanics effect exists?I can't really be certain of particles momentum and position.
And more professionally do black holes output information we need?And according to which theory?
And then WHY we don't just put matters into an ordinary matter ?Black holes have any specific property?

black holes by definitions perform chaotic computations in Planck-time at Beckenstein's bound-

I have been very intrigued of late that according to Seth lloyd the observable universe represents 10^90 bits of information and the universe has performed 10^120 operations since the Big Bang [ http://www.kurzweilai.net/meme/frame.html?main=/articles/art0530.html ] given the computational nature of Black Holes- the average supermassive type black hole could easily nmake computations of this magnitude and beyond - the information density of a black hole is by definition at the Beckenstein Bound of 10^66 bits per sq cm- a super massive black hole has a radius of around 10^9 km- which makes the surface area around 10^19 sq km- with 10^66 bits per sq cm- the black hole stores 10^76 bits per sq km- that is... 10^95 BITS total! [remember the universe is 10^90 bits]- and a supermassive black hole lasts for googolplexes of aeons- yet performs operations at Planck time- 10^43 flops per second [therefore processing 10^138 bits/sec] and will keep calculating at this rate for near eternity- as you can see- a supermassive Black hole CAN compute universes like ours quite comfortably indeed- in fact the entire history of our universe could be calculated within one-quintillionth [10^-18] of a second! hmmmmmm

it is also promising to think what may be possible with computation if we are succesfully able to create artificial microscale black holes at the LHC-future computers might make unfathomably vast computaions with the brief poof of hawking radiation from the rapid evaporation of networks of microscale black holes

1. What is "computing by a black hole"?

"Computing by a black hole" refers to the concept of using the extreme gravitational pull of a black hole to perform computational tasks. This is based on the theory that black holes have immense computing power due to their ability to process and store vast amounts of information.

2. How does computing by a black hole work?

The exact mechanism of computing by a black hole is not fully understood, but it is believed that the intense gravitational pull of a black hole can manipulate and process information on a quantum level. This is due to the black hole's ability to warp space and time, allowing for complex calculations to be performed.

3. What are the potential applications of computing by a black hole?

The potential applications of computing by a black hole are still largely speculative, but some scientists believe it could be used for tasks that require massive amounts of processing power, such as weather forecasting, simulations of complex systems, and encryption.

4. Are there any challenges or limitations to computing by a black hole?

One major challenge is the ability to control and harness the extreme environment of a black hole. The intense gravitational forces and high levels of radiation make it difficult to send and retrieve information from a black hole. Additionally, the technology required to utilize computing by a black hole is still largely theoretical and has not been tested.

5. Is there any current research or progress being made in computing by a black hole?

While the concept of computing by a black hole has been proposed for decades, there is currently no concrete evidence or technology to support its feasibility. However, some scientists are continuing to explore the possibilities and potential applications of using black holes for computing.
