Are we living in a simulation? MIT computer scientist Rizwan Virk draws from research and concepts from computer science, artificial intelligence, video games, quantum physics, and ancient mystics to explain why we may be living inside a simulated reality like the Matrix.
Simulation theory explains some of the biggest mysteries of quantum and relativistic physics, such as quantum indeterminacy, parallel universes, and the integral nature of the speed of light, using information and computation.
Virk shows how the evolution of our video games, including virtual reality, augmented reality, artificial intelligence, and quantum computing, will lead us to a technological singularity. We will reach the simulation point, where we can develop all-encompassing virtual worlds like the OASIS in Ready Player One or The Matrix—and in fact we are already likely inside such a simulation.
While the idea sounds like science fiction, many scientists, engineers, and professors have given the simulation hypothesis serious consideration, including Elon Musk, Neil deGrasse Tyson, and Nick Bostrom. But the simulation hypothesis is not just a modern idea. Philosophers of all traditions have long contended that we are living in some kind of “illusion” and that there are other realities that we can access with our minds.
The Simulation Hypothesis is the definitive book on simulation theory and is now completely updated to reflect the latest developments in artificial intelligence and virtual reality.
Whether you are a computer scientist, a fan of science fiction like the Matrix movies, a video game enthusiast, a spiritual seeker, or simply a fan of mind-bending thought experiments, you will never look at the world the same way again.

Better than you imagined...
I bought a 4'x6' from Safavieh 10 years ago and just received its replacement. I've slept on it every night and meditated on it every day. In short, I love it. It's the most comfortable surface I can imagine.
Here's what you need to know. A sheepskin is just that, animal pelt(s). The 4x6 is four pelts sewn together. It will have a sheepskin smell, which will reduce over time. When it comes, it is rolled up and in a heavy clear poly sleeve, Open the end, not the side! This way if you need to return it, you can roll and slide it right back into the shipping sleeve.
The dimensions you buy are approximate. It's a naturally variable product.
You might prefer a medical sheepskin if you live in a hot climate. The fur on these is altered to make the hairs shorter.
I think I will cover it with a bottom sheet from now on. It might last 20 years that way.

PACKAGE STUNK UP BLDG HALLWAY
I went downstairs to pick up the package from our building management office. I could smell it already. The rug was rolled up in clear plastic with one end exposed/open. From what I could touch, the rug felt soft and the color was good. But I was embarrassed to have received this and then bring it into the elevator with me. The smell was horrendous, like sewage or fecal matter.
BACKSTORY: I had ordered 2 different sheepskin rugs from 2 different brands. My first time buying sheepskin. The other has a very faint animal/hide smell that is detected only when right up against it. This Safavieh rug, however, was for a different location in the house. Even without the first rug for comparison, the smell of this one is unbearable. I've bought many wool and polypropylene rugs from Safavieh. So I did not expect a negative experience.

Great product: thick and cozy
Size: Single Pelt/2 ft x 3 ft, Color: Natural (Ivory Whiite)
This is a lovely, thick sheepskin. I’m using it to drape over a chair. It’s very soft. The color is a natural white. Arrived quickly. The price was great for such a wonderful sheepskin.

Love it!
Size: 2' x 6' (Double Pelt), Color: Linen, Size: 2' x 6' (Double Pelt), Color: Linen
Exceeded all expectations. Bigger than I imagined it would be, super soft and thick, beautiful color (Linen), and no funky smell at all. It seems very durable. After running my hands all over it, no shedding occurred. I have yet to sit on it myself, though, as my cat claimed it right away - didn't even wait for me to remove the tag! He's been there for hours and I'm thinking I've lost my snuggle buddy, so I bought two more in the smaller size so he can have his own on the bed with me at night. I am so amazed by the quality, feel, and color. I can't believe I almost let other reviews deter me from this purchase. 100% thrilled with this beautiful pelt. Absolutely recommend!
UPDATE:
I received the other 2 purchased. Just as soft, just as thick, consistent color (Linen), no shedding, no smell. They have been in use for several days now without any issues. Love them all - and my snuggle buddy is back! 🥰

It’s wonderful!!
Size: 2' x 3' (Single Pelt), Color: Brown, Size: 2' x 3' (Single Pelt), Color: Brown
The product is wonderful! You know it is real, coz the smell doesn’t go away. I use it to meditate and cannot how nicely it created the perfect comforting barrier to help elevate my experience. I however want to find alternatives coz I stopped using animal products after turning a vegetarian. The size (it is bigger in person than in the pic) and color(brown) are perfect for what I do and doesn’t need much/any maintenance!
The white however needs a lot of attention and care.I’m sure it would last a decade and the weight is just right too!
