A couple of years ago , the idea of mind uploading , i.e uploading the entire human brain into a Super Computer evolved which gained the attention of many computer scientists and futurists across the globe.
In the coming future this might become a reality , then we'll also see the end of Modern Silicon Era.
But would we ever be able to build quantum computers that can predict the future and challenge the mind of God? Well this idea is still in the initial stages of its development but here's the glimpse of how this could be done.First you have to understand that each one of us have a different picture of reality in our brains . Just like every person have different fingerprints , every person have different brain-reality interface.
The very first step is to build a Super Quantum Computer . Big IT firms are already working in this field and we already have our very first D-wave quantum computer by D-Wave Systems, Inc.
The second step , As I mentioned upload the entire human brain of a living person 'A' into that computer , his emotions , memories , behaviour,opinions etc.
Now in one way the computer thinks and sees the world the way A does.
We would repeat the same process with another person B and upload his brain into the same computer .
Now A of the real world have its own picture of reality, The only person in the universe that could predict his next words is A himself and this applies to B and in fact to any living brain.
But our quantum computer will process both the brains simultaneously using its super quantum parallel processors. So we've created an entity that could read both the brains at the same time!
Also that means that this computer can simulate how the two brains interact with each other in the virtual as well as in the real world .
Again we'll repeat the process with C and D to form a family of four . Ultimately we've got four virtual brains and four real ones existing independently in the real world but are a part of the same process in our quantum computer!
The next and the most important step is the simulation ; simulation of how non-living objects interact with different mechanical forces . Well you'll be surprised to know that this technology already exists and we can actually simulate how real world objects respond to different forces in our silicon based computers .
Combining these two technologies we can build a virtual world , exactly similar to ours , One you and one me can in one way exist simultaneously inside a computer and in the real world .
So how would this help us to build a Time machine ?
Consider this simple experiment -
A,B,C and D are four people(as mentioned above) who are strangers to each other .
I have invited them to my house and all of them have accepted the invitation.
Every corner of my house is already programmed into our time machine and so does the brains of A,B,C and D .
Before they actually arrive we'll run our time machine and simulate their interaction with each other in the virtual world. So what we've now on our computer screens is the Future of A,B,C and D before they actually arrive .
Now I'll wait for them to actually arrive and keep a watch on them from a hidden camera .
If algorithm works out perfectly ,what I would see would be exactly how the computer simulated it few minutes ago before they actually arrived !
This might be our first step towards building the first practical Time Machine.
Though it has some major drawbacks. In the above experiment we've excluded the interference of any other factor like cell phones ,power cut offs. Storms etc that might have influenced the decisions of any person . This was a simple experiment conducted in the most isolated environments.But this is just the beginning !In the near future we might be able to simulate the future of a society,a state,a country,the earth, and may be the Universe!
