Are we living in a simulation? The idea that we might be living in a simulated reality has worried us for centuries. Thomas Anderson - otherwise known as Neo - is walking up a flight of stairs when he sees a black cat shake itself and walk past a doorway. Then the moment seems to replay before his eyes. Just a touch of déjà vu, he thinks.

Mathematicians say they proved reality is real. Researchers say it's impossible to use algorithmic computation to generate everything in our universe. Breakthroughs, discoveries, and DIY tips sent every weekday. Despite how it may feel some days, we probably aren't stuck in a computer simulation . An international team of mathematicians says that they have once-and-for-all determined that our reality is, in fact, .

In classic blockbuster film'The Matrix', humans are enslaved by AI because it wants our body heat to power its computers. While this sounds straight from the annuls of sci-fi, a physics professor says we may be living in a Matrix-style simulation. Melvin Vopson, an associate professor in physics at the University of Portsmouth, thinks a series of daily clues suggest this world is not what it seems. Now, he has tackled the hypothetical and philosophical question: If we are living in a virtual simulation, what is the purpose of it? Speaking exclusively to MailOnline, he outlines three theories, including that we all chose at birth to become characters in an advanced AI world.

If you feel like you're living in a convincing virtual reality akin to The Matrix, a scientist thinks you may well be right. Melvin Vopson, an associate professor in physics at the University of Portsmouth, claims our entire universe may be an advanced computer simulation. And the proof that this so-called simulation hypothesis is correct may be hiding in plain sight in the Bible. Professor Vopson told MailOnline: 'The bible itself tells us that we are in a simulation and it also tells us who is doing it. 'It is done by an AI – an artificial intelligence.'
