Think Quantum to Build Better AI
Investigating how quantum memory storage could aid machine learning and how quantum interactions with the environment may have played a role in evolution.

Outside the Box
A proposed quantum set-up that could predict your game-playing strategy resurrects Newcomb’s classic quiz show paradox.

The Quantum Agent
Investigating how the quantum measurement process might be related to the emergence of intelligence, agency and free will.

First Things First: The Physics of Causality
Why do we remember the past and not the future? Untangling the connections between cause and effect, choice, and entropy.

Can Time Be Saved From Physics?
Philosophers, physicists and neuroscientists discuss how our sense of time’s flow might arise through our interactions with external stimuli—despite suggestions from Einstein's relativity that our perception of the passage of time is an illusion.

Frank Drake on a $100 million Alien Hunt
Founder of modern SETI, Frank Drake, discusses the new $100 million mission to listen out for alien communications. He talks about search strategies, the Drake equation, and why he's scared the aliens are sending us holograms. In this extended interview Drake also discusses new SETI job opportunities.

Hello,it isevident that we are not alone Inside our universal sphere.Astrobiology is fascinating.There are a lot of civilizations even when we consider the number of galaxies.Some less Evolved ,others more.I beleive strongly that our actual waves Under our special relativity are not sufficient.We cannot communicate at a kind of present due to our limits of scales.We can only have a past message.If civilizations send messages, if they have the same step than us ,so we can indeed have waves.But it...

If we could change the speed of light and gravitational constants, c and G, superluminal travel would be much easier.

It is very frustrating this problem about the linear velocity of spaceships.

Already that c is not sufficient to visit and travel Inside our Milky way.We are at 27000 light years of the central BH and the lenght is 100000 light years.

It is absolutely neccesary to go fasterthan c.But it is not possible with bosons , so we must focus on gravitons produced by cosmological BH sphères.The correlated entropy is relevant.In this line of reasoning it is possible to travel between...
