By breaking a decades-old paradigm and rethinking the role that the dimension of time plays in physics, researchers from the University of Rostock and the University of Birmingham have discovered ...

So the odds that we will overlap in time and space with a detectable alien civilization don't seem great. There is probably no single solution to the Fermi Paradox The "great silence" is the idea ...

What if, in the vastness of space and time, we humans are the aliens of the future, journeying back in time? This thought-provoking concept, known as the Time Traveler's Paradox, challenges our ...

Nonlocal correlations that define quantum entanglement could be reconciled with Einstein’s theory of relativity if space–time ...

Wright said Fermi's paradox essentially suggests that—given enough time—"every alien species ... Or interstellar space could just be too difficult to traverse, the distances too vast, the ...
