A new paper shows that the recent discoveries of exoplanets combined with a broader approach to the question makes it possible to assign a new empirically valid probability to whether any other advanced technological civilizations have ever existed.
A theoretical study has analyzed a model that saves special relativity and reconciles it with granularity by introducing small-scale deviations from the principle of locality demonstrating that it can be experimentally tested with great precision.
It takes a bold person to declare that interstellar travel is now within our grasp. Physicist Stephen Hawking has shown that he is just that, taking part in the Breakthrough Starshot initiative.
The genius of Albert Einstein lead us to gravitational waves - maybe someday another genius will work out how to make them, says Dr Karl.
With the full suite of observations of the Universe now at our disposal, what is the story, contents, and history of the Universe?
For some, the idea of realistically achieving the ability to travel through time is a thankless pipe dream. For others, each passing day is but another 24-hour block of dreaming about how to best alter history once the surely inevitable technology comes along to make time travel as easy as swiping a bus pass.
A landmark day for Einstein and our understanding of the universe: the detection of gravitational waves. Brian Greene explains the discovery.
Rumor has it that gravitational waves might be detected soon - a late triumph for Einstein
Black holes are not as black as we once thought. They are theorized to die a slow death by evaporation, emitting energy known as Hawking radiation. But the mechanism for evaporation is not well understood. Then again, no one has ever even directly detected a black hole.
A new theory suggests a shorter secondary inflationary period that could account for the amount of dark matter estimated to exist throughout the cosmos.
In the last few decades, researchers have pursued the problem in two separate programs—string theory and loop quantum gravity—that are widely considered incompatible by their practitioners. But now some scientists argue that joining forces is the way forward.
The theoretical physicist discusses the expanding universe and the infinite possibilities it brings.
Cause always leads to effect — except, of course, in particle physics.
An international team of scientists have crunched the numbers and discovered something straight out of science-fiction: They claim that the center of our galaxy could host a giant wormhole.
The physicist predicts densities of up to 1 billion times greater than normal.
