It seems we finally understand something about black holes and their behavior.

A new paper argues that nothing ever really falls into a black hole thanks to extreme time dilation and frame dragging.

A new estimate for the energy required to power a warp drive puts the theoretical technology well within the realm of plausibility.

If aliens want to go really, really fast, there's a small chance we could catch them in the act.

A new paper says that warp drives could bathe planets in apocalyptic radiation storms, but how it arrives at this conclusion raises a lot of questions.

For decades, scientists thought that a habitable world needed a large moon to act like a rudder. That idea might not actually be true.

Just like supermassive black holes, planets can bend light with their gravity. But do they bend it enough for us to detect them that way?

How big are some supermassive black holes? Just trying to scale them down to numbers we can wrap our minds around is a challenge in and of itself.

An Italian mathematician is trying to replace dark matter observation by playing with models of gravitational measurements.

Cosmologists are still puzzling over faint signals in the CMBR that may or may not be there and indicate profound events in our past or to our future.

We're here for an exciting time, not a long time. And we should use that time doing something fun and constructive.

Another day, another exercise in nearly unfalsifiable numerology from arXiv...

A trio of physicists want to marry dark matter and antimatter. It's not a union that seems destined for bliss.

For inflation to remain cosmology's top theory of how the universe grew into what we see today, we need to find the right gravitational waves in experiments ramping up to do just that.

Continuing the trend of looking too closely to CMBR maps, a group of cosmologists says they found evidence of "bruises" from collisions with other universes.
