Ask Ethan: Is antigravity even possible?

Realistic solutions for gravity in space travel must comply with General Relativity.

Can Space and Time Exist as Two Shapes at Once? Mind-Bending Experiments Aim to Find Out

The problem of quantum gravity highlights the need to understand gravity's quantum nature to explain extremes like black holes and the early universe.

Michio Kaku Demystifies the God Equation: The Key to Understanding Everything

The quest in physics centers on unifying general relativity and quantum mechanics into a single framework, famously known as the 'God equation.'

A Warp Drive Breakthrough Inches a Tiny Bit Closer to 'Star Trek'

The discovery of a possible physical warp drive adhering to known physics principles but without exceeding the speed of light is a significant advancement.

Your head lives a longer life than your feet do

Time is relative and influenced by speed and gravity, which causes different experiences of time for different observers.

Black Holes May Actually Be "Frozen Stars," Scientists Claim

Black holes could be 'frozen stars,' resolving the black hole information paradox and challenging existing theories of general relativity.

Astronomers Puzzled by Inexplicable Deep Space Object

Astronomers have discovered an object that falls into a 'black hole mass gap,' too heavy to be a neutron star but too light to be a black hole.
This discovery challenges current theories about the formation and classification of celestial objects, and could lead to a reevaluation of Einstein's theory of general relativity.
