Astronomers search for sources of mind-bending gravitational hum permeating the universe A massive hum of energy pervades the universe. Is it supermassive black holes or something weirder?

The change in gravitational energy of the mass should be equal to the change in thermal energy of the water. OK, we actually already know this relationship. But it's still fun to reproduce it.

What are gravitational waves? – Millie, age 10, Sydney What a great question Millie! To answer this we have to travel back in time, to the year 1916. This is the year famous physicist Albert ...

Instead, if that renewable energy lifts a massive train uphill, it turns about 80% of that energy into gravitational potential energy, storing it until needed.

A science education center opens for visitors to the Hanford LIGO observatory near Richland, Washington. Gov. Inslee helped open the $8.1 million center on gravitational waves in space.

A new experiment looks to use gravitational waves – tiny ripples in the fabric of spacetime – to unlock the truth of why the universe is expanding so quickly and so unexpectedly.

Energy Vault secured $100 million in Series C funding for its EVx tower, which stores gravitational potential energy for grid dispatch.

Australian renewables startup Green Gravity has teamed with underground mining contractor RUC to accelerate the commercialization of its gravitational energy storage tech.
