Astronomers Will Get Gravitational Wave Alerts Within 30 Seconds
Any event in the cosmos generates gravitational waves, the bigger the event, the more disturbance. Events where black holes and…
Here’s Why We Should Put a Gravitational Wave Observatory on the Moon
Scientists detected the first long-predicted gravitational wave in 2015, and since then, researchers have been hungering for better detectors. But…
Gravitational Waves Could Show us the First Minute of the Universe
Astronomers routinely explore the universe using different wavelengths of the electromagnetic spectrum from the familiar visible light to radio waves…
The Echoes From Inflation Could Still Be Shaking the Cosmos Today
In the very early universe, physics was weird. A process known as "inflation," where best we understand the universe went…
Astronomers are Hoping to Detect Gravitational Waves Coming from Supernova 1987A
