Unveiling the Hidden Spaceships: Detecting Gravitational Waves from Planet-sized Alien Spacecraft

🚀Our ability to measure ripples in spacetime has led to the discovery of unexpected phenomena, such as black hole mergers and colliding neutron stars.

🌌Gravitational waves are created by the acceleration of objects with mass, resulting in a complex network of spacetime ripples.

🔭LIGO, designed to detect merging black holes and neutron stars, could potentially detect the gravitational wakes caused by planet-sized alien spacecraft accelerating to near light speed.

👽Theoretical calculations explore the mass and acceleration required for a planet-sized alien spacecraft to produce detectable gravitational waves.

🛰️Gravitational wave observatories like LIGO, LISA, and Pulsar Timing Array enhance our ability to detect and study various phenomena, including potential signals from alien spacecraft.

What are gravitational waves?

—Gravitational waves are ripples in the fabric of spacetime caused by the acceleration of objects with mass.

What has LIGO observed so far?

—LIGO has observed phenomena such as black hole mergers and colliding neutron stars.

Could LIGO detect signals from alien spacecraft?

—Theoretical calculations explore the possibility of LIGO detecting gravitational waves emitted by planet-sized alien spacecraft accelerating to near light speed.

What other gravitational wave observatories exist?

—Other observatories include LISA, a space-based observatory with longer arms, and Pulsar Timing Array, which consists of pulsars scattered across the Milky Way.

Are planet-sized alien spacecraft a plausible concept?

—While speculative, the study explores the physical conditions under which planet-sized alien spacecraft could emit detectable gravitational waves.
