Keep pulling the thread on Michael Faraday.
China has a plan to build a large-scale solar power farm in space.
The Milky Way galaxy is on a collision course with the Andromeda galaxy, with the event predicted to occur in approximately seven billion years.
The "Big Rip" is a hypothetical cosmological model where the accelerating expansion of space eventually overcomes all forces, tearing apart galaxies, stars, planets, and ultimately atoms themselves.
The intense gravity of a black hole bends light from its accretion disk, allowing an observer to see parts of the disk that are physically located behind the black hole.
Most modern electricity generation, including from wind, steam, hydroelectric, and geothermal sources, operates by using a source of motion to turn a turbine, which generates current via electromagnetic induction.
The proposed method for transmitting energy from a space-based solar farm involves converting the electricity to microwaves and beaming them to a receiving station on Earth.
China is the world's largest consumer of coal.
"Blue straggler" stars, which appear younger than other stars in their cluster, are believed to be the result of two stars colliding and merging, which mixes their materials and provides new fuel to their cores.
A theoretical warp drive functions by warping the fabric of spacetime itself, rather than accelerating a ship through space, which would allow for faster-than-light travel without subjecting the crew to inertial forces.
The electromagnetic force is approximately 10^42 times stronger than the gravitational force.
Physicists theorize the existence of the graviton, a quantum particle that mediates the force of gravity, analogous to how the photon mediates the electromagnetic force.
The rotation direction of an edge-on spiral galaxy can be determined by measuring its spectrum, as one side will be blue-shifted (moving towards the observer) and the other side will be red-shifted (moving away).
