The team concluded that the recoil of the remnant of GW190412 surpassed 50 km/s – enough to expel the black hole from a ...

For the first time, scientists measured a newborn black hole that "kicked" off into space after 2 larger black holes merged ...

The first successful measurement of the speed of light took place in 1676. Danish astronomer Ole Rømer was trying to measure the orbit of Io, Jupiter's third largest moon, by watching how long it took ...

Knowing the direction and speed of moving objects is often critical for survival. However, it is poorly understood how cortical neurons process the speed of image movement. Here we tested MT neurons ...

Almost all measurements of motion in astronomy make use of a law of physics called the Doppler effect. This change in the wavelength (or frequency, color, or pitch) of a wave emitted by a moving ...

The motion of any object is relative. On Earth we tend to ignore that, because the vast background of the ground gives us a seemingly fixed and absolute frame of reference. Sitting comfortably at our ...

This is really a lab that I have students do, but I am pretty sure they don't read this blog - so it is ok. If they are reading this, hi! We have these projectile cannons that shoot small balls. In ...

When Galileo's name comes up, most people think about his contributions to observational astronomy. However, he did lots of other stuff including investigating the speed of light. During his time, ...

Two black holes merged together 2.4 billion light years away from Earth, and scientists have just figured out how fast the newborn ricocheted, and in which direction.

You can use chocolate, cheese, or even marshmallows to microwave at the speed of light. Your microwave has its wavelength listed somewhere, and it's easy to multiply the rest. Also, you can still eat ...
