Astronomers have witnessed for the first time a violent cosmic collision in which one galaxy pierces another with intense ...

describes a scenario in which the density of space debris becomes so high that collisions between objects trigger a cascading ...

A n experiment has visualized a prediction about objects traveling at the speed of light known as the Penrose-Terrell Effect, first made over 60 years ago.

"As long as we are emitting greenhouse gases, we are increasing the probability that we see more collision events between objects in space," Parker said. Until recently, the effects of greenhouse gas ...

Collisions, explosions and impulse ... depend on the relative motion of the observer and the object. The expanding Universe The Doppler effect causes shifts in wavelengths of sound and light.

The latter stimulus mimics the effect of self-motion, and so it seems likely that self-motion, and hence information about impending collision with stationary objects, is processed in separate ...

Neutron star mergers are collisions between neutron stars ... However, most of these theoretical works did not consider the effects of magnetic fields on this spectrum. "Next-generation ...

which slows down space objects, causing them to decay faster. "The cascading effect of collisions between space debris, known as Kessler Syndrome, creates even more debris, increasing the risk of ...

An object being fired from a cannon is also a collision where momentum must be conserved. As the momentum before the 'collision' is zero, the momentum after the collision is zero. In physics ...
