The increasingly regional scope of Collide
this year reflects strengthening relationships with Coventry and Wolverhampton city councils and Sandwell Metropolitan Borough Council.
If dark matter particles can collide
and interact, these processes should be reflected in the distribution of dark matter on larger scales.
Gamma rays that collide
with lower-energy radiation sometimes vanish, leaving pairs of electrons and positrons in their wake.
Black is always in style,'' said Michael Ortega, Futures Collide
collector and manager.
Because galaxies are known to collide
with each other, scientists suspect the galaxies' black holes also crash together sometimes.
As the galaxies collide
and pass through each other, their dense clouds create a magnetic bridge, stretching out their magnetic field lines much as a taffy machine pulls taffy, Condon says.
A similar fate may befall our own galaxy, which is expected to collide
with Andromeda, its nearest spiral neighbor, several billion years from now.
In the absence of sunlight, atmospheric gases freeze onto the moon's surface and electrons have fewer particles with which to collide
, Geissler's team explains.
Officials with the National Transportation Safety Board said it was unclear what caused the planes to collide
In one scenario, material falling toward the black hole generates high-energy photons, which collide
to produce pairs of electrons and positrons.
It remains unclear, says Simon, how the storms managed to collide
despite being separated by a vortex rotating in the opposite direction.
One possible explanation of the gamma rays' origin, Dixon says, is that they are created when electrons traveling near the speed of light collide
with lower-energy, infrared photons.
