Description	Answer	% Correct
Invisible matter that scientists believe makes up some 25 percent of the universe and whose presumed existence accounts for how the trajectories through of visible stars and galaxies are bent.	Dark Matter	79%
A machine used to speed up streams of particles in a define direction at high speeds.	Particle Accelerator	72%
A mysterious, invisible material that has an anti-gravitational power believed to be powering the acceleration of the expansion of the universe, of which it makes up 70 percent.	Dark Energy	62%
A measure of the disorder of a system and of its constituent molecules. More specifically, in thermodynamics it is a measure of the unavailability of a system's energy to do work.	Entropy	62%
The particle which gives matter its mass. The LHC should confirm whether it exists.	Higgs Boson	59%
A sub-atomic elementary paticle with no electrical charge and very small mess that travels very close to the speed of light. They are created as a result of types of radioactive decay or nuclear reaction.	Neutrino	59%
A particle of 2 protons and 2 neutrons that is emitted by an unstable radioactive nucleus during radioactive decay. It is a relatively low-penetration particle due to its comparatively low energy and high mass.	Alpha Particle	52%
A one-way boundary in space-time surrounding a black hole. Any matter or light that falls through this can never leave, and any event inside it cannot affect an outside observer.	Event Horizon	52%
A particle with mass, made up of smaller units called quarks that are bound together. Protons and neutrons are types of them.	Hadron	52%
The phenomenon in quantum theory whereby particles that interact with each other become dependent on each other's quantum states and properties.	Entanglement	48%
High-energy, high-speed electrons or positrons emitted by some types of radioactive decay. The particles emitted are a form of ionizing radiation.	Beta Particle	45%
An idealized object that absorbs all electromagnetic radiation that falls on it, without passing through and without reflection. The radiation emitted from its body is mostly infrared light, but varies due to temperature.	Black Body	41%
An accelerator in which two beams traveling in opposite directions are steered together to induce high-energy impacts between particles in one beam and those in the other.	Collider	41%
One possible scenario for the ultimate fate of the universe, in which the gravity of the matter in the universe will one day halt and reverse the universe's expansion causing it to collapse into a black hole singularity.	Big Crunch	38%
A measure of the mometum of a body in rotational motion about its center of mass.	Angular Momentum	31%
Law that states that the redshift in light coming from distant galaxies is proportional to their distance.	Hubble's Law	28%
High speed, energetic particles originating from space that impinges on Earth's atmosphere. Some are generated by supernovas.	Cosmic Rays	24%
A hypothetical particle that is a magnet with only one pole, and which therefore has a net magnetic charge.	Magnetic Monopole	21%
The hypothesis that life on Earth was transferred from elsewhere in the universe.	Exogenesis	17%
The idea in quantum theory that items can be separatley analyzed as having several contradictory and exclusive properties.	Complementarity	0%
