Are antimatter weapons possible?
An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon. Annihilation requires and converts exactly equal masses of antimatter and matter by the collision which releases the entire mass-energy of both, which for 1 gram is ~9×1013 joules.
What can escape a black hole?
Another way to look at it is that the escape velocity from the event horizon of a black hole is faster than the speed of light. Since nothing can travel faster than the speed of light, nothing escapes the event horizon of a black hole.
What makes up the core of an antimatter weapon?
The antimatter weapon core would have to consist primarily of neutral antiparticles. Extremely small amounts of antihydrogen have been produced in laboratories, but containing them (by cooling them to temperatures of several millikelvins and trapping them in a Penning trap) is extremely difficult.
How many milligrams of antimatter would it take to get to Mars?
While tons of chemical fuel are needed to propel a human mission to Mars, just tens of milligrams of antimatter will do (a milligram is about one-thousandth the weight of a piece of the original M&M candy).
Why is antimatter used as a fuel in science fiction?
Most self-respecting starships in science fiction stories use antimatter as fuel for a good reason – it’s the most potent fuel known. While tons of chemical fuel are needed to propel a human mission to Mars, just tens of milligrams of antimatter will do (a milligram is about one-thousandth the weight of a piece of the original M&M candy).
Is there such a thing as a tabletop antimatter gun?
(Phys.org) —An international team of physicists working at the University of Michigan has succeeded in building a tabletop antimatter “gun” capable of spewing short bursts of positrons.
