If 1kg of antimatter came into contact with 1kg of matter, the resulting explosion would be the equivalent of 43 megatons of TNT – about 3,000 times more powerful than the bomb that exploded over Hiroshima.
A gram of antimatter could produce an explosion the size of a nuclear bomb.
I gram of antimatter meeting 1 gram of matter will annihilate each other, releasing 43 kilotons of energy. 1 kg of antimatter would release 43 megatons, which is just 7 megatons below the largest nuclear weapon even detonated, the Tsar Bomba.
Matter and anti-matter annihilate each other on contact, releasing energy according to Einstein's famous formula. This tells us that one pound of antimatter is equivalent to around 19 megatons of TNT.
The cost of 1 gram of antimatter is about 62.5 trillion dollars (around 5,000 billion INR).
From a catalogue of about a billion of collisions at energies of 200 GeV and 62 GeV, a total of 18 revealed themselves as antihelium-4, with masses of 3.73 GeV.
How much antimatter would our villain need to annihilate with "normal" matter in order to release the amounts of energy required for the destruction of Earth? Lots! Approximately 2.5 trillion tons of antimatter.
One of the beauties of antimatter is its efficiency. A fission reaction uses up about 1 percent of the available energy inside matter, whereas the annihilation of antimatter and matter converts 100 percent of the mass into energy.
A perfect conversion of antimatter-and-matter into energy releases 8.99 × 1016 Joules of energy per kilogram of combined matter/antimatter, which means you only need 3.1 tonnes of antimatter (and another 3.1 tonnes of matter) to power the whole world for a year.
If one ton of antimatter and matter were to annihilate each other, the resulting explosion would be incredibly powerful. 1000 kg of antimatter would exceed 42000 megatons of explosion when it interacts with matter. That's 8400 times the estimated power of the actual Tsar Bomba test.
Under controlled conditions one kilogram of TNT can destroy (or even obliterate) a small vehicle. The energy to burn 1 kilogram of wood. The approximate radiant heat energy released during 3-phase, 600 V, 100 kA arcing fault in a 0.5 m × 0.5 m × 0.5 m (20 in × 20 in × 20 in) compartment within a 1-second period.
Using the convention that 1 kiloton TNT equivalent = 4.184×1012 joules (or one trillion calories of energy), one half gram of antimatter reacting with one half gram of ordinary matter (one gram total) results in 21.5 kilotons-equivalent of energy (the same as the atomic bomb dropped on Nagasaki in 1945).
The explosion of one ton of TNT releases approximatly 4.2 × 10 12 joules of energy; for comparison, it takes almost 6.0 ×10 4 joules to warm up a cup of coffee. The Trinity test, a plutonium fueled bomb had an estimated yield of 21 kilotons, and left a crater 2.9 meters deep and 335 meters wide.
As such, the Universe should contain no matter or antimatter, and just be a sea of photons. Instead, it contains enough matter to make about two trillion galaxies and, as far as we can tell, no antimatter.
Matter and antimatter particles are always produced as a pair and, if they come in contact, annihilate one another, leaving behind pure energy.
When antimatter comes into contact with matter it annihilates: the mass of the particle and its antiparticle are converted into pure energy. Unfortunately, however, antimatter cannot be used as an energy source.
The record for storing antiparticles is currently held by the TRAP experiment at CERN: antiprotons were kept in a Penning trap for 405 days.
One such proposed technology is antimatter-based propulsion, which, as its name implies, involves using antimatter to power a spacecraft to velocities reaching a few percent of the speed of light.
Luckily, there is technology available to create antimatter through the use of high-energy particle colliders, also called "atom smashers." Atom smashers, like CERN, are large tunnels lined with powerful supermagnets that circle around to propel atoms at near-light speeds.
Which is more powerful, the antimatter bomb or a nuke? By far, the antimatter bomb. A typical theoretical (but potentially possible) design has ALL of the matter and anti-matter annihilating into pure energy. An efficient modern nuke only converts less than 1 kg of the matter into energy.
NASA spacecraft are currently powered by ion thrusters, which have top speeds of 200,000 mph. With the antimatter propulsion systems, the antimatter rocket could hit speeds of 72 million mph.
Today, antimatter is primarily found in cosmic rays – extraterrestrial high-energy particles that form new particles as they zip into the Earth's atmosphere.
Antimatter from far away should be tricky to find. It annihilates when it meets regular matter – and the more space it crosses, the more chances there are for these particles to meet their end.
Black holes can only arise from material that collapses, which means all of the black holes in our Universe must have been made from matter, not antimatter.
Yes it does, but we don't see it around us. The 'case file' for antimatter was opened in 1928 by physicist Paul Dirac. He developed a theory that combined quantum mechanics and Einstein's special relativity to provide a more full description of electron interactions.
