Why is antimatter fascinating ?

Why is antimatter fascinating ? When antimatter meets its matter twin They annihilate in flash of light

Result of one electron and one positron annihilating at CERN…..

….or many annihilating inside a physicist’s brain At low energies, electron- positron annihilations can reveal the workings of the brain in the technique called Positron Emission Tomography (PET).Positron Emission Tomography This image is of the brain of one of the physicists working with high-energy electron-positron collisions at CERN.This image

1 gm antimatter = Hiroshima Theme of Angels and Demons (a work of fiction) Demonic Antimatter? 20 gm

1 gm antimatter = Hiroshima Theme of Angels and Demons (a work of fiction) Demonic Antimatter? 20 gm TRUE ……. in principle Technology etc = liberate it for use Chemistry 1/1000 Nuclear fusion 1/100 Annihilation 2/1 !! Matter (and antimatter)= Congealed Energy

Result of one electron and one positron annihilating at CERN….. Looks dramatic but energy is less than a puff of air. The drama is that it is concentrated in just ONE particle - antiparticle

Result of 1 gm electrons and positrons annihilating ….. Looks dramatic but energy is less than a puff of air. The drama is that it is concentrated in just ONE particle - antiparticle Bulk annihilation involves all together. “non-trivial”

CERN is now regularly producing small quantities of antimatter in their research for future energy sources. Dan Brown interview:

Of course, mastering antimatter technology brings with it a chilling dilemma.

Dan Brown interview: Will this powerful new technology save the World? or Will it be used to create the most deadly weapon ever made?

Dan Brown interview: Will this powerful new technology save the World? Physics Teachers: Use this for discussion of Energy: First Law of Thermodynamics (Conservation) Second Law of Thermodynamics (Waste)

Could one ever make an antimatter bomb?

Could antimatter ever power space craft?

Could one ever make an antimatter bomb? Could antimatter ever power space craft? Did a lump of antimatter hit Tunguska in 1908?

Angels and Demons is fiction. What are the facts?

High energy antiparticles

Antiparticles and the Big Bang at CERN At CERN: 27km circular accelerator (LEP) Electrons and positrons collide head on at near to the speed of light. Simulates (just after) Big Bang Creation of matter and antimatter = quarks antiquarks; electrons positrons…

Energy of Big Bang turns into……

MATTER ANTIMATTER

We don’t know why the BB happened. We do know what happened afterwards. These CERN experiments have NOT “proved Creation from nothing” (ignore cod-theology; science investigating HOW ?; not same as “WHY?”)

We don’t know why the BB happened. We do know what happened afterwards. And theres a BIG PUZZLE

Antimatter and Star Trek: 1,000,000,000,000,000,000,000,000 antiatoms

Antimatter and Star Trek: 1,000,000,000,000,000,000,000,000 antiatoms At 2 million per second

Antimatter and Star Trek: 1,000,000,000,000,000,000,000,000 antiatoms At 2 million per second =10 billion years

Antimatter and Star Trek: 1,000,000,000,000,000,000,000,000 antiatoms At 2 million per second =10 billion years …and you also need to store them….

Antimatter Magnetic Bottle 1 million max stored. A billion billion bottles = store 1 gramme

Antimatter and Star Trek: Fact or Fiction?

The New Mexico company Positronics Research, has calculated that a spacecraft running on antimatter fuel equal in mass to that of a grain of rice could travel to Mars and back. Antimatter and Star Trek: Fact or Fiction?

Antimatter can never be used as a fuel You have to make it one atom at a time….. Unless there is bulk antimatter out there

Tunguska 1908 Antimatter??? (No…..a comet)

Tunguska – Antimatter would leave traces. Radio isotopes C13… From antiproton annihilations Nuclear detectives Nothing found

Air Force pursuing antimatter weapons Program was touted publicly, then came official gag order Monday, October 4, 2004

Dan Brown interview: Of course, mastering antimatter technology brings with it a chilling dilemma.

Antimatter is Science Fact But making 1gm of antistuff Is Science Fiction and it costs more energy to make than you can ever get back, so it’s useless for solving world’s energy needs. Antimatter
