Dr. GURU speaks,
Energies are invisible interactions/forces which pass between matter, molecules, and sub-atomic particles. Energy is neither created nor destroyed, only converted into other forms.
Energy is carried by different types of Fundamental Particles called Bosons. They have the unique feature of being able to co-exist in the same space, as long as they have the same energy.
The other Fundamental Particles are called Fermions (Quarks and Leptons), which make up Matter. Protons and Neutrons both consist of three Quarks. An Electron is a single Lepton. An Electron is therefore classified as a Fundamental Particle in its own right.
Energies can be classified into 4 groups:
- The Strong Nuclear Force keeps the Neutrons and Protons together in the Nucleus of an Atom (connecting Quarks to form “Hadrons”). It is the strongest of the forces, but only acts in these very small ranges of 10-15m. Its Boson is the Gluon.
- The Electromagnetic Force keeps Electrons in their orbits around a Nucleus and Atoms together in a Molecule. It is x100 weaker than the Strong force, but has an infinite range. Its Boson is the Photon, which carries energy, in varying strengths, as part of the Electromagnetic Spectrum. Moving an Electric Charge creates a Magnetic Field. Moving a Magnetic field creates an Electrical Current. A Magnetic object creates its Field from tiny Electrical Currents in its matter at the Atomic level (Ions). An Electrically Charged object creates its own Electric Field. Magnetism is therefore created by the movement of Charge, what we can call Electricity. The two Fields run perpendicular to one another. The higher the frequency, shorter the wave-length, the greater the energy. Ultra-Violet light, X-rays and Gamma radiations are powerful enough to throw Electrons off from their orbits (Ionizing). This gives rise to health risks such as Cancer.
- The Weak (Nuclear) Force acts between Quarks and Leptons. Its strength is only 10-11 that of the Electromagnetic force and 10-13 that of the Strong force. It is stronger than the force of Gravity, although it only acts in the short range of 10-18m. Its Bosons are the W and Z Boson. These decay to produce Fermions, which continue to radioactively decay into smaller-mass Quarks and Leptons. This decay heats our planet from the inside out and allows the Sun to shine. It is used in Medical Diagnosis and Treatment, and in Carbon-14 Dating.
- The attractive Gravitational Force of Matter and Dark Matter, and the repulsive force of Dark Energy. These are the weakest of forces, but have an infinite range. Their effect is only noticeable when dealing with Astronomical Masses. We have not found a Boson for Gravity, yet we have already named it the “Graviton”. Dark Energy is not carried by Bosons.
Dark Energy makes up 70% of the total Mass-Energy of the Universe. The rest is 25% Dark Matter and only 5% normal Matter.
“Dark Matter” is thought not to consist of Fermions (Electrons, Protons and Neutrons). It does not absorb, refract, reflect, or emit any radiation. It only interacts with Matter on a Gravitational level.
“Dark Energy” acts only as the opposing force to Gravity. Some have called Dark Energy Einstein’s missing "Cosmological Constant". However, it is not in static equilibrium with Gravity. Dark Energy is what is driving the increasing rate of expansion of the Universe. This expansion has been most noticeable during the last half of the Universe’s 15 billion year existence.
The Electromagnetic and Weak forces have been unified into the “Electro-Weak force” at the huge temperatures (1015 Kelvin). At even higher temperatures (1027 Kelvin) the Strong force would become unified, and at the highest temperatures (1032 Kelvin), found at the very start of the Big-Bang, Gravity would eventually become unified. This is the Unified Field Theory.
Despite these big leaps forward, we must not forget that we have yet little understanding of what Dark Matter or Energy is. We have not unified the Strong force with the Electro-Weak force. We have not found the elusive “Higgs Boson”, which would produce the “Higgs field” needed to explain Mass. We are still far from achieving a Unified Field Theory...the “Equation of Everything”.
The GURU must now sleep.
