Artron Energy is a form of psionic/temporal energy that is the energy of thought and perception - thus it is the very stuff of History itself. Because of this Artron energy can be used to translate thoughts and emotions into History itself. Artron energy is both technological and barely distinguishable from Time Lord Biology. Artron energy per unit time is measured in units called Omegas. A common rat can generate one atto-Omega (1 x 10-18 omegas) of Artron Energy. Artron Energy can be maser-modulated into thermal energy. When converted, the thermal energy of one atto-Omega is enough to instantly kill a cat. From this is can be determined that one Omega equals (within an order of magnitude) about 3x1021 watts. Artron Energy's crystallizing abilities could make it a kind of anti-entropy. The White Guardian is the Guardian of order and structure - the opposite of Artron Energy. It is possible that Artron Energy is connected to him in some way.

Since it is resistant to the effects of the Space-Time Vortex, it is the primary energy used in TARDISes. Because of this a TARDIS generates a low intensity telepathic field. The power necessary for a TARDIS to make a trip through time is many orders of magnitude more then that of a star.

Due to their genetic structure, all Time Lords possess at least a quantum of Artron Energy. During Vortex travel the DNA of crewmembers will be lightly irradiated with Artron Energy from the universe's background radiation. For this reason traveling in a TARDIS has significant effects on the brain of any lesser species. The radiation incrementally increases the amount of artron energy they possess. Aside from providing greater reserves for certain telepathic situations there are no side effects from this irradiation. Although it will continue to accumulate and never fade, it will never reach dangerous levels. These effects will show up very plainly in certain types of very advanced brain scans and the effect can be used to date the exposure.

Since Artron Energy is used by both TARDISes and Gallifreyans, a TARDIS can use its power to help a Time Lord regenerate. However, if a Time Lord's exposure is too great, he must die or regenerate within a day. A Gallifreyan can save an irradiated victim by absorbing the energy from their body into his own. After doing this a regeneration will be necessary to get rid of the excess energy. Artron energy flows in a TARDIS can be disrupted by some types of magnetic field and lead shielding.

The Doctor's TARDIS might be attracted to the Artron Energy produced by the conscious minds of sentient beings collapsing quantum waves into History. That would explain why there is sentient life everywhere she materializes.
