Exploring The Plasma Universe

[Tammy]

Speaker: Melanie Windridge.

Plasma is sometimes called "the fourth state of matter" as it is a special, energised state where the atoms of a gas are stripped of their electrons. This soup of charged particles (the negative electrons and the positively charged atomic left-overs, called ions) behaves in strange and beautiful ways. Sometimes the electrons can reattach themselves to the atoms and emit light in this process, so plasmas give off a huge range of electromagnetic radiation. They also conduct electricity and respond to electric and magnetic fields, creating filaments and structures.

Plasma makes up 99.999% of the visible universe, most of this in space such as the Sun and stars, the solar wind and galactic nuclei. On Earth, we are familiar with plasmas as lightning, the aurorae, plasma TVs and neon lights. This talk will take you on a journey through space to the solar system and, finally, to Earth, exploring the beautiful and fascinating plasmas of the universe, and the numerous and varied applications of our increasing knowledge of plasma.

Biography.

Melanie is a plasma physicist with a PhD from Imperial College London, where she researched fusion energy in partnership with Culham Centre for Fusion Energy, Oxfordshire. In 2010 she toured the UK as the Institute of Physics Schools Lecturer, talking to over ten thousand teenagers about fusion. She has made numerous television and radio appearances, including BBC's Bang Goes the Theory, Country Tracks and My Genius Idea and National Geographic Channel's Madlabs.

A Plasma Universe ?

The plasma universe is currently enjoying success as a "Big-Bang basher." In due course, its own weaknesses will begin receiving more attention. The lesson is clear: Creationists should be especially cautious about accommodating new science ideas, even if they oppose evolutionary models like the Big Bang. The replacement may be even worse than the original problem! Steady State, Big Bang, Plasma — naturalistic theories of origins will continue to rise and fall.

Further, the current crisis of theistic evolution in defending the Big Bang shows the embarrassing result of compromise. Those who have wrongly inserted the Big Bang into Genesis may someday be the only ones left to defend the idea of an initial explosion! The creation of the universe was supernatural, by definition, and will always remain beyond the understanding of skeptical cosmologists. This is not to say that the creation view closes the door to inquiry. Instead, it accepts the refreshing and truthful fact that there are limits to the domain of natural science.

As matters stand at present, there is no better astronomic theory for the origin of the universe than the inspired explanation of Scripture. "By the word of the LORD were the heavens made; and all the host of them by the breath of His mouth. . . . For He spake, and it was done; He commanded, and it stood fast" (Psalm 33:6,9). ". . . for He commanded, and they were created" (Psalm 148:5).
