Relativistic Jets

This website has been moved to:

A relativistic jet is a jet of plasma that is ejected from some quasars and galaxy centers that have powerful magnetic fields. It is conjectured that the jets are driven by the twisting of magnetic fields in an accretion disk (the plate like cloud of matter) found encircling many celestial objects. In super-massive bodies, immensely strong magnetic fields force plasma from the accretion disk into a jet that shoots away perpendicular to the face of the disk. In some cases, these columns of plasma have been found to extend far enough to refute the idea of a young universe.

For example, the quasar PKS 1127-145 has a relativistic jet exceeding one million light years in length1. Because the speed of light cannot be exceeded by any known form of matter, this column must be at least one million years old.(2)

Russell Humphreys, an American physicist and creationist author, proposed in 1994 that the Earth is located near the center of a finite and bounded universe and that the entire universe expanded out of a "white hole" (the reverse of a black hole). He invokes relativistic time dilation to explain how billions of years elapsed in the distant universe while only a few days or weeks passed on Earth. Light from distant galaxies billions of light years away reaches Earth for a relatively short history of less than 10,000 years. Humphreys also claimed that his model explains cosmological redshifts and the cosmic microwave background radiation34.

Humphreys' proposal grows out of the addition of three assumptions to Einstein's equations:56
1. The universe has expanded from a previously denser state
2. The universe is bounded in space
3. The earth is located at or near the center of the universe(7)

John Hartnett has recently developed a new creationist cosmology which he claimed to be superior to Humphreys' "white hole cosmology". Hartnett's model incorporates a concept of "cosmological relativity" and a 5-dimension universe89. Similar to Humphreys, Hartnett invokes time dilation to solve the starlight problem.

The concept of c-decay, the slowing of the speed of light, was first proposed by Barry Setterfield in 1981 in an article for the Australian creationist magazine, Ex Nihilo. He selected a number of historical measurements of c starting with the original measurement by Ole Rømer in 1667, and proceeding through a series of more recent experiments, culminating in "modern" measures in the 1960s. These showed a decreasing speed over time, which Setterfield claimed was in fact an exponential decay series that implied an infinite speed in the not distant past11. The claim was later expanded to cover an apparent similar decay of several other physical constants12. Setterfield argues that this resolves the so-called "starlight problem".

As Setterfield's original suggestion in Ex Nihilo notes, "If you propose that the universe and all in it is the product of an act of creation only 6-7000 years ago, many people ask - 'How is it that objects millions of light years away can be seen? Surely such light would take millions of years to reach us." If c is a constant, as is widely accepted, then this implies the universe is billions of years old because we can see objects billions of light years away. However, if the speed was significantly faster in the past, as Setterfield argues, then the light would have traveled most of this distance in a short time. Setterfield proposes this as an alternative to mainstream physical cosmology and, as such, c-decay represents a unique creationist cosmology13.(14)

Theoretical problems abound with the idea that the velocity of light might be changing with time. Einstein's famous theory of general relativity is the most serious challenge. To remind you, the theory is reproduced here: [E = mc2, where E = energy, m = mass, and c = velocity of light]

Although still called a "theory", Einstein's equation has survived the tests of nearly a century of observational confirmation. The equation above shows that any change in the velocity of light results in huge changes in either the amount of energy or mass in the universe. For example, a modest 2-fold decrease in the velocity of light would result in a 4-fold decrease in the amount of matter, or amount of energy in the universe. There is no evidence that any of these kind of changes are occurring in our universe.(15)
