Jason Lisles defends his ASC against Gravity Waves


A blogger asked Jason Lisles about Gravity Waves. He though that, “if gravitational waves travel at the speed of light, and the waves were detected at different moments by two separate observatories, wouldn’t we expect both laboratories to detect the waves simultaneously?

Lisles responded ,(his) response was technical, but he elaborated, explaining that the difference in recordings made by the two observatories in both Washington and Louisiana are a combination of two affects under the ASC. To begin with, the clocks at the two locations use Einstein’s synchrony convention, presupposing the one-way speed of light is identical in every direction. But under the ASC, the two clocks aren’t in sync; they’re off by a fraction. That means we’d expect there to be a small difference in detection time, even if the gravity waves arrived at the same moment.”

Heres an evaluation of this response:

There are several errors in the text, both conceptual and factual:

  1. Einstein Synchrony Convention (ESC): The text incorrectly states that clocks under ESC "presuppose the one-way speed of light is identical in every direction." In reality, ESC does not make any assumptions about the one-way speed of light. It only synchronizes clocks based on the round-trip speed of light. The Anisotropic Synchrony Convention (ASC) is the model that posits a different one-way speed of light in different directions.

  2. Simultaneity: The text implies that if gravity waves travel at the speed of light, they should be detected simultaneously at two different observatories. This is not true, even in the ESC model. If the source of the gravitational waves is not equidistant from the two observatories, there will be a time difference in detection simply due to the different distances the waves have to travel.

  3. Outgoing Gravity Waves: The statement that "outgoing gravity waves would travel slower" under the ASC is incorrect. There is no theoretical basis in either the ASC or ESC models that would suggest a difference in the speed of gravity waves depending on their direction relative to an observer.

  4. Mathematical Predictions: The claim that "the math works out to make the same prediction in time difference under both the ASC and ESC" is inaccurate. While both models can be used to explain the time difference observed in the detection of gravitational waves, the specific calculations and underlying assumptions would be different.

  5. LIGO Observations: The text refers to two observatories in Washington and Louisiana, which are the LIGO detectors. LIGO has observed gravitational waves and the time difference in their detection at the two detectors was used to triangulate the direction of the source. This time difference is consistent with the predictions of general relativity and the assumption that gravitational waves travel at the speed of light

Even if Lisles ASC solution to the gravity waves held with this one recording it would not hold to the 50 other recordings of GW from black hold mergers.

The ASC is firmly disproved.

Distant Starlight and the Anisotropic Synchrony Convention: A Challenge from Neutron Star Mergers

Image
“As these neutron stars spiraled together, they emitted gravitational waves that were detectable for about 100 seconds; when they collided, a flash of light in the form of gamma rays was emitted and seen on Earth about two seconds after the gravitational waves .” The Anisotropic Synchrony Convention (ASC) is a proposed solution to the " distant starlight problem" encountered in young-earth creationism. It was proposed by Dr Jason Lisles of Answers in Genesis. This problem arises from the apparent contradiction between the young earth biblical age of the universe (thousands of years) and the vast distances we observe through telescopes (billions of light-years). The ASC proposes that the speed of light is not constant in all directions, but rather travels instantly towards the observer, explaining how we see light from seemingly young stars. However, recent observations of neutron star mergers present a significant challenge to the ASC.  In 2017, the LIGO and ...

The nebular hypothesis - a challenge to Young Earth Creationism?

Image
Psalms 90 : (written by Moses before Genesis) “ Before the mountains were born Or You gave birth to the earth and the world, Even from everlasting to everlasting, You are God. For a thousand years in Your sight Are like yesterday when it passes by, Or as a watch in the night.” Some recent Young Earth Creationists (YEC) posit that stars were created on Genesis Day 4 of creation as described in the Bible, using the 24-hour day interpretation. This implies that we shouldn't expect to find stars actively forming in the universe today . However, the nebular hypothesis , which proposes that stars and planets form from the gravitational collapse of giant clouds of gas and dust, is fully supported by scientific evidence.  Answers in Genesis (AiG) criticizes the nebular hypothesis over 700 times on their website. Their claims haven't been accepted by the scientific community as well as many many other Christians. On their website an article has the below illustration and...

The accuracy of Radiometric Decay

Image
Radiometric dating is a cornerstone technique used by geologists to determine the age of rocks and fossils. It relies on the predictable decay of radioactive isotopes into daughter products at a constant rate. By measuring the ratio of parent to daughter isotopes in a sample, scientists can calculate its age. Here's a summary of the accuracy of radiometric dating and how some misrepresent it: Accuracy of Radiometric Dating Radiometric dating is a highly accurate and reliable technique, constantly corroborated by various dating methods and geological evidence. Consistency with Half-Life Measurements: Half-life values of radioactive isotopes have been extensively measured in controlled laboratory settings, demonstrating their stability over time. Concordant Results from Different Methods: When multiple radiometric dating methods are applied to the same sample, they often yield consistent age estimates. This reinforces the validity of the technique. Agreement with Geolog...
