The Event Horizon Telescope (EHT) has resolved the event horizon of a supermassive black hole

On April 10th the globally coordinated announcement was made of the first ever image of the event horizon of the supermassive black hole at the centre of the distant galaxy Messier 87 (M87). The galaxy is at a distance of 55 million light-years and the supermassive black hole was confirmed to have a mass of 6.5 billion suns. See details of press release here.

The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of supermassive black holes at the centre of galaxies.

This is the work of many astronomers using millimetre wave VLBI radio-telescopes across the planet. By stitching together the power of 8 state-of-the-art mmWave radio-telescopes they essentially turned the planet into one giant radio-telescope. By using such a large telescope and millimetre wavelengths they gained never before obtained resolution to image the event horizon, which is about the diameter of our solar system.

Nearly redundant baselines are overlaying each other, i.e., to ALMA/APEX and SMA/JCMT. Such redundancy allows improvement in determining the amplitude calibration of the array.

The results, so far, are consistent with all predictions of Einstein’s General Relativity theory.

From the biblical creationist perspective this is, yet again, good operational science. There is nothing new here that refutes the biblical timeline of about 6 thousand year because that is subject to historical science considerations. It is not an operational science question.

The distance to the galaxy is about 55 million light-years. Using the Einstein Synchrony Convention (ESC) (which assumes isotropic speed of light, c) the millimetre waves used in this measurement took 55 million years to reach Earth. But using the Anisotropic Synchrony Convention (ASC), where the incoming speed of light, one-way, is chosen at infinity, the black hole is essentially observed in real time. No delay. This is consistent with the biblical description of events in the cosmos. See Genesis 1:16-19, Psalm 33:9, and Isaiah 48:7,13.

The data was taken from the different telescopes and was assembled and processed over a period of about a year but those initial observations were taken over a period of 7 days in April of 2017. Assuming the ASC, over those days the supermassive black hole was “observed” in real time. In the same way over the 24-hour period Day 4 of Creation Week about 6000 years ago all the stars and galaxies (with black holes at their centres) were “observed” at the earth as God created them in real time (Genesis 1:16-19). God spoke and “it was so.”
