Looking at the evolution-ID debate from an engineer's perspective.
“[James G.] Williams [of Caltech’s JPL] reported in 2006 that the distance difference between the Moon’s farthest and closest approach to Earth is increasing nexpectedly by about 0.2 inches (6 millimetres) per year. ...Second, the value of the
“After accounting for changes expected from tidal friction, Williams still has a residual change in the Moon’s orbit that he can’t explain.”
“The tracking data showed that, in 1998, the Pioneer 10 spacecraft was about 36,000 miles (58,000 kilometres) short of what we expected, based on the laws of motion given by Newton and Einstein.. …The final anomaly mentioned deals with “anomalous orbital energy changes of six spacecraft that flew by Earth for gravity assists… These changes do not obey Newton’s law of gravity.” These spacecraft include Galileo, Rosetta, and NEAR Shoemaker. The unexpected speed increases were small (from 1.8 mm/s for Rosetta to 13.5 mm/s for NEAR). At first glance, the data appears to suggest an inverse proportional relationship between magnitude of speed increase and closest approach to Earth (the closer the approach to Earth, the greater the magnitude of speed increase).
“The situation with Pioneer 11 is similar. …we have determined the spacecraft is about 3,700 miles (6,000 km) short of its predicted distance. It is as if something is putting the brakes on both spacecraft by just the right amount that they both change their speed at the same amount in the same interval of time.”
“Since the 1970s, astronomers have known that the outer regions of galaxies appear to violate Newton’s gravity laws. We would expect the stars in a galaxy’s outer regions to travel in elliptical orbits with their orbital speeds decreasing with increasing distance. However, this is not observed. Instead of decreasing, the speeds are essentially constant over a wide region of the galaxy.”The current theory in play to explain the above effect is “that the galaxies actually contain large quantities of unseen material [dark matter] that hold the stars in the galaxy.” Anderson acknowledged that if MOND is correct, dark matter would be superfluous and discarded.
