Comets: Heavenly Signs, Timekeepers, and Echoes of Creation’s Order

(This discussion introduces a theory developed by Dr. Wright. This will be presented in several installments and will be an ongoing discussion,)

Unlike meteorites, which are primarily rocky or metallic fragments, comets are composed largely of dust, ice, and volatile compounds. They were created as part of the original solar system on Day 4 (Genesis 1:14-19) alongside the planets and Rahab. Comets serve as signs in the heavens, and their predictable, repeating orbits allow them to function as natural markers of the passage of time. Because comets lose mass each time they pass close to the Sun through sublimation and outgassing, their existence provides strong evidence that the solar system cannot be billions of years old. If they were that ancient, they would have long ago evaporated or disintegrated completely. Comets are not associated with the destruction of Rahab and represent a separate class of created bodies that have remained relatively stable since creation. Their ability to remain visible in the sky for many days or weeks during each passage has allowed them to mark significant events and signs throughout history, both in biblical accounts and in the broader record of humanity. They continue to serve as potential prophetic signs for events yet to come (Luke 21:25; Revelation 8:10-11).

Several biblical events can plausibly be linked to comets within the Rahab framework. These connections highlight how God uses the stable, repeating nature of comets as visible signs that align with His sovereign purposes.

The Star of Bethlehem that guided the Magi (Matthew 2:1-12) is one of the clearest examples. The Magi described a star that appeared in the east, moved, and stood still over the place where the child Jesus was. A bright comet visible for weeks or months would fit this description perfectly. Unlike a fixed star or planetary conjunction, a comet can appear to move relative to the background stars and remain visible long enough to guide travelers over great distances. In the Rahab model, such a comet would have been one of the original Day 4 creations, timed by God to announce the birth of the Messiah.

The prophetic descriptions of “falling stars” or stars falling from heaven (Matthew 24:29; Mark 13:25; Revelation 6:13) align closely with meteor showers produced by comets. Periodic comets leave streams of debris in their orbits. When Earth passes through these streams, the result is a shower of meteors that appear as stars falling from the sky. These events serve as signs of coming judgment and cosmic upheaval, exactly as described in end-times prophecy. Because comets return on predictable cycles, their associated meteor showers function as recurring reminders of God’s control over the heavens.

The trumpet judgments in Revelation also contain comet-like imagery. Revelation 8:10-11 describes a great star named Wormwood falling from heaven, burning like a lamp, and poisoning a third of the rivers and springs. This passage has sparked debate over whether Wormwood is best understood as a comet or as a meteor fragment from the Rahab remnant belt. On the comet side, the description of something burning like a lamp and remaining visible long enough to affect widespread waters fits the prolonged appearance of a bright comet or its fragment. Comets release toxic gases and dust as they approach the Sun, which could easily poison rivers and springs with bitter, harmful compounds. On the Rahab meteor fragment side, a large carbonaceous chondrite or stony meteoroid from the asteroid belt could airburst or impact with similar fiery effects and release sulfur-rich or metallic compounds that render water undrinkable. Such a fragment would produce an intense, sudden fireball and toxic fallout, matching the “falling” language and the immediate poisoning described. Both interpretations are consistent with the Rahab model. A comet would represent one of the stable Day 4 creations used as a sign, while a Rahab fragment would show how God can still employ remnants of the Flood-year cataclysm for later judgments. It would be especially fitting for Wormwood to be a meteor from the Rahab remnant, since the Flood’s judgment itself originated with meteorites from Rahab’s destruction. The parallel is too profound to be coincidence. God sovereignly used meteoritic material to bring global judgment at the Flood and could use a similar instrument for this future, targeted judgment. The exact physical mechanism is secondary to the clear prophetic warning of judgment.

In the Old Testament, Balaam’s prophecy in Numbers 24:17 foretells “a star shall come out of Jacob, and a scepter shall rise out of Israel.” While this is ultimately messianic, ancient interpreters and some modern scholars have seen a possible reference to a comet as the visible sign. A bright, tailed comet rising in the sky would have been a striking and memorable heavenly marker, fitting the poetic language of the prophecy. This illustrates how God often speaks simultaneously through symbols, shadows, and stones (real historical events), as has been noted in other writings by Dr. Wright. The star imagery can therefore be symbolic of the coming Messiah without excluding its historic and prophetic dimensions. The same heavenly sign can function as a real astronomical event in the past, a shadow pointing to Christ, and a prophecy of future fulfillment.

These examples demonstrate that comets, as stable Day 4 creations, serve a dual purpose in our model. They are not products of the Flood-year chaos like Rahab fragments, yet they still testify to the effects of the Fall by showing gradual decay and mass loss. At the same time, their predictable visibility allows God to use them as precise signs throughout redemptive history, from the announcement of Christ’s birth to the warnings of future judgment. In this way, comets reinforce the model’s emphasis on God’s sovereign timekeeping. They mark the passage of time, point to key biblical events, and continue to function as heavenly signs that point humanity back to the Creator who upholds all things (Colossians 1:17).
