Conceptual Starting Point

The Shuttle and Missile Objection reveals what I argue is a logical inconsistency in special relativity whenever physical existence is attributed to distant events through the relativity of simultaneity.

Conceptual Consequences

This thought experiment leads to three major conclusions:

1. Simultaneity cannot be purely relative at the physical level.

2. A universal present is required to preserve the coherence of the physical world.

3. The one-way speed of light cannot remain physically invariant under every spatial configuration.

Experiment 1 — Interferometric Test

Place a compact interferometer aboard a spacecraft in order to determine whether interference patterns depend on the spacecraft's motion relative to a given spatial configuration.

According to the conclusions of The Shuttle and Missile Objection , the spacecraft differs fundamentally from the Earth because of its mass. Length contraction must therefore be interpreted within a relational framework distinct from both Einstein's and Lorentz's approaches.

Experiment 2 — Doppler and Clock Analysis

Use Doppler measurements together with ultra-precise optical or radio clocks to determine whether variations in proper time depend on motion relative to the surrounding spatial configuration.

Unlike the standard interpretation of the twin paradox, this approach investigates whether time dilation depends on a real spatial structure rather than solely on relative velocity.

Scientific Perspective

If such a dependence were experimentally demonstrated, it would provide evidence in favour of a relational structure of space-time and would motivate a reconsideration of the physical interpretation of simultaneity, motion and the invariance of the speed of light.
