If I understand correctly, there are data/phenomena that aren't explained by current theories. So presumably creating/discovering a better theory (unified theory) would improve our understanding. Perhaps humans aren't smart enough, though. It seems to be the usual assumption that we are, but there doesn't seem to be any particular reason why this assumption is valid. Especially now that we can create "intelligence" that is "smarter" than we are in various ways. We might not be able to make the tools to get the data, and/or we might not be able to understand in any case. Just the idea that "spacetime" is "curved" already seems nearly impossible to follow for probably 99.9% of humans. every day, we benefit from engineers using relativity to adjust satellite based GPS, but i don't think I can really follow these theories.

What is the significance of finding the Grand Unified Theory?
Finding the unified theory might be able to further explain phenomena that aren’t currently understood such as: dark matter, supersymmetric partner particles, antimatter asymmetry and magnetic monopoles³.

Special Relativity:
Satellites in the GPS constellation are orbiting the Earth at high speeds relative to observers on the ground. According to Einstein's theory of special relativity, time dilation occurs when an object is moving at a significant fraction of the speed of light. This means that time passes more slowly for an object in motion relative to a stationary observer. In the case of GPS satellites, their high velocities cause their onboard atomic clocks to tick at a slightly slower rate compared to clocks on Earth's surface.

General Relativity:
In addition to the effects of special relativity, general relativity also comes into play due to the difference in gravitational potential between the satellites and the Earth's surface. According to general relativity, time passes more slowly in stronger gravitational fields. This means that the weaker gravitational field experienced by the satellites in orbit causes their clocks to tick faster than clocks on the Earth's surface.

Combining these two effects, the onboard clocks of the GPS satellites tick at a different rate than clocks on the Earth's surface due to their relative velocities and the weaker gravitational field they experience. If these relativistic effects were not taken into account, the GPS system's accuracy would degrade over time, leading to position errors.

To ensure accurate GPS positioning, the satellite clocks are regularly corrected to match the time as measured by reference clocks on the ground. The GPS system's ground control segment monitors the clocks on the satellites and applies appropriate corrections based on the predicted effects of both special relativity and general relativity. The corrections are then transmitted to GPS receivers, which use this information to adjust for the relativistic effects when calculating positions.
