新研究将水星收缩估计精确至2.7至5.6公里

"...groundbreaking..."

"...shed new light on the long-standing question..."

"...novel method..."

"...more accurate understanding..."

"...similar to how baked goods shrink as they cool..."

"...evidenced by the deep cracks—thrust faults—on its surface..."

"...leading to the uplifts of its rocky surface..."

"...offers a narrower range..."

"...suggesting that the planet’s radius has shrunk by about 2.7 to 5.6 kilometers..."

"...addresses this issue..."

"...allows for a more consistent and reliable measurement..."

"...key innovation..."

"...higher degree of accuracy..."

"...revealed that, no matter which dataset they used..."

"...new methodology offers a clearer and more consistent understanding..."

"...massive fault..."

"...may have formed as the planet contracted while cooling..."

"...fundamental part of the planet’s geological evolution..."

"...comparable to the cracks that form in baked goods..."

"...not random but rather occur in a manner that accommodates the ongoing shrinkage..."

"...gain valuable insight..."

"...serve as a geological record..."

"...offering clues about its internal processes..."

"...crucial for understanding the planet’s thermal history..."

"...better model the cooling of its core and its internal heat flow..."

"...paint a picture of how Mercury, a planet with no atmosphere and extreme temperature variations, has evolved..."

"...refine the estimates..."

"...paves the way for more detailed and accurate models..."
