Dark matter is an elusive substance. Measuring it directly is impossible, and its

existence and distribution can only be inferred based on the influence it exerts on

galaxies and other cosmic objects.

An international team of astronomers and astrophysicists has joined efforts to

create the largest-ever cosmic web map. This has allowed them to visually

represent the distribution of the mysterious substance and to identify the location

of vast cosmic voids. In such low-density regions of the universe, the conventional

laws of physics may not apply.

Calculations indicate that the distribution of dark matter is broadly consistent with

the predictions of the standard cosmological model, which posits that the universe

started with the Big Bang, and then matter expanded and evolved according to

Einstein’s theory of general relativity. However, the scientists did not find a perfect

fit. These unprecedented observations may prompt a revision of one of the great

pillars of physics which describes gravity.

According to the article, where may the conventional law of physics not

apply? Choose the answer that fits best.
