Trace fossils provide us with indirect evidence of life in the past, such as the footprints, tracks, burrows, borings, and feces left behind by animals, rather than the preserved remains of the body of the actual animal itself. Unlike most other fossils, which are produced only after the death of the organism concerned, trace fossils provide us ...
While the radial velocity method provides information about a planet's mass, the photometric method can determine the planet's radius. If a planet crosses in front of its parent star's disk, then the observed visual brightness of the star drops by a small amount, depending on the relative sizes of the star and the planet. [6]
Many successful criminal prosecutions rely largely or entirely on circumstantial evidence, and civil charges are frequently based on circumstantial or indirect evidence. The common metaphor for the strongest possible evidence in any case—the "smoking gun"—is an example of proof based on circumstantial evidence. [5]
While there is indirect evidence for Christian communities in Gaul and Upper Germania, like the persecution of Christians in Lugdunum (modern Lyon) in 177, [18] [22] [d] the first reliable evidence of Christianity north of the Alps until now was a mention of Maternus, bishop of Cologne, who participated in the Synod of Rome in 313. [19] [15] [e]
Instead, researchers might find indirect evidence, such as climate changes, anomalies in sediment, or traces of nuclear waste. The hypothesis also speculates that artifacts from past civilizations could be found on the Moon and Mars, where erosion and tectonic activity are less likely to erase evidence. The concept of pre-human civilizations ...
Indirect detection experiments search for the products of the self-annihilation or decay of dark matter particles in outer space. For example, in regions of high dark matter density (e.g., the centre of the Milky Way) two dark matter particles could annihilate to produce gamma rays or Standard Model particle–antiparticle pairs.

ISIS terrorist Shamsud-Din Jabbar was captured in new images strolling around New Orleans a little over an hour before he rammed a pickup truck into a crowd celebrating the New Year on Bourbon ...
In an approach known as multi-messenger astronomy, gravitational wave data is combined with data from other wavelengths to get a more complete picture of astrophysical phenomena. Gravitational wave astronomy helps understand the early universe , test theories of gravity , and reveal the distribution of dark matter and dark energy .
