THE VAULT DOCUMENT
Physical Evidence
Physical evidence refers to tangible objects, materials or measurable environmental changes presented as documentation of an event, phenomenon, investigation or claim.
Within The Vault, physical evidence is considered one of the most important forms of evidence because it involves material objects or measurable conditions that can potentially be examined, tested and independently analysed.
Physical evidence may include:
- Objects allegedly connected to unusual events.
- Physical traces left at a location.
- Material samples.
- Environmental changes.
- Artefacts.
- Scientific measurements.
However, the existence of a physical object or measurement does not automatically confirm the explanation associated with it.
A physical item demonstrates that something exists or occurred. Determining its origin, cause or significance requires further investigation.
Role of physical evidence
Physical evidence may be used to document:
- A physical object connected to a case.
- Changes within an environment.
- Material traces from an event.
- Scientific measurements.
- Experimental results.
- Historical artefacts.
Examples include:
- Alleged cryptid remains.
- Objects claimed to be associated with hauntings.
- Unusual geological samples.
- Physical traces at investigation sites.
- Instrument readings.
- Historical artefacts.
Physical evidence is generally considered stronger when it can be independently examined and tested.
Evaluating physical evidence
Physical evidence should be assessed using several factors.
Provenance
The history of an object or sample is essential.
Consider:
- Where did it originate?
- Who discovered it?
- Who has handled it?
- Has it been stored securely?
- Is there a documented chain of custody?
Evidence without a reliable history is more difficult to evaluate.
Authenticity
Physical evidence should be examined for:
- Whether it is genuine.
- Whether it has been altered.
- Whether it has been misidentified.
- Whether it could have a conventional origin.
A genuine object may still have an incorrect interpretation attached to it.
Examination and testing
Where possible, physical evidence should be subject to:
- Independent examination.
- Laboratory testing.
- Scientific analysis.
- Replication.
- Peer review.
The reliability of conclusions depends on the quality of the methods used.
Documentation
Important documentation includes:
- Photographs.
- Measurements.
- Collection records.
- Test results.
- Investigation reports.
- Expert analysis.
Poor documentation can reduce the value of physical evidence.
Types of physical evidence
Objects and artefacts
Objects may be presented as evidence connected to a claim.
Examples include:
- Alleged paranormal objects.
- Historical items.
- Unusual artefacts.
- Claimed biological remains.
Evaluation should consider:
- Age.
- Origin.
- Ownership history.
- Previous examination.
Biological evidence
Biological evidence may include:
- Hair samples.
- Footprints.
- Tissue samples.
- Remains.
- Environmental DNA.
Analysis may include:
- DNA testing.
- Microscopic examination.
- Species identification.
Biological evidence requires careful handling to prevent contamination.
Environmental evidence
Environmental evidence refers to measurable conditions within a location.
Examples include:
- Temperature changes.
- Electromagnetic readings.
- Radiation measurements.
- Air quality.
- Geological features.
Environmental measurements require appropriate equipment, controls and interpretation.
Experimental evidence
Some investigations attempt to recreate or test reported events.
Examples include:
- Controlled experiments.
- Equipment testing.
- Replication attempts.
Experimental evidence is strongest when methods are transparent and repeatable.
Physical evidence in paranormal investigations
Paranormal investigations may collect or record alleged physical evidence including:
- Objects moving without explanation.
- Unusual environmental readings.
- Physical marks or traces.
- Material samples.
Such evidence should be assessed carefully because many reported effects may have conventional explanations.
Examples include:
- Equipment error.
- Environmental factors.
- Human activity.
- Natural causes.
- Misidentification.
Common explanations for physical evidence
Potential explanations may include:
- Natural processes.
- Human activity.
- Equipment malfunction.
- Contamination.
- Misidentification.
- Fraud or hoax.
- Incorrect interpretation.
Considering alternative explanations is a key part of evidence assessment.
Physical evidence and scientific testing
Scientific testing can help determine:
- What an object is.
- What material it contains.
- How it was created.
- Whether it is consistent with a proposed explanation.
Testing may confirm the existence or properties of evidence without confirming a particular interpretation.
Example:
Finding:
"A sample contains unknown biological material."
Interpretation:
"The material comes from an unknown creature."
The second conclusion requires additional evidence.
Famous examples of physical evidence
Some cases involving physical evidence have become significant within mystery research.
Examples include:
- Patterson–Gimlin Film — associated with alleged Bigfoot evidence.
- Piltdown Man — historical example of fraudulent physical evidence.
- Cottingley Fairies — photographs later linked to constructed physical objects.
Each case demonstrates the importance of authentication and critical analysis.
Limitations of physical evidence
Physical evidence has limitations.
These include:
- Objects may be genuine but misunderstood.
- Samples may become contaminated.
- Measurements may be affected by equipment limitations.
- Evidence may lack documentation.
- Results may be interpreted differently.
The existence of physical evidence does not automatically establish the cause behind it.
Physical evidence and evidence ratings
Within The Vault, physical evidence is assessed alongside other available information.
Factors include:
- Provenance.
- Authenticity.
- Documentation.
- Testing.
- Independent verification.
- Alternative explanations.
- Reproducibility.
Physical evidence that can be independently examined and verified generally carries greater evidential value.

Writing guidelines
When describing physical evidence, articles should separate the object or measurement from interpretations.
Preferred:
"The object has been presented as possible evidence connected to the case."
Avoid:
"The object proves the claim."
Preferred:
"Testing identified the material as consistent with a known substance."
Avoid:
"Testing confirmed the paranormal explanation."
unless supported by reliable evidence.
