the claim

The vacuum of space prevents heat conduction.

SUPPORTED

Recorded sources
6 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the vacuum of space prevents heat conduction?

Yes. Multiple reference sources state that a vacuum prevents heat transfer by conduction (and convection), leaving radiation as the mechanism that carries heat through empty space. One fact-check similarly rejects the idea that molecules are required for all heat transfer.

Verdict: SUPPORTED · 6 sources for, 0 against · Last checked

The private library was unavailable for some searches in this check. Missing library results are not evidence against the claim.
