This may be a dumb question, but could dark matter just be regular matter, like planetoids? What if interstellar space had a light sprinkling of things like Oumuamua?
On an interstellar scale, maybe this could create the lensing effects and explain some other phenomena. Is it unreasonable that 5/6 of the mass of the universe is like the stuff that makes up planets, but isn't lit up as brightly as a star?
- dTal 8y agoNot a dumb question, but obviously they've thought of that: https://en.wikipedia.org/wiki/Dark_matter#Baryonic_matter https://en.wikipedia.org/wiki/Dark_matter#Baryonic_matter
- InclinedPlane 8y agoThis is the "MACHO" (massive compact halo objects) theory, which has been tested and disproven. The missing mass can't be gas or dust clouds because that would have certainly observational traces which we have looked for and don't exist. It can't be planetoids because that would cause a frequency of gravitational micro-lensing of stars in other galaxies that we do not observe.
