Can radio astronomy apply “red shift” to statistically determine their relative movements from our position?
- phire 6y agoYou can only apply red shift calculations if you know what frequency it should be. We have no idea what they are so even less clues about what frequency it should be. It works for regular stars because each element emits light peaks at predictable wavelengths which we can measure and calibrate on earth.
- patagonia 6y agoSince they’re all expected to be emitting at roughly the same frequency (or at least we could assume for testing purposes) couldn’t we throw all their data into some maths to compare?
