Shaula replied to a thread When does a protoscience become a science? in Space/Astronomy Questions and Answers

I thought the generally accepted definition was that it becomes a science once the majority of people in the field are constructing and testing...

Shaula replied to a thread Is Dark Matter Equivocal in Science and Technology

If the are WIMPs then they interact via the weak force. Hence the scintillation detectors work the same way as for neutrinos. The difference is in...

Shaula replied to a thread Is Dark Matter Equivocal in Science and Technology

No problems. The size of the available parameter space is only large if you cherry pick what kinds of observations you will accept. But I'm not...

Shaula replied to a thread Is Dark Matter Equivocal in Science and Technology

It is easiest to spot from orbit because the main features we look for (associated with electronic excitations) are in the UV. These are blocked by...

grapes replied to a thread Question about Earth tides in Science and Technology

Those earthquakes are huge, but not large enough to explain the change in earth's rotation. But, the rotation has changed a lot, that's the activity...

grapes replied to a thread Question about Earth tides in Science and Technology

Yes, in the long run. Pretty much the reason for leap seconds--the defining of the day as of a length from a century before meant that we would...

Shaula replied to a thread Is Dark Matter Equivocal in Science and Technology

I don't doubt that there is material there, however the consensus seems to be that there isn't enough based on observational evidence. Yes, you can...

Shaula replied to a thread Is mass a thing? Or is it just a function of how much spacetime something warps? in Space/Astronomy Questions and Answers

Gravity is tied to the stress energy momentum tensor. Mass is only a part of what is responsible for gravitational effects.
