The simplest cause of the accelerating expansion of the universe
That’s not consistent with what we know. The universe is expanding, and that expansion is faster as the distance grows. At some distance the space is added at a rate that makes the objects recede faster than c; the light from them can’t get here anymore. If you make claims you need to be able to back them up.

Which is why Larry Flynt noted “Majority rule only works if you're also considering individual rights. Because you can't have five wolves and one sheep voting on what to have for supper” (others have made similar observations over the years) What are the characteristics of this ideal democracy?

What if you are in the minority, and the majority has no interest in such a compromise?

Your thoughts on Neil deGrasse Tyson
He also clearly said at the outset that he was talking about future knowledge - “the day will come” and “I’m imagining a future” and you are just completely ignoring these caveats and end up overstating what he claimed. Do we know of chemicals that make people depressed? Do we know of ones that don’t? Yes. Is this knowledge exhaustive? No! But he’s not claiming that it is.

- Your thoughts on Neil deGrasse Tyson
Except that's not what he said. He said "we're kinda almost there" - which is less bold than what you quoted - and he mentions chemicals causing depression and how some depression is addressed but not cured by antidepressants, but he never makes a statement about its cause in humans. He's not making black-and-white statements. His tone makes it clear that there are still unknowns and things work for only some people. The rest is stating the goal that we hope to reach. How is that not an accurate portrayal? IMO he takes a proper tone in how he presents it.- “Amateur science” and nature apps
One thing I've noticed is that Merlin will let you play the calls and songs of the birds. I played some back and immediately heard the song from the nearby woods. I don't know if it was a response, or if I was just recognizing the song because I could associate it with that species. (it's also made me aware of how much ambient noise there is from car traffic)- Civil war in USA (19th century)
There are different versions of democracy, so having a conflict over which version to implement does not inherently mean you don't have a democratic society.- Colonizing Jovian moons...practical issues of building large structures under the ice
Sure. You could build the pillars I mentioned much deeper, and have a space between the ice walls and any source of heat. You could vent any exhaust through a hole above the settlement. It would be even more like an igloo than a surface settlement. (they could even call the settlements igloos, and come up with some backronym for that) The heat could even help carve out the cave, and you could reach the equilibrium of where the ice stopped melting naturally. You'd have to excavate some of the ice, but some could melt and the runoff fill in any fissures that might exist, making the foundation even more stable. (though ice at that depth is probably pretty solid)- The black hole stars
You should know that there's a lot of things to learn, so perhaps it would be better to ask questions. That would include things like "can you have a star with a mass of a million suns?" and we have some people here who could explain.- Your thoughts on Neil deGrasse Tyson
You can be a scientist but not publish very much; it depends on your circumstances. Not every scientist lives in the "publish or perish" world of academia. In any event, he has a number of journal publications in the last 30 years. here are three from <20 years back The Faint-End Slopes of Galaxy Luminosity Functions in the COSMOS Field C. T. Liu et al., 2008, Astrophysical Journal Letters, v.672, p.198 COSMOS: Hubble Space Telescope Observations N. Scoville et al., 2007, Astrophysical Journal Supplement, v.172, p.38 The Cosmic Evolution Survey (COSMOS): Overview N. Scoville et al., 2007, Astrophysical Journal Supplement, v.172, p.1 I'd like a citation on that "fact" IMO no, but it also depends on the level of discussion. If you aren't supposed to discuss things outside of your area of expertise we'd have to disband SFN. i.e. you can still know certain things and discuss them despite not being an expert. The issue is knowing your limits and recognizing when you are out of your depth. We aren't aware of serotonin and dopamine? That's news to me. Your summary sounds like he was making general statements, which doesn't require expertise. It's wrong in the same sense that all science discussion is wrong - there's always more detail, and general statements always have caveats. But if you object to general statements, you'd have to eliminate almost all discussion.- The simplest cause of the accelerating expansion of the universe
Why would they spiral if not from gravity? At galactic scales you have nothing else to explain accelerated motion. ! Moderator Note Posting to advertise your blog is against the rules, and the rules require that material for discussion be posted here. So none of this "counts" - don't expect that anyone has read it. ! Moderator Note So this is just guesswork. We're not the guesswork forums, we're scienceforums(.net) If you want to speculate, it must be backed by something that's considered science. You need a model and be able to make predictions or compare with existing experiments If you have no math, there's nothing to reference. An idea is just a small part of making a theory. The hard part is making the model (i.e. the math). Credit goes there, not to someone who had a vague notion, and hasn't even checked to see if someone else had (and published) a similar notion in the past hundred years or so. But probably not published, if they had done the math and seen that this doesn't work. And needs a force to explain/account for it.- The simplest cause of the accelerating expansion of the universe
What’s the evidence that galaxies are orbiting the CBH? What are the value of the accelerations in your scenario, and can you show how much mass the CBH must have? The distances involved?- “Amateur science” and nature apps
I was just made aware of a bird call identifier called Merlin. Last evening a friend used some (name unknown to me) app to identify a plant; I used to have one on a previous phone, and newer iOS devices can leverage visual lookup to do so. In the past I’ve used an app to identify insects (bug identifier or picture insect) I also have a sound meter app. What else is out there for nature and science buffs? Preferably free, and stand-alone — nothing that needs to be plugged in to the phone.- Do AI Programs Initiate Discussions to Collect Information?
That would explain some of the activity we’ve seen here- Colonizing Jovian moons...practical issues of building large structures under the ice
Igloos remain stable even with a heat source inside. If the ice/snow is really cold because the ambient temperature is low, and is some distance from the heat source, it won’t melt. A town on a platform would be analogous to this. The pillars would be cold and not melt the ice. The hot air from the town would tend to rise.- My solar panels generation...
This would mean they are selling power to your neighbor at $0.025 per kWh. That doesn’t seem right.- My solar panels generation...
Your neighbors pay the utility $10 for the 100 kWh you generated and the utility delivered. You get $7.50, the utility keeps $2.50.- Hitler's return, World War II, World War III, nuclear warfare, let's save our planet from a great threat
! Moderator Note No. Peddle this crap elsewhere- Testing for Tolerance
Since you have only presented a strawman of the mainstream view, this is moot. Relativity says nothing about “time frames” and copies of the physical universe. That sounds vaguely like the many-worlds interpretation of QM, but one must note that MWI is an interpretation, and not actually QM. Similarly you seem to be offering an interpretation of the prevailing view, which is not the actual science.- Testing for Tolerance
Surely there is some basic premise that’s testable. Every bit of effort you put into telling us how you can’t present your theory is effort you could have put into telling us your theory.- Does carbon capture make sense?
Forest fires are not burning fossil fuels. Forests will grow again, so any CO2 released is offset by growth somewhere. Fossil fuels represent sequestered carbon, stored over many millions of years but released over a much shorter time, and much faster than natural processes could store it again. It is because we were burning fossil fuels that these rates aren’t the same. It didn’t start with the invention of fire - it started with the large-scale burning of sequestered carbon. Most of the time before the industrial era back for hundreds of thousands of years, the CO2 levels were lower than at the outset of the industrial era- Your thoughts on Neil deGrasse Tyson
! Moderator Note Do not, under any circumstances, take it to PM. Just cease and desist with the pot-stirring and stick to the topic under discussion- Testing for Tolerance
As is true for everyone Likewise, we’d like to know your ideas are on solid footing before we waste time learning the subsequent details. e.g. you claim a neutron is an electron magnetically bound to a proton. If that’s a basis for your ideas, I’d like you to justify it. Because if you can’t, i.e. it’s bogus, then anything built on it is bogus as well.- Does carbon capture make sense?
I don’t think this is a zero-sum situation. - Your thoughts on Neil deGrasse Tyson
