Nicely put. I also do not know of masses that do not have a gravitational field, resp without 'curving' spacetime. And that is an important reason for me not to see a causal relationship between mass and curved spacetime.

Second time I'm unable to contribute.
Eise replied to naitche's topic in Suggestions, Comments and Support
Hi Naitche, I sometimes have such kind of problems too. For me a reload of the web page helps. Maybe you too? Cheers, Eise -
Just as a side note: 'without examination' does not mean necessarily 'wrong'. It means for me that even in the 'hard sciences' there are philosophical assumptions, that even (some?) scientists might not be aware of. I chose this disclaimer because of the disdain that scientists often have of philosophy. Don't be afraid: philosophy is much harder with pseudo science, quasi scientific speculations, free riding ideas with no basis on (observable) reality, or metaphysical fantasies.

Hmm. I don't think naming it a cause, and even a mechanism, is a good way expressing the relationship between mass and spacetime curvature. In my opinion that would mean that physics would be able to describe the mechanism, and that implies new laws of nature. I think that we recognise mass because of its curvature (or inertia). Nobody asks for how a charge 'causes' an electrical field. So why should one do it for a gravitational field, even if we now know that this field is a geometrical curvature of spacetime? So if these are the only two possibilities, I opt for option 1.

Really? Bold by me. If a 'scientific article' cites Deepak Chopra as serious witness, then it is not serious scientific article. Maybe you should read Susan Blackmore: in her student days she had an OBE, and she started a career as 'believing' parapsychologist. But her serious empirical investigations turned her into the end being a sceptic, and leaving the field of parapsychology. I can highly recommend Dying to Live: Science and the Near-death Experience and The Adventures of a Parapsychologist. From the Wikipedia article:

Ah, Descartes 1.1. 'Res extensa: 3 spacial dimensions. 'Res cogitans': mind. Calling it a dimension is just obfuscating method of hiding substance dualism. 'Substance dualism', because something has to exist in this 'dimension', otherwise it is just empty. Nope. To use your metaphor: our mind is a whirlpool in the brain, not in your imaginary dimension.

How do scientists explain RF waves traveling, without a medium?
Eise replied to Capiert's topic in Speculations
Yes. And? If you want to stick to old fashioned meanings then physics is philosophy. Newtons 'Principia' is clearly a work of philosophy: it is even in the complete title. So. Can we just look what is done under the header of 'philosophy' in academia today? Or maybe I do not even understand what you are trying to say. -

Philosophy is not a pseudoscience. Yep. Philosophy is not even science. It is reflection on how we think, being it on the subject of politics, ethics, or ... science. See my disclaimer. -
Curiosity on the relationship between matter and energy
Eise replied to Silverstreak's topic in Relativity
I would say even stronger: it is the factor needed to put space and time on the same footing. So to speak, the 'exchange rate between space and time'. This 'exchange rate' determines the causal structure of spacetime. It leads necessarily to the fact that there must be a maximum speed with which events can be causally related. Particles with mass can never reach this speed, as it would need an infinite source of energy. On the other side, massless particles can only travel at this speed. Thus the speed of light is not 'the speed of light': it is the speed of all massless particles. So the answer is: if the causal structure of your alternative universe is the same as ours, then the same relationship holds. -
Just a side note: not 'centuries'. The latest gospel written was that of John, and historians estimate that it was written around the year 100 CE. I always supposed that Mohammed was much more historical than Jesus. The merchant being his uncle, such stuff. But maybe I have to correct that opinion. And was Mecca not already a place of religious worship: there stands the Kaaba, which is older than Islam. Could that have been a reason to conquer Mecca, to seize power over this important religious symbol?

It depends on the application, if a quantum computer is really faster than traditional digital computers. So if computers with enough qbits can be realised, some kinds of calculation will be much faster. But it is a big 'if'. I am afraid, quantum computers will go the same way as nuclear fusion reactors, unless some stable 'room temperature' realisation of qbits is found. But I expect that those researchers that work on quantum computers will always say that a breakthrough is around the corner, as in nuclear fusion. But that is just my gut feeling, reading about the progress being made with both technologies.

Guided evolution (split from Evolution not limited to life on earth?)
Eise replied to Luc Turpin's topic in Speculations
Strawman alert! If you are arguing against evolution, then argue against what evolution theory really says, not your uninformed interpretation of it. -
What are the benefits of understanding our free will?
Eise replied to dimreepr's topic in General Philosophy
Nope. I tried to bend the discussion in that direction, finding the most useful definition, but it seems everyone wants to stick to their definition. I think this is the main problem when discussing free will: people first decide if we have free will or not, and then rationalise their viewpoint. I gave it a try in the other free will thread: But it did not help. I have the impression, that nobody ever gave a good argument against the concept of compatibilist free will. All arguments given are against libertarian free will, which for me is like arguing that circles have no angles. The concept of libertarian free will is just as incoherent as a circle with angles. -

Yes. But there is also the opposite: congestion influencing drivers. They get irritated, their cars use more gas, local pressure on the road is increasing where the congestions are, etc. So the congestion, as congestion, has impact on the components it is built off. Maybe an example of @TheVat's down causation? What you are suggesting is e.g. the impact of drugs on the brain. By changing something at a lower level (chemistry) one also changes mental phenomena.
