Interactive dark matter

Interactive dark matter could explain Milky Way’s missing satellite galaxies

Scientists believe they have found a way to explain why there are not as many galaxies orbiting the Milky Way as expected.

Computer simulations of the formation of our galaxy suggest that there should be many more, smaller galaxies around the Milky Way than are observed through telescopes.

This has thrown doubt on the generally accepted theory of cold dark matter, a substance that scientists predict should allow for more galaxy formation around the Milky Way than is seen.

Now cosmologists and particle physicists at the Institute for Computational Cosmology (ICC) and the Institute for Particle Physics Phenomenology (IPPP), at Durham University, working with colleagues at LAPTh College & University in France, think they have found a potential solution to the problem.

i read the article... which seemed to ask more questions than it answered? It was interesting, although i don't really understand what they are saying.. but it makes me wonder if it will be discovered that distances in space might be illusory and not constantly the same "measurements" . I don't know why i've always thought that there is something to do with measuring the distances in space that is not yet understood. ?¿?

ok, now for some intelligent and knowledgeable responses please.

I agree that it was an article "which seemed to ask more questions than it answered?". The computer simulations don't convince me that a 'theory of everything' has been reached. Not by a long way. It's more sticking plasters on a basically flawed model imo. Why not use the spinning Archimedes screw as a graviton? This simple idea apparently eluded Newton and his contempories. That's where the mistake in physics was made. I've written an ebook on the subject which results in a theory for the Ice Age Carbon Cycle. It's currently been given for editing and publishing.

This from the article,

Scientists believe they have found a way to explain why there are not as many galaxies orbiting the Milky Way as expected.

The answer is they simply do not know and neither does the computer. The universe cannot be 'expected' to be anything other than what it is.

Do not confuse your abject ignorance of science with that of the scientists.

Science may not have all the answers but it does have some ideas as to what the answers might be. That is why computer simulations, like this, are important. It enables the scientists to explore the feasibility of a particular hypothesis, rejecting it if it fails, exploring it further and looking for evidence if it succeeds.

This is the difference between a scientific hypothesis and wild guessing.

The universe cannot be 'expected' to be anything other than what it is.

What a surprise, meaningless drivel. I can only guess that you are trying to look deep. In fact you are just advertising the fact that you have failed to understand the article at the must fundamental level.

You are once again demonstrating your total lack of understanding of what science is.

No one is trying to make the universe anything other than what it is. Science is an attempt to understand how the universe works.

Dark matter is believed to exist because observations support it. Given that it seems to exist scientists are trying to understand its influence. The "missing" satellite galaxies are a problem, it means that the model of dark matter is wrong or incomplete. This hypothesis is an attempt to correct the models so that they fit with the observed universe.

Scientists are not so arrogant as believe the universe is at fault, they know it is their models, their understanding that is the problem. They are also not so arrogant as to continue arguing a case when the evidence has shown them to be wrong. They move on and formulate a new hypothesis. Science is about constantly exploring, constantly learning, constantly admitting when you are wrong and moving on.

Science is NOT about making wild guesses based on absolutely no knowledge and then arguing that everyone else is wrong.

You are right science doesnt have all the answers, it doesnt even have all the questions. Not even close. When i read about science and supercomputers bumbling to reassemble the complete workings of the universe, it reminds me in a lighthearted sort of way of infinite monkey theorem.

My guess (hypothesis) is that the further back in time you look the less likely the mathematics holds up and the less familiar the physics resembles what it is today. That is why the models dont compute. If the function of the universe in the past was vastly different then, how can it ever compute with now? The answer is simple, it never will. And as for the incredibly distant future be prepared to not recognise it at all. Much is still to be learned about the aging of light and how this affects its speed.

What a surprise, meaningless drivel. I can only guess that you are trying to look deep. In fact you are just advertising the fact that you have failed to understand the article at the must fundamental level.

Like i said, the scientists dont know the answer, so what im asking is have they even got the question right to begin with? This is most fundamental to the problem.

You are once again demonstrating your total lack of understanding of what science is.

No one is trying to make the universe anything other than what it is. Science is an attempt to understand how the universe works.

So why do you become so entangled? Is not everyone on earth blown by curiosity? Isnt a scientific nature reserved in all human beings? Its easy for anyone to say what 'science' believes, but im asking you simply, what it is that you believe? Do you have any belief in yourself?

Yes i agree. My guess (hypothesis) is that the answer doesnt lie in dark matter or in the milky way at all. This is howcome the experiment is flawed. Reach further back. Much much further, what was the physics of the beginning that has forced the present to appear how it appears today. How fast did light travel billions of years ago? What was the true nature of our beginnings? We are so far far away from understanding 'reality'.

[Waspie_Dwarf]

At least you are honest enough to admit that you are just guessing. In the past you have denied that. Although trying tom dignify your wild guessing by using the word hypothesis (even if it is within parenthesis) shows that you remain clueless as to how science works and what a hypothesis.

As you have been told repeatedly, guessing has no place in science, therefore I reject your entire post as a worthless waste of words.

runs in and scream.....dark matter is a constellation of dyson spheres....run away fast....

Dont kill me Waspie Dwarf, just another wild guess purely for entertanment reasons...

Dyson spheres would be a cool discovery, sadly they would not explain the behaviour of dark matter.

I'm not in the killing business. Besides there is big difference between humour and being annoying by constantly making stuff up and presenting it as fact in topic after topic.
