Wow. Those are grand and ambitious questions. - There are different theories on how physical laws came into being. None have been proven. As far as we know, these physical laws that govern us today are the same laws that have been in existence since the Big Bang. - It is true that we may...

As I understand it, at the surface of a neutron star, most light is emitted in the X-ray range. In the visible range, red is emitted at about the same as blue and the other colors, so it would appear white to human eyes. Your human eyes and body should not orbit too closely, or else tidal...

I might suggest breaking up your questions into separate topics. You are asking approximately 15 questions about stellar life. The proper way to answer your question is to write you a book on the subject. Break up the questions, and it will be easier to solve your riddles. Cheers, --Jake

I'm an alumni - BS in CompSci in '96. Highly recommended school, especially for engineering. Hired right away, and made bank in the dot com boom. My main issue with RPI was too much theory, too little application. I didn't have my own computer, and we used Unix workstations - I barely had...

University faculty, professor, scholar, researcher, planetariums positions. Industries include education, government, space science, nuclear engineering, optics, and photography. Backup plans may include patent office clerk, trolling physicsforums.com, and pole dancing.

This could be due to the moving magnetic fields of the Sun. I've always thought of it as a lot of magnetic 'whips' inside the Sun, bursting out into the corona, and when so many whips come together at that altitude, the temperature rises. Or, when new loops form and collapse, this will raise...

When looking for antimatter, we generally look for the electron vs. positron signature of 511 keV. It is my understanding that quarks are always confined in hadrons, and that they are held together by gluons. My questions: - Can quarks be removed from their confinement so that they may...

And remember, Kepler is just the viewing tool. There are Earth-bound computers that go through the difficult task of reviewing every one of those stars. So while Kepler is working for 3.5 years, it will keep scientists busy for years afterwards.

No one has mentioned atmospheric effects yet. An extremely, extremely large telescope could image the Earth, but atmospheric changes would still keep the image too fuzzy to see individual humans. So, where Nabeshin mentions you get 100 photon per second, you still haven't accounted for...

Now we're getting into something that interests me more. What does happen as the magnetic forces of two black holes approach each other? If the relativistic jets are caused by these great magnetic forces, what fireworks would be created as two jets from two great magnetic forces started to...

Yeah. I think I'm pretty cool too, baywax. So the question is now: When did the first atmospheric planets form? The first atmospheric planets could have formed around the first Population III stars, so that would be t=100 to 300 million years. We haven't found those Pop III stars yet, so...

I agree with Clanoth regarding the "no hair" theorems, but I would like to add another useful item. Black holes generally have accretion disks and polar jets, both which can be observed. From an observational POV, having two accretion disks, two sets of polar jets, two magnetic fields, etc...

As I understand it: t=0.1 seconds - primordial nucleosynthesis of ionized H t=300,000 years - universe cools to 3000K and allows electron capture; H atoms formed t=100 million years to 300 million years - universe cools to 30K; a Population III star allows the triple-alpha process and (CNO...

So, what is the followup project to ARCADE? We've got space observatories for all of the other wavelengths - except radio. We need something chilled down to 2.7K, and I don't think any of the space/VLBI plans have liquid helium. I would expect another balloon experiment to look at another...

Hiya Mike. Define "significant effect on the Earth's ecosystem". Humankind cannot agree on whether global warming is an issue that has a significant effect - heck, we all can't agree on the phrase "significant effect". If dust were to fall from the Moon to the Earth, it would mainly burn...
