Astronomy and Cosmology

1st off i watched this about space and the scientist came to the conclusion that at the Center of EVERY Galaxy is a Super Massive Blackhole that has 3 billion times the mass of the sun how can they say that about every galaxy and i thought blackholes had infite mass, density and infinite gravity??......... 2nd. Stellar Blackholes rip u apart before u actually reach the inside and with Super Massive blackholes u reach the inside but once u do u get incinerated by the stars and other matter swirling around in it....... what makes scientist come to these conclusions? is it proven? 3rd. once u cross the event horizon not even light can escape what can …

Hubble only noticed 1/4 of what the Universe (Cosmos) is doing when he said it was Expanding (E/).

The idea that the universe might be a simulation run in somebody Else's computer has got into the the Noo Yo'k Tahms----the SCIENCE section, not Entertainment. http://www.math.columbia.edu/~woit/wordpress/?p=586 there is Templeton money behind it. the author of the Times piece is at a Templeton funded dream-tank called Future of Humanity Institute and he is attacking Peter Woit for being skeptical of the idea that we are in Matrix. So Peter Woit, in the firm belief that his blog is being read by the Overlords has sent a message to them begging them not to turn us off. the blog post I linked to here has further links to the NYT article and the house-blog …

The question I would like to pose and is, does a source of gravity have an effective or practical range within our current expanding universe? Here is my logic. If gravity implies GR, GR will cause a contraction in space-time that decays with distance from the object. The universe is also in motion, with many objects moving at relativistics speeds. This SR will also create pertubations in space-time. As such, when the effect of gravity gets really low, at long distances, background SR should create space-time noise that will make the affect of weak/distant gravity become indeterminant. In a static universe this would not be the case. But in a dynamic universe we have a ve…

The current understanding is that the core of older stars is composed of iron since this is the final exothermic atom to form and is heavier than all the lighter atoms. This has a conceptual problem that needs to be investigated. It has to do with the definition of density, with is mass/volume. At the temperatures of the core, will the iron be totally ionized? If it still retains even one electron in a stable orbital configuration its volume will increase, thereby lowering its density by many orders of magnitude. It will become a walnut in a football field. It will only take 55-60 hydrogen peas in the same football field to exhibit the same or higher density. Here i…

As in can you travel downwards. If you can what is downwards and if you cant what happens if you get in your spaceship and go downwards. Is there like planets and suns below us?

As much as I want to laugh about what a friend in college was explaiing to me I couldn't because his question was relativly to me unanswerale. "Why should the laws of physics apply to something that we can't understand ourselves such as the black hole?" "In many ways the black hole seems like a rip in the fabric of space." "I would think that a rip in space would create equal or even more of a pull from gravity than a black hole." "Why haven't scientist even considered the fact that there worm hole is right in there face?" I wanted to laugh but at the same time i had no explanation to any of his questions except the fact I agree that physics should not apply…

During a recent lecture, my professor discussed the incident during which the astronauts aboard the Atlantis space shuttle reported seeing strange symbols in the haze and storm clouds that prevented them from landing for nearly three days. After the lecture, I took copies of the images, reversed the colors & discovered something amazing! The shapes of the images nearly precisely resemble shapes found in Baphomet lore.

it is frightening to see the comparison with the sun. Click here to see it. If we crash to the sun, who would tell that we really lived?!

Ok, so I guess I'm stupid because I had always thought those beautiful, awesome pictures of nebulas and such were actual colors. Now I'm learning that much of this color is added to distinguish the various ingredients - like hydrogen and sulfur. So, now I'm wondering, what do these things really look like to us? If I'm traveling in the starship enterprise and happen upon the Eagle Nebula, what would it look like to me?

Check out Spitzer's newest press release: Here's the rest: http://www.spitzer.caltech.edu/Media/releases/ssc2007-13/release.shtml its really amazing to think of just how MASSIVE this stuff is...

Hi everyone, I was reading about a new exoplanet that has been discovered by the Transatlantic Exoplanet Survey, http://www.unregisterednews.com/content/view/198/51. Does anyone have any idea about how such a huge planet could form so close to a star? It completes one orbit in 3 1/2 days! What kind of a star is GSC02620-00648, anyone know how this might affect planet formation?

just been found, and hasn`t really hit the net yet, it`s roughly 70% larger than Jupiter. the only ref so far is: http://news.bbc.co.uk/2/hi/science/nature/6934603.stm

As I look here, I notice the first criteria for planethood was that it must orbit the Sun directly. Does that mean that all objects outside our solar system, which, technically, do not orbit the Sun, are automatically not planets? Just goes to show how non-credible Wikipedia is.

Check out what Spitzer had just released: For the rest see http://www.spitzer.caltech.edu/Media/releases/ssc2007-12/release.shtml Cool huh? do you think that many planets have water?

One of the most important talks at Loops 07 last month. doesnt need to put in einstein-hilbert action, gets it out as a prediction see page 12 background independent, page 12 gets inflation in early universe without inflaton (no fine tune, no exotics) page 16 gets scale invariant fluctuations in largescale structure as observed in CMB for free without fine tune, see page 28 REUTER. he has a minimalist direct quantization of Gen Rel no extra dimensions, no exra NOTHING where we used to think it was non-renormalizable and where Weinberg TRIED to prove it was asymptotically safe but failed in 4D case, Reuter has succeeded in showing asymptotic safety …

The other day my Astronomy teacher made a very valid point in his lecture. He pointed out how big the world is compared to Humans, and vast of a wide range it is. And less than .05 percent of the population get to see the whole world. He then talked about how small the earth is compared to our galaxy, after all we can only reach the moon. Then he told us to imagine how big the galaxy really was, we have barely made it off earth. And again to the human race earth is a huge thing. But then he said that there are hundreds, Thousands, Most likely Millions of other Galaxy's Making up the universe. The size of the universe could very possibly have no end, This is hard for us to…

This is the way I understand new growth of the universe. Matter congregates into dense enough patches that they start reacting together until it gets dense enough to start a fusion process. However, this doesn't seem to make sense out on the fringe, since logically, the fringe should be the least filled with matter. Since matter should be so sparse out on the fringes, then the chances of matter congregating in dense enough patches out on the fringe in order to promote star building should be infinitely small. What is the explanation of this paradox? Unless it is dark matter that accumulates, rendering the Big Bang Theory a myth, or at least as we know it.

The moon's orbital around the earth is getting larger and larger. Why does this happen?

Was Einstein right or wrong in saying: "If you can't explain it to your grandmother, you don't understand it"? "No space empty of field". 'Wavicles' = gravy over potatos or potatos under gravy: the ambivalence of particle and wave theory. The non-mathematical translation and reinstatement of Einstein's presently abandoned Unified Field Theory (The math is already done). The gravitational effects of the expansion of 4-D physical matter with 5 & 6-D space. Einstein's so called 'biggest blunder' was right after all. Mr. Mark McCutcheon's gravitational party is 47 years tardy. Electromagnetic resolution of quantum mechanics & field theory. Atonement of continuity with…

Do we know of any solar systems that have planets which orbit in opposite directions but maintain the same plane? Any solar systems with planets orbiting in different planes? Do we know of any stars orbiting a galactic core in the opposite direction as the majority of stars? Do we know of any planets with moon systems where any of those moons orbit in opposite directions to each other, or in different planes? Thanks for any help on this.

1. Where is the sun in its ecliptic when it is the hottest period in the northen hemisphere? 2. Take a look at the picture I upoloaded. Why is the time that the sun is at the meridian again 12:30 rather at at noon? How do you explain the wave shape of the curve? I'd think that it's because the discrepancies between the sidereal day and the apparent solar day, I don't know if it is the answer

Hi The high redshift supernovao survey came out with a supprising result: the expansion of the universe is accelerating. The first explaination proposed is that there should be an unknowed force that drive that acceleration, and cosmologist called it drak energy. I have an other explaination using only relativity. Let me exposed the principles and observations on withch I base my reasonning. 1- Time slowing down in a gravity well. This is experimentally verified by many method. One of it involve and radiation emiter situated above a detector: the radiation is blue shifted. 2- The large scale structure of the universe is like a foam: a web of galaxies and galaxy clust…

Dear Friends First of all ,I would like to thank you for your interest and time. Please ,I would be very grateful if you send our message here to all our members in all Forums,Universities and asking some scientists to share me to publish some series books in Universe,Astrophysi cs,NewTheories of dimentions and Strings. I am asking Prof.KAKU from USA,and Prof.Hawking from U.K for this matter. I would appreciate it if you would please pass my deeply greetings along to all astro scientists who look towards to share us with this global works. With sincere gratitude and all the love we have.

when we talk about a black hole as being infinitely dense, is that not a figure of speech for "very very dense more than any other object we know of yet?" if it was really TRULY infinitely dense, would not the event horizon match the outer boundaries of the universe?
