Beginning Definition and 179 Threads

I am curious. How many people object to a creation [like BB] event? I'm not suggesting this requires a 'creator', merely impossibly complicated circumstances.

Hope everyone had a wonderful Christmas. This time, we have a smaller number of entry, but not lacking in quality. Please vote for the picture that best represents our theme of looking a lot like Christmas. 1. physarrista 2. hypatia 3. binzing...

It's Beginning To Look A Lot Like Christmas This week, you have the freedom to interpret the theme anyway you want. So anything Christmas related qualifies. I would like to take this opportunity to wish everyone Happy Holidays, Merry Christmas, Happy Hanukkah, Happy Kwanza, etc. Zz...

Hello ive been pondering lately about the big bang theory. so far as i know, mislead or not, that all the energy in the universe was derrived from a singularity in nothingness, then decided to at one point break loose and begin to form the universe. i guess my question would be what...

I have graduated with an electrical engineering degree last May, and have been on the job hunt since then. Right now I have three job offers, all of which expire on Monday, and I do not know which one is the best job for my career. One of the jobs is as a software engineer, and although it...

So, I've been applying to several grad schools for Spring 2008. I'm graduating this semester Mid-December. ALL of the graduate schools I applied wants my final transcript before they can even begin reviewing my application. Is this how the graduate admissions work? How can I choose which...

The biggest "debate" I've seen on these cosmology forums appears to be "did the Universe, time, space and the whole whatevery actually begin with the Big Bang?" or "there is no scientific evidence the Big Bang was the beginning of the Universe, why should we believe it?" I haven't seen a thread...

Hello, I have this integral that is stumping me. Once I get the basic start then I know I can finish the rest myself it's just getting started that's stumping me. Here is the problem: \int_{0}^{4} {e^\sqrt{x}} dx First this doesn't appear to me to be an improper integral. So I should just...

It seems to me that we too frequently use the terms 'truth', 'knowledge', 'belief', 'faith', 'reality', 'existence', and 'consciousness' without first defining them. It also seems to me that these terms could be defined in many different ways, but I doubt that very many such sets of definitions...

In the beginning I have heard that the big bang came from an exploded singularity. What was this some sort of vacuum fluctuation? What are the current models of where the universe came from? Can something (the universe) be created from nothing or is it theory that energy resides in the vacuum of...

watching worldview change bit by bit is like watching grass grow. In a preprint posted today on arxiv, Abhay Ashtekar provided a bit more support to the view that black hole bounce may bridge to another big bang this paper is a write-up of a talk he gave last year. a large part is aimed at...

Near the top of this web page, there is a link to a quiz. If you take the Novice quiz called "Beginning Physics", you will find an error in question 4: Question: A cyclist changes velocity from 5 m/sec [N] to 15 m/sec [N] in 4.0 sec. What is the value of her acceleration? a) 2.5 m/sec b)...

i would like to know how to explain the beginning of universe and during high collision of high energy particles by the conservation of energy?

Frederick’s “Empty Nest” post reminded me of a thought that I have had on occasion. Perhaps it is essentially what Frederick’s post is getting at, I’m not sure. (Note: This is not intended to imply a theory but is simply meant as a question about what we know or don’t know.) What is the...

In a few days (pay day) I am hoping to buy a telescope as I've always been interested in the stars but i really am clueless as how to begin. I am hopeing to spend £150 max but would prefer if it cos a little less. I saw this on ebay but all of the specifications are beyond me...

Hey, I'm interested in Number Theory and have seen a few simple proofs/concepts related to Number Theory but at moment I have no other reference. Could somebody recommend me a Number Theory which will teach it as it's taught when you start university. I've done an A-Level in Maths in...

hello, i'm amit from israel, and i'd love to be an activated member in your forum. my first question - are there other theories about the beginning of the univers. except of "the big bang" (not religion)? thanks, amit

at the beginning of the universe, is light's speed faster than nowadays?

Where do you think truth originated from? Do you believe truth originated from society, or truth is an eternal entity? Why? ----- nwO ruoY evaH ,deeN oN <----?eeS I tahW eeS uoY oD

Thinking about the following makes my head spin...I'd be interested to hear what other people have to say. This is not mean to be a religious topic, I just want to know what others think about these...mysteries. Was there a beginning, a specific point in time where everything started...

A new / revised theory <snip> At first there was ‘nothing’. It was empty and had no bounds. One could not identify coordinates of space, nor time. Then the ‘nothing’ started to quiver. The quivers were in every direction but still there were no coordinates for direction or distance...

Hello, I'm getting done with the high school (I'm 18 years old btw) I've failed many years... sort of motivation problem... What I'm going to ask might sounds a bit confused but I really what to start "somewhere". Right know, I've got some Physics and chemistry courses at school (Nuclear...

On May 1, 1964, the BASIC computer programing language was born a senior developer at Microsoft, said his company owes much to BASIC, the software giant's first product. Microsoft's Windows operating system and Office suite still use a descendent called Visual Basic. With the help of...

hi, I am new to the forum, i am 18 years old and i am really interested in astrophysics and cosmology. there is one thing i just can't understand, what existed before the big bang? please state theories or even your own so i can least have a clue. thnx

Hello, I'm new here and am searching the internet in desperate need of help. As the title states I am a beginning physics student at the college level and today, a month into my course, I am completely lost. Please understand that I have never experienced physics until a month ago so this is...

During the last few years I have read a number of books on The Big Bang including recently one By John Gibbin; "In the Beginning." Most if not all of the books mentioned the precision with which the initial values of some important parameters had to be for the universe to have formed as it has...

http://hubblesite.org/newscenter/archive/1996/01/image/a Now this should make for an entertaining conversation on a rainy weekend. What is the plausibility that NASA has really found the beginning of time? That photograph is of the area of space at the extreme range of the HST. So what is...

The problem of infinite regress has been around for a while, as the idea of an infinite past seems to lead to absurdities. While the big bang model seemed to have removed the idea of an eternal universe, certain inflation models bring it back. Eternal inflation is one example. The evidence we...
