What are some theories of the creation of the universe?

In summary, Han-se Kim is a 9-year-old student seeking help with a physics project on the topic of the Big Bang theory. The tutor recommends two resources, an article and a tutorial, that provide information and evidence surrounding the theory.

Hi, I'm new to this forum and I thought I'd ask for some help with my research paper.

Well I am a Senior in Highschool and I take IB (International Baccalaureate [Google it]) courses which are basically super advanced courses. Anyway, one of the requirements is that I write a 3,500-4,000 word essay of a topic of my choosing.

Well in my research paper, I wish to compare two theories of the universe in order to conclude which seems more plausible than the other.

What I'm asking from you guys are the names of a couple of modern theories of how the universe was created.

I also want to know where I can look for more information on these theories. (Links, books, articles etc...) *NO WIKIPEDIA*

So, can you guys help a kid out?

*Note: I know this belongs in the homework help section, but I didn't see a section there that didn't talk about the universe as much as this section did. :D

Just fyi, you should be happy to make use of Wikipedia to start your research. They tend to have excellent introductions to a variety of topics, as well as many references for further reading (references that you can actually make use of).

I agree. Certainly for science topics, Wikipedia is a perfectly good platform to start your research. I think many of the perceived problems with it exist more in the politics and current affairs areas rather than the science pages, which tend to be pretty good (with some exceptions). Many professional scientists make use of Wikipedia all the time.

As to the question, you might want to be a little more specific. So, as far as mainstream science goes, the strong consensus model is the Hot Big Bang theory. There is no single alternative that is set against this, though there are a small number of other ideas around with only a few adherants.

However, the HBBT paradigm simply asserts that the Universe began in a hot dense state, exactly how that happened (or why it happened) is unknown. There are various proposals, the most plausible being inflation, however there are many different theories about how and why inflation occurred and exactly how it proceeded.

Moving beyond that, there is the question of what happened before inflation (which is obviously linked to the question of why inflation occured). There are a number of different theories around, although there is precious little evidence available to decide between them. Some even argue that we will never be able to answer this kind of question.

So, I hope that helped, but as I say you will have to be more specific about what you mean by 'theory of the Universe'. From a historical perspective, you could talk about the "Steady State Universe" (the key person to look for there is Fred Hoyle, also Halton Arp although the former is (was) much more sane) as compared to the "Expanding Universe". I say historical because this debate is done and dusted now, but before we had the kind of data we have now was a very interesting and lively debate. If you chose those two ideas to write about you could talk about what made each one plausible at the time, and then explain what it was about newer data that came along that settled the argument in the favour of the expanding universe.

Project

Hi. My name is Han-se Kim. I'm 9 years old and I'm doing a physics project. It's about physics and I need help. I'm up to chapter 2- the big bang theory. I urgently need help. Can you help me my posting a document with some information of the big bang theory and attach it to your reply.

Can you help a kid?

This is my favorite article on the subject:
http://www.talkorigins.org/faqs/astronomy/bigbang.html

It's all about the evidence surrounding the big bang theory.

What are some theories of the creation of the universe?

There are several theories that attempt to explain the origin of the universe. Some of the most commonly discussed theories include the Big Bang theory, the Steady State theory, and the Inflationary theory.

What is the Big Bang theory?

The Big Bang theory proposes that the universe began as a hot, dense singularity and has been expanding ever since. This expansion resulted in the formation of galaxies, stars, and planets. The theory is supported by evidence such as the cosmic microwave background radiation and the observed redshift of distant galaxies.

What is the Steady State theory?

The Steady State theory suggests that the universe has always existed in a constant state, with matter being continuously created to fill in the gaps as the universe expands. This theory has fallen out of favor in recent years due to the lack of evidence to support it.

What is the Inflationary theory?

The Inflationary theory proposes that the universe underwent a rapid period of expansion in its early stages, causing it to expand faster than the speed of light. This theory helps explain certain observations, such as the uniformity of the cosmic microwave background radiation. However, it is still a subject of ongoing research and debate.

Are there other theories of the creation of the universe?

Yes, there are other theories that have been proposed, such as the Multiverse theory, the String theory, and the Ekpyrotic theory. These theories are more speculative and have not yet been supported by empirical evidence.
