Embarrassing Questions

I'm sure each of us has a huge list of unanswered questions. Here's a blog for archiving all such questions. It would potentially serve to get us and others some answers which have been eluding us for a long time. The answers can come in the form of comments. Please note that we should stick to questions we had honestly asked when we were in school, or pre-university college. We are strictly barred from trying to find answers to our research problems!

Does it stop somewhere??????

Hi!

Everything is "within" something!!! We are in a room, room's in a building, building in a colony, colony in a city, city in a country, country in a continent, continent on Earth, Earth in solar system, solar system in a galaxy, galaxy in the universe.............what's beyond that? Is the Universe in another BIGGER entity? If it is, where's that BIGGER entity housed? Do we stop somewhere????

good question. To rephrase it, if if the universe is ever expanding, there must be room for it to expand into.Then, isn't the 'extra space' already a part of the universe anyway ?
Well, the answer isn't known.Solving this would leave many astronomers and philosophers unemployed :)

Totally agree with Karthik.

As a matter of fact, his answer doesn't leave any room for expansion towards perfection :)

In fact, the other way round is also true! How much smaller it can get! At one point of time, we thought that molecules were all there was to matter......then came atoms, then electrons, then even smaller particles..........do we stop somewhere? Is there something called "The smallest Building Block" for matter????????

Pritesh,

As a matter of fact, there is! I had attended one lecture at NIAS last year, titled, "Time : From antiquity to Einstein and beyond." The speaker explained all the key relativity concepts so well that even I could understand. In that he mentioned, there is a kind of barrier distance = 10e-31metres, below which there could be nothing (or it's a basic "atom" as long as distance goes).

That was one interesting talk. I'll send the presentation/link to author's page sometime...

I think the limitation could've been more because we can't "detect" or "analyze" anything smaller than that! I won't like to believe that there's nothing smaller than that!

i guess particles smaller than that simply would not be stable on their own.The barrier must simply be a theoretical result.Or maybe, particles smaller than that would be stable for not longer than
10e-50 seconds, which will make it somewhat hard to detect them :)

An ever expanding universe shouldn't be difficult to prove / disprove. It boils down to simply proving if matter can be created (no matter how infinitesimely small) or not. This does not necessarily prove that anything is bound, but simply proves that things metamorphasise to what they are.

Hey Diana and Sathya, I guess I didn't convey my thing properly! I meant to say that HOW big things get? Everything is within something. What's Universe inside? What happens after Universe ends? Ennui????

Rephrasing that question: What is the limit of your imagination? If you can imagine something larger, you'll give it a name and try defining it. I haven't heard anybody speak beyond the universe. hence I would comprehend universe as everything bigger than galaxies.

As you reach the edge of your imagination, you tend to encompass the rest as a single entity.

Since I don't have the privilege to post in this blog, I am posting a question through the comments box:
Why are most of the objects around us rectangular in shape? If you look around within your house, the cot, the walls, the cupboard, the calender, the TV, the fridge etc etc all are rectangular in shape. The list is un-ending. Does anyone have a clue?

I guess most things are rectangular by design. If they were round, for instance, they would roll away and we would have to keep bringing them back to their original positions:)

I haven't read this through, but what i feel is that the layman's (my) definition of the universe is that the universe consists of everything.
So by definition, there can be nothing which is outside this set.

(I think this question was posted ages ago.. don't think anybody's gonna reply)
