But if black hole collapses to singularity, then is it 2d, 1d or 0d. Anyway, I can't just imagine any thing existing in Dimensions other than 3D. 0,1,2D are just contained in Mathematics, but how can they exists in real space-time? Its kinda paradox that a star must collapse to a point to form a...

Please read this article: http://www.nature.com/news/2004/040712/full/040712-12.html I can't understand, which it says This suggests that black holes do not actually narrow to a singularity at all I can't understand, please explain :redface:

kuenmao said: The frequency of the light emitted is directly proportional to the energy level difference between the excited state and the rest state of the electron. That brings me to ask a deeper :redface: question: Why does it influences the frequency only but not the wavelength or velocity?

Just a small question: If the wavelength of light changes in a denser medium then why don't we percieve color red as some other color? :eek: Also, why does only wavelength changes not the frequency but not the vice versa? What determines this?

Likes: 1)I like BioTech becaude it teaches you How to manipulate with building blocks of life i.e. DNA. More Imp It will possibly teach me basics of cloning. ah! Also Biotech is now at a position where IT was in mid 90's. 2)I like Instrumentation & Control coz it includes Robotics & AI (my...

I am going to pursue Engineering at graduation level. But I'm confused about which type of engineering is best. I have three options: 1) BioTechnology 2) Instrumentation and control 3) Information Technology All are equally interesting to me. Please help me decide which one has the best...

First off all we need to define STATE OF MATTER! Is it just a somewhat similar arraangements of atoms or something else?

I just wanted to ask How many interpretations of QM are there and which one is considered best by the scientific community? P.S.: Is there need for any QM interpretation et all?

What are these extended electrons? Please explain it in simple language.

Suppose time travel is possible. Then will it violate the law of conservation of energy??

The Law of existence... The Law of existence. Anyone who knows this law, exists. Anyone who has communicated(one way or two way, in any form) with someone who knows this law, exists. Nobody else exists. Assume that 1. This law is true. 2. I know this law. 3. You cannot communicate(one...

What is Light? What is Light? Is it a EM wave or a stream of photons? Is there any theory which can explain all the phenomena of light? P.S.: Another question, What makes glass transparent?

What is Anthropic principle? And does it have to do anything with science?

I was just wondering why a system wants to mininmize its energy? Why a system wants to be stabalized at all?

I just wanted to ask what is the state(solid,liquid,gas) and shape of electron? I know this is a weird question. But, electron has to be something? Please tell!
