If you say my name, I will no longer exist. What am I?

I am a seven-letter word but if you remove four of my letters I will have one left. What word am I?

What demands an answer, but asks no questions

I have an eye but still cannot see.

Who am I?

I am the beginning of the end, and the end of time and space. I am essential to creation, and I surround every place. What am I?

I have a big mouth and I am also quite loud! I am NOT a gossip but I do get involved with everyone's dirty business.

I get hot but I never sweat,
I cook food but I am not a chef,
I have a door but you can't enter me,
I have a light but I am not a lamp.
Who am I?

The more you take me, the more you leave me behind.
Who Am I?

This is a most unusual paragraph. How quickly can you find out what is so unusual about it? It looks so ordinary, you'd think nothing was wrong with it. Actually, nothing IS wrong with it. But it is not as ordinary as you might think. If you think about it for a bit, you will find out why it is truly so unusual. So what is it? What is so unordinary about this paragraph?

If,

A = 1

B = 2

C = 3

...

...

Z = 26.

Based on above rule, you need to find an eleven letter word whose letter sum is equal to 52.
