Diamond is brittle...
Diamond is harder than Titanium...
Titanium will melt under super high heat...

So what's the hardest thing (if possible, as hard as a diamond) but not as brittle as a diamond?

My question is...

Could we built a structure a mile high? Five miles high? Higher? Perhaps a monolithic structure such as a single column tower or something similar would be more difficult but what if the object had an enormous/deep base - say 10 miles for example - could it support a structure one mile (or more) high? What would prevent this? Gravity? Wind sheer? Techtonic movement?

Regards
Conor

I really want to see the Perseids this year, but I can't figure out when to look. In this article http://www.nightskyinfo.com/sky_highlights/ it says that the Perseids will peak before dawn on the mornings of August 12 and 13. Can anyone tell me a more precise timing? I live in Europe. Thanks!

In the last month there has been many earthquakes throughout the world. This somewhat worries me, because it hasn't hit a populated area yet, exception of the one in Japan. There were series of major earthquakes this week too. I just had a gut feeling that soon its going to hit a major city.

There are many forms of energy being discussed around the world right now. I’ve recently stumbled onto a topic in Australia. They apparently have found a way to make what they have coined a “steam cell’ which should not be confused with a stem cell. According to company called Enginion AG, they have found a way to make steam in about 30 seconds. Does anybody know exactly about the process which they use to achieve this?

2. how come the atomic size of the elements in the periodic table decreases as you go across and increases as you go down?

3. how come the ionization energy of the elements in the periodic table increases as you go across and decreases as you go down?

4. how come the electron affinity of the elements in the periodic table increases as you go across and decreases as you go down?

as we use up the oil ,gas,coal the earth gets lighter right so why doesnt the gravity of the sun pull the earth into it seems to me if gravity is pulling on a object that weighs say 10 pounds and then suddenly the object only weighs 8 pounds shouldt it be pulled towards it faster because of the less weight
