One of the most amazing facts ever - sounds like BS

How can you say no one has proven it?

When they say a teaspoon. They don't actually mean a teaspoon :rolleyes: as said, it was a teaspoon sized amount, as stated by Tefal (5ml)

It's easy to prove. If you know the dimensions and mass of the pyramid of Giza, then you can work out its density. If you get some mass of a neutron star, nothing big, let's say about 60 kg, you can work out its density as well.

Then, you put 2 and 2 together to get 4
 
I remember reading somewhere the the all matter in the universe could be compacted into something like the size of the Earth if all the space was removed. It's a scale that is probably the most difficult to comprehend. If a hydrogen atom was the size of a football field the nucleus would be an apple on the centre spot...
 
Remember that the universe was the size no bigger than a full stop. So concentrating all that mass into a full stop makes fitting 6 billion people into a cube look like child's play :p

It's not like your really going to compress that much matter down just to prove a pointless fact, but it is a fact non the less. We know how big an atom is, we know how much empty space there is, we can make a guess at how many atoms is approximately in the average person, we know roughly how many people there are........ ergo it can be inferred as a fact without having to actually do the experiment (Which would be ridiculous!)
 
right, with the neutron star, iirc the matter in that is so compressed the electrons have actually bonded/merged with their own protons.

if you where to remove a scoop of it and place it free in space, would it explode violently and expand back to a fairly large gas cloud, or would it stay as a very small amount (with maybe some expansion) due to the very strong nuclear forces holding it together?

I'd go with explosion, having said that, could it not implode?
 
Size is all relative. It is Mass that is important. Like some have said here already all the Matter in the universe was once compressed into something so small as to be invisible.

Google 'singularity' for some mind-bending stuff.

It may just stay like it is? I guess it depends if the gravitational force it's exerting (due to it's density) is higher than the forces within the atoms pushing them out?

Could make an epic weapon. Just a teaspoon size piece left in the middle of space could cause chaos due to it's massive gravitational force, like a marble through paper.... :p (I think).

Either way it would be very difficult to study it, any spacecraft near it would be destroyed almost instantly.
 
I suggest everyone read Hawkings book. You can pick it up for around a fiver and it's a good read, some really insane physics but all worded and explained for a person slightly smarter than a layman.
