One of the most amazing facts ever - sounds like BS

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?

At that level of compression (and with so little mass) gravity would be negligible, it would be down the to the much stronger nuclear forces and if they can hold without the gravity of the much much larger mass of the star

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).

Again it's only 900 times the mas of the great pyramid, that's only something like a large asteroid, so no real gravity :p


But if it did expand a tea spoon piece of matter expanding to massive gas cloud it could form would be devastating to anything near by.


Either way it would be very difficult to study it, any spacecraft near it would be destroyed almost instantly.

Gravity is a pathetically weak force :p

Just think a fridge magnet can overcome the entire gravitational pull of the earth.

True, forgot gravity was a very weak force... :o

However does your last comment not contradict this comment?

Also if you dropped an object from one meter above a neutron star it would hit the surface in a microsecond and be travelling at 7.2 million kilometers per hour.

Can you tell I haven't done any proper Physics/chemistry in a few years... :(

A neutron star would be about twice the mass of a the sun compacted in a much smaller space than the sun (according to wiki it's diameter would be about 12km 60,000 times smaller than the sun).

So much much denser, but also as gravity follows an inverse square law ( i think, it's been some time since i did this) the gravity on it's surface would be massively higher than the gravity on the surface of even the sun.

Neutron stars are the remains of a massive stars supernova and collapse that didn't quite have enough mass to make a black hole.



From wiki

The gravitational field at the star's surface is about 2 × 1011 times stronger than on Earth. The escape velocity is about 100,000 km/s, which is about one third the speed of light.

Entirely true afaik.

A physicist once told me that it is possible to walk through a wall due to this concept.

Of course the chance of all of your atoms going into the spaces of all of the walls atoms was like 9.9 x 10^90890809789789789789798797

Also you could get stuck inside the wall :eek::eek::eek::eek::eek::eek: :p

That might explain why some people disappear.

This is from a BBC series called The Story Of Science which I was watching today and I just had to share it.
So scientists what is your take on this?
Sounds unbelievable.

I couldn't be certain of the size of thew cube without more calculations than I care to do and a lot of estimating, but it sounds plausible. Matter is almost entirely nothing. Weird thought, but true.
 
Two empty cardboard boxes are mostly empty space*, yet you can't make them occupy the same space... that's a horrid over-simplification, but isn't it basically the same principle?

*OK, OK, it's air!

For the dudes without sound, what was the amazing fact in the video?

I'm paraphrasing...

If you take every atom that makes up every single person on this planet and compress them, taking the space out of the atoms, you would end up with a lump of matter the size of a sugar cube.
