What is the most dense material known to man?

Answer 1

Barnards star has a mass of between 0.15 and 0.17 solar masses.

Answer 2

The densest known material is the Element Osmium, at about 22 tonnes per cubic meter. The densest theorized material would be white dwarf/neutron star matter, which could be millions of times denser. Of course, since it occupies no space at all, the density of a black hole's singularity is technically infinite.

Answer 3

Our own Sun (which is a star) has a mass of about 333,000 times the mass of Earth. In kilograms, the mass of our Sun is about 2×1030 kg. Other stars have masses which vary from about 8% of the mass of our Sun (smaller objects are "brown dwarves"), up to over 100 times the mass of our Sun.

Answer 4

As the term is usually used, the "critical density" is that which makes the universe "closed" ... its expansion will eventually slow down and stop.

Our current best estimate is that the universe contains considerably too little mass to be at critical density, and it will expand forever.

Answer 5

As we can't be totally sure, any answer is an estimate and will change as technology and observations evolve.

The current estimate is 1.59486 × 1055 kg

Answer 6

The total mass of the Universe is: 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 tonnes

E = MC^2

(10,000,000,000,000,000,000,000,000,000,000,000 000,000,000,000,000 tonnes) * 299,792,458 (m / (s squared)) * 10 = 2.99792458 × 1061 newtons

So your answer would be: the Universe has * 10 = 2.99792458 × 1061 newtons of energy (approximately).

Answer 7

Any answer that anyone could give you would be a guess, and probably a bad guess at that. Let's just say that it's probably way higher than anybody's guess.

Think of it this way; we think there may be such things as "black holes". Black holes cannot be detected by anything except their gravity, and we can't easily detect gravity from much of a distance. So there could be ga-zillions of black holes and we wouldn't have a clue.

it seems to me that mass= energy= EM field=0, that is the toal mass of the universe.

Answer 8

The total amount of energy and mass in the universe does not change. Neither energy nor mass (matter) can be destroyed. One kind of energy can be converted to another kind of energy and mass (matter) can be converted to energy and energy can be converted to mass.

The total mass of the *observed* universe is something like 3 x 10^55 grams.

The universe is 10^53 kg full of mass. We have a huge universe.

It does not change because energy can never be created, nor destroyed. Energy is never lost. It always goes somewhere, or converts to a different type of energy

Answer 9

the answer is: unknown

Scientists estimate that the universe is about 10 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 tonnes, or about 1.0×10^49 and growing.

Answer 10

The mass of the solar system is about 1.992 x 1030kg.

The Sun accounts for about 99.86% of that mass.
