We are going to share scientific articles from students in English using the blog of Twinspace and Twitter.

Marina Climent, Jesús Almera, Jordi Bellés and Javier Camacho  have studied the mass of the Earth in Sciences for the Contemporary World.


Then, we will present the work of our schoolfellow that presents some of the processes by which many scientists have attempted to calculate the mass of the Earth. The scientists who they have spoken are Isaac Newton, Kepler, Albert Einstein and Peter Higgs.


The Earth is divided into atmosphere, hydrosphere, biosphere, lithosphere, mantle and core.


To Newton, the mass is a constant that measure the opposition to change the speed of the movement of a body:

S = m·a

S = Strength (N)

m = mass (kg)

a = acceleration (m/s 2)

In this way the mass of the Earth is constant.

mass of the Earth = 5.97·1024 kg


However, Einstein, get the conclusión that the mass could become energy:

E = m · c 2

E = Energy (J)

m = mass (kg)

c = light speed in the vacuum = 3·108 m/s

And in this way, the mass of the Earth depends on the speed.

In the Standard Model, a boson, is one of two basic types of elementary particles of the Nature, as quarks and leptons. And Higgs boson is the particle that brins up the mass.

Energy of Higgs boson = 125-126 GeV

1 eV = W = q · V = 1’6·10-19 C · 1V = 1’6·10-19 J

1GeV = 109 eV


Energy of Higgs boson = 2·10-8 J


mass of Higgs boson = E/c2 = 2.22·10-25 kg


In this work of the Earth they have calculated the mass of The Higgs boson and to be able to calculate all those of these would need to equalize it.

mass of the Earth = n· mass of Higgs boson


n = m Earth / m Higgs = 2,68x1049


So they would need approximately the mass of 2,68x1049 Higgs bosons in order to equalize the mass of the Earth.

In our opinion, in  this work, they should have taken into account that we do not know all the names and contents they use, therefore it is difficult to understand. To fix it, they would have used  a language and explanation easier, but it's really interesting.
