What Is Space Made Of

In space no one can hear you scream.

What is space made of. They are the constituents of space. Hydrogen is the most common element found in the universe followed by helium. The solar wind made up of plasma and other.

The atoms of space are not the smallest portions of space says daniele oriti of the max planck institute for gravitational physics in potsdam germany. With no air to scatter sunlight and produce a blue sky space appears as a black blanket dotted. It s made of galaxies stars planets black holes comets asteroids and all the other cool space stuff yes there is a lot of amazing space stuff but if we add it all up it s just a very small part of the entire universe.

Further space is a vacuum meaning that sound cannot carry because molecules are not close enough together to transmit sound between them. And not only is space big we don t know what it s made of. And we don t fully understand what it is.

There s a lot more out there. This is because there is no air in space it is a vacuum. Outer space is not completely empty it is a hard vacuum containing a low density of particles predominantly a plasma of hydrogen and helium as well as electromagnetic radiation magnetic fields neutrinos dust and cosmic rays.

Outer space begins about 100 km above the earth where the shell of air around our planet disappears. Together they make up nearly all ordinary matter. Sound waves cannot travel through a vacuum.
