Hint: Three types of substance are thought to consist of the Universe: normal matter,' dark matter' and 'dark energy.' The atoms that make up stars, planets, human beings and every other visible object in the Universe consist of normal matter.
Complete answer:
1.Around 73 percent of the visible universe's mass is in the form of hydrogen. Helium makes up about 25 percent of the mass, and only 2 percent reflects all else.
2.In the hot, dense conditions of the birth of the universe itself, the low-mass elements, hydrogen and helium, were manufactured.
3.Until the universe had spread out and subsequently cooled, hydrogen did not appear enough to form the first protons and neutrons, and later simple atoms.
4.Within about 3 minutes after the Big Bang, conditions cooled enough to form hydrogen nuclei for these protons and neutrons.
5.The simplest element in the universe is hydrogen with just one proton and one electron (it's the only element without a neutron), which explains why it is also the most abundant, Nyman said. Two protons, two neutrons and two electrons are in helium.
6.Hydrogen may also be toxic, however. According to Airships.net, hydrogen gas interacting with oxygen contributed to the Hindenburg blimp disaster that killed 36 individuals in 1937.
7. In addition, hydrogen bombs can be extremely destructive, although they were never used as a weapon, "Nyman said," only demonstrated in the 1950s by the United States, the USSR, Great Britain, France and China. Like atomic bombs she said.
\[\therefore \] The universe is made up of Hydrogen
The correct option is (B) .
Note:
Hydrogen is present in the sun and most stars, and most of the planet Jupiter is made up of hydrogen. Hydrogen is present on Earth in greater amounts than water. It is only present in tiny quantities in the atmosphere as a gas, less than 1 part per million by volume. Hydrogen bombs use a mixture of nuclear fusion and fission reactions to cause damage, and when detonated, they emit both radiation and mechanical shock waves.
