23
Q

What comes after the formation of the universe

A

Formation of the basic elements

24
Q

Once they collide when it is hot, they would try to separate again until it cools down. With this, there is an option for the production of nucleus. This process is called

A

Nucleosynthesis

25
Q

There are a lot of protons and neutrons scattered during the Formation of the basic elements. Do these particles form something? Yes or No?

A

No. They don’t form something

26
Q

Where do the protons and neutrons attach

A

Inside the Nucleus

27
Q

What do you call the elements inside the nucleus

A

Nucleons

28
Q

What is the first element formed?

A

Hydrogen

29
Q

This era produces wavelengths and the Cosmic Microwave Background

A

Radiation Era

30
Q

It envelopes our universe and is the remnants or energy in the outer space that is also one of the evidences of Big Bang

A

Cosmic Microwave Background

31
Q

What happened in the Matter Domination era

A

Matter began to dominate and produced neutral atoms

32
Q

Equal number of protons and electrons

A

Neutral Atoms

33
Q

Unequal number of protons and electrons

A

Ion and Cation

34
Q

This is where the stars are born. It is the clumps of gases and dusts.

A

Nebula

35
Q

Fuel of the stars

A

Hydrogen and Helium

36
Q

When the Nebula keeps swirling, there’s what?

A

Accretion

37
Q

Self luminous gaseous spherical celestial body of great mass

A

Star

38
Q

A star produces energy by means of

A

Nuclear Fusion Reactions

39
Q

Explosion of the star

A

Supernova

40
Q

A place where gravity pulls so much that even light can not get out

A

Blackhole

41
Q

Supporting Evidences of Big Bang Theory

A
  1. Galaxies moving away
  2. Presence of Cosmic Microwave Background
  3. Abundance of light elements
42
Q

Massive amounts of what elements were found in the Big Bang Theory

A

Helium and Hydrogen

43
Q

Who figured the Red and Blue Shifting

A

Edwin Hubble

44
Q

If all things were moving away, it is called

A

Red shifting

45
Q

If the object is moving towards us, it is called

A

Blue shifting

46
Q

Fate of the universe

A

Big crunch and Big chill

47
Q

We would outward flight. The galaxies will slow down, eventually stops and collapses. When it reaches it’s limit then it will explode

A

Big Crunch

48
Q

The universe simply continue to expand in the vast horizon

A

Big Chill

49
Q

The universe doesn’t change its appearance and is homogenous. When an older star dies, new star replaces it. So everything remains the same. The universe neither has beginning nor ending.

A

Steady State Theory

50
Q

Extension of the Big Bang Theory. Provides solutions to unresolved problems of Big Bang Theory

A

Inflationary Theory

51
Q

Big Bang states that there should be a curvature. Everything is constant.

A

Flatness

52
Q

Determined that the geometry of the universe is nearly flat

A

WMAP (Wilkinson Microwave Anisotropy Probe)

53
Q

Dropped exponentially to undetectable level during rapid expansion

A

Monopole

54
Q

Big Bang states that space in opposite direction are so far apart they could never have contact with eachother

A

Horizon

55
Q

1 lightyear is equivalent to

A

9 trillion km
