What do scientists believe caused the big bang?

The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. Astrophysicists dubbed this titanic explosion the Big Bang.

How will you explain the big bang theory by relating it to Mass?

Matter and energy cannot be created or destroyed, but, can be in different forms. Matter and energy are two forms of the same thing. The Big Bang originated all of the mass of the entire universe so presumably a large amount of mass was initially still in relatively close proximity to itself for a while.

Why is the steady-state theory not accepted?

While the steady-state model enjoyed some minority support in the scientific mainstream until the mid-20th century, it is now rejected by the vast majority of cosmologists, astrophysicists and astronomers, as the observational evidence points to a hot Big Bang cosmology with a finite age of the universe, which the …

Are there any problems with the steady-state theory?

The Steady State Theory began to fade in the 1960s after the discovery of quasars. A quasar is thought to be a luminous galactic core, powered by a super-massive black hole. Quasars are so far away from us that their light has taken several billion years to reach the Earth.

How does the model you created help to show that the steady-state theory is inaccurate?

How does the model you created help to show that the Steady State theory is inaccurate? Compare and contrast your experimental procedures with the Big Bang theory. The steady state theory is inaccurate because the model does not create new matter, it just expands further the matter that is already present.

What are the features of steady state theory?

steady-state theory, in cosmology, a view that the universe is always expanding but maintaining a constant average density, with matter being continuously created to form new stars and galaxies at the same rate that old ones become unobservable as a consequence of their increasing distance and velocity of recession.
