Is the Big Bang the most powerful explosion?

The biggest explosion in the Universe since the Big Bang has been discovered by astronomers. The blast came from a supermassive black hole at the centre of a galaxy hundreds of millions of light-years away. “This is the most energetic outburst we have seen since the Big Bang,” she told the PA news agency.

What is stronger than the Big Bang?

Pune telescope detected an explosion five times bigger than the Big Bang 390 million light years from Earth. The blast, which released five times more energy than the previous record holder, came from a supermassive black hole at the centre of a galaxy hundreds of millions of light-years away.

Can a Big Bang destroy the universe?

This would destroy not only stars but black holes, planets, and even whole galaxies. The universe would literally rip itself to pieces. The last is called the Big Freeze. Instead, according to them, the cosmos is likely to end in another Big Bang.

How big was the Big Bang?

In the first period, the universe grew from an almost infinitely small point to nearly an octillion (that’s a 1 followed by 27 zeros) times that in size in less than a trillionth of a second. This inflation period was followed by a more gradual, but violent, period of expansion we know as the Big Bang.

What is the black hole theory?

A black hole is a region of spacetime where gravity is so strong that nothing — no particles or even electromagnetic radiation such as light — can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

How hot was the universe at the Big Bang?

theoretical models in cosmology In cosmology: The hot big bang Given the measured radiation temperature of 2.735 kelvins (K), the energy density of the cosmic microwave background can be shown to be about 1,000 times smaller than the average rest-energy density of ordinary matter in the universe.

Was the Big Bang really an explosion?

(sometimes l.c.) the cosmic explosion of matter postulated by the big bang theory. big bang. The violent explosion of an extremely small, hot, and dense body of matter between 12 and 18 billion years ago. It is viewed as the earliest event in a widely held model of the origin of the universe.

What are the weaknesses of the Big Bang theory?

Here are some of the weaknesses of the Big Bang Theory below:- Weaknesses of the Big Bang Theory The main disadvantage of the Big Bang theory probably lies in its inability to explain where the original “ball” of energy came from that did the expanding (the “Bang”) to form the universe and the space-time that it occupies….

How do we know the big bang actually happened?

When the big bang happened, after the initial moments of high, intense energy radiating from the density and heat of the singularity, the universe expanded rapidly so that everything became less dense and cooled down. In just a few seconds, the expansion caused the singularity to stretch out all across space (Coffey).
