Is it time to dethrone the Big Bang theory?

Do you understand enough about the Big Bang theory to question it? Getty Is cosmology, the big bang theory is king. It hasn’t always been that way, but over the years, the evidence has increased and most of the astronomers are convinced that it is the best we have. Why do many people hate it? Black holes, invisible dark matter …

Why the Big Bang produced something rather than nothing

In 1967, Dr. Sakharov proposed a recipe for how matter and antimatter could have survived their mutual pact of destruction. One condition is that the laws of nature may not be as symmetrical as physicists like Einstein assumed. In a purely symmetrical universe, physics should work the same way if all particles change their electrical charges from positive to negative …

Observe the evolution of a galaxy, from the Big Bang to today

To learn how galaxies change over time, scientists have created the most complex simulation of a galaxy called TNG50. The data from this simulation was used to create the above video, which shows the evolution of a massive galaxy from the beginning of the Universe to the present day. In the main window of the video denser gas is shown …

The lonely fight of the best cosmologist against the big bang theory

The Nobel Committee honored Peebles last month for developing the prevailing theoretical framework for the young universe 14 billion years ago since the mid-1960s James Peebles won this year's Nobel Prize in Physics for helping transform the field of cosmology into a prestigious science. But if there's a term he hates, he's called "Big Bang Theory." The leading explanation for …

Big Bang Theory: Scientists discover what happened before the big bang Science | news

Now, an international research team believes that they know the timescale of the early universe, measured in trillionths of a second. But it is complicated. And we are still not there. There are two theories about what happened exactly 13.8 billion years ago when the inexplicably large universe emerged from something so unimaginably small – one hundredth of a billionth …
