It is believed that the universe first formed approximately 13.7 billion years ago.
no because scientists think that earth is the only planet in the universe that supports life :3
Bacteria were the first cells.
Albert Einstein is best known for developing the theory of relativity, which fundamentally changed the way scientists think about space, time, and gravity. His equations laid the foundation for modern physics and led to incredible advancements in our understanding of the universe.
Scientists believe that gravitational forces were primarily responsible for clumping matter together to form the first stars after the Big Bang. As the universe expanded and cooled, regions of density fluctuations in the primordial gas began to collapse under their own gravity. This process led to the formation of protostars, which eventually ignited nuclear fusion, marking the birth of the first stars.
There are many across the visible universe but the closest huge one is believed to be in the center of our galaxy - pulling the stars, planets various stuff in a counterclockwise rotation.
The big bang or a wormhole
Scientists think that the universe was created by the big bang, and that energy came out of energy pockets and turned into mass ( E=MC2 ). The universe then started expanding, and heavier elements in the periodic table started to form (at first there was only Helium and Hydrogen).
It would be 76476474585475478780 years ago, which is before the time scientists think the Universe started.
Yes
our universe is currently 13.7 billion years old and about 155 million years after the big bang , first star is born and by this way stelliferous era was started .
They estimate the age of the Universe in more than 12 billion years.
Flat model
no because scientists think that earth is the only planet in the universe that supports life :3
scientists think that they do. there is one in every galaxy. also in ours
Scientists believe that humans first appeared during the Quaternary period, specifically in the Pleistocene epoch. This period started about 2.6 million years ago and continues to the present day.
Many scientists consider the possibility life exists elsewhere in our universe (and more particularly even within our own galaxy) quite likely. A few do not think it is likely.
DNA I think
