What do scientists think will eventually happen to the universe?
If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.
What do scientists know about the future of the universe?
The future of the Universe will be determined by the struggle between the momentum of its expansion and the pull of gravity. The vertical scale indicates the size of the Universe. For the next several billion years, the expansion of the Universe gradually slowed down due to the effects of gravity on matter.
What happens after the dark era of the universe?
The universe fades to black (holes) White dwarfs, brown dwarfs, and neutron stars are expected to eventually die through a process known as proton decay, when the subatomic particles they are made of literally fall apart.
What is the fate of the universe summary?
The Universe will collapse in on itself: If the mean density exceeds the critical density, then the expansion of the universe will eventually cease, and the universe will begin to contract. Eventually, a fireball like that which initiated the universe’s expansion will result.
Which theory explains why the universe is expanding?
The theory of relativity predicts phenomena associated with the expansion, notably the redshift-versus-distance relationship known as Hubble’s Law; functional forms for cosmological distance measurements that differ from what would be expected if space were not expanding; and an observable change in the matter and …
Where in the universe are we?
Well, Earth is located in the universe in the Virgo Supercluster of galaxies. A supercluster is a group of galaxies held together by gravity. Within this supercluster we are in a smaller group of galaxies called the Local Group. Earth is in the second largest galaxy of the Local Group – a galaxy called the Milky Way.
How do we know we exist in this universe?
Ever since the evolution of the sensory neuron, organisms have been using these amazing peepholes into existence to direct the course of their lives. Now, humankind has elevated the role of these senses, and even created technological extensions of them, in order to find order and true knowledge of this Universe in which we exist.
When did the universe begin?
Our universe began about 13.81 billion years ago. (That humans have discovered this fact with such great precision is itself a testimony to the power of science. It is truly an astonishing discovery if you stop to think about it, and we are the first living people who have known this.)
What is the relevance of cosmology to human nature?
Cosmology, broadly conceived as referring to the current state of the universe as well as to it origin and fate, is obviously applicable to our concerns. Biology is also most important; it is the science that tells us what human nature is.
Are there things that science has yet to discover?
Yes, there are an infinite number of things that science has yet to discover, there may be truths that science cannot by its nature uncover, and there may be other means by which to tease truth from reality than the scientific method.
