Observations currently indicate that the universe is infinite in size. Although planets and stars do represent non-uniformities in the spacetime structure, on the universal scale, such uniformities are randomly dispersed. On average, therefore, the universe is uniform.
We do not know whether the Universe is finite or not. To give you an example, imagine the geometry of the Universe in two dimensions as a plane. It is flat, and a plane is normally infinite.
The universe it constantly expanding, but it is not infinite, we say that it is infinite due to the idea that the universe may or may not infinitely expand, depending on the result of the heat death of the universe, or when there is no new entropy being added to the universal energy system.
In either case, you could never get to the end of the universe or space. Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.
For example, over infinite time there could, in some potential theories, be infinite universes, but only a small or relatively small real number of universes where humanity could exist and only one where it ever does exist (with a unique history).
Theories about the end of the universe. The fate of the universe may be determined by its density. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the "Big Freeze" scenario below.
Current models based on the theory of general relativity and observations of the cosmic microwave background suggest that the universe is flat and infinite. In an infinite universe, there is no “beyond,” as space extends endlessly.
Nobody knows where space ends. There is no consensus on where it ends, but there are many theories about it — all equally probable. Some scientists believe that there is no end to space and that if we were to keep travelling through space, we would just keep passing an infinite number of galaxies just like ours.
With near zero degrees Kelvin temperatures, no oxygen, gravitational and electromagnetic fields we can't see, solar radiation everywhere you look, and chunks of rock and ice hurtling at thousands of kilometers an hour – space holds more hostility to our species than any other climate we've encountered.
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang. The instant immediately following the initial singularity is part of the Planck epoch, the earliest period of time in the history of our universe.
If the Universe continues to expand, energy will be spread out so much that eventually all areas within it will remain at the same temperature. We call this the Big Freeze, when interactions between particles will cease and the Universe will remain at a frozen standstill forever.
Known as Olber's paradox, it questions how an infinite ageless universe could be mostly dark. At first glance it might seem obvious. The more distant a star, the dimmer it appears, so stars very far away are simply too dim to be seen.
Likewise, in defining our Father as infinite, we are saying that He is not finite. To be infinite means God's being and greatness have no limitations. This is what is taught in today's passage, as well as many other passages.
The Hindus consider Lord Brahma as the Creator of the Universe. Along with Lord Vishnu and Lord Shiva, he forms the Holy Trinity. As creation is the work of the mind and the intellect, Lord Brahma symbolises the Universal Mind. From the standpoint of an individual, he symbolises one's own mind and intellect.
It is impossible to know for sure if the universe is truly infinite. The observable universe is definitely finite - it is that part of the universe which is within 13.80 billion light years of us.
Another NASA astronaut, Don Pettit, described the smell of space at length in a NASA blog post, saying, "The best description I can come up with is metallic; a rather pleasant sweet metallic sensation.
GRBs are thought to be caused by the collapse of massive stars into black holes, or the merger of two neutron stars or black holes. GRBs can release more energy in a few seconds than the sun will in its entire lifetime. If a GRB were to hit Earth, it could strip away the ozone layer and cause a mass extinction event.
Thankfully, an astronaut being irretrievably stranded away from their spacecraft has never happened before. The first astronaut to float away from the safety of their ship without a tether was Bruce McCandless, who reached 320 feet away from the Challenger space shuttle on February 7, 1984.
The idea of a multiverse is the subject of much science fiction—but it's also a real possibility (or rather a set of many possibilities) that some scientists take seriously and investigate. Multiversal concepts pop up in several branches of modern physics.
Humans do die if left in outer space without a space suit. But they die for the same reason as people who are left too long underwater: lack of oxygen. The Federal Aviation Administration reports in advisory circular 61-107 that humans remain fully conscious and useful for 9-12 seconds after being exposed to a vacuum.
We cannot travel to the end of the universe as that is too far to travel. The end of the universe could be 150 billion light years away. If we travel until we have traveled for 50 years, we either go 40 light years or 400 light years.
According to the Book of Genesis, God created the universe - and all the heavenly bodies, the sun, the moon, and the stars - in six days. But according to contemporary cosmologists the universe began with a great explosion known as the Big Bang, after which the stars and galaxies slowly formed over billions of years.
No extraterrestrial life has yet been scientifically conclusively detected. Such life might range from simple forms such as prokaryotes to intelligent beings, possibly bringing forth civilizations that might be far more advanced than humans.
