Infinite Universe

we enter into the domain of extra-galactic cosmology, the big bang theory and the evidence for an expanding universe. scientists construct theoretical models that are mistaken for reality by millions of people who encounter them in authoritative textbooks and in popular presentations., however, that even within the narrowly defined domain of astrophysics, new observations may arise that fundamentally challenge these models and reveal them to be mere systems of speculative ideas. , this fundamental challenge shows the need for drastic revisions in the modern understanding of the universe as a whole-revisions that thus far have not been seriously considered in the scientific community.
Let us begin with the theory of the big bang. Basically, this is the idea that in the beginning (or before the beginning, if you will), all matter in the universe was concentrated into an infinitely small volume at an infinitely high temperature and pressure. Then, according to the story, it exploded with tremendous force. From this explosion rushed a superheated, ionized gas, or plasma. This plasma expanded uniformly until it cooled sufficiently to form ordinary gas. Within this cooling cloud of expanding gas formed galaxies, and within the galaxies took birth generations of stars. In turn planets such as our own earth formed around the stars.
But here's a fact that few people realize: Even with the most powerful telescopes, it is not possible to actually see galaxies moving away from us. The images we see are static, and scientists would not expect them to show visible motion, even if observations could go on for centuries.
So how do we really know the universe is expanding? All we have to go on is the light and other kinds of radiation that travel to us from across the reaches of interstellar space. What scientists do is first assume that the earthly laws of physics apply without change throughout the universe. They then try to figure out how processes obeying these laws could produce the observed light.
To understand how scientists have used this way of analyzing light to conclude that the universe is expanding, let us go back into the history of astronomy and astrophysics.Until the discovery of stars in Andromeda, it was generally thought that all celestial bodies were located within the boundaries of our local Milky Way galaxy. But with this development and the discovery of other, more distant galaxies, all that was changed. The dimensions of the universe expanded beyond comprehension.
Up until the early part of this century, scientists believed that the basic objects in the universe were static in relation to one another. Then in 1913 the American astronomer Vesto Melvin Slipher came to study the spectra of light coming from a dozen prominent nebulae and concluded that they were moving away from the earth at speeds of up two million miles per hour.
How did Slipher reach this astonishing conclusion? For some time, astronomers had been using spectrographic analysis to determine the elements present in the stars. It was known that the spectrum of light associated with a particular element will show a characteristic pattern of lines that serves as a kind of signature for the element.
Slipher noticed that in the spectra of galaxies he studied, the lines for certain elements were shifted toward the red part of the spectrum. This curious phenomenon is called a "red shift." Slipher interpreted the red shift as a Doppler effect, indicating that the galaxies were moving away. This was the first major step toward the idea that the entire universe is expanding. (If the lines in the spectrum had been shifted toward the blue end of the spectrum, that would have indicated that the galaxies were moving toward the observer.).
Doppler predicted a similar effect for light waves. For light, an increase in wavelength corresponds to a shift toward the red end of the spectrum. Therefore the spectrum of an object moving away from an observer would tend to be shifted toward the red. Slipher chose to interpret his observations of galaxies in this way, as a Doppler effect. He noted a red shift and decided the galaxies must be moving away.
Another step toward belief in an expanding universe took place in 1917, when Einstein published his theory of general relativity. Before Einstein, scientists had always assumed that space extended to infinity in all directions and that the geometry of space was Euclidean and three-dimensional. But Einstein proposed that space could have a different kind of geometry-four-dimensional curved space-time, in which space could curve back on itself.

I hope there is a planet that is 3/4 covered with marijuana out there. when i die, i want to be reborn there.

If the universe goes on forever, everything possible must happen not just once but an infinite amount of times, thus since you know you are possible as you exist, you must exist not just once but an Infinite amount of times, and since space & time are relative you must exist not just Infinity throughout space, but eternal throughout time and thus your life is eternal and thus since this life appears finite, there must be an after-life.

I see it this way - our galaxy is in the group of galaxies, group of galaxies are in universe, universes are in "something", and its in something even bigger, and it is in our dimension, there are other dimension, wich are ... Infinite consciousness? maybe :D really big thing

[Landonsiemens]

im so fucked right now and this is life changing

[whatstheoutcomeof]

the existence of our conciousness is depends on the work of our brain, our physic may be eternal it just changing shape into corpse, ash or whatever but our conciousness have it's finite time. If life is identical with conciousness, not physical thing, how people think there's after-life?

@The2012phenomneon How do you know that the universe goes on forever, and how it make a conclusion that everything possible is infinite?

[nblackmatter]

The Infinite Universe is occupied by non-living things as we are living things we must be conversion of non-living things in to livings and living things in to non-living things. Our current and after-life is the Infinite cycle. During death we get pain because we must convert in to non living things. After-life when we get another life that time also we get pain before new life

@nblackmatter two thumbs up

There is no question as well as answer of a god. The Reality is Infinity even if there is a vision it is a temporary in the absence of vision also Infinity is there. Those formulas made by human are also temporary because Physics, Chemistry and  Biology changes Universally. It is Infinite Conversion human life is a micro part of this Conversion this is Infinite Reaction no one is creator nor destroyer nor controller. Finally this is Infinite Universal Reaction
