Is the universe expanding outward or inward?
It is an intrinsic expansion whereby the scale of space itself changes. The universe does not expand “into” anything and does not require space to exist “outside” it. Technically, neither space nor objects in space move.
Is the universe expanding into itself?
The universe is everything, so it isn’t expanding into anything. It’s just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there’s no center they’re expanding from and no outer edge to expand into anything else.
Is Big Crunch possible?
The Universe might yet collapse in a devastating “big crunch”. Physicists have shown that even though its growth is speeding up, it could still start to implode by the time it is only twice its current age.
Is the universe expanding into more space?
The collection of galaxies that make up the universe is moving through space; therefore, the universe is expanding into even more space than it already encompassed. In our new picture, though, the galaxies are just raisins spread throughout the dough – their presence is largely irrelevant to the question of the universe’s expansion.
Why did God create the universe in outward motion?
Expansion of the universe is just one possible explanation for the redshift of starlight. If this theory is correct, God surely has his own purposes for creating a universe in outward motion. Perhaps it provides stability: In a static universe, gravity would cause all galaxies to eventually collapse inward.
How does the universe change in brightness as it expands?
In addition, the light is stretched as the Universe expanded, further dimming the light. So in an expanding Universe the most distant galaxies should have hundreds of times dimmer surface brightness than similar nearby galaxies, making them actually undetectable with present-day telescopes.
What is the Big Bang theory of the universe?
In contrast, the Big Bang theory tells us that in an expanding Universe objects actually should appear fainter but bigger. Thus in this theory, the surface brightness decreases with the distance. In addition, the light is stretched as the Universe expanded, further dimming the light.
