What is happening to the universe since the big bang?
Since the Big Bang, the universe has been expanding. Galaxies are moving away from each other as space itself expands. This expansion is happening at an accelerating rate, driven by dark energy.
Where does expansion happen?
Expansion in the universe happens everywhere, as galaxies move away from each other due to the continuous expansion of space itself. This expansion is described by the theory of the Big Bang, where the universe started as a singularity and has been expanding ever since.
How is the space growing faster than its keyword?
The universe is expanding at a faster rate than the speed of light.
Is light infinite in the universe?
Light is not infinite in the universe. While light travels at a very fast speed, it can still be absorbed or blocked by objects in space. Additionally, the universe itself is constantly expanding, which means that light from distant sources may never reach us.
Is our galaxy orbiting something in space?
Yes, our galaxy, the Milky Way, is part of a group of galaxies called the Local Group, which is moving through space. The Local Group is also part of a larger structure called the Virgo Supercluster, which is itself moving within the expanding universe. So, in a sense, our galaxy is orbiting within the larger cosmic structure of the universe.
Is there is space outside universe to make it expand?
No. It is space itself that is expanding.
What does the universe is expanding mean?
The distance between galaxies is increasing, pretty much in all directions. This suggests that space itself is expanding. We also now know the rate of expansion is in fact increasing.
What is the theory of the big bang?
a theory that says that the universe began with a super-powerful explosion The word "explosion" carries a sense of something of large density expanding from a center point into a region of low density. This is NOT what happened during the Big Bang, despite many popular presentations that imply such an event. The Big Bang was NOT matter expanding from a center point into empty space, it was the expansion of space itself. There was nothing that this space was expanding INTO, it was just expanding.
How is the cosmological motion of a distant galaxy fundamentally different from the motion of an object speeding through space?
The object - planet, meteoroid, comet, spaceship - is traveling THROUGH space; the galaxy is moving away WITH space. That is, the space itself is expanding.
Is the space expanding?
Yes.
If were in space then what is space in what is space expanding into?
No one knows for sure. There are theories, but absolutely none of them can be proved, and I doubt we will ever find out. The universe is expanding firther into what was here before the big bang. Basically, nothing. The universe isn't expanding like a balloon blowing up; the universe is already there, but the objects inside it are spreading out constantly (black holes, stars, galaxies, etc.) The universe isn't expanding; the objects inside are spreading out within it.
Dose space ever end?
NoAnswer:Present thinking is that the Big Bang created space, time and energy/matter. As a consequence at the expanding edge of the Universe there is a region of no space or time.
How could matter move through billions of light years of space in an instant as proposed by the big bang theory?
I don't know about billions of years of space in an instant, but during the big bang space/time itself was expanding at faster than the speed of light. There's a difference between something traveling through space and space itself expanding. In a way, most of the matter in the universe is still more or less where it was 13,5 bln years ago: it's the distances between everywhere and everywhere else that have increased.
Can redshift be detected in objects travelling in space or is it only a feature of space itself expanding?
The red shift is due to the Doppler effect of objects moving away from the observer. (You) So both instances are true.
What percent of space was occupied before the big bang and by the universe now?
The expansion of the Universe should not be thought as if matter expands quickly in an existing space; it is space itself that is expanding. This is a confusing topic; read the Wikipedia article on "metric expansion of space" for a brief introduction.
What theory states that the universe started as a ball of matter which expands and still expanding?
No such cosmological model exists. What you relate e is one description of Big Bang Cosmology (BBC), but that description is WRONG. BBC does NOT postulate that matter is expanding from a small, dense blob into empty space; rather, it describes a Universe in which SPACE ITSELF is growing at a (more or less) steady rate. Matter density is not decreasing in the way that ink density decreases as it expands into a large container of liquid; rather, the density of matter is decreasing because space is expanding as the amount of matter remains the same. Also, space is not expanding into anything, like an exploded material expands into the space around it. Space is just expanding, period. It is difficult to visualize, but the math works out just fine.
What part of space is exspanding?
The only thing expanding is space itself. Imagine the Universe as loaf of raisin bread rising in the oven. As the bread bakes, it’s stretching in all directions – that’s space. But the raisins aren’t growing, they’re just getting carried away from each other as there’s more bread expanding between them.
