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.
What forces cause this expansion?
The expansion of the universe is primarily driven by dark energy, a mysterious force that permeates space and causes it to stretch at an accelerating rate. This expansion is also influenced by the distribution of matter and energy throughout the universe, which determines the overall shape and evolution of the cosmos.
How can you tell the universe is accelerating away from a center and not accelerating toward a center?
A thought experiment: A mile high unlit black box is setting on earth. Three lit rocks are dropped from the top a few seconds apart with a sleeping astronomer (who knows nothing about his situation) on the second rock. Astronomer wakes up sees rocks 1 and 3 accelerating away from him and assumes his universe is expanding.
How does the density of galaxies change as the universe expands?
As the universe expands, the density of galaxies decreases. This is because the space between galaxies increases as the universe expands, leading to a lower concentration of galaxies in a given volume of space.
Do gases expand to fill whatever space is available to them?
Yes, gases expand to fill the container or space in which they are contained. This is due to the random motion of gas particles, which allows them to occupy all available space within the container.
Is the universe everything?
the universe can not be everything because there has to be space for it to expand into
Is there is space outside universe to make it expand?
No. It is space itself that is expanding.
Is it possible that there is no end OR beginning to space?
Because of the scientific theory of the Big Bang, the universe expanded in all direction still continues to expand faster than the speed of light
Is space formed by dark energy?
We do not know. Certainly current THEORIES suggest that dark energy is causing the universe to expand at a faster and faster rate. Its existence is postulated to explain why we can observe that the universe is expanding at an accelerating rate. However, we do not know what dark enery is (if it exists).
What did most scientists think about how the universe began?
The generally accepted model is called the "Big Bang". It means that all the matter and energy of the Universe was in a tiny space, some 13.8 billion years ago or so, at a tremendously high temperature and density. From there, it started to expand; currently, the Universe continues expanding, and will probably continue to expand forever.
Why does space keep going and going and never stops?
Space is constantly expanding because of the force of dark energy, causing galaxies to move away from each other. There is no boundary or edge to the universe, so it appears to go on forever. Gravity from matter in the universe acts as a brake on this expansion, but dark energy seems to be winning, pushing the universe to expand at an accelerating rate.
How far does space reach?
Space is infinite and ever-expanding. There is no clear boundary or end to space, as it continues to expand in all directions. The observable universe is estimated to be about 93 billion light-years in diameter, but beyond that lies even more uncharted territory.
What was distributed as the universe expanded in the Big Bang theory?
As the universe expanded (and continues to expand) per the Big Bang theory, matter and energy also expanded or could be said to have been distributed or scattered from its initial state, although not in a perfectly uniform fashion, leading to the large scale structures in the universe visible today. Advanced theories indicate that intrinsic properties of the universe also began to expand, such as space itself.
What happens when outer space runs out of outer space to expand into?
In theory, it can't. Astronomers consider time and space to be different sides of the same function - they call it "timespace". As long as time continues, space will continue to expand.
A sentence with the word universe?
You are captain of your own universe. The Universe continues to get smaller as we learn more about space.
Facts about the big bang?
I can only think of these: The universe is 13.7 billion years old. - All the matter in the universe used to be very close together (very dense). - The universe used to be a very uniform cloud of energy/mass despite it being very clumpy today (galaxies being those clumps). - Space began to expand and pushed matter apart. - The expansion of space is accelerating. - In the beginning the universe was so hot all the universal forces (gravitation, electromagnetism, etc.) were one force. -The accelerating expansion of the universe will one day spread galaxies so far apart we will not be able to see them because the light leaving them will constantly have new space created in front of it.
Into what space can your expanding universe expand into if it is already infinite?
You're correct in pointing out that the Universe fills all space that there is. Following from that fact, it becomes obvious that in order for the Universe to expand, it has to be space that expands. You have to remember that "infinity" is not a definite number, but a concept or series of concepts. "Infinity plus one" is still "infinity" (maybe). It's not any easy concept.
