The main piece of evidence is the redshift of galaxies. In spectroscopy an absorption line that is redshifted indicates that the object is moving away. The farther the object is from the source of observance the faster that object travels in relation to the observer. Almost all galaxies are redshifted as opposed the our local neighborhood, the Andromeda Galaxy for instance is blueshifted because it is heading strait for us. at some point all galaxies will spread so far from each other that they will be going so fast that they reach the speed of light in respect to our position and are never seen again. Another piece of evidence is the fact that their is some warmth in space. Also known as the Cosmic background radiation. Empty Space is around 2.7 degrees kelvin which is the residual heat from the big bang. Had their not have been an explosion with a massive amount of heat and energy and everything simply was, then empty space would be absolute zero. This is the two strongest arguments that support the big bang theory.
What else can I help you with?
What space technologies provided scientists with the best evidence that the universe was created in the Big Bang?
The cosmic microwave background radiation, observed by satellites like the Planck and WMAP, provides strong evidence for the Big Bang theory. This radiation is a remnant from the early universe and supports the idea of an expanding universe from a hot, dense state. Additionally, the observation of redshift in galaxies, studied using telescopes like Hubble, confirms the universe's expansion and supports the Big Bang model.
What describes scientists' best idea about the formation and expansion of the universe?
The Big Bang theory is currently the most widely accepted explanation for the formation and expansion of the universe. It proposes that the universe began as a singularity and has been expanding ever since, with galaxies moving away from each other. This theory is supported by observational evidence, such as the cosmic microwave background radiation and the redshift of distant galaxies.
Is the vacuum of space protection for which the universe is against what it is that its expanding into. just like our world has an atmosphere to protect us against the vacuum.?
Since Time and space seem to have began with the big bang, we simply dont have any way of understanding anything outside of it . the best we can do is say that it appears that the universe is infinite in size and is expanding and accelerating. It looks like there is no end point of the universe.Its hard to accept . But it would be equally hard to accept if there was an end point. Its a great question but no one can really give an intuitive answer, sorry.
What is the best space invention?
It's subjective, but many consider the Hubble Space Telescope as one of the best space inventions. Hubble has provided groundbreaking insights into our universe, including discovering new planets and galaxies, and has revolutionized our understanding of space.
If the universe is everything and scientists say that the universe is expanding what do you think it is expanding into?
The universe does not expand into anywhere, it is expanding everywhere at every moment. The Newtonian view assumes instant communication of the gravitational field. In such a case, one could pose that the kinetic energy of all the matter in the universe speeding off in all directions is equally balanced by gravitational potential energy that would bind all matter together. I suppose this works when the universe was very close to the size of a singularity. However, the force of gravity travels at the limited speed of light by force carriers called gravitons. So by the time a graviton travels from one side of the universe to the particles on the other side, the particles on the other side have traveled even further away. This would make the gravitational force of a particle felt by particles on the other side of the universe seem weaker than in the pure Newtonian scheme. This is like slowly reducing the force of gravity as the universe expands. Wouldn't this have the tendency to make the particles fly apart more rapidly since you are slowly eliminating the opposition of gravity? Or at least it might help ensure that the universe expands forever.If we throw in a particle horizon where some particles have not yet even felt the gravitational force of other particles very distant from us, this could contribute to expansion. The expansion rate is accelerating, however, which requires some new form of energy we currently know next to nothing about. Hence, it is called "dark energy," and accounts for about 75% of the total mass/energy of the universe.It is possible our universe has an event horizon where more and more distant objects are accelerated to the speed where we will never again see them or feel their gravitational force.The term "expanding universe" is not really the best choice of words, because it does imply expansion INTO something. The universe is, by definition, EVERYTHING that exists. So there is nothing outside of the universe however big or small you conceive it to be.The term "expansion" in this case is meant to imply that there is new space being created between sub-atomic particles throughout the universe as a result of the force from a "Big Bang" being (temporarily) stronger than the pull of gravity. Many different theoretical models have been proposed, but the leading model at the present time is known as the "hot inflationary big bang." The evidence for the big bang consists primarily of galactic red shifts, which increase with distance, and the cosmic background radiation which permeates interstellar space--the so-called 3° K microwave temperature.AnswerIt all started with Albert Einstein's theory of relativity. The theory showed that the universe could expand or contract, which opened the door to the Big Bang theory. Hubble's redshift is an indicator that the universe is in equilibrium between the centripetal force of gravity mg= mv^2/R=mMG/R^2 and the centrifugal force due to velocity -mcDel.v= -mcv/R cos(v). Conservation of energy causes these forces to be equal and mV^2/R=mcv/R cos(v) gives:v/c=cos(v)=z the redshift.At v=c the cos(v) is 1 and the mass is traveling radially. The larger the velocity, the larger the redshift v/c = cos(v).The redshift is the consequence of the Conservation of Gravitational Energy or the Boundary of energy or the Limit of energy or the Continuity of energy, etc, in short the first derivative of the energy set to zero, the Invariant Condition.This can be derived by revising Newton's Gravity theory E= -mMG/R by adding the vector energy mcv giving E= -mMG/R + mcv, this is I call the Quaternion Gravitational Energy as it is the sum of a real and vector energy, ala William Rowan Hamilton's Quaternions.Einstein adopted Newton's Gravitational energy and had to add the "cosmological constant to account for the centrifugal force, or the fact the fact the universe had not collapsed due to Newton's Gravity.The so-called "dark energy" is the vector kinetic energy given by mcv. Today we could call the gravitational Energy E= -mu/R + mcv the 4-vector energy momentumP = E + pc= E + mvc.AnswerThe observational evidence is such that we see "stuff" of similar type, at similar distances "back in time", in all the directions we can look. A steady increase in metalicity as we approach our own age, CMBR temperatures similar to the "Hubble shift" and so on. Distant objects are anomalously large, as if they were being magnified by the size of the Universe they were in. This means that the most simple theory that does not require that we are in a "special place", is that all those other places see exactly the same thing we do.This means that there was no pre-existing empty space, the "Big Bang" really was no sort of Bang, and the distance between "super clusters" is increasing with time... what scientists call "gravitationally bound systems".ANSWEROn a vast scale, the space between structures in the Universe is increasing and the rate of increase is accelerating. This is supported by the best available observational evidence. The Universe is a self-contained, unbounded system. There is no external frame of reference to give meaning to the idea of its expanding into some "where."
Which of these facts is the best supporting evidence that the universe is expandingThe stars vary in chemical composition The galaxies can spin to form eddies. The universe is filled with galaxies of?
The best supporting evidence that the universe is expanding is that galaxies are receding from one another, indicating that the universe is expanding over time. This observation is based on the redshift of galaxies, known as Hubble's Law.
Which theory about the universes size best matches the experimental evidence found by astronomers and physicists?
The theory of an expanding universe, known as the Big Bang theory, best matches the experimental evidence found by astronomers and physicists. Evidence such as the cosmic microwave background radiation and the redshift of distant galaxies support the idea that the universe began as a singularity and has been expanding ever since.
What are the best indications that the universe is expanding?
One of the best indications that the universe is expanding is the redshift of light from distant galaxies, which shows that they are moving away from us. Another indication is the cosmic microwave background radiation, which is consistent with an expanding universe. Additionally, observations of the distribution of galaxies and the large-scale structure of the universe support the idea of expansion.
What space technologies provided scientists with the best evidence that the universe was created in the Big Bang?
The cosmic microwave background radiation, observed by satellites like the Planck and WMAP, provides strong evidence for the Big Bang theory.

In 1964 space technologies provided scientists with the best evidence that the universe was created in the Big Bang?
In 1964, the cosmic background radiation was discovered. This provided a strong confirmation for the Big Bang.
Which best dscribes the big bang theory?
Latest theory is that the universe is expanding.
What is the best evidence the universe is still expanding?
The redshift of distant galaxies, and the fact that the degree of redshift depends on the distance between us and those galaxies. What we observe can only be explained by Hubble Expansion.
Why do scientists believe that the universe began with an explosion?
Scientists believe in the Big Bang theory because it is supported by evidence such as the cosmic microwave background radiation and the observed expansion of the universe. These observations suggest that the universe was once in a hot, dense state and has been expanding since its beginning.

What best explains the big bang theory?
The Big Bang Theory present the theoretical premise for the causation, termination, and continuation of an evolutionary expansion of the universe. The Big Bang promotes that the universe is Time bound (or has a finite existence), that the universe is expanding (within the dimensional limits of Space and Time), that the universe is evolving a set amount of matter and energy while it is expanding over time, and that the universe is homogeneous and isotropic with respect to Space and Time.
What describes scientists' best idea about the formation and expansion of the universe?
The Big Bang theory is currently the most widely accepted explanation for the formation and expansion of the universe. It proposes that the universe began as a singularity and has been expanding ever since, with galaxies moving away from each other. This theory is supported by observational evidence, such as the cosmic microwave background radiation and the redshift of distant galaxies.
What best describes how most galaxies generally move?
Galaxies generally move away from one another.
