What else can I help you with?
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.
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.
Which best dscribes the big bang theory?
Latest theory is that the universe is expanding.
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 does the big bang theory tell us about current size of the universe?
Not much, unfortunately. We know that our Universe is expanding, and has been for about 13.7 billion years. The problem is, we can only see light from objects that has had time to reach us since the Big Bang. Thus, we can only know about the "observable" universe. How much more of our Universe is outside our present field of vision is still speculative at best.
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.
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.
Do black holes orbit the universe?
Most likely not. The best evidence of the existence of black holes has been found deep within galaxies.
