What are advantages HST?
the advantages of the HST is that they can see deeper into the universe and see clearer past the atmosphere compared to other land based telescopes.
What is uniformtarianism?
Typically quoted along with "the past is the key to the present" (or visa versa), this concept is the idea that geologic processes occuring now have always occurred throughout earths history (although NOT always at the same rate or intensity). Some examples: we see volcanoes erupting now, so there must have been volcanoes erupting in the past. We see animals go extinct now, so therefore animals must have gone extinct in the past. We see erosion causing sand along a beach now, so therefore sand in the geologic record must have formed at beaches. We see climate change now, so climate must have changed in the past. And so on.
What is another term for universe?
that portion of the universe that we can see in principle, given the finite age of the universe
How does knowing how a star forms help an astronomer study the origins of the universe?
Quasars are the bright centers of young galaxies. Many quasars we can view today existed billions of years ago, and their light is just now reaching us. They are a snapshot of the past, and tell us about how galaxies formed. From wikipedia: "While there was initially some controversy over the nature of these objects, there is now a scientific consensus that a quasar is a compact halo of matter surrounding the central supermassive black hole of a young galaxy."
Has the universe been the same since the big bang?
No - That is a premise of the Steady State Theory. Rather the universe has been undergoing an evolutionary expansion in which the actual environmental state of the universe is ever changing. The interpretation of observational evidence from the detection of deep space radiations have provided us a window into the past; wherein the universe of the CMBR barrier demonstrates that the universe was once just a soup of hot dense plasma. (See related question below for more information.)
What is the steady state Universe model?
A model describing the Universe as static and not changing. According to this model the Universe always existed and always will, and it was in the past the same way we see it today.
What part of universe contains information about past?
The distant universe is seen as it was when the light we see now left it, this is as much as 13 to 15 billion years ago.
How did the universe started?
Science has advanced to the point where we can infer something about the entire universe. This has been a great challenge considering how unimaginably vast the universe is. The countless stars you see in the darkest sky constitute merely 3000 neighbors out of about 300,000,000,000 stars in our galaxy, and as many as 100,000,000,000 galaxies exist in the universe. Humans have always wondered: Has the universe always existed like we see it now, or did it somehow start all of a sudden? In the beginning of this past century, we found out in amazement that the entire universe is expanding. This led physicists to deduce that the universe started out in the finite past with a minuscule size. Realizing that the universe had a beginning, and awed by its vastness and its creations, people have asked: How did the universe begin? After all, we are here to be amazed by it because the universe eventually created lives like us. Now, after decades of observing and thinking, we have come to answer confidently the question of the origin of our universe... with what is known as the "big bang".
Is it possible to find information about past in universe?
Yes. That's what telescopes allow (and require) that you do. The reason is that the speed of light is finite, so you never see "now", but what happened in the past.
What are advantages HST?
the advantages of the HST is that they can see deeper into the universe and see clearer past the atmosphere compared to other land based telescopes.
I am in the past never in the future I do not exist but existed once I saw what you saw and that's all I'll ever see What am I?
an idea
What existed when dinosaurs existed?
Bacteria, viruses, algae, ferns, trees much like the ones we see now, turtles, fish, birds (latest thinking is that they existed alongside dinosaurs)... worms, shelled sea life..
What can we see but God cannot see?
Past sins that have been forgiven, and now covered by Christ's blood.
How far has a satellite gone in the universe?
Right now, the farthest spacecraft is the Voyagers which were launched in the 70's. But, they are only just out of our solar system. The universe as we know right now, is infinite. But, Hubble can see things that are unbelievable distances away.
Why people are becoming more cruel?
People have always been cruel. Murder, kidnap and torture have ALWAYS existed everywhere across the world. The difference now is that TV and internet allow us to INSTANTLY see acts of cruelty EVERYWHERE in the world that they happen. This was not so in the past.
When do you use past tenses of see go and begin?
When you are talking about something that happened in the past and is now finished - past simple. see -- I saw Jack last night. go -- We went to the cinema. begin -- The movie began on time.
When looking at stars do you see the star or its light?
You see the light it gave off in the past, not now. The star you see now could have died years ago, but its light is still trying to reach earth.
