Describe Two ways scientists calculate the age of the universe?
By measuring the rate of expansion of the universe using the Hubble constant and then calculating backwards to determine when the universe started expanding, scientists can estimate the age of the universe. By studying the cosmic microwave background radiation left over from the Big Bang, scientists can infer the age of the universe by measuring the temperature fluctuations and using them to determine the time since the universe began.
How big do astronomers estimate the universe to be?
There is no end. They Universe is always expanding due to the big bang. ----------------------------------------------------------------------------------------- No, the Universe actually closes in on itself. If you left from here in any direction, and you went far enough and fast enough, you would arrive right back here. In any case, the Universe does not have any boundaries.
When did universe begin where is the end?
We have no way of knowing the answer. Will the universe ever end at all? Again, we don't know. Right now, we suspect that the universe may expand forever; we cannot "see" enough mass to cause the expansion to slow down. But then, we can't see enough mass to keep the Milky Way together; it is spinning entirely too quickly for the mass that we know about to generate enough gravity. Some scientists have postulated some form of "dark matter", and perhaps even a corollary "dark energy" to account for the mass we cannot see. If there is enough (and if it exists at all!) then the universe may, perhaps, slow its expansion and collapse into itself, at some unimaginably distant date in the future. But we're guessing, and scientists try not to guess. Much.
How could you combine the following two questions into one question Ex- Who KnowsDoes the universe have nine planets Is it - Who Knows if the universe has nine planets or?
Those are both poorly worded versions of the same question. The question should read:"Does the universe have nine planets?"And the answer is:"No. The Universe has trillions and trillions of planets, but our solar system has eight planets."
How does gravity affect all matter in the universe?
Any two objects attract one another.
What are the two ways the universe might end?
One way is Illuminati taking over, the other would definitely be a zombie apocalypse
End of the universe?
We know NOTHING about the "end of the universe". We don't know if the universe WILL end, or what might cause this to happen, or what would come "after" the end of the universe, or even if the phrase "after the end of the universe" has any meaning at all. There are some pretend "scientists" who can tell you, in amazing detail, what the "end of the universe" might look like. But no two of these actually agree, and all their guesses are based on shaky mathematical models which may (or may not!) have any relevance or accuracy. Science is, to a very large degree, the study of our ignorance. We try to learn a little bit, but for every new fact we discover ten new questions, so our ignorance grows faster than our knowledge.
In what ways might two electromagnetic waves differ?
In frequency or wavelength.

What are the different kinds of theories of universe?
One, that the universe is infinite, thus meaning it continues forever. Two, that the universe is finite (has an end) and is expanding but gradually reducing speed and in the future may start to reverse and contract. In the end compacting into an immense power and then exploding. A cycle. Big bang.
What are two ways in which workers might arrange the time they spend working?

What are two ways congress tried to end apartheid in south Africa?

What are two ways that the expansion of urban areas might be harmful to nearby ecosystems?
Two ways that the expansion of urban areas might be harmful to nearby ecosystems is that is could destroy animal's natural habitats and it could also pollute the environment.
When will the universe come to a end?
I would suggest you ask one or two questions about one topic, not 10 at a time. Also, if you have so many questions about one topic, you can look it up in the Wikipedia. In this case, "End of the Universe" will redirect you to "Ultimate fate of the Universe", a very informative article. Then you might come back here and ask a few more specific questions. Please note that not all details about the end of the Universe are known for sure. This is still an area of active research. In general, the Universe is expected to continue expanding indefinitely. Therefore, no very specific date for the end of the Universe can be given. However, eventually there will be less and less available energy, so there will come a time when the Universe will not be able to support life. Not just "life as we know it", but any life - since it seems fairly safe to assume that all types of life will have one thing in common: they need free energy.
What is a circuit that goes more than one way?
A circuit can only go two ways. They are from the beginning to the end or from the end to the beginning.
What is two ways chemists study the universe?
Chemists study the universe by analyzing the composition of extraterrestrial objects like meteorites and comets. They also use spectroscopy to analyze light from stars and planets to determine their chemical makeup.
What does a neutron star become after it dies?
It's possible that two neutron stars could collide; if that happened, the combined mass & gravitational attraction might be enough to collapse the combined object into a black hole. Otherwise, it will be a neutron star until the end of the universe.
