The assumptions are not quite correct.Scientists CAN see black holes. In fact, black holes are among the brightest objects in the Universe. Of course, light can't escape from WITHIN the black hole; rather, what we see is the accretion disk.
Also, scientists are PRETTY SURE that black holes are real.
As to why it is important: Black holes are fascinating objects by themselves. They also seem to play an important role in galaxy formation.
Electromagnetic radiation (EMR) is important when studying photosynthesis because without sunlight emitting EMR photosynthesis cannot occur.
Study of... without knowing what the scientists are studying, you cannot know exactly what instruments they are using.
the importance of studying science,tech,and society is so you know what you can do in nature and what you cannot do.
Without it you cannot tell for certain how far things are away from you. This can be very dangerous.
snakes cannot try to be poisonous they can only be born that way unless scientists run tests on it and improve or remove certain parts of the snake
Scientists cannot be certain about how life began on earth because there is no evidence on where the first living thing came from.
Scientists want to understand the universe in which we live, and light is clearly an important part of our universe, and is worth understanding. As it turns out, there are many very important practical applications to an understanding of light, since there are technologies such as lasers, as well as microscopes, photographic cameras, and so forth, which cannot be built without an understanding of light. But the desire to understand is what comes first, then the practical applications follow.
the five importance of studying science is 1.its important becoz..we can use it in are daily lives 2.we can measure our examples our one glass of water.. a full bucket of water..if we do not study science we cannot estimate or measure of liquid and etc..
Yes there are online courses for studying for the SAT. No you cannot take them at conventional times. Your best option is to commit to a study schedule and work on pacing.
Scientists cannot warn people yet with an very accurate statement. Scientists are currently studying seismic activity. The best estimate would be to study seismic gaps, foreshocks, changes in rocks, and more. It might give them a possible location and time of the future earthquake. They hope to soon find ways to warn people, but for now they just have to try their best.
Scientists must rely on estimates when they cannot obtain exact numbers.
Scientists cannot predict when a volcano will next erupt.
