Thestrong gravity of a black hol pullsthings. The black hole “eats" these things. Black holes can even "eatlight That's why a black hole looks "black"Q:If black holes are "black" how do scientists know they are there?A: 4. But we can see how theirstrong gravity works on the ...

Does antimatter have gravity? How does antimatter work? Is the concept of antimatter a theory? Have scientists created antimatter? Where is antimatter found? How was antimatter discovered? How do matter and antimatter differ? Can antimatter be used as an energy source? Does dark matter exist? Do...
What do NASA scientists want to learn about? A. How mice imitate human behavior in space. B. How low gravity affects the human body. C. How mice interact in a new environment.
What else do you think scientists will find at thecenter of our galaxy? How many more black holes doyou think are out there?Astronomers(天文学家) say the center of ourgalaxy has plenty of strange, super gravity objects(超重力物体). For years, scientists believed that circlingthe center of...
Scientists studied 105 students between the ages of eight and nine. 35 trained dogs and their trainers also took part in the test. The children were divided into 3groups. The students in the first group spent 20 minutes with a dog and its trainer. They watched the trained dogs perform and...
This said, this approach, in part, because its author is primarily a QCD (quantum chromodynamics) physicist, rather than an astrophysicist or GR researcher, hasn't received much attention from other scientists in field: few other scientists have built on it, and no one has seriously examined ...
