A. Black holes are extremely common. B. There are more than 100 billion galaxies in the universe. C. The black hole in our galaxy is pulling a gas cloud toward itself. D. Our universe is the product of a black hole in another, older universe. ...
The solutions to Einstein's equations that describe a spinning black hole won't blow up, even when poked or prodded, which means the black holes are stable in a manner of speaking. Source link of Quanta Magazine: https://www.quantamagazine.org/black-holes-finally-proven-mathematically-stable-...
Which statement is a theory, and not a proven fact? (Text A) A.Our universe is the product of a black hole in another, older universe.B.The black hole in our galaxy is pulling a gas cloud toward itself.C.There are more than 100 billion galaxies in the universe.D.Black holes ar...
Second: The source of the idea that black holes might go somewhere is what might be called “mathematically based paranoia”. Often in physics simple experiments will lead to simple math, t...
the net flew from my hand and dropped into the water in a big, useless ball of tangled net. I’d drag the thing back to the surface and untangle it only to have it tangled again after my toss and before it hit the water. The only activity that has proven itself as fruitless as ...
Non-luminous components, such as black holes and intergalactic(星系间的) gas, _5_ up 3.6 percent. The rest is either dark matter, about 23 percent, or dark energy, about 73 percent.Dark matter, sometimes _6_ cold dark matter, has been known for some time. Only recently have researchers...
Other researchers claim that the reason ghosts haven't been proven to exist is that we simply don't have the right technology to find or detect the spirit world. But this, too, can't be correct: Either ghosts exist and appear in our ordinary physical world (and can therefore be detected...
Given the under-resolved nature of current simulations, it is not yet proven that high-yield r -process channels are favored. However, it has become clear that previous claims ruling out NS–NS/BH–NS 123 3 Page 8 of 59 B.D. Metzger mergers with closed-box chemical evolution models (...
We show that, for any positive integersnandm, if a setSRmintersects everym− 1 dimensional affine hyperplane inRmin exactlynpoints, thenSis not an Fσset. This gives a natural extension to results of Khalid Bouhjar, Jan J. Dijkstra, and R. Daniel Mauldin, who have proven this result ...
(Historically, waiting too long has proven disastrous.) But one good thing about Canada is that the government is willing to fund a suitable legal defense for indigent people – including Bill Whatcott, who has an excellent law firm representing him. Compare that to the U.S., where the ...
