How does the diameter of the disk of Milky Way Galaxy
|| || || || || || || || || || ||
compare to its thickness? || || ||
The diameter is about 10 times as great as the thickness.
|| || || || || || || || || ||
The diameter is about 100 times as great as the
|| || || || || || || || || ||
thickness.
The diameter and thickness are roughly equal.
|| || || || || ||
The diameter is about 100,000 times as great as the
|| || || || || || || || || ||
thickness. - CORRECT ANSWER(S)✔✔The diameter is || || || || || ||
about 100 times as great as the thickness.
|| || || || || || ||
Current estimates place the age of the universe at about
|| || || || || || || || || ||
________.
10 billion years

|| || || || || || ||
Which of statement below about black holes is not true?
|| || || || || || || || ||
If you watch someone else fall into a black hole, you will
|| || || || || || || || || || || ||
never see him (or her) cross the event horizon; you'll only
|| || || || || || || || || ||
see him fade from view as the light he emits or reflects
|| || || || || || || || || || || || ||
becomes more and more redshifted. || || || ||
Although we are not 100% certain that black holes exist,
|| || || || || || || || || ||
we have strong observational evidence in favor of their
|| || || || || || || || ||
existence.
If you fell into a black hole, you would experience time to
|| || || || || || || || || || || ||
be running normally as you plunged rapidly across the
|| || || || || || || || ||
event horizon. ||
A spaceship passing near a 10 solar mass black hole is
|| || || || || || || || || || ||
much more likely to be destroyed than a spaceship
|| || || || || || || || ||
passing at the same distance from the center of a 10
|| || || || || || || || || || ||
solar mass main-sequence star. - CORRECT
|| || || || || ||
ANSWER(S)✔✔A spaceship passing near a 10 solar mass || || || || || || || ||
black hole is much more likely to be destroyed than a
