Böse Kinder gibt es nicht. Kaum auf der Welt, haben sie schon ein feines Gespür für Gut und Böse. In Langzeitstudien konnte Paul Bloom beobachten, wie die ganz Kleinen bereits Gefühle wie Mitleid, Schuld und Scham zeigen, gutes Verhalten bei anderen belohnen und schlechtes bestrafen. Der renommierte Entwicklungspsychologe der Yale University führt aus, wie sich das angeborene Mitgefühl weiterentwickelt und wie Eltern und Erzieher die natürlichen Anlagen der Kinder zum Guten und ihren Sinn für Gerechtigkeit zur Entfaltung bringen können.

“Es sind Widersprüche (..), denen Paul Bloom nachgeht. Er hat kein Wohlfühlbuch geschrieben, das einen geradlinigen Weg vom Moralsinn des Babys hin zu einem Immanuel Kant oder John Stuart Mill aufzeigt. Denn trotz ihrer biologischen Basis sei Moral keine Selbstverständlichkeit, betont der Psychologe.”
Deutschlandradio Kutlur (online), 08.06.2015
“‘Jedes Kind kennt Gut und Böse’ zieht ein vorläufiges Fazit eines jungen Forschusfeldes, das noch viele offene Fragen und widersprüchliche Ergebnisse beinhaltet.”

Er schreibt häufig u.a. für die Zeitschriften: “The New York Times Magazine”, “The Atlantic”, “Science”, “Slate”, “The Best American Science Writing”. Bloom lebt mit seiner Frau und zwei Söhnen in New Haven, Connecticut, USA.
Astrophysicist, cosmologist and Nobel Prize winner George Smoot studies the cosmic microwave background radiation — the afterglow of the Big Bang. His pioneering research into deep space and time is uncovering the structure of the universe itself. He has also made a cameo appearance (as himself) in an episode of the ‘Big Bang Theory.’
George Smoot looks into the farthest reaches of space to the oldest objects in the known universe: fluctuations in the remnants of creation. Using data collected from satellites such as COBE and WMAP, scanning the cosmic microwave background radiation (a relic of the heat unleashed after the Big Bang), he probes the shape of the universe. In 1992 he and his Berkeley team discovered that the universe, once thought to be smooth and uniform at the largest scale, is actually anisotropic — or varied and lumpy. Smoot continues to investigate of the structure of the universe at the University of California at Berkeley, mapping billions of galaxies and filaments of dark matter in hope of uncovering the secrets of the universe’s origins.
What may have started as a science fiction speculation—that perhaps the universe as we know it is a computer simulation—has become a serious line of theoretical and experimental investigation among physicists, astrophysicists, and philosophers.
Neil deGrasse Tyson, Frederick P. Rose Director of the Hayden Planetarium, hosts and moderates a panel of experts in a lively discussion about the merits and shortcomings of this provocative and revolutionary idea.

00:00:00,000 –> 00:00:04,264
What would happen to you if a black hole the size of a coin suddenly appeared near you?
3
00:00:04,836 –> 00:00:05,887
Short answer: you’d die.
4
00:00:06,351 –> 00:00:07,424
Long answer: it depends.
5
00:00:08,081 –> 00:00:09,169
Is it a black hole with
the mass of a coin,
6
00:00:09,963 –> 00:00:11,017
or is it as wide as a coin?
7
00:00:11,503 –> 00:00:14,549
Suppose a US nickel with
the mass of about 5 grams
8
00:00:14,963 –> 00:00:16,975
magically collapsed into a black hole.
9
00:00:17,083 –> 00:00:20,139
This black hole would have a radius
of about 10 to the power of −30 meters.
10
00:00:20,645 –> 00:00:24,727
By comparison, a hydrogen atom is about
10 to the power of −11 meters.
11
00:00:25,465 –> 00:00:27,564
So the black hole compared
to an atom is as small as
12
00:00:28,455 –> 00:00:29,531
an atom compared to the Sun.
13
00:00:30,215 –> 00:00:31,282
Unimaginably small!
14
00:00:31,885 –> 00:00:34,964
And a small black hole would also have
an unimaginably short lifetime
15
00:00:35,675 –> 00:00:36,736
to decay by Hawking radiation.
16
00:00:37,285 –> 00:00:42,302
It would radiate away what little mass it
has in 10 to the power of −23 seconds.
17
00:00:42,455 –> 00:00:46,532
Its 5 grams of mass will be converted
to 450 terajoules of energy,
18
00:00:47,225 –> 00:00:50,246
which will lead to an explosion
roughly 3 times bigger than
19
00:00:50,246 –> 00:00:53,283
the atomic bombs dropped on
Hiroshima and Nagasaki combined.
20
00:00:53,627 –> 00:00:54,674
In this case, you die.
21
00:00:55,097 –> 00:00:56,195
You also lose the coin.
22
00:00:57,092 –> 00:00:59,170
If the black hole had the
diameter of a common coin,
23
00:00:59,088 –> 00:01:01,341
then it would be considerably
more massive.
24
00:01:02,133 –> 00:01:05,265
In fact, a black hole with
the diameter of a nickel
25
00:01:05,265 –> 00:01:07,286
would be slightly more
massive than the Earth.
26
00:01:07,475 –> 00:01:10,547
It would have a surface gravity
a billion billion times greater
27
00:01:11,195 –> 00:01:12,202
than our planet currently does.
28
00:01:12,895 –> 00:01:14,953
Its tidal forces on you would be so strong
29
00:01:15,483 –> 00:01:17,567
that they’d rip your
individual cells apart.
30
00:01:18,323 –> 00:01:22,330
The black hole would consume you before
you even realized what’s happening.
31
00:01:22,393 –> 00:01:24,419
Although the laws of gravity
are still the same,
32
00:01:24,657 –> 00:01:27,692
the phenomenon of gravity that you’d
experience would be very different
33
00:01:28,007 –> 00:01:29,091
around such dense objects.
34
00:01:29,087 –> 00:01:30,169
The range of the gravitational attraction
35
00:01:31,702 –> 00:01:33,729
extends over the entire
observable universe,
36
00:01:33,972 –> 00:01:36,974
with gravity getting weaker the farther
away you are from something.
37
00:01:37,172 –> 00:01:41,221
On Earth right now, your head and your
toes are approximately the same distance
38
00:01:41,662 –> 00:01:42,708
from the center of our planet.
39
00:01:43,122 –> 00:01:45,179
But if you stood on
a nickel-sized black hole,
40
00:01:45,692 –> 00:01:47,771
your feet would be hundreds
of times closer to the center,
41
00:01:48,482 –> 00:01:51,556
and the gravitational force would be
tens of thousands of times as large
42
00:01:52,231 –> 00:01:55,276
as the force on your head and
rip you into a billion pieces.
43
00:01:55,681 –> 00:01:57,730
But the black hole wouldn’t
stop with just you.
44
00:01:58,171 –> 00:02:01,200
The black hole is now a
dominant gravitational piece
45
00:02:01,461 –> 00:02:03,520
of the
Earth–Moon–Black-Hole-of-Death system.
46
00:02:04,051 –> 00:02:07,122
You might think that the black hole would
sink towards the center of the planet
47
00:02:07,761 –> 00:02:09,795
and consume it from the inside out.
48
00:02:10,101 –> 00:02:14,154
In fact, the Earth also moves up onto the black hole and begins to bob around,
49
00:02:14,631 –> 00:02:15,638
as if it were orbiting the black hole,
50
00:02:16,331 –> 00:02:18,405
all while having swathes of mass eaten with each pass,
51
00:02:19,071 –> 00:02:20,133
which is much more creepy.
52
00:02:21,049 –> 00:02:23,100
As the Earth is eaten up from the inside,
53
00:02:23,559 –> 00:02:25,613
it collapses into a
scattered disk of hot rock,
54
00:02:26,099 –> 00:02:28,125
surrounding the black hole
in a tight orbit.
55
00:02:28,359 –> 00:02:31,364
The black hole slowly doubles its mass
by the time it’s done feeding.
56
00:02:31,859 –> 00:02:33,954
The Moon’s orbit is now highly elliptical.
57
00:02:34,809 –> 00:02:36,857
The effects on the Solar system
are awesome—
58
00:02:37,289 –> 00:02:41,289
in the Biblical sense of awesome,
which means terrifying.
59
00:02:41,298 –> 00:02:44,374
Tidal forces from the black hole would
probably disrupt the near-Earth asteroids,
60
00:02:45,058 –> 00:02:47,092
maybe even parts of the asteroid belt,
61
00:02:47,042 –> 00:02:49,084
sending rocks careening
through the Solar system.
62
00:02:49,847 –> 00:02:51,930
Bombardment and impacts
may become commonplace
63
00:02:52,677 –> 00:02:53,725
for the next few million years.
64
00:02:54,157 –> 00:02:58,157
The planets are slightly perturbed, but
stay approximately in the same orbit.
65
00:02:58,157 –> 00:03:00,164
The black hole we used
to call Earth will now
66
00:03:00,857 –> 00:03:02,862
continue on orbiting
the Sun in the Earth’s place.
67
00:03:03,363 –> 00:03:05,429
In this case, you also die.
