"Horizon" Project Poltergeist altyazı (158109)

1
00:00:02,587 --> 00:00:07,169
Something very strange is happening to you right now.

2
00:00:09,639 --> 00:00:14,084
A swarm of ghosts is flowing straight through your body.

3
00:00:16,701 --> 00:00:21,569
There are something like a hundred trillion of them,
streaming through each of us, every second,

4
00:00:21,570 --> 00:00:23,845
every second a hundred trillion.

5
00:00:25,593 --> 00:00:29,452
Most of them pass through without doing anything, so this was ghostly

6
00:00:30,202 --> 00:00:32,032
or poltergeist-like.

7
00:00:34,178 --> 00:00:39,503
Catching these ghosts was one of the
greatest challenges scientists have ever faced.

8
00:00:42,354 --> 00:00:45,732
When you think about it, it’s almost unbelievable

9
00:00:45,733 --> 00:00:50,612
what we were doing and I’m glad we, we didn’t think
about it too carefully when we were doing it.

10
00:00:52,349 --> 00:00:57,475
Now experiments have revealed that they’re
even stranger than anyone thought.

11
00:00:57,710 --> 00:01:03,493
Not only have they solved several mysteries,
but they’re our parents.

12
00:01:05,981 --> 00:01:09,828
Could the tiny particles that are passing through you right now

13
00:01:09,957 --> 00:01:12,667
be the very reason we all exist?

14
00:01:19,917 --> 00:01:21,735
They’re here.

15
00:01:37,970 --> 00:01:42,334
John Bahcall and Ray Davis have been friends for nearly half a century.

16
00:01:48,223 --> 00:01:54,451
For most of that time these two men have been at
the heart of the biggest puzzle in particle physics.

17
00:01:55,542 --> 00:01:56,704
Turn some more.

18
00:01:56,938 --> 00:02:01,607
It all began forty years ago with a daring underground experiment.

19
00:02:07,132 --> 00:02:09,665
Ray Davis had tunnelled deep into the earth

20
00:02:09,666 --> 00:02:13,477
to build a trap for the most elusive particle in nature.

21
00:02:16,597 --> 00:02:20,421
It was an experiment which few thought could ever succeed.

22
00:02:22,017 --> 00:02:27,237
He set out to do something which sounds totally impossible.

23
00:02:27,624 --> 00:02:30,580
And it produced a result which no one could believe.

24
00:02:30,732 --> 00:02:35,025
