00:04.0
00:05.5
Let's say the surface of this water
00:05.6
00:07.5
represents our universe
00:08.0
00:12.0
Everything we can see and touch and feel represent it right here
00:12.1
00:15.5
on the surface. And let's say this is us.
00:15.6
00:17.0
Notice that we are stuck on the surface
00:17.1
00:18.6
of this water.
00:21.1
00:23.0
So we cannot leave our universe.
00:23.1
00:27.6
That's us floating on the fabric of space and time
00:28.0
00:31.0
However, there could be another universe
00:31.1
00:34.0
located at the bottom of this water.
00:34.1
00:38.0
What we need is a bridge connecting 2 universes.
00:38.1
00:43.0
Most physicists believe that nature allows parallel universes
00:43.9
00:47.0
to exist just like 2 separated planes of water
00:48.0
00:49.0
But is there a way to connect 2 planes
00:49.1
00:52.0
that are completely isolated from one another?
00:55.0
00:58.0
Water can be distorted into a whirlpool
00:58.1
01:00.0
that connects the top and the bottom.
01:00.1
01:03.0
Physicists like Michio have discovered that
01:03.1
01:07.0
just like a whirlpool, space itself
01:07.1
01:09.0
can bend and distort to form a pathway
01:09.1
01:11.0
between 2 parallel universes.
01:11.1
01:16.0
A pathway known as a wormhole.
01:16.1
01:17.0
Now wormhole is a portal
01:17.1
01:20.0
that allows you to back and forth between 2 worlds.
01:21.0
01:22.0
But they are potentially unstable.
01:22.1
01:25.0
To stabilize that we need a new substance called
01:25.1
01:31.0
negative energy.
01:32.0
01:35.0
Just like an oil-based solution pushes apart water
01:35.1
01:39.0
negative energy would push apart space itself.
01:39.1
01:43.0
You see, this negative energy is anti-gravitational.
01:43.1
01:45.0
Positive energy wants to collapse the hole.
01:45.3
01:48.0
Negative energy wants to keep it afloat.
01:48.1
01:50.0
However, with enough negative energy,
01:50.1
01:57.0
you may be able to go right through the wormhole.
01:58.1
01:59.8
Our entire civilization could move from one universe
01:59.9
02:05.0
to another through a wormhole
