Until 1970's when sufficient evidence has accumulated that dark matter could no longer be ignored.

Proof?

They create shelter from the wind.

They accumulate the solar energy.

Where is this evidence ?

Have you any proof?

How do you know?

Prove it.

Prove it.

In moments, we'll be at siren strength.

LlNDSTROM Yes, yes. Tell him Dr. Lindstrom called.

One individual can make a difference

We got him

You got any proof?

Evidence...!
