Test, Courting Death, and Opening the Portal

Seeing this, Tony couldn't help but curse.

He knew how much energy this thing had.

Since this thing could protect itself, breaking through with just his armor would be impossible.

Tony immediately flew to his building and applied to join Luke's communication channel.

Luke approved his request, and Iron Man's ID appeared on the communication channel. "This guy diverted power from my building to activate the Tesseract. I'll see if I can cut off the power supply. You can stay here and try other methods, anything to stop that thing running."

Luke and Frank looked at each other. Without hesitation, Frank dragged over an unconscious Dr. Selvig and placed his hands on either side of his temples to give him a light electric shock.

Dr. Selvig jerked and abruptly opened his eyes.

Frank: "How do we stop this machine?"

Dr. Selvig's eyes were blank. "It can't be stopped. It'll keep running."
