Cosmic anomaly exposes interdimensional breach

Tyler presents alarming evidence of a scientist’s vanishing alongside erratic cosmic radiation readings that defy known physics. His x-ray plates reveal faster-than-light phenomena and an ominous, faceless distortion. After reporting his findings to the Doctor, Tyler prepares to develop a critical new plate—only for it to reveal a terrifying antimatter entity’s arrival. His sudden disappearance and the crackling emergence of energy mark the moment the team recognizes an existential threat beyond conventional science.

Key Dialogue

"DOCTOR: Thank you. Well, it's travelling faster than light."
"TYLER: Yes. And it can't, can it. I don't know what to make of it. It's come all that way, through millions of star systems. It must have been directed, and it must have been directed at us. Now why?"
"DOCTOR: Why indeed, Professor Tyler, why indeed."
