Hypothetical space portal question, if Earth scientist did locate one, would they attempt to open it?

Let’s say for sake of this question, scientist here on Earth knows there is a space portal out there, location is irrelevant. By some means, also irrelevant, they know the location and existence of the portal came from communications within or through the portal. The scientists have no clue to the nature of who sent the info, just that it was sent, and they decoded it. Would scientist here attempt to open the portal not knowing really what or who lies on the other side?
