• we will never travel through time - yes, as long as we do not know what the time is and how it is coupled with other forces. Actually, we do travel, but it is a one way train without controls. From the past to the Future.
• we will never travel to the stars - no we will. What Columbus and Magellan did in their time was as techically difficult and dangerous as travel to stars today. Technology is there, but practical outcome is not. When our spacecraft of today - bamboo rafts - will be replaced by sail ships, we'll go. Adventurism, curiosity and lust for exploration always took upper hand.
• cold fusion will never work - it will not just because there is no such phenomenon like cold fusion.

No, not the same at all. Man was created with the ability to make big boats, like the ark, and spend long enough amounts of time in them that ocean currents alone would take you all over the world. Nothing even remotely like this is true about space travel. Think of the requirements to travel 25 trillion miles!

cold fusion will never work - it will not just because there is no such phenomenon like cold fusion.

We are in agreement here.
