Of course, is the gullible factor in believing the scientists, or going against them? Remember that way back 500 years ago science was very different than it is today. Most of the scientific technology that we use today, would have gotten us executed 500 years ago if we had even talked about it back then.

The fact that we have advancements these days, that were not seen 500 years ago, suggests that we are doing something right. However, people are still people. Scientists often like to protect their pet projects to the tune of denouncing everything else if necessary. It's just like the Church did back 500 years ago.

The point? Let's keep a very open mind. Bending space so that we can travel to other worlds almost like walking through a doorway, might be far easier than scientists are willing to admit to themselves. Teleportation to Mars might be far easier than rocket flight there. If we don't keep an open mind, we will not even look for new ideas.

If people have changed in the last 500 years, the change is not for the better. People are getting "dumber" even as the technology is growing.
