Because they do not come from experiment backed studies but fantasy claims.So you will disregard the professor because he is a science popularizer ? How are his ideas not respectable ?

On Elon Musk, let him do it first. He has promised a lot more ridiculous ideas [1][2] and he gets away with that somehow. More importantly, even we managed to land on Mars as a two way mission then how does that equate to colonizing it? We landed on Moon 1969 where are the Moon colonies? Lastly, I suggest you to not derive scientific ideas from fiction books, that's a bad way to learn serious science as Sci-Fi authors do not usually follow the real science when making up their stories.1. You say Mars cannot be terraformed but do you also say that it is unlivable in the next 15 years ? SpaceX has said it will land humans on Mars by 2026. And you should read Kim Stanley Robinson's Mars sci-fibook trilogy ( Red Mars, Green Mars, Blue Mars ) which is about the technological, political, socio-economic and terraforming elements of Mars. These books are called the textbooks for human settlement of Mars, though I don't see why the author struggled so much over developing a socio-economic theory in this story.
2. About very high speed space travel please read of this post of mine about a under-development part-electric part-mechanical propulsion system called MEGA drive which technically can propel close to light speed.
Your second link is simply unproved theory.
[1] Elon Musk's Loop is a Bizarrely Stupid Idea - YouTubeThe effect is controversial because within mainstream physics the underlying model proposed for it appears to be faulty, resulting in violations of energy conservation as well as momentum conservation.[3] Woodward and his associates have claimed since the 1990s to have successfully measured forces at levels great enough for practical use and also claim to be working on the development of a practical prototype thruster. No practical working devices have been publicly demonstrated, and other experiments have failed to corroborate these claims.[4]
Woodward's work with Hal Fearn on their Mach-effect thruster earned them a $125,000 grant from NASA's Innovative Advanced Concepts program in 2017, and a second grant of $500,000 in 2018. Through variations in the device's configurations, they were able to achieve a thrust of more than 100 micronewtons. The Naval Research Laboratory in Maryland will test the thruster when its lab resumes normal operations as the COVID-19 pandemic eases.[5]
