I get space. What I'm saying is that, assuming we can even hit it, any such rock is moving with too much momentum to be able to change its course. Given any tech that we have. It's easy to underestimate the energy represented by a large asteroid.


How can you be so confidently wrong? Clearly researchers at Lawrence Livermore think it’s a viable approach, or they wouldn’t bother with developing detailed simulations. Why do you think you know more than those researchers?


Stating that I'm "confidently wrong" is rank nonsense, when predicated on an appeal to authority of government-funded low level employees.

"Clearly" their "bother" to develop simulations and conclusions is 100% downstream from government funding to make interesting noise. That doesn't mean that they are wrong. What it does mean is that its nonsense to couch a counter-argument to criticsim in an appeal to authority.


Ok Mr. Expert, what relevant expertise do you have? And what kind of research have you done in the field?

Because surely you have some kind of knowledge to draw on other than a gut feeling if you are going to say professional researches working in the field are wrong, no?


My understanding is that it's nothing to do with momentum and everything to do with mass.


momentum = mass x velocity


sure but what has momentum got to do with adjusting the trajectory in this situation?
