Okay, to summarize this discussion:
A radar would not be able to detect particles such as grains of sand or
small rocks. Therefore I suppose you need a powerful laser in the front of
the spacecraft to heat them and break them into molecules or plasma. It
would have to be turned on at all times bec

Hi,
At half the speed of light, the kinetic energy of a Hydrogen molecule is in
excess of 200 MeV. At that energy it isn't
going to bounce off. It's going to embed itself in the hull material and
deposit all its energy, thereby ablating the
hull material, irrespective of its composition.

I think it's time we change the dream. We are not going to be leaving the Sol
system an
Pity the re-re-make of "Dune" release date has been delayed from December
2020 to October of 2021. We will probably encounter the TOET by then.

Ah, yes, the Stoned Ape Hypothesis.
I have been studying the Novelty Time Wave Theory of late. Melange is
definitely required. :)

Don’t you mean “folded space” ?
That sniff has to do with the spice, IIRC

This is exactly why starships travel in subspace.

At the melting point of Titanium it will radiate about 80 W/cm^2, compared to
the calculated 500 kW/cm^2 kinetic energy.

Looks like your angle is radiative cooling.
Plus, speaking of angles - the full kinetic energy of the particles would not
be transferred to the titanium.

According to wiki (https://en.wikipedia.org/wiki/Interstellar_medium) the
