SO apart from Scientists having a ball what is the benefit to mankind to justify these costs ??

How fast was the comet traveling through space?

Why settle for pseudoscience when real science explains it quite well?
Bright flash = lots of photons.
Fine dust = impact ejecta.
No need for EU nonsense.

@killer fish ... you also know they are dirty snowballs right? ;) extra bowl of fail for you!
@ActiveStorage .... the fine dust is a sign if "electrical-etching" ... as per the pre-strike flash ... google Holoscience

just wiki deep impact. btw no one from nasa expected the explosion to be that big. and no one expected these highly pulverized super fine dust particles.

yeah, im not a scientist. maybe the flash was just due to a kinetic impact
peace

true. but same logic aplies to kinetic. There is no gases or liquids out there. I looked up Heat of fusion for silicon (most common material out there) is 50.21 kJ·mol−1 and its Heat of vaporization is 359 kJ·mol−1. On top of that you need energy to make the vaporized material become ionized so we get the flash and visible light. The flash is huge. So the volume of ionized gas have to be large. now the velocity of the impactor was around 10.3 km/s with mass 370 kg.

some ppl outside of the main stream scientific community believe there was an intense electric discharge phenomena. due to this unconventional idea about comets being electrically charged celestial bodies.
ActiveStorage 2 years ago
some say it wasnt just a "sheer kinetic force" that created the explosion
