I know certain species have something in their genes that won't allow them to evolve anymore such as the mule. Are humans the last stop in their evolutionary chain?

Let's say, we built technology and depend on it..
Such as how we built cars and automated machines to help transport us
from place to place, and thus we walk less, we become obese
and become out of shape. Thus we depend on cars and machines
such as those, because now we cannot walk far distances because
we are fat. Now let's say in the future we eventually develop
such extensive technology that we depend on it 24/7 to survive.
And let's say that we eventually pay less attention to skills such as
modern enginnering or electronics. So in the future we depend
on a ridiculous amount of technology, enabling us to be
useless in essence, and than we also don't apply the effort
to learn essential skills in maintenance and innovation because
we're so lethargic.

One day an accident occurs and our technology is rendered
useless and we have no means to recover from it since
we are completely incapable of functioning without technology
and have no skills at all.

Is this a likely end to mankind?

If you are to model Light in terms of waves, then, sure it will have its wavelength and frequency, but if u were to model it in terms of particles, then as we know, massless particles do not have wavelengths/frequencies (no De broglie wavelength because there is no mass involved). So how come when finding the enerygy of a particular photon, the equation that we use involves frequency of light?

According to modern cosmological models, the visible universe appears to be made up of 4 - 6% "normal matter" while the remaining 94 - 96% is made up, disproportionately, of "dark matter" and "dark energy". Also, modern cosmology shows that immediately after the "big bang" there was only a tiny more matter created along with anti-matter. The ensueing annihilation of complimentary particles, converting matter and anti-matter into gamma radiation, left matter as the winning majority component of the current universe. But, is there any evidence that, actually, "annihilated" anti-matter still exist and is the constituants of "dark matter" and "dark energy"?

Most people answer that it is because sound travels so much slower than light. That explains the delay, not the duration. I belive we can tell a lot about the shape and length of the lightning bolt by the duration and character of the sound produced. Faint to loud and then faint again might mean horizontal lightning where the observer is more or less in the middle. Loud and then trailing off might mean it was angled away from the observer. Anyway, I have no scientific proof of any of this. =)
