Destroying Asteroids

Actually it's gone down because most asteroids of that size have been mapped and we should be good for the next few hundred years.
The only thing close to that would be if the false vacuum theory is true. Then the entire universe would disappear into the true vacuum and it'd happen at the speed of light so you wouldn't even know that it happened til it happened. Fortunately it's unlikely as the universe was at a higher energy state during cosmic inflation and it were to happen it would have happened then.

This messing around with Apophis is very suspect. NASA has been adamant for months that the astroid is not a risk to earth impact in 2029, but why would they go to such massive expense to alter the trajectory? And what if this attempt, back-fires and it actually 'moves' closer to Earth and get's sucked in by gravity?
I think Apophis is truly a threat and NASA is lying to us.
Here's a prophetic, biblical angle......

A little basic research would answer all those questions. It's next nearest approach isn't for 100 years. It also changes the trajectory of the smaller asteroid orbiting another. And that's about the size that they would probably have to deflect in the future. It doesn't change the orbit of the larger asteroid. You're still talking several million miles so it wouldn't move it that much closer to earth. The reason for doing it on the smaller one is that they can detect the change in the orbit easier. If you did it to just a lone asteroid, it's much harder to see the change in orbit relative to the sun instead of relative to another asteroid. And it's not NASA that did the calculation for the asteroid's orbit, those were done by other organizations and many other observatories who did their own calculations and observations. And while the $330 million project sounds like a lot, it's not really that much compared to NASA's annual budget which is over 22 billion.
This is what happens when people no longer understand science and math.
Here’s another recently discovered comet named Leonard. Interesting that it will leave the solar system. Is there one that left some other solar system and it on its way? Get the tin foil hat out!

The technology to hit a moving asteroid in outer space has lots of applications, for instance, making sure you can hit every ICBM out there, guaranteeing a true nuclear umbrella. The phone’s ringing. It’s Putin.
It hit! Right on time. Here the last few screen shots before it hit the moonlet.
off the NASA website.

Then here the last shots before it hit the asteroid’s moonlet and the screen turned red as the spacecraft got obliterated. This was all live ( but with a 45 second delay to reach earth.)

Here is a shot about 10 minutes earlier when the camera on the spacecraft showed both the asteroid and the moonlet orbiting it. It then zoomed past the asteroid and hit the moonlet. Amazing.

Right. The further away, the smaller the nudge needs to be.

The conjecture of the destructive meteor theory has been disputed recently by a number of scientists.
The degree to which extinction was caused by a meteor has been argued, but the iridium layer is incontrovertible, as is the crater. Earth was hit.
Saw news story where NASA showed that the spacecraft hit the moonlet, not the main asteroid.
They said the moonlet was about the size of the Washington Monument, so it wasn't very large. But the spacecraft's mass isn't much either, so they wanted to impact something small enough in hopes to actually detect a change of its path of motion.

"...Also at El Peñon, the researchers found 52 species present in sediments below the impact layer and counted all 52 still present in the layer above it, indicating that the impact has not had the devasting biotic effect on species diversity as has been suggested. “Not a single species went extinct as a result of the Chicxulub impact,” Keller said.
In contrast, she noted, at a nearby site known as La Sierrita where the K-T boundary, iridium anomaly and mass extinction are recorded, 31 out of 44 species disappeared from the fossil record at the K-T boundary.
“Keller and colleagues continue to amass detailed stratigraphic information supporting new thinking about the Chicxulub impact and the mass extinction at the end of the Cretaceous,” said Richard Lane, program director in the National Science Foundation’s division of earth sciences, which funded the research. “The two may not be linked after all.”
Keller suggests that the massive volcanic eruptions at the Deccan Traps in India may be responsible for the extinction, releasing massive amounts of dust and gases that could have blocked sunlight, altered climate and caused acid rain. The fact that the Chicxulub impact seems to have had no effect on biota, she said, despite its 6-mile-in-diameter size, indicates that even large asteroid impacts may not be as deadly as imagined.
She regards the latest evidence as sufficiently convincing and compelling to allow her to move on and investigate further the evidence for Deccan volcanism as being at the root of dinosaur extinction. But she does not expect her teams’ present work will stop the raging debate at the heart of this controversy.
“The decades-old controversy over the cause of the K-T mass extinction will never achieve consensus,” Keller said. But consensus, she added, is not a precondition to advancing science and unraveling truth. “What is necessary is careful documentation of results that are reproducible and verifiable,” she said."

So until further evidence, I am going with the volcanic eruptions theory, which also spews iridium.
There are over 100 theories for why the dinosaurs went extinct. Some of these include theories such as the idea that dinosaurs died out due to carbon dioxide accumulation from volcanic eruptions, global warming/cooling, epidemics, or from predation by egg-eating mammals. The fact that there are so many different theories suggests that researchers do not really have a final solution to the question.

As for the iridium theory, the iridium layer is not as well-defined as previously once thought. There are currently over 100 known (Cretaceous–Paleogene) or K-Pg iridium anomalies. There is much circular reasoning about the K-Pg boundary. That is, dinosaurs died out at the K-Pg boundary. How is this defined? Well, any rock layer with dinosaur remains or tracks supposedly proves that it’s below the boundary.

Macrofossil evidence for a rapid and severe Cretaceous–Paleogene mass extinction in Antarctica - Nature Communications
Debate surrounds the causes, timing, and effects of the Cretaceous-Paleogene mass extinction, 66 Ma. Here, using new collections of marine macrofossils from Seymour Island, Antarctica, the authors show that the extinction was both rapid and severe in the high southern latitudes, contrary to...

Dinosaur Decline Started Long Before Asteroid Impact
The dinosaurs — the so-called tyrants of the Mesozoic era — weren't exactly thriving during their last few million years on Earth, a new study finds. The new analysis of the dinosaur family tree reveals that dinosaurs were disappearing even before the asteroid hit about 65.5 million years ago...
