MASSIVE Plot Hole:- One 1960s Nuclear Bomb Destroys The Entire Planet!

This is the "fiction" in science fiction.

It is not a bomb of the 60ies but thousands of years in the future after the evolution of the apes. So why not?

Apes talk in this movie and the bomb is the part that bothered you?

It was an alpha omega bomb, and in a part of the dialog they referenced it had a cobalt case. A cobalt bomb Is a fusion or fission bomb that had a casing of the metal cobalt-59 which is not radioactive. Once the bomb explodes and vaporizes the cobalt-59, the cobalt reforms over time as colbalt-60 which is very radioactive. The micro dots of cobalt-60 spread everywhere and have a 5 year half-life. It only takes breathing in a single dot or being exposed to kill you. It’s the original dirty bomb.

So, assuming the only living areas on the planet are where the apes and mutants are, ya, it could end the world due to the fallout.

But, it went off underground, which is not where you want a dirty bomb to go off, you want it to explode high up, so it rains down fallout on everything.

Hahahahaha
"Massive Plot Hole" and all you can come up with is the Nuke??
As someone else pointed out it is Science Fiction, SOOO some thing are -- Made Up
THAT's what Fiction means

Here's one for you
The Apes are advanced enough to have reloadable automatic weapons
BUT
Only have muzzle loading cannon??
Ever try firing really old cartridges?? doesn't work that well

Do they ever indicate what century mankind destroyed itself? The first film appears to occur 701 years after they launched.

Apenheimer

Wouldn’t the fact that it went off underground have massive consequences? I can see it having a chain reaction leading all
The way to the earths core.
