what would be the effect of 2 nuclear explosions detonated next to each other?

Question

could it tear space /time

Answer 1

I wouldn't bet on it, "tear[ing] space /time"
Fusion bombs are ignited with a fission device, which is "2 nuclear explosions detonated next to each other" Such devices have been tested and we are all still here.

Answer 2

There have been issues raised as to whether the EMP from one such device would disable the detonation of a second nearby device, even if it was hardened against radiation.

That aside, two nuclear devices exploding nearly simultaneously would be no different, in character than two conventional explosives doing the same. If you bind more than on stick of dynamite, you get a bigger boom. The shock wave pressure profile is groomed by the ensemble's configuration and delay between detonations.

The difference for nuclear devices is that you have a pressure shock as well as an attendant thermal one and a radioactive release. Except for the disabling potential I started with, there probably would be nothing else that distinguishes this situation form a single detonation except for a multiplaction of scale and altered pressure and thermal profiles.

It would not tear space time. It would cause the expected damage locally and globally.

As to the reference another answerer made to the Manhattan Project, it is true that there was a minimal concern that the first detonation at Alamogordo could ignite the atmosphere in a chain reaction. Despite the overwhelming consensus that it was not likely, we should learn not to be coerced into similar reckless haste in the future. Judgment was clouded by irrational urgency and impatient egos.

Answer 3

Mostly like one big one. It's not going to tear space/time. It will do an extreme amount of damage. Interestingly, the scientists who developed the first nuclear weapons in the Manhattan project were not sure if the first nuclear explosion would set off a chain reaction that would explode the entire earth, but they took that chance anyway.

Answer 4

NUCLEAR infers a fission explosion, like uranium or plutonium.

THERMONUCLEAR infers a fusion explosion, like hydrogen.

Thermonuclear explosions are initiated with a nuclear device, so, for each thermonuclear explosion we have ever made, this situation has occurred.

Nuclear explosions are not as profound as fusion explosions.

We frequency observe two suns (which are super-sized fusion explosions) when they get caught in each other's gravity wells. They appear to spiral down into a single object without performing any fantastic effects on space and time.

My viewpoint is heretical to mainstream physics; by definition, as long as each nuclear explosion is active, it has established it own universe within its Event Horizon. Since each of these explosions is its own momentary universe, there is no tearing of space and time.

Answer 5

2 Nuclear explosions will cause a insanely massive damage,,

90 megaton war head can obliterate 30miles radius and send a blast wave over 100miles away knocking out everything on its path,,

imagine detonating 2 90megaton warhead....

Their blast wave will clash and amplify the damage by 20%(each warhead)

Conclusion: no Tearing of Space and time..

Answer 6

some people suggest that the exploding of nucler weapons is what attracted the attention of UFO's as they use a gravity drive to propel their spaceships and that the effect of a nuclear blast wold cause a gravity something to be able to be detected by them
