Since dabura can move at near light speed only because he constantly pushes himself with his technique. And as domain amplification turns off your technique, dabura wouldn't be able to keep moving at this speed. And as moving at extreme speeds create too much air resistance dabura would eventually slow down exponentially in microseconds making his attack no longer a threat.

Gojo was able -from what I have understood - to speedblitz kenjaku. Since Kenjaku didn't show any proper physical reaction when gojo attempted to attack him. And by looking at the panel we can see that gojo was flexing his arm and preparing to land the punch meaning he got very close to kenjaku and was ready to punch his ass.

To calculate this speed feat we will calculate kenjaku reaction time from his fight against yuki and choso.

Calculating kenjaku reaction time:

PB was fired 3cm away from kenjaku head

PB travels faster than sound:

Low end : 343 m/s ( mach 1)

High end : 515 m/s ( mach 1.5 )

The time required for PB to cover the distance:

Low end : 8.7 × 10^-5 s

High end : 5.8 × 10^-5 s

- Kenjaku reaction time is obviously shorter than the time required for PB to travel this distance. So, I will estimate his reaction time at 20%-30% of the original duration.As If Kenjaku took longer to perceive the attack, he would have had to move at an insane speed to dodge PB in the short time remaining.

Kenjaku reaction time:

Low end : 2.6 × 10^-5 s

High end : 1.16 × 10^-5 s

Calculating gojo speed :

As we said gojo was able to cross the distance between him and kenjaku, before kenjaku could physically react. Which means that gojo should crossed this distance in a duration equal to kenjaku reaction time at most.

Since we don't know the exact distance traveled by gojo before sukuna be able to block him I would estimate it at 6-8 m. Since as I already said, gojo was on his way to land a hit on kenjaku as shown by the panel.

Gojo Speed calculation:

Low end : mach 672

High end: mach 2010

If sukuna attacked yuji here instead of aurafarming he would easily break yuji simple domain and then yuji would be killed easily with the sure hit

Bro's strength and speed are closer to the calamities than anyone else but his durability doesn't help at all

The CSM fans forgot we have this mf

Q. Was it impossible to block Itadori's "Dismantle" (Kai) with Domain Amplification?

A. It's not that it was impossible, but if you fail to neutralize even a little bit of the technique's effect, Amplification weakens rapidly from that spot, leaving you exposed to "Dismantle" anyway—making it extremely dangerous.

By the way, Kurusu's and Todo's cursed techniques act directly on cursed energy itself, so Domain Amplification cannot block them either.

So as stated by gege not being able to neutralize the technique completely leads to weakening the amplification ( keep in mind sukuna wasn't able to fully neutralize a weakened red btw )

Because blue creates a negative space which forces everything forcefully to collapse into a single point. And at the center of blue this gradient would be theorically infinite. Correct me if I am wrong

He had seen with his own eyes Choso's ability to produce thousands of liters of blood, yet he decided to treat him like a normal person and saying, "Meh, he must be suffering from blood loss."
