More than likely, since the letter is simply a piece of paper, he put it under his costume while he traveled through time. The letter would be inside of his speed-force generated aura and thus protected from the ravages of travel the same way his costume is. "The Flash's body is surrounded by what he calls his "speed force aura". This aura protects him ...

Four Reasons 1. Krypton's Red Sun Under a red sun, Superman's abilities are reduced to human-like levels. Depending on who's writing the story, it could take anywhere from a few seconds to a day or so but either way, it's unlikely he'd be "super" enough to do anything helpful for very long. 2. Kryptonian Skepticism While the details surrounding Krypton's ...

Spoilers At the end of Flashpoint Paradox, after Flash goes back in time at the end to fix everything, all of the heroes have their costumes slightly changed because it is now the New 52 timeline. It seems really annoying but it's just a minor change now and has no real significance. It's just a costume update based on the New 52 designs so that the new ...

She's tried, more or less. In the 2012/2013 Superman story arc H'El on Earth, Supergirl is wooed by a Kryptonian named H'El and is convinced to attempt to go back in time to stop the destruction of Krypton. Unfortunately, H'El's method of time travel involves creating an explosion large enough to wipe out the entire solar system. Supergirl plays an ...

The answer to every question of this nature is "because the few people capable of doing it know that it's a terrible idea." Your question seems to make the assumption that we're only talking about the CW television shows that make up the "Arrowverse" (e.g. you mention her sister, her relationship with The Flash, etc.) If we restrict ourselves to that ...

Because of the time boom, as mentioned by Reverse Flash: It wouldn't have changed what happened before her murder. Bruce's parents, Clark's landing. Oh, but it did. Break the sound barrier and there's a sonic boom. You broke the time barrier, Flash. Time boom. Ripples of distortion radiated out through that point of impact... ......

* Spoilers * To understand, you'd need to read the comic - the movie leaves quite a few things out. In the comic, Professor Zoom understood the very point you bring up... that if he went back in time and erased The Flash from existence, it would prevent his own existence as well. To get around that, he came up with something diabolical: If you liked the ...

It appears that he utilized the Speed Force (since Batman mentioned the costume is supposed to reduce friction) and its ability to grant him control over kinetic energy (and even his own molecular structure) to generate a mass of static electricity, possibly ball lightning, that allowed him to short the bombs circuitry before it exploded. This is why Hence ...

The reason as stated in Flashpoint was a bottled Speed Force. The speed force trickles out gravimetrically causing the rotation to accelerate. No Barry no massive speed force drain

A recent addition to the Flash's powers has been the ability to transfer vibration or "Speed Force" energy from one object to another. This corresponding transfer brings a certain amount of kinetic energy with it. He has the ability to subtract energy from objects as well. Think of it like a bullet without the need for the corresponding gunpowder charge ...

I believe the sort-of-official explanation is that the person who did the time travel and participated in the timeline shift retains memories of the previous timeline, and they are replaced by the new memories slowly. If I remember correctly that's even mentioned in the film, when he first talks with Thomas!Batman. Or am I mistaken?

Everytime Flash does a time jump,he creates an alternative timeline. The original timeline stays put as it is even if the past is changed... You can better take it as the burning of a matchstick. You can go back and stop yourself from doing that but in the present time, it has already burnt and therefore you create an alternate reality instead... Now,since ...
