@kaiko_bosnaa4: Theoretical physicist Michio Kaku claims time travel is now only an engineering challenge. Renowned theoretical physicist Michio Kaku famously asserted that what was once confined to the realm of fantasy and science fiction - time travel - has officially crossed over into the territory of practical science, stating that it is now "simply an engineering problem." Far from being a mere trope of Hollywood screenplays, the manipulation of the space-time continuum is firmly grounded in the laws of general relativity. Einstein's equations already permit the theoretical existence of wormholes and closed time-like curves, suggesting that the universe's fabric can indeed be bent to connect different points in history. Rather than debating whether the laws of physics forbid such journeys, modern theoretical physicists are increasingly looking at the astronomical power requirements and advanced materials needed to actually build a gateway. However, transitioning from mathematical equations to a physical time machine presents engineering challenges on an almost incomprehensible scale. To warp the fabric of space-time, scientists would need to harness the energy equivalent of an entire star or master the manipulation of "negative energy"- an exotic quantum state that is notoriously difficult to produce in stable quantities. Additionally, any potential time-travel technology would have to contend with the complex paradoxes of causality that have kept thinkers debating for decades. While humanity is still far from constructing a functional portal to the past or future, Kaku's provocative insight shifts the conversation: the pursuit is no longer about proving the impossible, but about finding the engineering solutions to build it. source: Kaku, M.

ok but because the the planet's and our solar system and everything is moving through it I can't go back to even a few days ago because you have to know the exact position the earth is ln at the exact at a specific time at your entry and exit point get the maths wrong and you'll exit in deep space!

Time is relative to the individual…. You can only position yourself theoretically to see or observe the past, not interact with it and if you travel to the future, you aren’t really travelling to the future, your using time dilation to slow your local time while the rest of the planet ages faster. To really change time you need to reverse entropy on a universal scale, can’t be done.

Ich bin nicht schlau.... Ich kann nur die eine Sprache.... Mehr nicht..... Jetzt kommt das Wort Universum... Uni heisst einzigartig..... Versum heißt für mich vielfalt... Zusammen heisst es einsigartig mit Vielfalt..... Schon sehr interresant.... Dann wird das Wort Raum noch mit einbezogen..... Und Welt..... Also Weltraum, oder weltenraum..... Welt ist da leben Wesen.... Jetzt würde ich behaupten Raum ist ein Würfel mit vielen Türen..... Und jeder Raum hat sein eigene Dichte.... So könnte ich immer weiter machen..... Ich bin sehr begrenzt mein Wissen ist sehr gering.... Habe aber eine sehr grosse Fantasie.... Wo würde es uns hinführen...... Merkst du was..... Danke für den Dialog....

I don't need engineering to timetravel,my soul has done it multiple times ,but only forward not back.

Bending spacetime is theoretically possible. 💯%

Le passé n'étant pas modifiable, le visiter en combinaison spatiale. Aucune interaction n'étant possible, même pas sûr que ces photons périmés puissent être perçus par nos yeux ou caméras.

Time travel is a security problem and food for next clown show.

Prince Tabitha :

time is not a place we can travel through. tick tock time is only measurement. nothing is passing somewhere. reality is continuously transforming. clocks measure and compare those transformations. reversing a clock or motion does not reverse reality’s continuity. the past does not exist as a location somewhere in the universe. so there is no past location to return to. time travel theory may begin with the wrong assumption about what time actually is.
