Can We Travel Faster Than Light? | Michio Kaku

For decades, scientists and science fiction writers have imagined the possibility of traveling faster than light, but according to Einstein’s theory of relativity, nothing with mass can exceed the speed of light. However, Michio Kaku explores theoretical ways in which humanity might one day break this cosmic speed limit. One of the most promising ideas is the Alcubierre Warp Drive, a concept that suggests bending space-time itself rather than moving through it. By contracting space in front of a spacecraft and expanding it behind, a ship could effectively "ride" a warp bubble, allowing it to reach distant stars without violating relativity.

Another concept involves wormholes, theoretical shortcuts through space-time that could connect distant points in the universe. If stable wormholes exist, they could allow near-instantaneous travel across galaxies. However, major challenges remain, including the need for exotic matter with negative energy, which has never been observed in usable quantities.

Quantum physics may also provide new possibilities. Quantum entanglement, often referred to as "spooky action at a distance," suggests that information can be transmitted instantaneously across vast distances. While this doesn’t allow faster-than-light travel for physical objects, it raises intriguing possibilities for future communication technologies.

Despite these ideas, the energy requirements and engineering challenges of faster-than-light travel remain immense. But as Michio Kaku suggests, what seems impossible today might become achievable with future breakthroughs in quantum mechanics, space-time manipulation, and advanced propulsion systems. Could the next great scientific revolution unlock the key to interstellar travel?

We will never travel as fast as light but we will bend space

[kevinglennN]

It’s so hard to believe that it’s been 90 years almost 100 ago since 1935 and just to have known people who were in their prime those days and are no longer here. It’s a little weird but yet pretty cool

[deanbardos]

Loved that he brought up lewis carrol, through the looki g glass. A personal inspiration. 😊

[johnb]

It must be so frustrating first discovering these things knowing the remainder of humanity are clueless

[RubenGamez-jh]

Except you have to survive the tidal forces that would rip you apart. Sheilds. You would need powerful shields. Powered by a flex capacitor and backed up by a verliam sphere.

If you travel thro a wormhole you don't travel faster than light you just travel a smallest distance. So you exit somewhere else in the universe and from someone on Earth it looks like you travelled X light years but you didn't, you travelled a much smaller distance inside the wormhole. The most intersting question is how would you exit the wormhole ? I mean if these are 2 blackholes connected then how would u scape the gravity of the 2nd black hole ?

[tonyjohnson]

If you can calculate, then manipulate two black holes to organize themselves back to back, exceeding the speed of light would be the epitome of a none issue.

[margobarranti]

The other side of forever is Wonderland… huh! Ill have to think that one over…maybe forever is wonderland…❤

[MichaelKoester-zh]

There's something that escapes a black hole the darkness that you see and if you try to say Darkness doesn't exist then how can you see Darkness even in the absence of light you still see dark it's the one thing that is truly everywhere in the universe you can't touch it but it's there

A 3rd way not mentioned: tachyons. Because of the E = MC-square relationship, one can think of matter as being like 'frozen' energy. My hunch is that one can, in turn, think of energy as being like 'frozen' tachyons. 'Frozen' tachyons always travel at the slowest possible speed - the speed of light in a vacuum. If a tachyon travels faster than light, it is said to be 'unfrozen' where it no longer interacts with the known universe. A blackhole is where captured photons 'die', being morphed into tachyons. A blackhole can then emit 'unfrozen' tachyons as a type of black hole radiation. (Like photons, a tachyon would have its own speed of tachyon limit within its 'tachyon spacetime' world.) Tachyons leaving a black hole can stretch or inflate space. Its field might even be what causes outer space to exist, allowing the separation of entangled dual particles/waves. Tachyon emission can further stabilize the blackhole, enabling it to outlive stars.

How could this help poor matter beings like us travel faster than the speed of light? Tachyons can be manipulated to create wormholes that fold space itself, reducing vast distances.

[kurosephiroth]

Well you also need to understand that the speed of light really only applies to beings in the 3'rd dimension. We are all made up of atoms, molecules and energy. The state of everything we are accustom to exists within our current understanding of spacetime. But, that doesn't mean there aren't other beings out there, that are built differently, with quantum fluctuations and vibrations creating an entity, existing outside of our relative space-time. We can only accelerate matter through space up to slightly less than the speed of light - that doesn't mean there isn't a different form of existence out there that isn't limited to the speed of light - we may just not be able to perceive it.

Michio Kaku, Brian Cox, me and a good bottle of Scotch is all I need

[Sevensisslingsausages]

A blackhole and wormhole are very different 😂 a blackhole will crush you into infinite density and makes you part of its mass

[GeorgeSoPro]

"Michio Kaku is out of control"

[vukkekovic]

Once I had an exam, and there was a question if anything can/will ever travel faster than light. my answer was yes, and I got the negative points on that question. I am still waiting an apology from my teacher.

[OptimusPrime-xx]

Folding the space time continuum is the second way.

[AtheR]

I used to be able to name 5 things faster than speed of light I forgot half now

[martinfedor]

If you go faster than light you will become time traveller.

[wilsonfrantine]

It's just me that sense that space and time are not just the same thing, but what we call time is an artifact of perspective? Mass, including us, can't move apart of the interaction between "materia" (what we call gravity) and such deslocation takes energy, the opisity side of mass in the e=mc^2 equation. The result of it is that our movement in space and the energy we expand creates the perception of time which is only the energy required to challenge gravity and that is why when you cut the path in a half you double the speed, because they are our sentience of the same thing. I'm not littered in Phisics, but from what people show me up to now, I see that time is just our perception of how mutch space bands

[JonGreen_UK]

Except that if you travel through a wormhole of that nature, you emerge reflected in one of your three dimensions. So the chirality of your molecules is also reflected. Bad news when it comes to sourcing any kind of nutrition outside of the ship that brought you through the wormhole, unless you luck out and find a planet where the life molecules have the same chirality as yours.
