Travelling At 99% of The Speed Of Light Looks Strange - Project Hail Mary's Space Warp [11:09]

Project Hail Mary is my favourite movie of the year, and while many people have made videos explaining time dilation due to travelling close to the speed of light, nobody has tried to visualise how the universe appears to warp due to relativistic aberration. I wanted to create these visuals to give you an idea of what it would look like at these speeds, even without a warp drive or hyperspace nothing looks right.

Scott Manley explores the visual distortions caused by relativistic travel, examining concepts like aberration, the searchlight effect, and Doppler shifting. Using simulations and visualizations, this analysis illustrates how the appearance of the cosmos changes when a spacecraft accelerates to speeds approaching that of light.

Prepare for LUDICROUS SPEED!!!

The fringes of unproven theoretical physics makes for the great science fiction that dominates the popular imagination. Sorry but the concept that a biological or mechanical entity can travel 99% of the speed of light is pure fantasy.

At that speed, I’d worry about hitting something, no matter how small.

Did this movie cover how inter-stellar molecular hydrogen would become deadly radiation if you plowed into it at that speed?

[Nateman]

Larry Niven used that interstellar hydrogen to power his ramjets. Was he right? Maybe , but his predictions of organ dealing were prophetic.

“Larry Niven used that interstellar hydrogen to power his ramjets. Was he right?”

Poul Anderson’s “Tau Zero” dwelt on the problem of high “c” speed and interstellar molecules.

I am of the opinion that no matter how smart we think we are we probably understand .000000001 percent of what there is to know and that the creator made it impossible for us to ever leave this solar system for a reason we probably don’t have the ability to even comprehend.

[Leaning Right]

A rocket traveling at 99% of the speed of light… possible, according to Einstein’s Theory of Special Relativity. But it would take an enormous amount of energy to accelerate to that speed.

[Leaning Right]

> we probably understand .000000001 percent of what there is to know <

No, says Dr. Fauci. He thought he knew everything. On the other hand, the great scientist Isaac Newton agrees with you.

[Getready]

Not to mention that the mass of the biological entities, eyeballs, brains, etc would be approaching infinity....(assuming relativity is true)...how would any simulation be able to envision how those effects would be perceived?

Doesn’t increasing the mass of anything, break the conservation of matter laws? What parts of the atom start increasing mass? Protons, neutrons, quarks, gluons? Or do they all increase mass proportionately?

If it takes infinite energy to move a physical object to the speed of light, would the universe collapse if all energy in the universe is used for that purpose?

[Governor Dinwiddie]

Let's Do the Time Warp Again.

[Leaning Right]

> If it takes infinite energy to move a physical object to the speed of light <

Yes, indeed. As speed increases, so does mass. This is true even at everyday speeds, but it is not something that we can notice. But at around 90% the speed of light, the effect becomes very noticeable.

"...travel 99% of the speed of light is pure fantasy."

More importantly, even if we travel at the speed of light, there is nowhere in the nearby universe we could get to in less than many hundreds of thousands or millions of Earth years...

Our galaxy is about 87,000 light years across...
Earth is about 27,000 light years from the center...
