Interstellar Travel Challenges 5

This episode focuses on many of the problems with travel between stars at relativistic velocities, like collision avoidance, radiation, ship geometry, armor, and point-defense.

We will also look at some of the possible engine types and discuss realistic maximum speeds they offer.

"Spaceship designs are never going to look very cool."
OBJECTION!
Anything with a rotating habitat is cool.

Isaac, I love and hate your videos.

On one hand they are informative, interesting, and funny.
On the other hand, any time I try to watch other futurism/space channels I feel like they are explaining things to me like I'm a basic idiot.

What I mean to say is thanks for actually adding some depth to your videos and not just spewing out 5 minute long videos that don't really teach or say anything. I have had more than my fill of bite size bullshit that is all over the internet these days.

good closed captions, good visuals, charts, using characters to introduce physics and propose solutions, that's a like from me. clearly you put a lot of time and effort into your work

You have a talent for making even the fantastic seem like an easy and mundane thing (in a good way that is) that is bound to happen eventually. Gives me hope for the long-term future of Humanity.

I like how you mentioned the Super Admiral now has hundreds of years of experience and still needs this stuff explained to her.

Thanks Isaac Arthur for the hours of great videos, i remember the first video i watched it was the fermi paradox video that was like 2 years ago. love the longer videos the best, i feel you can explain more detailed and are much more informative, i actually see tones of stuff in movies and anything where they refrence something i have learned from your videos and its nice to have that understanding.
THANKS AGAIN FOR YOUR AMAZING VIDEOS!

And I still love your accent so much. It's perfect to listen to while sipping whiskey and eating snacks.

The quality of the intellectual material is on par with the best in the field. btw you need not suggest subtitles or explanations, your communication is better than most people without an impediment. please slow down and explain some heavy parts, we love hour long videos. Thank you so much, Isaac, great work!

Issac Arthur, with all the crazy news lately, your channel is such a nice escape! Thanks for not being political. Jim

If you are sending out probes to new star systems, getting them to 99.9% light speed takes a huge amount of energy. But remember if your probe arrives 1 year sooner, your dyson sphere can be built 1 year sooner. So the energy invested in getting your spaceship to those speeds is more than repaid in that extra year of energy from the dyson sphere.
