Speed Comparison: Faster Than Light

From the average human walking speed to traveling the universe, we compare different speeds using Space Engine. We start around Earth and progressively head towards the stars, the galaxy and the entire universe.

It's crazy how 1 light yeah/S looks so slow still, gives you a sense of how unimaginably gigantic space is.

[thibs]

Your terrain reference changes everything, making it totally impossible to actually visual the difference.

So it's settled then: *Cameraman is the fastest.* Called it!

300 light years per seconds is the speed that I clicked on this video when it popped up on my YouTube feed.

This guy's content is freaking awesome

1:46
I had chills for a second while imagining this as a bomb/laser beam from a spaceship directed at earth

Thanks to the cameraman for filming this

[sirannikus]

You forgot to add 'ludicrous speed' at the end.

All I want is to travel and explore the universe. That is my biggest dream. If there is some afterlife, I hope it’s a sandbox mode where you can do anything I want haha

Universe: Good one buddy, with a speed of 9.6 septillion km/hr, u just travelled a small part of me

Space engine is great game, surprised how I don't play it much anymore.

[AndrewNovitsky]

Our imagination can go faster than a speed of light

[cdrcb]

At 1 light speed no stars shouldn’t be moving

2:41 I've been playing too much Elite Dangerous that I was half-expecting an interdiction noise going at that supercruise speed

[chopper]

This is nice but it’s really hard to get a frame of reference when the nothing here is human scale ….
I understand most of these speeds are not to human scale but that’s the point right

[aki_]

Cameraman has done great work. I can’t imagine how hard was it for him

[toplespecah]

That background music sounds incredible

[sofyavideoclips]

This is really quite mindblowing overall. Real fantastic stuff in here. I wonder anyway is there the end to our universe or do we humans just not get the right perspective of the universe apart from aliens that are way more developed than us??🧐

[pzychpth]

I absolutely love Space Engine, Ive just recently bought it and Ive played it a few times just flying around and exploring, Ive always had dreams about flying around the universe and now I literally can and its mind blowing. 😁

You missed one thing. At the speed of light, time stops, so any distance is covered instantaneously in the traveler's reference frame. Outside of that reference frame, the amount of time that would have passed is the amount of light years. So if I get into a spaceship and travel to a star that's 100 light years away at the speed of light, for me, the trip will be instantaneous, but on Earth 100 years would have passed. If I then turn around and head back to Earth at the speed of light, my trip will again be instantaneous, but another 100 years would have passed on Earth, for a total of 200 years. Also, from the star, I would have had to plot a course to where Earth would be in 100 years, not where it was that moment, even though for me the trip would be instantaneous. This is why traveling at the speed of light (or very close to it) is more than enough to get anywhere in the Universe within a human lifetime. Time dilation takes care of that. Of course, depending on the distance traveled, in an Earth inertial reference frame, tens, thousands or millions of years will pass.
