Cool page. Spent many minutes side-scrolling. As usual, I draw the line at Uranus.
I have always thought that as well. Plus if something goes wrong you are days and not months away from earth
Does uranus emit gases?
...it is, after all, one of the gaseous planets.
By comparison, if that same signal has to travel the entire circumference of the globe -- about 25,000 miles -- it takes a little over a tenth of a second.
The average human reaction time to perceive an event and respond to it is somewhere in the range of .5 to .75 seconds.
So a light impulse can travel around the world at least 5 times before we even know it left.
Say what you will, for human purposes on this planet, the speed of light is plenty fast.
I suppose if you’re happy being stuck in antiquity, the speed of light is adequate.
Amazing. Thanks.
Very cool. The one thing that stood out to me in all that empty space, there is plenty of room for parking.
Bfl
We have a different name for it: Reality.
You are way off. The nearest spiral galaxy is 2.5 million light years away, not 13.
Lol! Sorry. Meant 13 BILLION light years!
...and I was referring to the farthest yet detected galaxies.
Cool.
'Engage warp drive, make it so.'
That is great. It really makes its point.

One year, as a 2nd grade teacher, I did a unit on space. We mainly focused on our solar system. We had several models of the earth and moon in the classroom to different scales. I modified an old BASIC program I found so that it would give you your weight on the sun, all the planets and our moon. We made a scale model of the planets down the hallway using some old globes and different sized balls. The sun just had to be part of its arc on the wall at the end of the hall - but we could not make the distances to scale. At first I thought, “Well, if I just make the scale small enough we could do it.” If I remember correctly, even using a golf ball as the sun, the nearest planet was going to be something like a quarter of a mile away and smaller than a bb. I gave up on that idea pretty quickly. It was one of those “Ah ha!” moments.
My 18 year old and I watched the whole thing. Do you know how hard it was get a millennial to sit still that long?! It was hard for me, too!
