That closing paragraph(s) really made me feel warm inside.

Thanks, Phil.
Keep up the great work.

Actually I just checked and apparently the Helios probe at slightly more than 70km/s is the fastest manmade object, as it approached the Sun.

Speeds of about 30 km/s should be attainable, the current chemical rockets allowing for about 10 km/s and the remainder from gravitational slingshots.

Mendel - OK, we made light bulbs, but we didn’t make the photons that travel so fast (we provided the energy for them, but they were made by a piece of hot tungsten). Besides, photons are not macroscopic. Generally, if you can see something as a discreet entity without a microscope, it can be considered macroscopic.

BA, a much more lively report than New Scientist (although I read theirs first). Keep up the good work.

quote “The Sun is orbiting the center of the Galaxy at 200 km/sec (120 miles/sec). Thatâ€™s faster than any man-made macroscopic object has ever moved. No rocket, no hyper-accelerated bullet, nothing we have ever made of any size has gone that fast”

Well let’s see, people have made lightbulbs, right? lightbulbs emit light, light travels faster than 200km/sec. We also have particle accelerators, but I guess individual neutrons aren’t macroscopic objects Where do you draw the line of microscopic object vs macroscopic object? I guess several micrometers? (duh)

Muchas Gracias, Senior.
