Why are exposure times so long if light travels so fast?

.... The light from those distant stars is simultaneously released from the star AND absorbed by your eye... at the same time. ..........

Which would suck. Big time.

Because you'd end up seeing everything in the entire universe........ all at once. You'd end up blind.

Which is why I prefer the Capt Kirk version of physics. "Ok we're here. Trot out the green alien babes!"

The way it works is an actual upside down image of your picture is projected onto the sensor of the camera. Think of it like the image is being burned into the sensor. The brighter the image, the shorter the amount of time needed to burn it in and the dimmer the image then the longer.

This has gotten quite amusing. I think what everyone is trying to say is that you are WAAAAAAYYYY overthinking this. Rather than reading online, pick up your friggin camera and go shoot something. Put it in manual, change one setting at a time, and look at what the camera actually captures according to what you make it do. Shoot the exact same shot only changing the shutter speed. Then set a 2 second exposure and have someone walk through the shot. You will quickly figure out what happens.

By the way, the theory behind actually traveling the speed of light has made huge jumps since scientists began figuring in for hanging those fake bull balls from the back of their hypothetical vehicles.....

If light travels so fast, why did I waste 16 minutes of my life reading this thread?

Just imagine it from the perspective of the poor photon that is stuck in this thread for eternity.

My photon left two days ago.

Have you printed up flyers with a picture and posted them at the local gas station? Would be a nice change of pace from the "Have you seen this cat" stuff I normally see when I stop for gas.

A couple of weeks ago, I practiced catching 2 million-year old photons, along with many of much more recent vintage. Had to prime my rhodopsin chomophores tho.

How did you KNOW they were 2 million years old? Did you card them?

Well, because they were all of the Andromedan family. Those guys act old. Sirian photons are mere toddlers, at 8-ish, whereas the Pleiadians were at least 400 years old.
