that could have sustained life. We get to shoot a laser at the rock. Now why did we do that? Instead of having to go over and touch every rock and taste every rock... like we said before, we can actually fire the laser at the rock, burn the surface of the rock and look at the gas that comes off. And from that gas we can see what the chemical composition of that rock is. What are the elements that are there.

though it can be mitigated by the use of sunblock. But since the dermal cells are relatively stable, much of the ink will remain deep in the skin for a person's whole life. But if tattoos are embedded in your skin for life, is there any way to erase them? Technically, yes. Today, a laser is used to penetrate the epidermis

Advances in laser technology continue to make vision correction surgery more effective and accessible.

We have the device over here. And we're going to show you, instead of the kill laser, which will be a very brief, instantaneous pulse, we're going to have a green laser pointer that's going to stay on the mosquito for, actually, quite a long period of time; otherwise, you can't see it very well.

And they're not the only ones. There are gravitational wave detectors spread across the world. These L-shaped instruments have long arms, whose exact length is measured with lasers. If the length changes, it could be because gravitational waves are stretching and compressing the arms.
