Can a flashlight reach space?

The photons leave the flashlight and they immediately start to spread out in a cone-shaped beam. Provided that they don’t hit anything, each individual photon travels through space forever. So the answer to your question is, “It depends on both the flashlight and on the size of your ‘eye'”.

How far does light travel in space?

Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.

How far can flashlights shine?

A 1000 lumen flashlight is quite bright and, depending on the lens or reflector design, powerful enough to reach a distance of 200 meters or more. This type of flashlight allows you to see objects from a far distance.

Can you travel on light?

So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.

How far away are the stars from a flashlight?

Even though the stars are very bright compared to a flashlight, they are also very far away (most stars are many light years away, and one light year equals 10 trillion kilometers or 6 trillion miles).

Why can’t a flashlight be seen from Outer Space?

If you mean why can’t the flashlight be seen from space then there is a simple answer, it is too small an amount of light. However lets hypothetically assume that the torch had enough light output to be seen from outer space. There are so many stars that are in our universe, that in theory the night sky should be completely white. But it isn’t.

How far can light travel through space?

This is why light from distant stars can travel through space for billions of light-years and still reach us on earth. However, light can also travel within some materials, like glass and water.

Can we see light from a torch in space?

Some of the light does make it out to space, but it is so weak, you would not be able to see it, A scientist in the ISS with a powerful telescope might just be able to see it but probably not. Light spreads out as it travels away from your torch and follows the inverse square law doubling the distance results in a quarter of the intensity.
