how long would it take to reach the speed of light?

Question

Assuming it was possible to reach the speed of light, how long would it take to accelerate to 186,000 miles per second at the rate of acceleration that a human being could withstand for that period of time?

Answer 1

I'll forget the power requirements necessary and answer just based on if you could do it...it would take somewhere around 58 years accelerating at the speed that gravity affects us...9.8 meters a second. of course that isnt very fast, but thats how fast you'll fall in a vacuum here on earth....now if we kick that up to 2 g of acceleration, we're at 29 years, 3g around 19 years...i'd say we wouldnt be comfortable at more g's than that, in fact i wouldnt want to make a trip at 3 g's the whole way either would you?

Answer 2

The human body could never survive a speed remotely approaching light speed.

As an object's speed approaches the speed of light, it's mass increases to the point that the human heart would be unable to pump blood, among other things.

Answer 3

What rate would a human being be able to withstand.

But the speed of light is impossible to reach, it requires an infinite amount of energy

Answer 4

It would not be possible to reach the speed of light since light photons have almost no mass. We have huge masses and it would take foreever to reach the speed of 186,000 per second.

Answer 5

i think of a pair of your respondents have at a loss for words speed with acceleration. the respond is: it might desire to in no way happen. First, a primer in gravity. Gravity has the visual allure of a stress that attracts any 2 bodies with mass. The better the mass of the two physique, the more suitable the gravitational stress between those 2 products. once you drop an merchandise close to Earth, the quantity of stress between the object and Earth may well be calculated like this: F = GMm / r² the place G is the gravitational consistent, 6.67x10^-11 Nm²/kg², M is the mass of Earth in kilograms, m is the mass of the object in kilograms, and r is the area between their centers in meters. For all products falling close to the exterior of Earth, G, M, and r are same (or almost so contained on the topic of r), and can be simplified to g. g = GM / r² For products close to Earth's floor, g = 9.80 one m/s² So the stress pulling an merchandise in the direction of the middle of Earth is: F = mg in case you overlook air resistance, all products close to Earth's floor improve up downward at 9.80 one m/s². In different phrases, for each passing 2d, a freely-falling merchandise will improve its speed by utilising 9.80 one m/s. AN merchandise would not FALL AT a relentless speed (if we overlook air resistance). Now...with regard to the fee of sunshine. the fee of sunshine is the main suitable speed decrease of the universe. so a strategies as all of us comprehend, no longer something can surpass the fee of sunshine and not something with mass may even attain the fee of sunshine. that's with the aid of fact as an merchandise's speed will improve in the direction of c (the fee of sunshine), its mass additionally will improve. It takes power to enhance up an merchandise, however the extra vast some thing will become, the extra power it demands to enhance up it that next little bit. in case you stick to that good judgment each of how by way of, you will see that it might take endless power to enhance up some thing to the fee of sunshine. in view which you will no longer be able to have endless power, you could in no way attain c, inspite of a pair of portals that we could you fall consistently. you will get closer and closer to the fee of sunshine, yet in no way surely attain it. i'm hoping that facilitates. sturdy success!

Answer 6

Since it is impossible to reach that speed, there is only one answer possible, it would take infinite much time.
