## Top best answers to the question Â«How far can light travel through spaceÂ»

• 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.

FAQ

Those who are looking for an answer to the question Â«How far can light travel through space?Â» often ask the following questions:

### âť” How is the space industry growing in scotland?

• The industry itself is taking the lead when it comes to developing and growing the Scottish space industry. The Scottish Space Leadership Council (SSLC) brings together businesses in commercial space to increase opportunities, efficiencies and growth through collaboration, partnering and mutual support.

### âť” How long would it take for space shuttle to travel to mars?

• We've already launched a whole bunch of spacecraft to (or near) Mars, so we have a rough idea of how long it takes with current technology. Historically, the trip has taken anywhere from 128 days to 333 days, which is a huge length of time for humans to be on board a cramped spacecraft.

### âť” How long would it take to travel 1 lightyear in space?

This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year.

### âť” How long would it take to travel to mars in a space shuttle?

• The common travel time for spacecraft to Mars is six months, though there can be fluctuations around that depending on the launch opportunity and the mission requirements. To minimize time in space, they might use a high thrust engine with lots of fuel, which could reduce the travel time to four or five months.

### âť” How long would it take to travel to space in years?

• The speed that is desired to keep the space vehicle in motion is 11,200 m/s (25,000 mph). One year is 3.1 E 7 seconds. The trip, in Earth Years would take: 8.5 E 11 / 3.1 E 7 = 2.75 E 4 years = 27,500 years.

### âť” How much does orion span space hotel cost?

• Orion Span claims to reduce that to just three months â€” still a substantial amount of time to take off from work. Even with the \$9.5 million price tag, Orion Span is already collecting deposits (a cool \$80,000) for the first guests to spend time at their luxury space hotel.

### âť” How much would a space hotel cost?

So ISS's newest residents will probably just have to bed down wherever they can find a place to float their sleeping bags. For this privilege, each entrepreneur-astronaut will pay \$55 million.

### âť” Is space tourism feasible?

• For space tourism to be feasible, it must be relatively affordable and safe to the general public. Companies involved with space travel need to construct reusable spacecraft that do not negatively impact the environment with available finances.

### âť” Is space tourism possible?

• Space tourism will be a part of adventure tourism, at least in the beginning, but it will continue to expand as it increasingly becomes economically affordable. However, the realization of this projected enormous expansion will heavily depend upon the safety of space transportation systems.

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. In this case, some light is absorbed and lost as heat, just like sound.

According to NASA, "that gave RĂ¶mer convincing evidence that light spread in space with a certain velocity." He concluded that light took 10 to 11 minutes to travel from the sun to Earth, an...

Still, the narrow beam will spread out over long distances. Around 100 meters away from a red laser pointer, its beam is about 100 times wider and looks as bright as a 100-watt light bulb from 3 feet away. Viewed from an airplane 40,000 feet in the air -- assuming thereâ€™s no clouds or smog -- the pointer would be as bright as a quarter moon.

The direction of vibration in the waves is at 90Â° to the direction that the light travels. Light travels in straight lines, so if you have to represent a ray of light in a drawing, always use a...

The solar system sits some 26,500 light years from the galactic centre, about halfway along a spiral arm. We orbit the centre of the Milky Way about once every 240 million years.

More than 100 years ago, a famous scientist named Albert Einstein came up with an idea about how time works. He called it relativity. This theory says that time and space are linked together. Einstein also said our universe has a speed limit: nothing can travel faster than the speed of light (186,000 miles per second).

That is the equivalent of 1.03159504 x 10^10 kilometers (6.41 x 10^9 miles). This is the same distance as traveling to the moon almost 27,000 times. As of 2019, it had traveled ~147 AU and has continued to send data back to Earth. Traveling in space takes a very long time.

A law of science, determined by Albert Einstein, says nothing can travel faster than the speed of light -- 186,000 miles per second. The fastest object made by man, the Voyager spacecraft is travelling along at 11 miles per second. At that rate, the scientific probe Voyager, launched in 1977, would take 73,000 years to reach the nearest star.

The more modern value is 68 kilometers per second per megaparsec, plus or minus a couple, but close enough. I know, I know. You were probably following along just fine until that odd "per...

This bubble is astronomically large (literally), and currently spans approximately 200 light years. But how big is this, really, compared to the size of the Galaxy in which we live (which is, itself, just one of countless billions of galaxies in the observable universe)?

Is there a way to travel to intergalactic space?
• There are several hypothesized methods of carrying out such a journey, and to date several academics have studied intergalactic travel in a serious manner. Theorized in 1988, and observed in 2005, hypervelocity stars move faster than the escape velocity of the Milky Way, and are traveling out into intergalactic space.
What is orbital space tourism?

In space tourism: Orbital space tourism. The advent of space tourism occurred at the end of the 1990s with a deal between the Russian company MirCorp and the American company Space Adventures Ltd. MirCorp was a private venture in charge of the space station Mir. To generate incomeâ€¦.

When will the space hotel open?

#### 2027

The first ever commercial space hotel, Voyager Station, aims to open by 2027. Accommodating 280 guests and 112 crew members, the project is being planned by Orbital Assembly Corporation, a construction company run by John Blincow. Who was the first person to travel into space twice?
• Virgil "Gus" Grissom (1926-1967), first NASA astronaut to go into space twice; first person to go into space twice in a capsule -type spacecraft; would have been the first person to fly three times; died in the Apollo 1 disaster Guy LalibertĂ©, first Canadian space tourist.
Will space tourism be ever possible?

Space hotels are likely to be the next venture for many to support the space tourism sector. One company, Orion Span, has developed plans for the first-ever â€śaffordableâ€ť luxury space hotel called 'Aurora station'. Orion Span is looking to launch in 2021 and start welcoming guests in 2022â€¦ one giant leap for hotel life.
