Is space/time made of matter?

A little more than 100 years ago most people–and most scientists–thought of matter as continuous. A theory with the strange name of loop quantum gravity predicts that space and time are indeed made of discrete pieces. …

Does time exist without mass?

NO. At the beginning of our universe there was light speed energy and there was matter that had resting mass (matter) and thus could not travel at light speed. When the light speed energy zoomed away from matter it created a temporal dimension we call forward time.

What is a space without matter?

A vacuum is an empty place, which space nearly achieves. … But the vacuum of space is the opposite. By definition, a vacuum is devoid of matter. Space is almost an absolute vacuum, not because of suction but because it’s nearly empty.

Can things exist without matter?

No! Neither Time nor Space can exist without the Matter, aka the Universe made up of physical stuff. First, without the Matter there wouldn’t be anything capable to determine the existence of Time or Space. Secondly, Time can only be measured using Matter, namely, interactions between material objects.

Why does time and space exist?

Einstein’s general theory of relativity established time as a physical thing: it is part of space-time, the gravitational field produced by massive objects. The presence of mass warps space-time, with the result that time passes more slowly close to a massive body such as Earth.

Does time stop gravity?

If time paused or stopped, there would be no events. Gravity is the way particles with mass/energy mutually influence one another, altering their paths through space-time. If time stopped, nothing would change, gravity would be moot.

Can space and time be separated?

In the context of special relativity, time cannot be separated from the three dimensions of space, because the observed rate at which time passes for an object depends on the object’s velocity relative to the observer.

Is space matter Yes or no?

Everything that has mass and takes up space is matter. … They are non-matter. Basically, any type of energy or any abstract concept is an example of something that is not matter.

Does time really exist?

Time is a prime conflict between relativity and quantum mechanics, measured and malleable in relativity while assumed as background (and not an observable) in quantum mechanics. To many physicists, while we experience time as psychologically real, time is not fundamentally real.

How long is 1 hour in space?

there are no hours in space. an hour is a not too convenient unit that is 1/24th of one revolution by the earth on its axis of rotation. Earth gravity is not that strong so it should only dilate time by a little bit.

Why is time the 4th Dimension?

Time’s dimension is a line going from the past to present to future. Thus, time as the fourth dimension locates an object’s position at a particular moment. … The other dimensions allow you to move both ways. Hence, they separate time from spatial dimensions and call it a temporal dimension.

Does time exist in 5th dimension?

This dimension is time. Although we can’t really see time itself, the progression of distance is probably the closest you’ll get, and it does make sense in this simulation. … This became known as the Kaluza-Klein theory , which has the ultimate goal of connecting gravity and electromagnetic force into a fifth dimension.

Is an hour in space 7 years on Earth?

No. Time dilation is not a constant that is triggered simply as a result of being in space. For example, astronauts on the ISS do not experience 7 Earth years in one hour. Instead, clocks on the ISS run 0.007 seconds slower than clocks on Earth.

How is 1 hour 7 years in space?

The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.

Do you age slower in space?

We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved, and it can be warped by matter and energy. … And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.

How long is 1 year in space on Earth?

How long is 1 year in space compared to Earth? **One year in space would be 365 days /1 year on earth…..

How long is 1 day in space?

The definition of a day is the amount of time it takes an astronomical object to complete one full spin on its axis.
…

Planet Length of Day
Venus 243 Earth days
Earth 23 hours, 56 minutes

How long is 1 second in space?

The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space in one second, and is equal to exactly 299,792,458 metres (983,571,056 ft).

What happens if you spend 5 years in space?

Long-term exposure causes multiple health problems, one of the most significant being loss of bone and muscle mass. Over time these deconditioning effects can impair astronauts’ performance, increase their risk of injury, reduce their aerobic capacity, and slow down their cardiovascular system.

Can you fart in space?

The official verdict on gas in space: No burps, more farts, and no, you can’t use your flatulence to propel you around the shuttle.
